How to Stop Hair Loss
The proven treatments that actually work, for men, beards, and women.
Medically reviewed by Dr Ahmad Moussa · GPhC registered UK pharmacy partner · Free Prescription & Delivery
Finasteride and dutasteride are the only medications proven to stop pattern hair loss. Minoxidil, microneedling and topical anti-androgens build on that to encourage regrowth. Cutting through the noise around hair loss products is half the battle; see our truth behind hair loss treatments for a brief reality check, and our crown-loss-specific guide on saving your crowning glory if the thinning is concentrated on the top.
Finasteride 1mg, the first-line oral treatment
Finasteride 1mg is MHRA-licensed in the UK for the treatment of male pattern hair loss (the original brand is Propecia, generics are now widely available). It blocks the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is the hormone that shrinks scalp follicles in men with pattern hair loss. Reducing scalp DHT by around 60% stops the loss and often allows regrowth.
For the full mechanism, dosing, and side-effect profile, see our complete finasteride guide and our long-term safety review at how safe is finasteride.
- What it does: stops loss, often produces regrowth over 6 to 12 months.
- Who it suits: adult men with mild to advanced pattern hair loss.
- Side effects: sexual side effects in a small minority, usually resolving on discontinuation. See the linked guides above.
- Cost: from around £10 a month.
FINASOL-M, topical finasteride with minoxidil
FINASOL is our custom compounded topical finasteride solution made in our TrichoSol base (low alcohol, propylene glycol-free). FINASOL-M is the same solution combined with minoxidil 2% so you get both actives in a single daily application.
Topical finasteride produces substantially lower systemic DHT reduction than the oral tablet, which is why it is the popular choice for men who experienced side effects on oral finasteride or want to reduce that risk. See the published evidence we summarise in topical finasteride systemic absorption and the strength comparison in our topical finasteride strength guide.
Results timeline: initial regrowth at 3 to 4 months, near-full result at 12 months. Gains are maintained only while you continue using it.
Topical minoxidil, the gold-standard follicle stimulant
Topical minoxidil is a vasodilator that improves blood flow to the scalp and extends the growth (anagen) phase of the hair cycle. It is available over the counter in the UK as Regaine, which is MHRA-licensed for the treatment of male pattern hair loss at 5% strength (and at 2% strength for women). Our pharmacy also compounds higher strengths to prescription.
Minoxidil is most effective when paired with a DHT blocker (finasteride or dutasteride) because the two work on different parts of the problem: minoxidil stimulates the follicles, finasteride protects them from further shrinkage. For deeper context see the complete minoxidil guide and our advice on how to spot fake Kirkland minoxidil if you have been buying from US importers.
How to use: 1ml twice daily on a clean, dry scalp. Wait 4 hours before washing. Visible improvement at 4 months in most users.
Oral minoxidil, prescription tablet alternative
Oral minoxidil is MHRA-licensed in the UK only as Loniten for severe hypertension; its low-dose use for hair loss is off-label but well established in clinical practice and is the fastest-growing hair loss prescription in UK clinics. At hair-loss doses (0.25mg to 2.5mg daily) it has become a popular alternative for patients who find topical minoxidil too messy or too irritating.
Most prescribers start patients at 1.25mg daily for two weeks, then increase to 2.5mg or 5mg if tolerated. Full effect is seen at 6 to 12 months. For dosing nuances and who it suits see our oral minoxidil article.
Dutasteride 0.5mg, when finasteride is not enough
Dutasteride (originally Avodart) is MHRA-licensed in the UK for benign prostatic hyperplasia; its use for hair loss is off-label but well established in clinical practice worldwide. It blocks both Type I and Type II 5-alpha reductase, cutting scalp DHT by around 90% (finasteride blocks Type II only and cuts DHT by around 60%). In clinical comparisons it is more effective than finasteride, especially for men who have plateaued on the lower-strength alternative.
The trade-off is that the stronger DHT suppression carries a marginally higher side-effect profile. Most prescribers move patients to dutasteride after a structured 6 to 12 months on finasteride if response has stalled. See our full dutasteride guide and the side-by-side at finasteride vs dutasteride.
