Finasteride 0.05%, Minoxidil 5% in Trichosol (propylene glycol and alcohol FREE) topical hair loss solution — Product description
The problem with hair loss
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 moving in the wrong direction. The less visible impact is often harder to carry. Confidence drops. Self-consciousness builds. 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 sting on application. The alcohol hits the scalp before the product has had a chance to absorb. The propylene glycol leaves a tight, uncomfortable residue that lingers for hours. After a few weeks of that, skipping a night feels less like failure and more like self-preservation.
Skipping nights is exactly what stops hair loss treatment from working.
Why this two-ingredient combination?
Pattern hair loss has more than one driver. DHT miniaturises follicles through the hormonal pathway. Poor scalp circulation and reduced follicle activity then accelerate visible thinning.
This formula addresses both dimensions directly. Finasteride 0.05% targets the hormonal driver at the lowest available compounded strength. Minoxidil 5% stimulates follicle activity and improves scalp circulation. Together, they form a carefully considered two-ingredient approach — 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 Trichosol?
The Trichosol base removes propylene glycol and alcohol entirely. No stinging. No tight scalp after application. No alcohol odour. Just two active ingredients, carried in a vehicle the scalp is far more likely to tolerate comfortably — applied night after night, for as long as treatment is needed.
Why 0.05% finasteride?
The finasteride concentration in this formula is 0.05%. This is the lowest available compounded strength. The prescriber selects it when clinical assessment indicates that a cautious starting approach to anti-androgen treatment is the most appropriate choice.
Whether because the patient is new to finasteride, TrichoTest results suggest a lower anti-androgen requirement, or clinical judgment indicates that the most conservative available concentration is right for this individual. Starting at 0.05% is not starting weak. It is starting right for you.
A medically responsible route
At Courier Pharmacy, treatment starts with a proper assessment. Suitability is checked. The decision to prescribe this compounded solution is a clinical one — based on your scalp, your history, and your goals.

What is Finasteride 0.05%, Minoxidil 5% in Trichosol topical hair loss solution?
This compounded topical hair loss solution contains finasteride 0.05% and minoxidil 5% in a Trichosol base that is completely free from propylene glycol and alcohol. It is designed for adults with pattern hair loss who need a focused two-ingredient approach — targeting the hormonal driver of hair loss at the lowest available finasteride concentration and supporting follicle activity — particularly those who need a gentler base because standard topical products have caused irritation, those new to finasteride who want to begin cautiously, or those whose clinical profile indicates this combination is the most appropriate starting point.
Two active ingredients working together to target DHT and support follicle activity
Propylene glycol free, alcohol free Trichosol base for a more comfortable daily experience
Finasteride at 0.05%, minoxidil at 5% — the lowest available finasteride concentration in a clinically considered combination
May suit people with androgenetic alopecia who are new to finasteride or have a lower anti-androgen requirement, whose scalps have reacted to standard topical bases
Safe prescribing still matters — hair loss treatment needs proper screening, review, and follow-up
Part of the Gro hair loss range, designed for personalised treatment at less than £1 per day
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 — not because treatment cannot work, but because they were never on the right treatment to begin with.
A formula for people who need a cautious start in a gentler base
This Trichosol solution is aimed at people who need a carefully considered two-ingredient approach — addressing the hormonal and circulatory drivers of pattern hair loss at the most cautious available finasteride concentration — in a base their scalp can genuinely tolerate. It is particularly relevant for those new to finasteride who want to start at the lowest available concentration, those whose TrichoTest results indicate a lower anti-androgen requirement alongside a strong minoxidil response profile, and those who have previously reacted to alcohol or propylene glycol-based products.
The goal of treatment
Hair loss affects more than appearance. It chips away at confidence. 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. It is to slow loss, support healthier growth, and help you feel more in control — with a plan that starts at the right point for you and a base that makes daily use something you can actually stick to.
The Trichosol advantage
When the vehicle is the problem
For patients who have reacted badly to standard topical hair loss solutions, the problem is not always the active ingredients. Often it is the vehicle carrying them. Alcohol causes stinging on application and dries the scalp significantly over time. Propylene glycol is a common cause of contact irritation, particularly in patients with already sensitive or reactive scalps — and it is a standard excipient in most off-the-shelf hair loss products.
