Finasteride 0.05% topical hair loss liquid — Product description
The problem with hair loss
Hair loss is easy to dismiss until it starts affecting you. At first, you may notice thinning at the crown, a wider parting, or a hairline that keeps moving backwards. However, the emotional impact often goes beyond what you see in the mirror. Confidence can drop. Self-consciousness can build. Over time, the feeling that things are getting worse — and that nothing has made a real difference so far — can become part of daily life.
The problem with doing nothing
Pattern hair loss does not pause while you decide what to do next. Instead, follicles continue to miniaturise under the influence of DHT. As a result, delaying treatment can allow hair loss to progress further.
At the same time, many people spend months trying products that do not match their biology or use strengths that do not suit their profile. Then, when results disappoint, they assume treatment does not work. In reality, the problem is often not the treatment itself. More often, it is the wrong treatment, at the wrong concentration, for the wrong person.
Why choose a single-ingredient approach?
Not every patient needs a combination formula from the start. In some cases, patients want to focus treatment entirely on finasteride so they can target the hormonal driver of hair loss directly. In other cases, a prescriber may recommend this formula because a clinical assessment or TrichoTest result shows that finasteride alone, at the lowest available compounded concentration, is the most suitable starting point.
So, a single-ingredient compounded liquid is not a compromise. Instead, it represents a clear clinical choice based on individual need.
Why choose a traditional liquid base?
This liquid format uses alcohol and propylene glycol, which form a well-established base in topical hair loss treatment. These excipients help enhance penetration, so they carry the active ingredient through the scalp barrier efficiently. In addition, clinicians have used this type of base in topical hair loss products for many years.
For patients who tolerate it well, this format offers a direct and practical option that gets on with the job without unnecessary complexity.
A dose you can measure
The spray applicator delivers exactly 1ml across six sprays. That means no estimating and no guesswork. Instead, you can apply the treatment with more control and consistency.
Each spray lands where you direct it, so you can target areas of thinning rather than applying product across the whole scalp. This level of precision matters, especially when you use treatment night after night and want a routine that feels accurate and repeatable.
Why 0.05% finasteride?
This formula contains 0.05% finasteride, which is the lowest available compounded strength. A prescriber selects this concentration when it best fits the patient’s clinical profile, treatment goals, and response pattern.
For some patients, it provides a sensible starting point for compounded finasteride treatment. For others, it reflects a TrichoTest result that suggests a lower anti-androgen requirement. In some cases, it also becomes the right long-term concentration because it matches the patient’s individual response and tolerability.
So, starting at 0.05% does not mean starting weak. It means starting at the concentration that is right for you.
A medically responsible route
At Courier Pharmacy, treatment always starts with a proper clinical assessment. We check suitability carefully before a prescriber makes any decision. If this compounded liquid is prescribed, that decision is based on your scalp, your medical history, and your treatment goals.

What is Finasteride 0.05% topical hair loss liquid?
This compounded topical hair loss liquid contains finasteride 0.05% in a traditional alcohol and propylene glycol base. It is designed for adults with pattern hair loss who want a targeted, single-ingredient approach — particularly those whose clinical profile indicates that finasteride at the lowest available concentration is the most appropriate starting point, or those who want the efficiency of a well-established liquid base with precise, measured delivery via a spray applicator. The aim is straightforward: address the hormonal driver behind hair loss at the most cautious compounded finasteride concentration available, applied accurately and consistently night after night.
Single active ingredient targeting the root hormonal cause of pattern hair loss
Traditional spray liquid format for precise, measured delivery
Finasteride at 0.05% — the lowest available compounded concentration
May suit people with androgenetic alopecia who are new to compounded finasteride or want a careful, direct start
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 want a cautious, direct start
This liquid is aimed at people who want a carefully considered, single-ingredient approach to targeting the hormonal driver of hair loss — at the lowest available compounded concentration, delivered in a traditional format that absorbs efficiently. It is particularly relevant for those new to compounded finasteride treatment, those whose prescriber has identified 0.05% as the most appropriate starting concentration, and those who want the precision of a spray applicator to deliver treatment exactly where it is needed.
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 makes clinical sense and a format that delivers the active ingredient efficiently, night after night.
The traditional liquid advantage
Precise dosing with every application
The spray applicator removes the guesswork entirely. Six sprays deliver exactly 1ml — the standard prescribed dose — every single time. You direct each spray to the areas of thinning. No pooling. No drift. That precision makes consistent, accurate use straightforward and repeatable — which matters particularly when starting at the lowest available concentration where consistent delivery is key.
