propecia by merck and co
Propecia, manufactured by Merck & Co., is a pharmaceutical treatment primarily used for male pattern baldness, or androgenetic alopecia. The active ingredient, finasteride, works by inhibiting the hormone DHT, which is responsible for shrinking hair follicles on the scalp. This medication comes in tablet form and is typically taken once daily. Proven effective through clinical studies, it can help men regrow lost hair and prevent further hair loss when used consistently over time. However, like any medication, it may have side effects, including decreased libido or erectile dysfunction, which should be discussed with a healthcare provider before starting treatment.
