Balding Man Gets Fringe Tattooed On His Head

Alopecia areata 

If you get small patches of hair loss, like circles, that crop up on the scalp, this is known as alopecia areata. It’s thought to be an autoimmune condition, this a condition where the body starts to accidentally attack itself, rather than fight off bugs. Cells in the immune system gather at the hair follicles and attack it, causing the hair to fall out. This kind of hair loss can be set off by recent illness, certain medications or stress, but often no direct cause can be identified.
