Finasteride targets the enzyme 5-alpha-reductase, responsible for converting testosterone into dihydrotestosterone (DHT). High DHT levels shrink hair follicles, leading to hair loss.
By inhibiting 5-alpha-reductase, Finasteride reduces DHT production. This allows hair follicles to remain healthy and grow normally, slowing hair loss and potentially promoting regrowth.
Results vary, but many men experience significant improvement in hair density. It’s most effective for men with male pattern baldness (androgenetic alopecia).
Finasteride is a prescription medication, so consulting a doctor is vital before use. They can assess your suitability and discuss potential side effects, which are generally mild but can include decreased libido or sexual dysfunction in some cases.
Regular use is key for maintaining results. Stopping treatment may lead to a return of hair loss. Your doctor will provide guidance on proper usage and long-term management.
