Propecia, manufactured by Merck & Co., is a widely recognized medication primarily used to treat male pattern baldness. Its active ingredient, finasteride, works by inhibiting the hormone responsible for hair loss, promoting both hair regrowth and preventing further hair thinning when used consistently. Approved by the FDA in 1997, Propecia has become a staple in dermatology practices and is available by prescription only. Patients often notice improvements in scalp coverage within several months of use, though individual results can vary. As with any medication, it's important to consult a healthcare provider about potential side effects and contraindications before starting treatment.
