Dutasteride 0.05%, minoxidil topical hair loss foam
from£29.99
A personalised topical hair loss foam containing dutasteride 0.05% and minoxidil 5%. Designed for adults who need a focused two-ingredient approach targeting the hormonal and circulatory drivers of pattern hair loss, with dutasteride at a clinically considered lower-strength concentration, in a format that fits more easily into daily life. Applied to the scalp once daily and absorbs quickly without dripping or residue.
Hair loss is easy to dismiss until it happens to you. The visible signs are familiar: thinning at the crown, a wider parting, a hairline drifting in the wrong direction. The less visible impact is often harder to carry. Confidence drops. Self-consciousness builds. Furthermore, the worry that things are getting worse, and that nothing tried so far has made a real difference, becomes part of daily life.
The problem with standard treatments
For many people, the frustration goes beyond the hair loss itself. It is about the experience of trying to treat it.
Standard topical hair loss liquids can be fiddly to apply. Drops trickle off the scalp before they have a chance to absorb. Sprays drift onto the face, the forehead, the pillow. Moreover, alcohol-heavy solutions sting on application and can leave the scalp feeling tight for hours afterwards.
After a few weeks of that, skipping a night feels less like failure and more like self-preservation. However, skipping nights is exactly what stops hair loss treatment from working.
Why this two-ingredient foam?
Pattern hair loss has more than one driver. DHT miniaturises follicles through the hormonal pathway. In addition, poor scalp circulation and reduced follicle activity then accelerate visible thinning.
This formula addresses both dimensions directly. Dutasteride 0.05% targets the hormonal driver at a clinically considered lower-strength compounded concentration. Importantly, it blocks both type 1 and type 2 5-alpha reductase for a more comprehensive approach to DHT suppression. Meanwhile, minoxidil 5% stimulates follicle activity and improves scalp circulation. Together, they form a considered two-ingredient approach. It is not a default combination, but a formula selected because clinical assessment and, where used, TrichoTest results indicate this is the most appropriate treatment for the individual.
Why a foam?
The foam format changes the daily experience of hair loss treatment. It is light, fast-drying, and easy to dispense exactly where you want it. There are no drips down the back of the neck, no spray drift onto the forehead, and no waiting around for a wet scalp to dry before bed. Crucially, the foam absorbs quickly and leaves no greasy residue, which makes it far easier to fit treatment into a normal morning or evening routine.
Many patients also find foam more comfortable on the scalp than liquid. The format spreads evenly through the hair, reaches the scalp directly, and does not leave the heavy, sticky feel that some liquid solutions can. For people who have given up on previous topical products because the experience was unpleasant, foam can be the format that finally lets them stay consistent.
Why 0.05% dutasteride?
The dutasteride concentration in this foam is 0.05%. This is a clinically considered lower-strength compounded concentration. Specifically, the prescriber selects it when clinical assessment indicates this is the most appropriate concentration. It often suits patients who are starting compounded dutasteride for the first time, those whose anti-androgen requirement is lighter, or those whose TrichoTest results indicate strong responsiveness to dutasteride at a lower strength. Alternatively, it suits patients who want a gentler entry point before considering whether a stepped-up concentration is needed. The concentration is not a default. Rather, it is a clinical decision made for you specifically.
A medically responsible route
At Courier Pharmacy, treatment starts with a proper assessment. Suitability is checked. Furthermore, the decision to prescribe this compounded foam is a clinical one, based on your scalp, your history, and your goals.

What is Dutasteride 0.05%, Minoxidil 5% topical hair loss foam?
This compounded topical hair loss foam contains dutasteride 0.05% and minoxidil 5%. It is designed for adults with pattern hair loss who need a focused two-ingredient approach. Specifically, it targets the hormonal driver of hair loss at a lower-strength dutasteride concentration and supports follicle activity. In particular, it suits those who want a lighter, faster-drying format than a traditional liquid, or those whose clinical profile indicates this combination is the most appropriate starting point or next step.