What Trichosol removes
The Trichosol base removes both of these excipients entirely. The result is a solution that absorbs without stinging, does not dry the scalp, and does not leave the tight or uncomfortable residue that causes so many people to abandon their routine. The active ingredients are unchanged. Only the vehicle is different — and when starting finasteride at its most cautious available concentration, making sure application is comfortable from the first night matters.
Why tolerability drives outcomes
A treatment only works if you use it consistently. If the daily experience of applying it is uncomfortable, consistency breaks down. The Trichosol base exists to remove that barrier — making 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 Trichosol vehicle matters
The Trichosol base is clinically relevant as well as practically comfortable. It removes the excipients most likely to cause scalp irritation — making it possible for patients to apply their treatment consistently, which is one of the most important factors in whether any hair loss treatment succeeds over time.
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 solution because no standard licensed product combines finasteride at 0.05% and minoxidil in a Trichosol base — and this specific combination, at the lowest available finasteride concentration, in a vehicle the scalp can actually tolerate, is what their clinical profile requires. Others come to compounding because standard topical bases have caused irritation and they need their two active ingredients delivered in a gentler vehicle. Others want to start cautiously at the lowest available finasteride concentration, with the flexibility to step up over time as their treatment plan evolves.
The Trichosol base addresses the tolerability concern directly. It removes both propylene glycol and alcohol — the two most common causes of topical scalp irritation — without reducing the effectiveness of either active ingredient.
Personalised medicine in practice
Hair loss is not identical from one person to the next. The right combination of ingredients, concentrations, and vehicle for one patient is not right for another. Compounding makes it possible to prescribe finasteride 0.05% and minoxidil 5% together in a Trichosol base — a formulation that simply does not exist in any standard licensed product — when clinical assessment indicates that this is the most appropriate approach. The medicine is shaped around the patient, not the other way around.
Why this two-ingredient combination at the lowest finasteride concentration can be the right choice
Some patients need both mechanisms addressed — DHT suppression and follicle stimulation — but want finasteride to begin at the most cautious available concentration. Finasteride at 0.05% turns down the hormonal signal as carefully as compounding allows. Minoxidil stimulates follicle activity and improves scalp blood flow. For patients whose TrichoTest results indicate a lower anti-androgen requirement alongside a strong minoxidil response via the SULT1A1 pathway, this two-ingredient Trichosol combination may be the most clinically considered starting point.
If the finasteride concentration needs to increase over time, or if tretinoin or other ingredients would add further benefit, TrichoTest and clinical assessment will guide that decision. 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 to predict which ingredients, dosages, and delivery methods are most likely to work for your biology.
How the TrichoTest informs this formula
This two-ingredient formula draws on multiple TrichoTest pathways simultaneously. The sulphotransferase (SULT1A1) pathway predicts minoxidil response — patients with high SULT1A1 expression are strong responders to minoxidil and may benefit particularly from its inclusion at 5%. The anti-androgen metabolism pathway identifies how effectively a patient responds to finasteride — and whether 0.05% is the most appropriate starting concentration for their genetic profile.
TrichoTest can identify all of these factors before treatment begins — allowing the prescriber to arrive at the lowest available finasteride concentration with clinical confidence, rather than defaulting to a standard starting point that may not match the individual’s biology.
How the TrichoTest informs this formula more broadly
If TrichoTest identifies that a higher finasteride concentration would be more appropriate for the individual’s anti-androgen requirement, the prescriber can adjust accordingly. If results confirm that 0.05% is a well-matched starting point, treatment can begin with confidence. If tretinoin or additional ingredients would add further benefit, these can be incorporated 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. If genetic variants reduce zinc or iron absorption, the prescriber can recommend targeted supplementation alongside this Trichosol formula — moving treatment from guesswork towards something shaped by your actual biology.
TrichoTest does not guarantee results, but it gives the prescriber better information to decide whether this specific two-ingredient Trichosol formula at 0.05% finasteride 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. Some prefer a foam. 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.
Trichosol topical solution — propylene glycol free and alcohol free. Designed for patients with sensitive or reactive scalps who need a gentler base. This is the formulation described on this page.
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.

