Search for hair loss treatments and you will find an industry built on hope: serums, supplements, laser combs, subscription boxes. Some of it works, much of it does not, and almost none of it is explained honestly for women. This page compares every treatment for female hair loss we actually use — and a few we deliberately avoid — so you can see the whole landscape in one place.
Hair GP is a doctor-led London clinic dedicated to women’s hair loss. Because Dr Amy Vowler is a GMC-registered doctor, the full range of evidence-based options is on the table — including prescription treatments a trichologist or online shop cannot provide. Just as importantly, treatment starts with a diagnosis, because the right treatment depends entirely on why your hair is thinning.
- – There is no single best treatment — the right option depends on the cause, which is why diagnosis comes first
- – Minoxidil (topical or oral) has the strongest evidence for female pattern thinning
- – Anti-androgens such as spironolactone or finasteride are prescription options used off-label where androgen influence is prominent
- – Correcting iron, thyroid or vitamin D problems is often the highest-value step when a deficiency is found
- – In-clinic options like PRP/PRF and polynucleotides can complement, not replace, medical treatment
Why there is no single best treatment
Female pattern hair loss, telogen effluvium, iron deficiency, thyroid dysfunction, postpartum shedding and hormonal transitions can all look similar in the mirror — and each responds to different treatment. Starting minoxidil for what is actually an iron problem wastes months. That is why every treatment plan at Hair GP begins with a blood work-up (you can also bring your blood tests you have already had done instead) and scalp examination, not a product recommendation.

Prescription treatments: minoxidil for women and anti-androgens
Topical minoxidil is the best-evidenced first-line female pattern hair loss treatment, available over the counter at 2% and 5%. It can also be compounded personally for you on prescription by Dr Amy. Low-dose oral minoxidil has become a widely used alternative where the topical is impractical or poorly tolerated — it is prescription-only and needs medical oversight.
Where androgen influence is prominent, anti-androgen treatment can be added: spironolactone, finasteride or dutasteride, each used off-label in women. These are genuinely effective for the right patient — and unsuitable for others, including anyone pregnant, breastfeeding or planning pregnancy, which is exactly why they belong in a doctor’s hands rather than an online checkout.
What Patients Say
In-clinic treatments
PRP/PRF therapy uses growth factors from your own blood to stimulate follicles; the evidence base is growing and it pairs well with medical treatment. Polynucleotides are a newer regenerative injectable. Low-level light therapy is a gentle adjunct with modest but real evidence. None of these replaces treating the underlying cause — we are honest about that before you spend anything.
Real Results from Real Patients

*Results may vary. Individual results depend on various factors including the type and extent of hair loss, treatment adherence, and individual response to therapy.
What about natural remedies and supplements?
If a blood test finds low ferritin or vitamin D, correcting it properly is not alternative medicine — it is often the single most effective thing we do. Beyond that, the honest picture is thinner: rosemary oil has one small favourable study against 2% minoxidil (which isnt best practice 5% is), saw palmetto is a weak natural anti-androgen, and most “hair vitamins” simply are not needed if your levels are normal. We would rather tell you that than sell you a subscription.
How we choose the right treatment with you
A fifty-minute consultation with Dr Amy covers your history, a magnified scalp examination and the blood tests (only if needed) that matter. You leave with a diagnosis and a written plan that fits your health, your priorities and your budget — pricing is published openly here. Where prescriptions are appropriate, we issue them directly. And we are honest about timescales: meaningful hair regrowth in women takes three to six months of consistent treatment, which is why every plan comes with review photographs rather than promises.
How treatments combine — and what order things happen in
The comparison table above reads as a menu, but real treatment is a sequence. First the diagnosis, because everything downstream depends on it. Then the foundation: correct any deficiency and treat any medical driver — this is unglamorous and does the most work. Then the follicle stimulants — minoxidil in whichever form suits your life — usually alone for the first months so we can attribute what improves. Anti-androgens join where the diagnosis says androgens are driving; in-clinic treatments like PRP layer on top for women who want to compound their gains, never as a substitute underneath. Most women end up on two, occasionally three, well-chosen things — not seven mediocre ones. And every addition gets a review date and a photograph, because a stack you cannot attribute is a subscription, not a plan.
One honest note on expectations: the first visible change is usually less shedding (weeks six to twelve), then fine regrowth at the parting (months three to six), then thickness (six to twelve). Anything promising faster is selling you something this page just taught you to see through.

The genuinely honest answer is that it depends on the cause. For female pattern hair loss, minoxidil has the strongest evidence, sometimes combined with an anti-androgen such as spironolactone. For shedding driven by iron deficiency or thyroid dysfunction, correcting the underlying problem matters more than any hair product. This is why we diagnose before we treat.
Sometimes. If your hair loss is driven by a correctable factor — low ferritin, thyroid dysfunction, a temporary shedding episode after illness or weight change — treating that cause can be enough. Established pattern hair loss usually does need active treatment to reverse miniaturisation, and the earlier it starts, the more there is to recover.
Minoxidil is usually first-line because it has the strongest evidence and works regardless of the degree of androgen involvement. Spironolactone is considered where there are signs of androgen influence, or added when minoxidil alone is not enough. The combination is common in practice — but the sequencing is a clinical decision made after examination and blood work, not a rule of thumb.
Minoxidil, spironolactone, finasteride and dutasteride are all unsuitable during pregnancy and breastfeeding. That does not mean nothing can be done — correcting deficiencies, planning treatment for after weaning, and gentle supportive measures are all reasonable. If this is your situation, say so when you book and we will plan around it safely.
Hair works in slow cycles. Shedding typically settles first, within two to three months; visible regrowth and thickening usually take four to six months, with the full picture at nine to twelve. We review progress with photographs at set intervals so changes you cannot see day-to-day are measured objectively.
If you have a measured deficiency, replacing it works — that is not really a supplement question but a medical one. If your levels are normal, the evidence for most commercial hair supplements is weak, and a few (notably high-dose selenium and vitamin A) can cause hair loss in excess. We will tell you plainly which, if any, are worth your money.
Our consultation and treatment prices are published openly on our pricing page — no packages revealed only in the room, and no subscriptions. Many effective options, such as topical minoxidil, are inexpensive; where we recommend in-clinic treatments we will explain the costs and the expected benefit before you commit to anything.
