learn Follistatin

How does follistatin compare to finasteride or dutasteride for treating androgenic alopecia? Finasteride and dutasteride are prescription drugs with large controlled trials showing they lower DHT and slow androgenic hair loss, at the cost of documented hormonal side effects; follistatin targets a different, regenerative pathway but has only one small phase 1 human trial behind it, so it is experimental with unknown safety rather than a comparable alternative.

learn Metformin

diabetes drug with anti-inflammatory, immunomodulatory, and insulin-sensitizing properties

learn Thymosin Beta 4

learn Stem Cell Factor

learn Overview

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Lavender

Is lavender effective for hormonal hair loss or just stress? Lavender may help with stress-related hair loss but has limited evidence for hormonal hair loss.

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

learn Baicapil

Losing hair from hormonal imbalance? Baicapil might block DHT without messing with your hormones. No published study shows that Baicapil blocks DHT — the only data on the ingredient itself is the manufacturer's own unpublished dossier, and the baicalin research behind the claim is cancer cell-line work in which the effect was explicitly independent of the androgen receptor.

learn Adenosine

Adenosine : Can it help if my hair loss is due to a hormonal imbalance like PCOS or DHT? Adenosine may help improve hair growth affected by hormonal imbalances like PCOS or DHT.
