Hat Wearing Baldness

Do I have male pattern baldness?
In short, he was losing so much hair and I noticed a white spot on his temple development. However, I have enough family history of baldness (neither the mother nor the side of my father's side). Accompanied the loss of air is a significant amount of film and general irritation and itching of the scalp. Also, I'm only 21 years. For these reasons, I wonder if I'm naturally bald (looks like a situation abnormal because I'm the only person on either side of my family to have to happen) or if I'm showing symptoms of something else? Any help and guidance would be great. a little concern. Also, if it helps, I wear a hat a lot. This could cause a sort of film / irritation
these symptoms are HIV friend AIDS …. I would get this extract