An established vehicle with a proven track record
Alcohol and propylene glycol are effective penetration enhancers with decades of clinical use in topical hair loss treatment. They carry the active ingredient through the scalp barrier efficiently — making this a direct, no-fuss format that gets on with the job.
Adherence is everything
A treatment only works if you apply it consistently. If six precise sprays at the same time each evening is a routine you can maintain, that practical advantage builds over months — in exactly the way good hair loss treatment should, particularly when starting cautiously at the lowest available concentration.
Why the liquid vehicle matters
The alcohol and propylene glycol base is clinically relevant as well as practically efficient. It acts as an effective penetration enhancer — promoting scalp absorption and helping the active ingredient reach the follicles that need it. The spray applicator ensures a precise, consistent dose with every application. For patients who tolerate this base well, it offers a direct and efficient route to the follicles that need treatment.
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 a compounded liquid because the concentration they need — such as 0.05% finasteride — does not exist in any standard licensed product. Others come to compounding after trying standard options without adequate results, wanting a more clinically considered approach at a precisely tailored concentration. Others want the flexibility to begin with the lowest available finasteride strength and expand their formula as treatment progresses.
The 0.05% finasteride concentration in this formula cannot be obtained from any standard licensed product. It is only possible through compounding — and it is prescribed at this strength because clinical assessment indicates this is the most appropriate starting or ongoing dose for the individual being treated.
Personalised medicine in practice
Hair loss is not identical from one person to the next. The right finasteride concentration for one patient is not the right concentration for another, and the right number of ingredients at one stage of treatment may not be right at another. Compounding makes it possible to prescribe 0.05% finasteride alone — the lowest available compounded strength, in 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 single-ingredient treatment can be the right choice
Not every patient needs to start with a combination formula. For some, a single-ingredient approach at the lowest available concentration is the most clinically appropriate way to begin. It allows the prescriber to assess individual response before expanding the formula. It may also reflect TrichoTest findings that indicate finasteride alone — at this specific concentration — is the best-matched approach for the individual’s genetic profile and treatment history.
If response is good, the formula can be built upon over time. If additional ingredients are indicated from the outset, 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 the 0.05% finasteride concentration
The 0.05% finasteride concentration is one area where TrichoTest is particularly valuable. Some patients have genetic profiles that suggest a lower anti-androgen requirement — meaning 0.05% may be as effective for them as a higher concentration would be for someone else. TrichoTest can identify this before treatment begins, helping the prescriber choose the right starting strength from the outset rather than adjusting after months of treatment.
How the TrichoTest informs this formula
If TrichoTest identifies a lower or cautious response requirement for anti-androgens, the prescriber may determine that finasteride 0.05% alone is the most clinically appropriate starting point — before deciding whether additional ingredients or a higher concentration are indicated.
If the test reveals factors that would make a combination formula more beneficial from the outset — such as poor minoxidil response or low collagen synthesis capacity — the prescriber may recommend a multi-ingredient formula instead, or plan to expand this one 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 liquid 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 formula — at this specific finasteride concentration, in this specific base — 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. Six sprays deliver a precise 1ml dose. This is the formulation described on this page. Chosen by patients who want a direct, proven 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 but want the same active ingredient at the same strength.
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% topical hair loss liquid — Active ingredient
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 available approach is the most appropriate starting strength for this individual — not a lesser option, but a considered choice based on their profile, history, and treatment goals.
Why the liquid vehicle matters
The alcohol and propylene glycol base is clinically relevant as well as practically efficient. It acts as an effective penetration enhancer — promoting absorption and helping the active ingredient reach the follicles efficiently. The spray applicator ensures a precise, consistent dose with every application. For patients who tolerate this base well, it offers a direct and efficient route to the follicles that need treatment.
What is the Finasteride 0.05% topical hair loss liquid 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 they are new to compounded finasteride and want to start with the lowest available concentration in a precise, efficient liquid spray format. Others arrive because their TrichoTest results suggest a lower anti-androgen requirement, making 0.05% the most clinically appropriate starting concentration. Others still come after trying standard options without satisfactory results, wanting a more considered clinical plan at a carefully selected strength. In all cases, a compounded single-ingredient liquid at 0.05% finasteride offers a more purposeful path than anything available off the shelf.