Two active ingredients working together to target DHT and support follicle activity
Foam format that absorbs quickly, dries fast, and fits easily into daily routines
Dutasteride at 0.05%, minoxidil at 5%, a clinically considered lower-strength combination
May suit people with androgenetic alopecia with a lighter anti-androgen requirement, or those starting compounded dutasteride for the first time

Pattern hair loss is personal
Pattern hair loss is common, but that does not make it any less personal. Many people first notice extra shedding, reduced density, or a hairline that seems to be quietly retreating. Many then try a product that does not match their biology, see little result, and quietly give up. However, that is not because treatment cannot work. Rather, they were never on the right treatment to begin with.
A formula for people who want a lighter format and a lower-strength anti-androgen approach
This foam is aimed at people who need a carefully considered two-ingredient approach. Specifically, it addresses the hormonal and circulatory drivers of pattern hair loss with dutasteride at a lower-strength concentration. Furthermore, it is particularly relevant for those whose TrichoTest results indicate strong dutasteride responsiveness at a lower concentration alongside a strong minoxidil response profile, those who are new to compounded dutasteride, and those who have struggled to maintain a daily routine with liquid topical solutions.
The goal of treatment
Hair loss affects more than appearance. It chips away at confidence. Indeed, it makes ordinary moments feel oddly loaded. A harsh bathroom mirror. A photo taken from an unexpected angle. A windy day when you would rather not think about what is visible.
The goal of treatment is not perfection. Instead, it is to slow loss, support healthier growth, and help you feel more in control. Crucially, this comes with a plan that addresses the full picture at the most clinically appropriate strength and a format that makes daily use something you can actually stick to.
The foam advantage
When the format is the problem
For many patients, the active ingredients in standard hair loss products work in principle, but the daily experience of using them gets in the way. Liquid solutions take time to apply, sit wet on the scalp, and can drip onto pillows, clothes, and faces. Sprays drift. Drops trickle. The whole process can feel like an admin task that has to be slotted in twice a day.
What foam removes
The foam format removes most of those friction points. The product dispenses cleanly into your palm or fingertip, sits where you place it, and absorbs into the scalp within a minute or two. As a result, there is no waiting for it to dry, no worry about it migrating onto your face, and no greasy residue left behind.
The active ingredients are unchanged. Only the format is different. Sometimes that difference is enough to turn an inconsistent routine into a sustainable one.
Why tolerability and ease drive outcomes
A treatment only works if you use it consistently. If the daily experience of applying it is uncomfortable or impractical, consistency breaks down. Therefore, the foam format exists to remove that barrier. It makes it possible to maintain the kind of steady, sustained daily routine that a two-ingredient hair loss formula requires. Anything that makes consistent application more achievable directly improves the chances of a good outcome.
Why the format choice matters clinically
The foam is clinically relevant as well as practically convenient. By making consistent application easier, it supports the kind of long-term compliance that clinical evidence consistently identifies as one of the most important predictors of treatment success. The most carefully chosen ingredients in the world are not much help if the bottle ends up at the back of the bathroom cabinet.
Why compounding?
What compounding means
Compounding means a medicine is prepared to order by a licensed pharmacy for an individual patient. It is not a mass-produced one-size-fits-all product. In the UK, this sits within a regulated framework and should only be supplied when clinically appropriate.
Why compounding matters for this formula
Some people choose this compounded foam because no standard licensed product combines dutasteride at 0.05% and minoxidil 5% in a foam format. This specific combination, at a lower-strength dutasteride concentration, in a format that absorbs quickly and fits into a busy life, is what their clinical profile and lifestyle require. Others come to compounding because liquid products have been impractical and they want their two active ingredients delivered in a more convenient vehicle. Others still want the clinical flexibility to start with this combination and expand or adjust their formula over time.
Personalised medicine in practice
Hair loss is not identical from one person to the next. The right combination of ingredients, concentrations, and format for one patient is not right for another. Compounding makes it possible to prescribe dutasteride 0.05% and minoxidil 5% together as a foam. This formulation simply does not exist in any standard licensed product. The medicine is shaped around the patient, not the other way around.
