What is Finasteride 0.2% topical hair loss liquid?
This compounded topical hair loss liquid contains finasteride 0.2% in a traditional alcohol and propylene glycol base. It is designed for adults with pattern hair loss who need the strongest available compounded finasteride concentration — particularly those whose clinical profile indicates that a high anti-androgen finasteride approach is required, or those who want that concentration delivered efficiently via a precise spray applicator. The aim is straightforward: apply maximum finasteride anti-androgen activity to the hair loss pathway at the highest available concentration, 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 0.2% — the highest available compounded concentration
- May suit people with androgenetic alopecia who need the strongest available finasteride approach in a direct, efficient format
- 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 products that are not strong enough, or not matched to their biology, see little result, and quietly give up — not because treatment cannot work, but because they were never on the right treatment at the right strength to begin with.
A formula for people who need the strongest finasteride approach delivered directly
This liquid is aimed at people who need the highest available compounded finasteride concentration — and who want it delivered in a traditional spray format that absorbs efficiently and applies with precision. It is particularly relevant for those whose prescriber has identified 0.2% as the most appropriate finasteride concentration, those whose TrichoTest results indicate a high anti-androgen requirement that finasteride is best placed to address, and those who have stepped up from a lower-strength formula under clinical guidance.
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 reflects your clinical profile 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 at the highest available finasteride concentration, accurate application night after night is what gives treatment the best possible conditions to work.
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, efficient format that delivers maximum finasteride anti-androgen activity where it is needed.
Adherence is everything
A treatment only works if you apply it consistently. At the highest available finasteride concentration, the stakes of skipping nights are significant. If six precise sprays at the same time each evening is a routine you can maintain without difficulty, the liquid format has a clear practical advantage — and that advantage builds over months of sustained, consistent use.
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 highest available finasteride concentration 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 the most direct available route to the follicles at the strongest available compounded finasteride strength.
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 0.2% finasteride — does not exist in any standard licensed product. Others come to compounding after finding that lower-concentration standard products have not delivered adequate results, and require a stronger, more clinically considered approach. Others have stepped up through the Gro range under prescriber guidance and need the highest available compounded finasteride strength in the most efficient delivery format available.
The 0.2% 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. Compounding makes it possible to prescribe 0.2% finasteride alone — the highest 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 a combination formula. For some, applying the strongest available finasteride concentration as a focused single-ingredient treatment is the most clinically appropriate approach. It may also reflect TrichoTest findings that indicate finasteride at this specific concentration — rather than dutasteride — is the best-matched anti-androgen approach for the individual’s genetic profile and treatment history.
If additional ingredients are indicated, 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 0.2% finasteride concentration
The 0.2% finasteride concentration is one area where TrichoTest is particularly valuable. Some patients have genetic profiles that suggest a high anti-androgen requirement — and that finasteride, specifically, is the most appropriate anti-androgen for their biology. TrichoTest can identify both the right active ingredient and the right concentration before treatment begins, allowing the prescriber to select the highest available finasteride strength immediately rather than stepping up gradually over months.
How the TrichoTest informs this formula
If TrichoTest identifies a high anti-androgen requirement and indicates that finasteride is the most appropriate active ingredient, the prescriber may determine that finasteride 0.2% alone is the most clinically appropriate starting point — before deciding whether additional ingredients 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 the highest available finasteride concentration in 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 0.2% topical hair loss liquid — Active ingredient
Finasteride 0.2%
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 0.2%, this is the highest available compounded finasteride concentration. It reflects a clinical decision that the strongest available finasteride approach is the most appropriate choice for this individual — not a default escalation, but a considered choice based on their profile, history, TrichoTest results where used, 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 scalp absorption and helping the highest available finasteride concentration reach the follicles efficiently. The spray applicator ensures a precise, consistent dose with every application. For patients who tolerate this base well, it offers the most direct available route to the follicles at the strongest available compounded finasteride strength.
What is the Finasteride 0.2% 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 their clinical profile indicates that the highest available finasteride concentration is required — and they want it delivered in a precise, efficient liquid spray format. Others arrive because their TrichoTest results demonstrate a high anti-androgen requirement, and finasteride at 0.2% is the most clinically appropriate concentration and active ingredient from the outset. Others have stepped up from a lower-strength formula under prescriber guidance after finding that a more cautious starting point did not deliver adequate results. In all cases, a compounded single-ingredient liquid at 0.2% finasteride offers a more clinically targeted path than anything available off the shelf.
How does the Finasteride 0.2% 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. For patients whose TrichoTest results or clinical profile indicate that finasteride is the most appropriate anti-androgen — rather than dutasteride — this formula delivers it at the highest available compounded concentration with the precision of a spray applicator and the efficiency of a well-established liquid base.
At 0.2%, the concentration reflects a clinical judgment that the strongest available finasteride approach is the right one for this individual. It is prescribed because clinical assessment and, where used, TrichoTest results have indicated that this level of anti-androgen activity is the best match for this patient’s profile.
Think of finasteride as turning down the hormonal signal as far as the compounded format allows — reducing the DHT-driven pressure that causes follicles to miniaturise over time.
How do you use the Finasteride 0.2% 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. At the highest available finasteride concentration, delivering the right amount to the right place every night is not a small consideration.
The right concentration for you
Because this is a compounded medicine, the prescriber selects the finasteride concentration based on your individual clinical profile. At 0.2%, this formula uses the highest available compounded finasteride strength. It may be the right starting point for patients whose TrichoTest results or clinical profile indicates a high anti-androgen requirement for finasteride specifically, or the right progression for those who have stepped up from a lower concentration under prescriber guidance.
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 0.2% 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 at this concentration within the Gro range 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 0.2% 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 highest 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 — and at this concentration, thorough clinical assessment is particularly important. A full medical history — including cardiovascular status, prostate health, previous medication reactions, and mood or sexual function concerns — will be reviewed during consultation.
Finasteride 0.2% 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 0.2% 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 0.2% 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 0.2% 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 at the highest available finasteride concentration, consistency is the single most important factor in giving treatment a fair chance.
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, applying the highest available finasteride concentration as a focused single-ingredient treatment is the most clinically appropriate approach — whether because of their TrichoTest profile, their treatment history, or a clinical decision to concentrate anti-androgen activity before considering additional ingredients. A single-ingredient liquid is not a lesser option. It is a considered one.
Why is the finasteride concentration 0.2%?
0.2% is the highest available compounded finasteride concentration. The prescriber selects it when clinical assessment indicates this is the most appropriate starting or ongoing strength — whether because TrichoTest results demonstrate a high anti-androgen requirement for finasteride specifically, because the patient has stepped up from a lower concentration, or because their clinical profile indicates the strongest available approach is right from the outset. It is not a default escalation. 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. At the highest available finasteride concentration, this measured delivery means the right amount reaches the right area every night without estimating.
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 0.2% 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, 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 0.2% — without alcohol or propylene glycol — is available at the same concentration and 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 at 0.2% finasteride within the Gro range 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 0.2% 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 at 0.2% finasteride 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. At the highest available finasteride concentration, using a format you can apply every night without difficulty matters most. 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.
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.
