propecia 5mg over the counter
Propecia, known generically as finasteride, is a medication used to treat male pattern baldness and is not available over-the-counter; it requires a prescription. This drug works by inhibiting an enzyme responsible for converting testosterone into dihydrotestosterone (DHT), which is linked to hair loss in susceptible individuals. By reducing DHT levels, Propecia helps prevent further hair loss and can even promote regrowth in some users. It's important to note that while effective, it may not work for everyone and should be used under medical supervision due to potential side effects such as decreased libido or erectile dysfunction. Always consult a healthcare provider before starting any new medication regimen.