Finasteride 0.05%, Minoxidil 5% in Trichosol — Active ingredients
Finasteride 0.05%
Finasteride is a 5-alpha reductase inhibitor. It reduces the conversion of testosterone to dihydrotestosterone, or DHT — the key hormonal driver of androgenetic alopecia in susceptible hair follicles. Unlike dutasteride, finasteride selectively blocks type 2 5-alpha reductase. At 0.05%, this is the lowest available compounded concentration. It reflects a clinical decision that the most cautious approach to anti-androgen treatment is the most appropriate starting point for this individual — not a lesser option, but a considered choice based on their profile, history, and treatment goals. Starting at 0.05% is not starting weak. It is starting right for you.
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 Trichosol vehicle matters
The Trichosol base is also clinically relevant. Standard hair loss solutions typically rely on alcohol and propylene glycol as delivery vehicles — both of which are common causes of scalp irritation. The Trichosol base removes these entirely, making it possible for patients to 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 Finasteride 0.05%, Minoxidil 5% in Trichosol solution 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. 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 formula because their clinical profile indicates that both drivers of hair loss — hormonal and circulatory — need to be addressed, but finasteride should begin at its most cautious available concentration, in a base their scalp can actually tolerate. Others arrive because their TrichoTest results demonstrate both a lower anti-androgen requirement and strong SULT1A1 activity, making this two-ingredient Trichosol combination at the lowest finasteride concentration the most clinically considered starting point. Others still come because previous standard topical products caused too much irritation to use consistently — and the Trichosol base removes that barrier while the cautious finasteride concentration gives them a gradual, well-monitored introduction to anti-androgen treatment. In all cases, a compounded Trichosol solution at finasteride 0.05% and minoxidil 5% offers a more considered, personalised path than anything available off the shelf.
How does the Finasteride 0.05%, Minoxidil 5% in Trichosol solution work?
Pattern hair loss is driven by multiple overlapping processes. This formula targets two of the most important directly.
Finasteride: blocking the hormonal signal
In pattern hair loss, follicles gradually shrink under the influence of DHT. Finasteride blocks type 2 5-alpha reductase — reducing the conversion of testosterone into DHT at the follicle. At 0.05%, the concentration reflects a clinical judgment that the most cautious available approach is the right one for this individual. Starting at the lowest available dose is not starting weak. It is starting right for you. Think of finasteride as turning down the hormonal signal — reducing the DHT-driven pressure that causes follicles to miniaturise over time, beginning at the most considered available strength.
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. It works through an entirely different mechanism from finasteride — 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 Finasteride 0.05%, Minoxidil 5% in Trichosol?
This formulation is a topical solution and should only be used exactly as prescribed. The usual direction is:
Apply 1ml to the scalp daily using the dropper bottle.
A dose you can place precisely
The dropper bottle gives you direct control over where the solution goes. You direct it to the areas of thinning, not across the entire scalp. No spray drift. No product landing where it is not needed. In a Trichosol base, the solution sits comfortably without the sting of alcohol or the heaviness of propylene glycol — allowing both active ingredients to be applied reliably, night after night, without the discomfort that causes people to skip doses.
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% finasteride concentration reflects a clinical judgment that the most cautious available starting approach to anti-androgen treatment is right for you. Minoxidil at 5% is the standard compounded concentration. The formula may adjust over time — stepping the finasteride concentration up if indicated, or adding tretinoin or other ingredients — as your treatment plan evolves.
Building a routine that works
Many people find it easiest to apply as part of their evening routine — after a shower, before bed. The Trichosol base makes the application experience far more comfortable than a standard alcohol or propylene glycol-based product. Applied consistently at the same time each night and washed off in the morning, 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 night.
Finasteride 0.05%, Minoxidil 5% in Trichosol — 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.
Finasteride warnings
Finasteride affects hormone pathways. Women who are pregnant or may become pregnant must not use this product — it can affect male foetal development. Men with a history of prostate cancer, BPH, or elevated PSA levels need careful assessment before starting. Finasteride lowers PSA levels, which may mask early prostate cancer. Baseline PSA screening may be required. Post-finasteride syndrome (PFS) — persistent sexual dysfunction, mood changes, or other symptoms after stopping — is a rare but recognised concern, even at the lowest available concentration. The prescriber will discuss this risk 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. Systemic absorption is lower with topical use than oral minoxidil, but cardiovascular status will still be reviewed.
