Hair loss treatment medication helps slow hair loss, improve hair growth, or manage certain conditions that affect the scalp and hair follicles. Common treatments include topical minoxidil and prescription medicines like finasteride, which is good for specific types of hair loss, including male pattern hair loss. Effectiveness can vary depending on the underlying cause, age, health, and duration of hair loss. Some medication require continues use to maintain results and may cause side effects such as scalp irritation, itching, dizziness, or hormonal changes.
