my nephew, a 22 year old has huge red splotchy patches on his head, at first it seemed to me it was a type of psorasis, he has no health insurance, we have located some free medical support for him, however, he has yet to go. Today he shaved his entire head- the areas are 5-6 inch wide, not round, more odd shaped, some smaller areas. He used a hair color on his hair in 2007- which he says was the beginning of this- however when he scratches his head (which he does often) then his face...it has spread....i do not like having him over....because i am concerned it is contagious, however, he lives with his Dad...and he has not signs of this. My nephew is over weight; he is 5' 8" weighs about 250-270lbs, generally he is inactive- at least compared to my own 22 year old son- thoughts?
