I am 23, and a bit worried about whether I am starting to go through male pattern baldness. I am just wondering when I would need to start treatment for it and what would be the most suitable treatment when I start. I am really not at an age where I feel ready to lose my hair. My Dad's side have all tended to start balding in their mid-late 20s and my Mum's side have totally good hair all their lives. However, I have been seeing 4-5 hairs come out when I have been washing my hair and this is what is unsettling me. I went to see my doctor but he said I had good hair and that I am not balding, I don't know whether to believe him or not because they generally don't have a clue about male pattern baldness.
