The two foundations: finasteride and minoxidil
Finasteride (a prescription tablet) reduces the hormone signal that miniaturizes follicles in androgenetic alopecia. In long-term studies it stabilizes loss in the large majority of men and often regains some density. It requires a doctor's prescription and periodic follow-up because of rare sexual side effects.
Topical minoxidil (a solution or foam applied to the scalp) works independently of hormones: it prolongs the growth phase and is approved for both men and women. Expect visible results after 4–6 months of consistent twice-daily use; early increased shedding in the first weeks is a known, temporary effect.
Adjunct therapies: PRP and laser
Platelet-rich plasma (PRP) injections use growth factors from your own blood to stimulate follicles. Study results are mixed but increasingly positive for androgenetic alopecia, typically as a complement to — not a replacement for — the two foundations above.
Low-level laser therapy (LLLT) caps and combs have FDA clearance for safety and show modest density gains in some trials. They are unobtrusive, drug-free complements, not stand-alone cures.
What to be skeptical about
Be wary of 'miracle' supplements, exotic serums and any clinic promising regrowth without medical therapy or surgery. Biotin helps only where a genuine deficiency exists; most other marketed supplements lack human evidence for hair growth.
Also treat 'stem cell' and 'exosome' injections cautiously: promising research exists, but regulatory approval and standardized protocols are still missing in most countries. Ask for published data before paying premium prices.
Measure, don't guess
Whatever treatment you and your dermatologist choose, judge it on standardized measurements at 6 and 12 months — not on how your hair looks in a bathroom mirror after a bad night.
HairCraft was built for exactly this: five photos from fixed angles, AI-powered Norwood classification and regional density scores, and a timeline that shows whether your routine is actually working. Data first, decisions second — and always with a medical professional.