Why this two-ingredient combination can be the right choice
Some patients need both mechanisms addressed: DHT suppression and follicle stimulation, at a lower-strength dutasteride concentration. Unlike finasteride, dutasteride blocks both type 1 and type 2 5-alpha reductase, delivering a more comprehensive reduction in DHT. Think of dutasteride as taking the foot off the brake, more completely than finasteride can. Minoxidil then works alongside it, stimulating follicle activity and improving scalp blood flow.
For patients whose TrichoTest results indicate strong responsiveness to dutasteride at a lower concentration alongside a strong minoxidil response via the SULT1A1 pathway, this two-ingredient foam may be the most clinically efficient approach. It is also a sensible starting point for patients new to compounded dutasteride, where stepping up later remains an option if needed.
If tretinoin or other ingredients would add further benefit, or if dutasteride needs to be adjusted over time, TrichoTest and clinical assessment will guide that decision. Importantly, compounding makes either path possible.
TrichoTest: personalising the approach
TrichoTest reduces guesswork. It is a pharmacogenetic test that analyses 26 genetic polymorphisms linked to nine key treatment pathways relevant to hair loss. Rather than prescribing from standard protocols alone, TrichoTest combines your genetic profile with your medical history. As a result, it predicts which ingredients, dosages, and delivery methods are most likely to work for your biology.
How the TrichoTest informs this formula
This two-ingredient foam draws on multiple TrichoTest pathways simultaneously. The sulphotransferase (SULT1A1) pathway predicts minoxidil response. Specifically, patients with high SULT1A1 expression are strong responders to minoxidil and may benefit particularly from its inclusion at 5%. Meanwhile, the anti-androgen metabolism pathway identifies how effectively a patient responds to dutasteride and whether 0.05% is the most appropriate concentration for their genetic profile.
TrichoTest can identify all of these factors before treatment begins. Consequently, the prescriber arrives at the lower-strength dutasteride concentration with clinical confidence, rather than defaulting to it or arriving at it only after months of trial and adjustment.
How the TrichoTest informs this formula more broadly
If TrichoTest identifies that a different dutasteride concentration would be more appropriate for the individual’s anti-androgen requirement, the prescriber can adjust accordingly. Similarly, if results suggest that finasteride might be more appropriate than dutasteride, or that tretinoin or additional ingredients would add meaningful benefit, the prescriber can incorporate these from the outset or over time.
The nine pathways TrichoTest analyses
Prostaglandins and sulphotransferase, how you process minoxidil and latanoprost
Anti-inflammatory response, your reaction to glucocorticoids and immunomodulators
Anti-androgen metabolism, how effectively you respond to dutasteride, finasteride, and 17?-oestradiol
Circulation stimulation, response to vasodilators
Collagen synthesis capacity
Insulin-like Growth Factor (IGF-1) response
Vitamin absorption: A, B7, B9, B12, C, D, E
Mineral absorption: zinc, magnesium, iron, selenium
Antioxidant needs and oxidative stress profile
Beyond ingredient selection
TrichoTest also identifies nutritional gaps and metabolic factors that affect hair health independently of topical treatment. For example, if genetic variants reduce zinc or iron absorption, the prescriber can recommend targeted supplementation alongside this foam. As a result, treatment moves from guesswork towards something shaped by your actual biology.
TrichoTest does not guarantee results. However, it gives the prescriber better information to decide whether this specific two-ingredient foam at 0.05% dutasteride is right for you, or whether something different would serve you better.
The Gro hair loss range
What is the Gro brand?
Gro is the compounded hair loss range created by Courier Pharmacy and Medical Mojo. It exists because hair loss treatment should not feel one-size-fits-all.
Some people want a traditional liquid spray, direct, efficient, and familiar. Others prefer a foam. Meanwhile, others need an alcohol-free and propylene glycol-free base because their scalp reacts to standard excipients. Gro brings those options together under one brand, matching treatment to the person using it, not the other way around.
Each Gro product comes in a 30ml bottle designed to last one month. Every option costs £29.99 for up to three active ingredients, less than £1 a day.
