For male pattern hair loss, we use oral medication that reduces production of DHT, the male hormone involved in hair loss, and topical medication (minoxidil) that supports scalp blood flow and hair growth. Consistent use for at least 3 to 6 months is usually needed to assess the effect. If treatment stops, hair may return to its pretreatment state within a few months.
Oral medication can rarely cause side effects such as reduced sex drive. It also lowers PSA, a marker used in prostate testing, so you must tell the clinician at your health checkup that you take it. Women of childbearing age do not take this oral medication and should avoid handling broken tablets.
