Before: what the trials started with
Both trials enrolled adults aged 18 to 49 with pattern hair loss, androgenetic alopecia in men and female pattern hair loss in women, and measured a fixed target area of scalp at baseline: the count of non-vellus hairs, the terminal hairs that give coverage, plus patient and investigator ratings of hair growth and scalp coverage. That is the “before” that matters. A photo cannot tell you the hair count; the trials did.
After 48 weeks in men: 5% vs 2% vs placebo
The men’s trial randomized 393 participants to 5% solution, 2% solution or placebo, applied twice daily. After 48 weeks, 5% minoxidil was significantly superior to 2% and to placebo on the change from baseline in non-vellus hair count, on the patient’s rating of scalp coverage and treatment benefit, and on the investigator’s rating of coverage. The authors put the magnitude at 45% more hair regrowth on 5% than on 2% at week 48. The hair-count data also showed the response arriving earlier on 5% than on 2%. The cost of the stronger concentration was more itching and local irritation, and the trial found no evidence of systemic effects at either strength.
After 48 weeks in women: 5% vs 2% vs placebo
The women’s trial randomized 381 participants the same way. After 48 weeks, 5% minoxidil was superior to placebo on all three primary measures: non-vellus hair count, patient assessment and investigator assessment of hair growth and scalp coverage. The 2% solution beat placebo on hair count and on the investigator’s assessment, but the patients’ own assessment of growth on 2% was not significantly different from placebo. Patients rated the treatment benefit of 5% above 2%. The trade in women was more itching, irritation and hypertrichosis, unwanted hair growth outside the scalp, on 5%. Both strengths were well tolerated without systemic adverse effects.
Foam once a day vs solution twice a day
A 24-week trial in 113 women compared 5% foam applied once daily with 2% solution applied twice daily. The foam was non-inferior on target-area hair count and hair width, with lower rates of local intolerance, especially itching and dandruff, and better agreement that it did not interfere with styling. That trial was single-blind because the two products look and feel different, which is a limitation to read alongside its result.
The timeline
Both 48-week trials report their endpoints at week 48, and the men’s trial notes an earlier response on 5% than on 2%. Clinicians commonly warn about a temporary increase in shedding in the first weeks of minoxidil, which the trials did not measure as an endpoint. Read the timeline the way the trials did: judge coverage at several months, not at several weeks, and count on the treatment continuing. Pattern hair loss is ongoing, so minoxidil is maintenance; if you stop, the benefit typically fades over the following months.
Oral minoxidil, briefly
Minoxidil taken as a tablet is prescribed off-label for hair loss at low doses and is the subject of a 2021 review of efficacy and safety. It is a prescription decision with its own side-effect profile, including hypertrichosis, and it is not the FDA-approved topical product. A clinician decides whether it is appropriate; this page’s numbers are from the topical trials. The FDA-approved hair loss treatments guide covers where each option stands.
How to get minoxidil online
Topical minoxidil is FDA-approved and sold over the counter, so the reason to see a clinician is the plan around it: whether finasteride belongs alongside it in men, whether a compounded combination makes sense, and what to expect. At PepScribe the online visit is free. A US-licensed clinician reviews your history, and if prescribed, you receive a daily capsule combining finasteride, minoxidil and biotin, compounded in the USA by a licensed 503A pharmacy, from $29/mo with the medication, clinician care and shipping included. The combined capsule is not FDA-approved as a combination product. PepScribe makes no regrowth guarantees; the clinician sets expectations from the evidence above. The finasteride guide and the recommended hair loss treatment guide cover the other half of the plan, and the hair loss treatment page describes what PepScribe offers.
Frequently asked questions
What does minoxidil before and after look like in the trials?
More non-vellus hairs in a measured scalp area and better scalp-coverage ratings at 48 weeks: 5% beat 2% and placebo in 393 men, and beat placebo on every primary measure in 381 women. The trials counted hairs; they did not publish photos as evidence.
How long does minoxidil take to work?
The trials measured their results at 48 weeks, with an earlier response on 5% than on 2% in men. Judge it over months. A temporary increase in shedding in the first weeks is commonly reported in practice.
Is 5% minoxidil better than 2%?
In the men's trial, 5% produced 45% more hair regrowth than 2% at week 48 and an earlier response, at the cost of more itching and irritation. In women, 5% beat placebo on every primary measure where 2% did not, with more hypertrichosis.
Does minoxidil work for women?
In the 48-week trial of 381 women, 5% topical minoxidil was superior to placebo on hair count and on patient and investigator assessments of growth and coverage.
What happens if I stop minoxidil?
Pattern hair loss continues, so the benefit typically fades over the following months. Minoxidil is maintenance therapy.
Is minoxidil FDA-approved?
Topical minoxidil is FDA-approved for hair loss. Oral minoxidil for hair loss is off-label. A 503A-compounded combination of finasteride and minoxidil is not FDA-approved as a combination product.