Why Gro is different
Gro was built around three practical goals:
Choice of formulation: topical liquid, topical foam, or Trichosol solution (propylene glycol free and alcohol free)
Personalisation: single, dual, and triple-ingredient combinations across multiple concentrations
Better tolerability: every format is designed to reduce the friction that stops people from maintaining their routine
The three formulation types
Topical hair loss liquid: a traditional spray solution containing alcohol and propylene glycol. Well-established, with efficient scalp penetration. Chosen by patients who want a direct, familiar format.
Hair loss foam: lighter, faster-drying, and easier to apply without dripping. Chosen by patients who want clinical results in a format that fits more easily into daily life. This is the formulation described on this page.
Trichosol topical solution: propylene glycol free and alcohol free. Designed for patients with sensitive or reactive scalps who need a gentler base.
Ingredients used across the Gro range
Depending on the product selected, Gro formulations may include:
Dutasteride
Finasteride
Minoxidil 5%
Tretinoin 0.01%
These can be prescribed alone or in combination, and at varying concentrations, depending on the individual treatment plan.
In simple terms
Gro makes personalised hair loss treatment accessible and liveable.
You get a 30ml bottle for one month, £29.99 pricing, up to three active ingredients at a concentration chosen for you, and a choice of liquid, foam, or Trichosol alcohol-free and propylene glycol-free solution. If you want a treatment that fits your scalp, your sensitivities, and your treatment history, rather than a generic protocol, the Gro range gives you more than one route without making the choice unnecessarily complicated.
This is a Prescription Only Medicine. You can request it from courierpharmacy.co.uk by completing a quick online consultation, reviewed by a UK-qualified prescriber for suitability and safety. If appropriate, Courier Pharmacy will dispense the compounded foam and deliver it discreetly.

Dutasteride 0.05%, Minoxidil 5% foam — Active ingredients
Dutasteride 0.05%
Dutasteride is a 5-alpha reductase inhibitor. Unlike finasteride, which selectively blocks type 2 5-alpha reductase, dutasteride blocks both type 1 and type 2. As a result, it delivers a more comprehensive reduction in the conversion of testosterone to dihydrotestosterone, or DHT, the key hormonal driver of androgenetic alopecia in susceptible hair follicles. At 0.05%, this is a clinically considered lower-strength concentration. It is not a default, but a considered choice based on the individual's profile, history, and TrichoTest results where used. The concentration is not a compromise. Rather, it is a clinical decision made for the individual.
Minoxidil 5%
Minoxidil is a topical vasodilator and follicle stimulant. It supports hair growth by prolonging the anagen (growth) phase of the hair cycle, improving blood supply to follicles, and stimulating follicle cells to produce thicker, healthier hair. At 5%, this is the standard compounded concentration for adults with pattern hair loss.
Why the foam format matters
The foam format is also clinically relevant. It dispenses precisely, absorbs quickly, and does not drip onto the face, clothes, or pillow. Consequently, patients can apply this two-ingredient formula comfortably and consistently, which is one of the most important factors in whether any hair loss treatment succeeds over time.
What is the Dutasteride 0.05%, Minoxidil 5% foam used for?
Pattern hair loss in men and women
This product treats pattern hair loss, also called androgenetic alopecia. In men, this often appears as a receding hairline or thinning at the crown. In women, it may present as diffuse thinning or a widening parting. The aim is to support hair retention and encourage healthier growth where clinically appropriate.
The problems of hair loss
The practical problem is visible thinning. The internal problem is the loss of confidence that builds quietly alongside it. Moreover, the deeper issue is that people should not have to feel dismissed or left to navigate treatment alone for something that so clearly affects daily life.
Who this formula is for
Some patients come to this foam because their clinical profile indicates that both drivers of hair loss, hormonal and circulatory, need to be addressed with dutasteride's dual-pathway DHT suppression at a lower-strength concentration, in a format that fits into a busy life. Others arrive because their TrichoTest results demonstrate strong dutasteride responsiveness at a lower concentration alongside strong SULT1A1 activity. As a result, this two-ingredient foam becomes the most clinically efficient approach.
