Propecia, containing finasteride, works by inhibiting the enzyme 5-alpha-reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), a hormone contributing significantly to hair loss in men with androgenetic alopecia (male pattern baldness). By blocking this conversion, Propecia reduces DHT levels in the scalp, thereby slowing hair loss and potentially promoting hair regrowth.
How it impacts hair growth
The reduced DHT allows hair follicles to remain in the growth phase for longer. This leads to thicker, healthier-looking hair. It’s important to note that Propecia primarily slows down hair loss; results vary, and consistent use is key for optimal outcomes. It doesn’t address all types of hair loss.
Who should use Propecia?
Propecia is specifically designed for men aged 18 to 41 experiencing male pattern baldness. Consult your doctor before use. They can assess your suitability and discuss potential side effects. Remember, Propecia is a prescription medication requiring medical oversight.
