  31. Minoxidil is a topical medication widely used for the treatment of hair loss and is particularly effective for patients with androgenetic alopecia. Originally developed as an oral medication for hypertension, its hair regrowth properties were discovered as a beneficial side effect. When applied to the scalp, Minoxidil stimulates hair follicles, prolonging the growth phase of the hair cycle and increasing follicle size. This results in thicker and more robust hair growth over time. Minoxidil is available in various concentrations, typically 2% and 5%, and can be used by both men and women. While generally safe and effective, users may experience side effects such as scalp irritation or unwanted facial hair growth. For optimal results, Minoxidil must be used consistently, and discontinuation may lead to the recurrence of hair loss.