How does the Finasteride 0.05% topical hair loss liquid work?
Pattern hair loss is driven by a hormonal process. Finasteride addresses that process directly.
Finasteride: blocking the hormonal signal
In pattern hair loss, follicles gradually shrink under the influence of DHT. Hairs become finer, shorter, and less visible over time. Left unaddressed, follicles eventually stop producing visible hair altogether.
Finasteride works by blocking type 2 5-alpha reductase — reducing the conversion of testosterone into DHT at the follicle. It is a well-established anti-androgen approach with a long track record in pattern hair loss treatment. For patients whose TrichoTest results or clinical profile indicate that finasteride is the most appropriate anti-androgen — and that the lowest available concentration is the right starting point — this formula delivers it with the precision of a spray applicator and the efficiency of a well-established liquid base.
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.
How do you use the Finasteride 0.05% topical hair loss liquid?
This formulation is a topical liquid and should only be used exactly as prescribed. The usual direction is:
Apply 1ml (6 sprays) at night to the scalp and wash off in the morning.
A dose you can control
Six sprays deliver a consistent, measured 1ml dose every time. You direct each spray precisely to the areas of thinning, then massage gently with your fingertips to distribute evenly. No estimating. No concern about whether you applied too much or too little. No dripping onto skin you did not intend to treat.
The right concentration for you
Because this is a compounded medicine, the prescriber selects the finasteride concentration based on your individual clinical profile. At 0.05%, this formula uses the lowest available compounded finasteride strength. It may be the right starting point for patients who are new to finasteride, those with a lower anti-androgen requirement identified by TrichoTest, or those whose prescriber has determined that the most cautious starting point is the most clinically appropriate approach.
Building a routine that works
Many people find it easiest to apply as part of their evening routine — after a shower, before bed. The liquid works overnight and washes off as part of a normal morning routine. Applied consistently at the same time each night, treatment has the best possible conditions to deliver results.
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% topical hair loss liquid — 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 — including alcohol or propylene glycol.
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. Men with a family history of prostate cancer should discuss this with the prescriber.
A note on concurrent treatments
This formula contains finasteride only. If you are using minoxidil or other topical hair loss agents alongside this liquid, disclose this during consultation. Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. If minoxidil is part of your broader treatment plan, cardiovascular risk and relevant drug interactions will also need to be assessed.
A note on the liquid base
Some patients find alcohol and propylene glycol-based products cause scalp dryness, stinging, or irritation — particularly those with more sensitive skin. If you have previously reacted to products containing these excipients, discuss this with the prescriber before starting. Alternative formats — including the foam and the Trichosol alcohol-free and propylene glycol-free solution — are available within the Gro range at the same concentration and may be more appropriate.
Post-finasteride syndrome
Post-finasteride syndrome (PFS) is a rare but recognised concern linked to finasteride use. It refers to persistent sexual dysfunction, mood changes, or other symptoms that may continue after stopping the medication. Topical finasteride at 0.05% carries lower systemic exposure than oral forms, but the prescriber will discuss this risk during consultation. Any previous adverse effects from finasteride must be disclosed.
Compounded does not mean casual
The traditional liquid format and lowest available finasteride concentration 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, previous medication reactions, and mood or sexual function concerns — will be reviewed during consultation.
Finasteride 0.05% topical hair loss liquid — Side effects
Common side effects
Common side effects may include scalp irritation, dryness, redness, itching, flaking, or temporary shedding early in treatment. The alcohol and propylene glycol base may cause more noticeable dryness or a mild stinging sensation in some patients — particularly in the first few weeks of use. Early shedding can be unsettling, but it occurs as follicles shift through the hair cycle in response to treatment and usually settles with time.
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 with finasteride use, and post-finasteride syndrome remains a recognised concern. The prescriber will discuss this during consultation.
Report mood changes, persistent sexual dysfunction, or any other concerning symptoms promptly.
If the base causes persistent irritation
If scalp dryness or irritation from the alcohol and propylene glycol base becomes a consistent problem, do not push through. Ask for a review. The foam or Trichosol version of finasteride 0.05% may be a more suitable alternative. One of the genuine advantages of compounded treatment is that the format can be adjusted when tolerability becomes an issue — without changing the clinical strength.
When to seek advice
Seek advice if you develop marked irritation, swelling, chest symptoms, dizziness, palpitations, signs of allergy, severe mood changes, or persistent sexual dysfunction.
