Is it normal for autistic step brother to shave his head since
Since my step brother was 13 he started shaving his head bald so there was no sign of hair at all. This caused a lot of confusion when he was a kid many thought he was a kid with cancer but now he's 24 and he still shaves and now waxes his head bald and he shaves his arms, legs and underarms and he puts an abundance of lotion and oil on his body so he always looks wet so it's a strange look overall.
When my parents and I try to say things like it would be nice to see you with hair on your head or I wonder what you'd look like with it or without the oil he gets really defensive and angry saying "I don't like hair on my body, hair is gross. I don't want it on me and I'll never ever have hair on my body so shut up hair is disgusting" we aren't even being serious with him just casually saying it and only maybe 5 times year at most and his tone gets mad. I'm wondering is this the autism you think?
He uses bikini wax on his head and whole body every day too. Not even a day without him walking around with bikini wax on his head and whole body.
