The treatments that reliably regrow women’s hair are, almost without exception, prescription treatments — and the gap between “bought a product” and “prescribed a medicine” is where most treatment years are lost. A prescription from a doctor who treats women’s hair daily means the right drug for your diagnosis, at a dose chosen for you, with bloods where they’re needed, honest safety counselling, and someone accountable for adjusting course. At Hair GP that doctor is Dr Amy, GMC-registered and prescribing from our London clinic — not a checkout flow with a questionnaire.
This page explains what we prescribe for women, how prescribing actually works here, and how to tell doctor-led treatment from a subscription in a doctor’s costume.
- – The medicines with the strongest evidence for women — oral and topical minoxidil, spironolactone, and 5-alpha-reductase inhibitors where appropriate — are prescription-only or prescription-strength
- – The right prescription follows a diagnosis: the same thinning can need entirely different medicines depending on what examination and bloods show
- – Every prescription comes with monitoring — a review date, photographs, and bloods where the drug requires them
- – Prescriptions are issued at your consultation and repeated without re-consulting each time, with an annual review to confirm the plan still fits
- – Unlike other clinics there is no additional charge for prescriptions, you just pay the pharmacy cost
- – Conception plans change everything: several of these medicines must be stopped before trying — sequencing them is part of the prescription, not an afterthought
What we actually prescribe for women — and when
Four families do most of the work. Low-dose oral minoxidil has become the quiet workhorse of female hair medicine — one small tablet, no scalp routine, dosed and monitored properly. Topical minoxidil (sometimes compounded with other ingredients) at prescription strengths suits women who prefer to treat the scalp directly. Spironolactone earns its place where androgens are driving the pattern — the common thread in PMOS/PCOS and much post-menopausal thinning. And the 5-alpha-reductase inhibitors — finasteride and dutasteride — are options in carefully selected women, almost always post-menopausal, where their evidence is strongest and their constraints manageable. Which of these you should take is not a menu choice: it falls out of the diagnosis, which is why prescribing here starts with examination and if needed bloods, not with a preference.

Prescriptions are issued where clinically appropriate at the £300 consultation; repeat prescriptions then run without re-booking, with an annual review. There is no charge for the prescriptions, you just pay the pharmacy costs.
Why your own GP can’t prescribe these — and Dr Amy can
It surprises many women that the medicines on this page rarely arrive through their own doctor — and that isn’t your GP’s failing; it’s how prescribing works. Medicines like finasteride and spironolactone are prescribed off-label for female hair loss, and doing that safely requires specialist training, experience and specific indemnity insurance that sit outside standard general practice — NHS or private. Dr Amy is a GP with a Special Interest in hair loss: alongside general practice she holds a Postgraduate Certificate in Hair Science and Trichology — specialist training at mini-masters level — and carries the specialist indemnity that covers off-label hair prescribing. That combination is precisely what allows her to prescribe finasteride, spironolactone and the other medicines on this page where a general GP — however good — cannot. For these treatments, seeing a hair-specialised doctor isn’t an upgrade on seeing your GP; it’s the only route.

