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.
- How long does it take to see results from spironolactone hair loss products? Trials of oral spironolactone for female pattern hair loss assess results at about six months, with most reporting reduced shedding before any regrowth and meaningful change, when it happens, at six to twelve months; it is a prescription drug used off-label for hair loss.