DUTASOL, topical dutasteride with minoxidil
DUTASOL is our custom compounded topical dutasteride formula in the same TrichoSol base. The standard version combines dutasteride 0.025% to 0.1% with minoxidil 10%, delivering both DHT blockade and follicle stimulation in one daily application.
DUTASOL is intended for men with moderate to advanced pattern hair loss who want the strength of dutasteride without the systemic exposure of the oral tablet. See the full product story at our DUTASOL guide.
Minocream 15%, for non-responders to standard minoxidil
A surprisingly high percentage of patients do not respond well to standard 5% minoxidil solutions. Minocream is a 15% minoxidil formulation in a cream base, more suitable for sensitive scalps that find alcohol-based liquids irritating.
Significant results typically take 6 months of continuous use. Minoxidil works only while you use it, so the result is maintained as long as you continue.
Microneedling, boost the absorption of every topical
Microneedling with a derma roller or stamp creates microscopic channels in the scalp that increase topical absorption and trigger the body's growth-factor response. Several published studies show it materially improves the results of topical minoxidil.
Use a derma stamp 1 to 2 times per week (not daily). Apply minoxidil within 30 minutes of stamping for best absorption. Keep your roller clean: see our step-by-step derma roller cleaning guide.
Ketoconazole shampoo, a supporting treatment
2% ketoconazole shampoo (Nizoral, Dandrazol, Ketopine) was developed as an antifungal shampoo for seborrheic dermatitis. Several studies suggest it has a mild secondary effect on hair loss when used alongside finasteride and minoxidil, by reducing scalp inflammation and possibly blocking some DHT activity at the follicle.
It is not a stand-alone hair loss treatment. Use it 2 times per week as part of a wider protocol. See the evidence review at should you use ketoconazole shampoo for hair loss.
Pharma Hermetic, non-prescription option
Pharma Hermetic is a non-prescription topical product range based on a botanical nutrient complex. It is positioned as an alternative for patients who cannot take finasteride or want to try a natural-derived option first. See the Pharma Hermetic guide for the full ingredient breakdown and what to realistically expect.

Frequently asked questions
What actually stops hair loss?+
For pattern hair loss (the cause in 95 percent of men and most women over 40), the only treatments with strong clinical evidence are 5 alpha reductase inhibitors (finasteride, dutasteride), minoxidil (topical and low dose oral), and for women, spironolactone. Hair transplants address areas that are already bald but do not stop ongoing loss elsewhere. Anything else (shampoos, supplements, low level laser caps) has weak or mixed evidence.
Can hair loss be reversed?+
Partially. Treatments like finasteride and minoxidil can regrow hair where follicles are still alive (miniaturised but functional) and prevent further loss. Areas that are fully bald (no visible follicles) cannot be regrown medically; that needs a hair transplant. Earlier treatment generally produces better results because more follicles are still alive to respond.
What is the most effective treatment for hair loss?+
For men, the combination of oral finasteride plus topical minoxidil has the strongest evidence and is often called the "big 3" alongside microneedling. For more advanced loss, dutasteride is more potent than finasteride. For women, topical minoxidil (often combined with spironolactone for hormonal cases) is first line. Topical finasteride (FINASOL) is a newer option for men who want similar results with reduced systemic exposure.
How long before I see results?+
Most people notice reduced shedding by 3 months, visible regrowth between 6 and 12 months, and full effect by 12 to 18 months. The first month often brings a temporary increase in shedding as the hair cycle resets; this is normal and a sign the treatment is working. Stopping treatment reverses gains over 6 to 12 months.
Is there a permanent cure for hair loss?+
No. Pattern hair loss is genetic and chronic, so treatment is lifelong. Finasteride, dutasteride, minoxidil and spironolactone manage the condition; they do not cure it. Hair transplants move existing healthy follicles to bald areas but do not prevent ongoing loss elsewhere on the scalp.
Why am I losing so much hair?+
For most adults the cause is androgenetic alopecia (pattern hair loss), driven by genetics and the hormone DHT acting on scalp follicles. Other common causes include telogen effluvium (stress, illness, postnatal), iron or vitamin D deficiency, thyroid problems, and harsh styling. A simple blood test and a 5 minute scalp assessment usually identify the cause. The UK prescriber team reviews this as part of the online questionnaire.
