Hair loss treatment at Hi-Doctor starts with a medical assessment by a licensed doctor who reviews your history and suggests a suitable treatment plan rather than offering a menu of options. If a treatment is not safe for you, the doctor tells you at no cost.

​
One process, every category

A licensed doctor reviews your history and suggests a suitable treatment plan. If a treatment isn’t safe for you, they’ll tell you at no cost.

Weight loss

A medical consultation on your weight goal. Treatment if appropriate.

Sexual health

An absolutely discreet consultation for intimate concerns.

Hair growth

Medical assessment and tailored treatment for hair loss.
Choose what fits — the journey is identical in every category: questionnaire, doctor review, and treatment only where appropriate. See treatment areas for how each questionnaire differs.

​
Treatments a doctor considers

Propecia (finasteride)

A daily tablet, EU-authorised for male pattern hair loss, that lowers DHT. The reviewing doctor sets the dose.

Topical minoxidil

A scalp solution or foam, EU-authorised for pattern hair loss, applied twice daily.

Finasteride for female hair loss

Off-label use in women, with strict pregnancy safeguards. The reviewing doctor sets the dose.

Hair transplant

Why this is surgery, not something a doctor here can prescribe.

How the medicines work

While finasteride and minoxidil have been used for decades, their biological actions at receptor and cellular level are distinct and explain both their efficacy and their limitations.
Finasteride competitively inhibits the type II isoform of steroid 5α-reductase (SRD5A2), the enzyme that converts testosterone into dihydrotestosterone (DHT). The crystal structure of SRD5A2 bound to finasteride reveals a covalent adduct with the NADPH cofactor at the catalytic site, mediated by residues E57 and Y91, which renders the inhibition irreversible (PMID 33110062). In the scalp, DHT binds to androgen receptors on dermal papilla cells, shortening the anagen (growth) phase of the hair cycle and progressively miniaturising terminal hairs into vellus-like hairs (PMID 34157805). By lowering DHT concentrations in the scalp and serum, finasteride reverses this miniaturisation signal.
Minoxidil is a prodrug: it requires sulphation by sulfotransferase SULT1A1 in the outer root sheath of the hair follicle to form the active metabolite minoxidil sulphate (Front Pharmacol 2025;16:1718208). Inter-individual variation in SULT1A1 activity is the main reason some people respond poorly to topical minoxidil. The active metabolite opens ATP-sensitive potassium (K_ATP) channels of the Kir6.1/SUR2B subtype expressed in dermal papilla cells (PMID 18258787), causing membrane hyperpolarisation and vasodilation. Beyond vasodilation, minoxidil upregulates vascular endothelial growth factor (VEGF), promotes nuclear accumulation of β-catenin, and prolongs the anagen phase so that existing hairs grow longer and thicker before shedding.

Common questions

You answer a 4-minute questionnaire about your health and hair-loss pattern. A licensed EU doctor reviews it within 24 hours and, if treatment is appropriate, issues an electronic prescription. If the doctor does not approve treatment, the consultation fee is refunded in full.
A doctor may consider finasteride (a daily tablet that lowers DHT), topical minoxidil (a scalp solution applied twice daily), or a combination of both. In specific cases, oral minoxidil, dutasteride or a personalised compounded formulation may be considered. The choice depends on your pattern of loss, medical history and the EU authorisation status.
Most treatments need 6 to 12 months of consistent use before the effect can be judged. In the first few months, some shedding is normal and means the treatment is active. Visible regrowth is assessed at around 12 months.
Topical minoxidil is authorised for female pattern hair loss. Finasteride is authorised for men only and is contraindicated in women of childbearing potential because it can cause abnormalities in a male foetus. A doctor may consider finasteride or spironolactone off-label in specific cases with strict pregnancy safeguards.
No. Hair transplant is surgery and is not something a doctor here can prescribe. The treatment page covers the medical options a doctor can prescribe after an online consultation.

Hair-growth consultation

Answer the hair-growth questionnaire and a registered doctor reviews it. They decide whether treatment is appropriate, which one, and at what dose — and declining is a normal outcome. See what it costs and how the review works.