Others still come because previous liquid topical products were too messy, too time-consuming, or too easy to skip. Here, the foam removes that barrier while dutasteride at 0.05% addresses their specific anti-androgen needs as a lighter starting point. In all cases, a compounded foam at dutasteride 0.05% and minoxidil 5% offers a more considered, personalised path than anything available off the shelf.
How does the Dutasteride 0.05%, Minoxidil 5% foam work?
Pattern hair loss is driven by multiple overlapping processes. This formula targets two of the most important directly.
Dutasteride: blocking the hormonal signal more completely
In pattern hair loss, follicles gradually shrink under the influence of DHT. Dutasteride blocks both type 1 and type 2 5-alpha reductase, reducing the conversion of testosterone into DHT more comprehensively than finasteride. At 0.05%, the concentration reflects a clinical judgment that this lower-strength dose is right for the individual. Think of dutasteride as taking the foot off the brake, suppressing DHT production across both enzymatic pathways, reducing the hormonal pressure that drives follicle miniaturisation over time.
Minoxidil: stimulating the follicle
Minoxidil is a potassium channel opener and vasodilator. Applied topically, it improves blood flow to follicles, prolongs the growth phase of the hair cycle, and stimulates follicle cells to produce thicker, healthier hair. Importantly, it works through an entirely different mechanism from dutasteride, addressing the circulatory and follicle-stimulating side of the equation rather than the hormonal side. Think of minoxidil as waking up the follicles, improving the conditions at the scalp so that existing follicles can produce more and healthier hair.
How do you use the Dutasteride 0.05%, Minoxidil 5% foam?
This formulation is a topical foam and should only be used exactly as prescribed. The usual direction is:
Apply approximately half a capful of foam to the scalp once daily, massaging gently into the areas of thinning until absorbed.
A format that fits your life
The foam dispenses cleanly into your fingertip and sits where you place it. It does not run, drip, or drift. As a result, you can apply it to specific areas of thinning quickly and confidently, without worrying about product migrating onto your face, your hands, or your clothes. The foam absorbs into the scalp within a minute or two, leaving no greasy or sticky residue, so you can carry on with your morning or evening routine without delay.
The right formula for you
Because this is a compounded medicine, the prescriber selects each ingredient and concentration based on your individual clinical profile and, where used, TrichoTest results. The 0.05% dutasteride concentration reflects a clinical judgment that a lower-strength anti-androgen approach is right for you. Minoxidil at 5% is the standard compounded concentration. The formula may adjust over time, stepping the concentration up or down, or adding tretinoin if indicated, as your treatment plan evolves.
Building a routine that works
Many people find it easiest to apply as part of their morning or evening routine. Because the foam dries quickly, it can fit into either, depending on what suits your day. Wash and dry your hair beforehand if you can, dispense the foam into your fingertip rather than into a wet palm, and massage gently into the areas of thinning. Applied consistently at the same time each day, treatment has the best possible conditions to work.
What to do if you miss a dose
Resume at the next usual time. Do not apply extra to make up for it. Consistent daily use over months matters far more than compensating for a missed application.
Dutasteride 0.05%, Minoxidil 5% foam — Warnings and precautions
Who should not use this product
This product is not suitable for everyone. Extra care is needed if you are pregnant, trying to become pregnant, breastfeeding, have a scalp condition affecting absorption, or have a history of allergy to any ingredient in the formulation.
Dutasteride warnings
Dutasteride affects hormone pathways. Women who are pregnant or may become pregnant must not use this product, as it can affect male foetal development. Men with a history of prostate cancer, BPH, or elevated PSA levels need careful assessment before starting. Specifically, dutasteride lowers PSA levels, which may mask early prostate cancer. Therefore, baseline PSA screening may be required. The prescriber will discuss these risks during consultation.
Minoxidil warnings
Minoxidil is a vasodilator. Patients with a history of cardiovascular disease, low blood pressure, or cardiac conditions need careful assessment before starting. Although systemic absorption is lower with topical use than oral minoxidil, cardiovascular status will still be reviewed.
A note on concurrent treatments
If you are using other topical hair loss agents alongside this foam, disclose this during consultation. Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance.