Finasteride 0.05% topical hair loss liquid — Drug interactions
Why interactions still matter with topical treatment
Even as a single-ingredient formula at the lowest available concentration, finasteride carries interaction considerations. Thorough review before starting remains important.
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.
Other scalp products
Other scalp treatments, harsh exfoliants, or irritating cosmetic products may increase the risk of local reactions — and may compound the drying effect of the alcohol base. Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. All current products should be disclosed during consultation.
Previous finasteride reactions
If you have a history of post-finasteride syndrome or adverse effects from finasteride, disclose this before starting. This information is essential for the prescriber to assess suitability safely.
Finasteride 0.05% topical hair loss liquid — FAQs
How long does it take to see results?
Hair loss treatment needs patience. Most people need several months of regular use before they can judge whether a treatment is helping. The spray applicator makes consistent nightly dosing straightforward — and consistency is the single most important factor in giving treatment a fair chance, particularly when starting at the lowest available concentration.
Is this suitable for both men and women?
It may suit some adults, but the prescriber will assess this carefully. Hormonal considerations and pregnancy risk are especially important. Women who are pregnant or may become pregnant must not use this product.
Why is this a single-ingredient formula?
Not every patient needs a multi-ingredient formula from the outset. For some, finasteride alone at the lowest available concentration is the most clinically appropriate starting point — whether because they are new to finasteride, their TrichoTest profile suggests a lower anti-androgen requirement, or a clinical decision has been made to assess response to a single ingredient before expanding the formula. A single-ingredient liquid is not a lesser option. It is a considered one.
Why is the finasteride concentration 0.05%?
0.05% is the lowest available compounded finasteride concentration. The prescriber selects it when clinical assessment indicates this is the most appropriate starting or ongoing strength — whether because the patient is new to finasteride, TrichoTest results suggest a lower anti-androgen requirement, or a cautious approach is clinically indicated. Starting at 0.05% is not starting weak. It is the right option for the right patient.
How does the spray applicator work?
Six sprays deliver exactly 1ml — the standard prescribed dose. Direct each spray to the areas of thinning, then massage gently with your fingertips to distribute evenly. This measured delivery removes guesswork and makes accurate application straightforward night after night.
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 active ingredient for your individual genetic profile. The prescriber will discuss the most suitable option for your specific clinical situation.
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. It allows the ingredients, concentrations, and format to be tailored specifically to the person being treated. The 0.05% finasteride concentration in this formula does not exist in any standard licensed product — compounding is what makes it possible.
Can I add more ingredients 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 minoxidil, tretinoin, or other ingredients would be beneficial — or that a higher finasteride concentration is appropriate — the prescriber can adjust the formula accordingly. Discuss this during your consultation or at review.
What if the liquid base causes dryness or irritation?
Some patients find alcohol and propylene glycol-based products cause scalp dryness or stinging — particularly at the start. If this becomes a persistent problem, ask for a review. The foam or Trichosol version of finasteride 0.05% — without alcohol or propylene glycol — may be a more suitable alternative.
Can I use it if standard hair loss products have irritated my scalp?
If you have previously reacted to alcohol or propylene glycol-based products, discuss this with the prescriber before starting. A foam or Trichosol alternative within the Gro range at 0.05% finasteride may be more appropriate for your scalp.
How can TrichoTest help with this treatment?
TrichoTest analyses 26 genetic markers linked to hair loss susceptibility and treatment response across nine key pathways. It helps the prescriber decide whether this single-ingredient liquid is right for you — and whether 0.05% finasteride is the appropriate active ingredient and concentration — based on your unique genetics rather than a standard protocol. It can also identify whether additional ingredients are likely to be beneficial, and which nutritional gaps or metabolic factors may be affecting your hair health.
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 (six sprays) to the scalp at night.
What is the difference between liquid, foam, and Trichosol?
Liquid is a traditional spray solution containing alcohol and propylene glycol — efficient absorption, precise spray delivery. 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 liquid better than foam or Trichosol?
It depends on your scalp, your sensitivities, and what you find workable in daily use. The liquid base offers efficient absorption and precise spray delivery. The foam and Trichosol options suit patients who find the liquid base uncomfortable. The prescriber can help you decide which format fits your scalp and your routine 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. Disclose all current treatments during consultation.
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 for this treatment safely.
