learn Spironolactone
powerful topical and oral anti-androgen used mostly by women
- How does spironolactone help reduce hair loss when used in topical or oral treatments? Studies report that spironolactone slows androgen-driven follicle miniaturisation by blocking androgen receptors, with most evidence in women and mostly alongside minoxidil; it is a prescription drug and its use for hair loss is off-label.
- Is spironolactone better for hair regrowth as a pill or as a scalp solution? Oral spironolactone has the stronger published evidence for hair regrowth; topical versions cause fewer systemic side effects but have been studied far less, and no trial has compared the two head to head.
- Who can safely use spironolactone for hair thinning and androgen-related hair loss? Women with androgen-related hair loss can safely use spironolactone under medical supervision.
