I am 28 years old male. facing male pattern hair loss from last two years. need to know what medication need to be taken to avoid hair loss?

Several options: In addition to the Minoxidil which i see that you are using, you may try Propecia / finasteride. There are also surgical options. Or you may decide instead to embrace your masculinity and genetic heritage and opt for no treatment. You're a man, and looking good is 95% physical fitness, which unlike hair restorers actually makes you healthier. Photo guy isn't complaining. Best wishes.