Compounded does not mean casual
The foam format and two-ingredient formula do not reduce the need for proper prescribing review. The same thorough safety and suitability checks apply here as with any other prescription treatment. A full medical history, including cardiovascular status, prostate health, pregnancy status, previous medication reactions, and liver function where relevant, will be reviewed during consultation.
Dutasteride 0.05%, Minoxidil 5% foam — Side effects
Common side effects
Common side effects may include scalp irritation, dryness, redness, itching, flaking, or temporary shedding early in treatment. The foam format is generally well tolerated and absorbs quickly. However, it does not eliminate the possibility of local reactions entirely. Early shedding is common when starting minoxidil. Specifically, it occurs as follicles shift through the hair cycle and usually settles within a few months.
Dutasteride-related effects
Dutasteride at 0.05% topical strength may cause sexual dysfunction in some patients, including reduced libido, erectile dysfunction, or ejaculation disorders. These effects are uncommon with topical application, and at this lower strength they are reported less frequently than at higher concentrations. However, they have been reported. Mood changes, depression, or anxiety have also been documented. The prescriber will discuss this during consultation. Report mood changes, persistent sexual dysfunction, or any other concerning symptoms promptly.
Minoxidil-related effects
Topical minoxidil may cause unwanted facial hair growth if the product spreads beyond the scalp. The foam format reduces this risk because it stays where it is placed, but it does not eliminate it. Therefore, apply only to the scalp and avoid contact with the face. Systemic effects are uncommon with topical use but can include dizziness, palpitations, fluid retention, or low blood pressure.
When to seek advice
Seek advice if you develop chest pain, dizziness, palpitations, swelling, marked irritation, signs of allergy, severe mood changes, persistent sexual dysfunction, or unwanted hair growth in areas other than the scalp.
Dutasteride 0.05%, Minoxidil 5% foam — Drug interactions
Why interactions matter with this formula
Both active ingredients carry interaction considerations. Therefore, thorough review before starting is essential.
Dutasteride interactions
Dutasteride is metabolised via the CYP3A4 pathway. Strong CYP3A4 inhibitors may increase dutasteride levels. By contrast, enzyme inducers may reduce them. Although topical absorption is lower than oral dutasteride, relevant medicines will be reviewed during consultation.
Minoxidil interactions
Topical minoxidil may have an additive effect in patients taking antihypertensive medicines, potentially causing blood pressure to fall further. Patients taking medicines for cardiovascular conditions, blood pressure, or fluid balance should discuss this with the prescriber before starting.
Other scalp products
Other scalp treatments, harsh exfoliants, or irritating cosmetic products may increase the risk of local reactions. Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. Therefore, all current products should be disclosed during consultation.
Dutasteride 0.05%, Minoxidil 5% foam — FAQs
How long does it take to see results?
Hair loss treatment needs patience. Most people need several months of consistent use before visible improvement becomes apparent. Early shedding in the first few weeks is common with minoxidil and is not a sign that treatment is failing. The foam format makes consistent daily application easier, and consistency is what supports the outcomes treatment depends on.
Is this suitable for both men and women?
It may suit some adults, but the prescriber will assess this carefully. Women who are pregnant or trying to become pregnant must not use this product, as it contains dutasteride, which is contraindicated in pregnancy. Suitability is always assessed individually.
Why does this formula contain two ingredients rather than three?
Some patients need dutasteride and minoxidil together without tretinoin at this stage. This may be because the prescriber wants to assess response to this combination before expanding the formula, or because clinical judgment indicates that two ingredients are the most appropriate approach. If tretinoin or other additions are indicated over time, the formula can be adjusted.
Why is the dutasteride concentration 0.05%?
0.05% is a lower-strength compounded dutasteride concentration. The prescriber selects it when clinical assessment, and where used, TrichoTest results, indicate a lighter anti-androgen requirement, strong dutasteride responsiveness at a lower concentration, or a sensible starting point for patients new to compounded dutasteride. It is not a default. Rather, it is the appropriate concentration for the individual being treated.
Can the dutasteride concentration be increased later if needed?
