Finasteride is used in the treatment of hair loss. It treats early forms of male pattern hair loss (also known as androgenetic alopecia).

Finasteride is a 5-alpha reductase inhibitor. It blocks the body's production of a male hormone in the scalp that stops hair growth, thereby reversing the balding process and preventing further hair loss.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
