This study found that spironolactone significantly reduced hair growth in hirsute women, with noticeable effects in 3-5 months, and decreased serum testosterone levels in all participants.
Spironolactone and finasteride are not recommended for women planning pregnancy due to birth defect risks. Both need to be stopped months before conception, and finasteride is generally not advised for women.
Spironolactone can remain effective for a long time in treating androgenetic alopecia, but it may not completely stop hair loss. Hair loss treatments like spironolactone, finasteride, and dutasteride slow down hair loss rather than cure it, and their effectiveness can vary based on individual response and the aggressiveness of the condition.
Spironolactone, finasteride, and dutasteride are discussed for hair maintenance, with concerns about testosterone and side effects like gynecomastia. Spironolactone is noted for use in both bodybuilding and hormone therapy, with low doses considered for minimizing side effects.
Spironolactone is more potent and lowers testosterone and DHT, while dutasteride only impacts DHT. For female hair loss, checking hormones and considering treatments like oral minoxidil, spironolactone, or topical minoxidil is recommended.