Yes. One advantage of compounded treatment is flexibility. If clinical review shows that a higher dutasteride concentration would be more appropriate over time, the prescriber can step the formula up to 0.1% or 0.2%. Equally, if the lower strength is producing the desired effect, there is no clinical reason to change it.
Why is this formula a foam?
Foam absorbs quickly, dries fast, and does not drip or drift. For patients who have struggled to maintain a daily routine with liquid topical products, foam can make consistent application much easier. As a result, comfort and convenience drive the consistency that good outcomes depend on.
How is dutasteride different from finasteride?
Both are 5-alpha reductase inhibitors that reduce DHT. Specifically, finasteride selectively blocks type 2 5-alpha reductase. Dutasteride blocks both type 1 and type 2, producing a more comprehensive reduction in DHT. TrichoTest can help identify which is the more appropriate anti-androgen for the individual's genetic profile. The prescriber will discuss the most suitable option.
Can tretinoin be added to this formula later?
Yes. One of the advantages of compounded treatment is that the formula can evolve over time. If clinical assessment or TrichoTest results indicate that tretinoin or other ingredients would add meaningful benefit, the prescriber can adjust the formula accordingly. Discuss this during your consultation or at review.
What is compounding and why does it matter?
Compounding is the preparation of a medicine to order for an individual patient by a licensed pharmacy. This specific two-ingredient combination at 0.05% dutasteride in a foam format does not exist in any standard licensed product. Therefore, compounding is what makes it possible.
Can I use it if I have struggled with liquid hair loss products before?
Quite possibly. The foam format avoids the dripping, drying time, and residue that make liquid products hard to keep up with. Suitability still needs to be assessed by a prescriber. However, for patients who have struggled with the practicality of liquids, foam is often a more sustainable option.
How can TrichoTest help with this treatment?
TrichoTest analyses 26 genetic markers across nine key pathways. Specifically, it helps the prescriber identify whether dutasteride is the most appropriate anti-androgen, whether 0.05% is the right concentration for the individual's anti-androgen metabolism profile, and whether minoxidil response is likely to be strong via the SULT1A1 pathway, all before treatment begins.
Does TrichoTest guarantee the right treatment?
No. It reduces guesswork and supports more informed prescribing, but it does not guarantee results. Genetic testing works best alongside clinical assessment and your personal treatment history.
Will I need a prescription?
Yes. This is a Prescription Only Medicine. A UK-qualified prescriber must review suitability before supply. The consultation can be completed online at courierpharmacy.co.uk.
Can I stop if I see improvement?
Do not stop or change treatment without advice. Hair loss often returns to its previous pattern if treatment stops, even when results have been encouraging.
What is the Gro hair loss range?
Gro is the compounded hair loss brand from Courier Pharmacy and Medical Mojo. It offers liquid, foam, and Trichosol formulations, all priced at £29.99 for up to three active ingredients, less than £1 per day.
How much does this cost?
£29.99 for a 30ml bottle, designed to last around one month. Less than £1 per day.
How long does a 30ml bottle last?
Around one month when applied as directed: approximately half a capful of foam applied to the scalp once daily.
What is the difference between liquid, foam, and Trichosol?
Liquid is a traditional spray solution containing alcohol and propylene glycol. Foam is lighter, faster-drying, and easier to apply without dripping. By contrast, Trichosol is a propylene glycol free and alcohol free option for patients with sensitive or reactive scalps. All are available across the Gro range.
Is foam better than liquid or Trichosol for this formula?
It depends on your scalp and your previous experience with topical treatments. Foam is often the most appropriate choice for patients who want a clean, fast-absorbing application that fits into a busy daily routine. The prescriber can help you decide which format suits you best.
Can I use other hair loss products at the same time?
Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. Therefore, disclose all current treatments during consultation.
I have a heart condition, can I use topical minoxidil?
Disclose any cardiovascular history during consultation. The prescriber will assess suitability carefully. Topical minoxidil carries lower systemic absorption than oral forms. However, cardiovascular status is always reviewed before prescribing.
What if I have had problems with dutasteride or finasteride before?
Disclose this during consultation. Any previous adverse effects from either anti-androgen are essential information for the prescriber to assess your suitability safely.
