Propecia is an FDA-approved prescription hair treatment solution that medically restores hair follicles to their natural brilliance. Propecia is meant exclusively for men to treat balding, hair loss, and receding hairlines. It’s available as an oral treatment ( 1 mg per day) only by prescription. If the patient stops taking the pill, any improvement will resort back to the original state of hair loss.
In essence, Propecia prevents testosterone from converting to DHT (dihydrotestosterone), the hormone responsible for shrinking hair follicles in men. Results can appear in as little as 6 months.