Why prescription treatment rewards starting early
Pattern hair loss works by miniaturisation: each cycle, affected follicles regrow their hair slightly finer, until eventually a follicle stops producing visible hair at all. The prescriptions above interrupt that slide — but they rescue miniaturising follicles far more reliably than dormant ones. Practically, that means the same medicine started two years earlier buys a visibly different head of hair, and “I’ll try supermarket products for another year first” has a real, biological cost. The diagram below shows both futures of the same follicle.
It also means honest expectations: prescription treatment is judged over months — shedding settles first, regrowth follows, and the result is assessed against photographs at reviews, not against the mirror on a bad morning.
What Patients Say
How prescribing works at Hair GP
You book the fifty-minute consultation. Dr Amy examines your scalp under magnification, takes the history that actually determines drug choice — cycles, contraception, conception plans, blood pressure, medications — and arranges bloods where they change the decision. You leave with a written plan; prescriptions are issued directly where appropriate, with the safety conversation done properly: what to expect in the first weeks (including the temporary shed that panics everyone), what side effects would matter, and which of these medicines must be stopped before trying to conceive. Repeats then run without re-consulting each time; reviews happen against photographs; and when life changes — a pregnancy planned, a menopause arriving, a blood pressure medication added — the prescription changes with it, by message rather than odyssey. That continuity is the difference between being on a medicine and being under treatment.
Not sure your thinning needs prescription treatment at all? The free fifteen-minute call is the honest way to find out before spending anything.
The first twelve weeks on a prescription — what actually happens
Every medicine on this page follows the same opening act, and knowing it in advance is half the treatment. Weeks one to six: nothing visible, and quite possibly a temporary increase in shedding — the notorious “dread shed”, which is the follicle cycle resetting and the single most common reason women abandon a working treatment. We warn you, in writing, so week four doesn’t ambush you. Weeks six to twelve: shedding settles below your baseline; the plughole quietens before the mirror improves. Your part in this phase is boring and decisive — take the medicine, photograph your parting monthly in the same light, and resist daily inspection. When to actually call us: side effects that trouble you (unwanted facial hair, ankle swelling, dizziness), you decide to plan a pregnancy, or a new medication from another doctor — each gets an adjustment, usually by message rather than appointment. What not to do: add three supplements and a new shampoo in month two, because when improvement comes we need to know what earned it.
Repeat prescriptions, reviews, and staying on treatment sensibly
Hair medicine is maintenance medicine — stopping returns you, over months, to the trajectory you left — so the system around repeats matters as much as the first script. Ours is deliberately low-friction: once your dose is settled, repeats are issued without re-booking or re-paying a consultation each time; you message, we prescribe, the pharmacy dispenses. The safeguards sit at sensible intervals instead — photographs at reviews, blood pressure and bloods where your particular medicine warrants them, and an annual review that asks the questions a renewal button never will: is the dose still right, has your health or contraception changed, is anything on the horizon — conception, surgery, menopause — that should reshape the plan? And when a treatment has genuinely underperformed at twelve months, we say so and change course, sometimes towards genetic testing to choose its successor intelligently. Being under treatment should feel like having a doctor — not a subscription that renews whether or not it’s working.

The main evidence-based options are low-dose oral minoxidil, prescription-strength topical minoxidil, spironolactone where androgens are driving the pattern, and — in carefully selected, usually post-menopausal women — finasteride or dutasteride. Which is right depends entirely on the diagnosis: examination under magnification plus targeted blood tests decide the choice, dose and monitoring, which is why we don’t prescribe from questionnaires.
Plenty of websites will sell you one, but we don’t work that way. The examination is where the diagnosis happens — the same thinning can need completely different medicines depending on what the scalp and bloods show — and the drugs themselves deserve proper counselling on blood pressure, conception timing and expectations. At Hair GP prescriptions are issued at an in-clinic consultation; repeats then continue without re-booking each time.
For many women, low-dose oral minoxidil wins on real-world results because it removes the daily scalp routine that quietly defeats topical treatment — and adherence is most of the battle. Topical remains an excellent choice for women who prefer treating the scalp directly or have reasons to avoid a systemic medicine. It’s a genuine clinical decision based on your blood pressure, history and preferences, not a fashion contest.
All real medicines can. Oral minoxidil can cause unwanted facial hair growth and, less commonly, ankle swelling or blood-pressure effects — which is why it’s dosed low and monitored. Spironolactone can affect periods and potassium in some circumstances. Finasteride and dutasteride must not be taken by women who could become pregnant. This is exactly why prescribing belongs with a doctor: the risks are manageable when someone competent is managing them.
Shedding typically settles between weeks six and twelve, fine regrowth appears at the parting around months three to six, and visible thickness builds from six to twelve months — hair grows about a centimetre a month, so every genuine treatment is judged in months. Expect a possible temporary increase in shedding in the first weeks: it’s the cycle resetting, not the treatment failing, and we warn you about it in advance.
You tell us, and the plan changes cleanly. Spironolactone, finasteride and dutasteride are stopped before trying to conceive, and minoxidil is not used in pregnancy or breastfeeding — the sequencing is built into your written plan from day one if conception is on your horizon. Treatment then resumes on the other side; the postpartum chapter is planned rather than improvised. This conversation is a standard part of every consultation with women of childbearing age.
