Can homeopathy cure androgenetic alopecia and what are the medicines?

It can't: If there were any cure for baldness, there would be no bald world leaders. Your physician can advise you on Minoxidil, Propecia, (finasteride) and the others, about hair transplant surgery. I'd urge you simply to get in even better physical shape. Good looks for a man is 95% physical fitness, regardless of where he does or doesn't have hair. PhotoGuy isn't complaining. It's healthy too.

Not cure but slow: "Cure"is a strong word. Homeopathy often helps problems that don't respond to conventional treatments & male pattern baldness is no exception. I wouldn't expect it to significantly reverse hair loss that's already occurred but the proper remedy might significantly slow the process down. Many remedies can help. A professional homeopath can help find the best one for you: http://tinyurl.com/l6tonns