A note on concurrent treatments
If you are using other topical hair loss agents alongside this solution, 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 Trichosol base 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 mood or sexual function concerns — will be reviewed during consultation.
Finasteride 0.05%, Minoxidil 5% in Trichosol — Side effects
Common side effects
Common side effects may include scalp irritation, dryness, redness, itching, flaking, or temporary shedding early in treatment. The Trichosol base reduces the likelihood of alcohol and propylene glycol-related dryness and stinging, but it does not eliminate the possibility of local reactions entirely. Early shedding is common when starting minoxidil — it occurs as follicles shift through the hair cycle and usually settles within a few months.
Finasteride-related effects
Finasteride 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 but have been reported. Mood changes, depression, or anxiety have also been documented. Post-finasteride syndrome remains a recognised concern even at the lowest available concentration. 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. 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.
Finasteride 0.05%, Minoxidil 5% in Trichosol — Drug interactions
Why interactions matter with this formula
Both active ingredients carry interaction considerations. Thorough review before starting is essential.
Finasteride interactions
Finasteride is metabolised via the CYP3A4 pathway. Strong CYP3A4 inhibitors may increase finasteride levels; enzyme inducers may reduce them. Topical absorption is lower than oral finasteride, but 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. All current products should be disclosed during consultation.
Finasteride 0.05%, Minoxidil 5% in Trichosol — 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 Trichosol base makes consistent nightly application more comfortable — and comfort supports the consistency that treatment outcomes depend 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 — it contains finasteride, which is contraindicated in pregnancy. Suitability is always assessed individually.
Why does this formula contain two ingredients rather than three?
Some patients need finasteride and minoxidil together without tretinoin at this stage — whether because starting cautiously at the lowest finasteride concentration is the priority, because the prescriber wants to assess response 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 finasteride concentration 0.05%?
0.05% is the lowest available compounded finasteride concentration. The prescriber selects it when clinical assessment — and where used, TrichoTest results — indicates that a cautious starting approach is appropriate, whether because the patient is new to finasteride, has a lower anti-androgen requirement, or the most conservative available approach is clinically indicated. Starting at 0.05% is not starting weak. It is the right option for the right patient.
Why is this formula in Trichosol?
Standard topical solutions contain alcohol and propylene glycol — both of which can cause stinging, dryness, and scalp irritation. Trichosol removes both entirely. For patients who have experienced these reactions with standard products, it can make daily treatment significantly more comfortable — and comfort drives the consistency that good outcomes depend on.
How is finasteride different from dutasteride?
Both are 5-alpha reductase inhibitors that reduce DHT. Finasteride selectively blocks type 2 5-alpha reductase. Dutasteride blocks both type 1 and type 2. 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 the finasteride concentration be increased 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 a higher finasteride concentration, or additional ingredients such as tretinoin, would be beneficial, 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% finasteride in a Trichosol base does not exist in any standard licensed product — compounding is what makes it possible.
Can I use it if standard hair loss products have irritated my scalp?
Quite possibly. The absence of propylene glycol and alcohol removes two of the most common causes of scalp irritation. Suitability still needs to be assessed by a prescriber, but for patients with reactive scalps this Trichosol formulation is often a more comfortable and sustainable option.
How can TrichoTest help with this treatment?
TrichoTest analyses 26 genetic markers across nine key pathways. It helps the prescriber identify whether finasteride is the most appropriate anti-androgen, whether 0.05% is the right starting 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 — 1ml applied to the scalp at night using the dropper bottle.
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. 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 Trichosol better than liquid or foam for this formula?
It depends on your scalp and your previous experience with topical treatments. Trichosol is often the most appropriate choice for patients who have reacted to standard bases or who want a more comfortable daily experience — particularly relevant when starting finasteride for the first time. The prescriber can help you decide.
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. 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, but cardiovascular status is always reviewed before prescribing.
What if I have had problems with finasteride before?
Disclose this during consultation. Any previous adverse effects from finasteride — including post-finasteride syndrome — are essential information for the prescriber to assess your suitability safely.
