What medication is known for its use as an androgen suppressor, but does not affect existing hair?

1. Spironolactone (Aldactone)

2. Minoxidil

3. Finasteride

4. Clindamycin

The correct answer is: Spironolactone (Aldactone)

Spironolactone is recognized for its function as an androgen suppressor. It works by blocking the action of androgens, which are hormones that can contribute to hair loss in certain individuals, particularly women experiencing conditions like polycystic ovary syndrome (PCOS) or androgenetic alopecia. Spironolactone does not promote hair growth of existing hair follicles; instead, it primarily prevents further hair loss by addressing hormonal imbalances. This makes it particularly useful for those who want to manage hair loss linked to androgen sensitivity. In contrast, Minoxidil is a topical solution that stimulates hair follicles and is primarily used to promote the growth of new hair rather than suppressing androgen levels. Finasteride is another androgen suppressor, but it specifically inhibits the enzyme that converts testosterone into dihydrotestosterone (DHT), affecting existing hair follicles. Clindamycin is an antibiotic and does not play a role in hair loss or hair growth.
