Propecia, containing finasteride, is a prescription medication primarily used to treat male pattern baldness (androgenetic alopecia). It works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). High DHT levels contribute significantly to hair loss.
Propecia’s effectiveness varies, with many men experiencing hair regrowth or slowed hair loss. Results aren’t immediate; consistent use over several months is necessary to see noticeable changes. Hair loss may resume after stopping treatment.
Before considering Propecia, consult a healthcare professional. They can assess your suitability, discuss potential side effects, and address any concerns. Common side effects include decreased libido and erectile dysfunction, although these are not experienced by all users. Rare but serious side effects exist, demanding immediate medical attention.
