my son started loosing hair over the summer in patches on his arms and legs. He has less hair now after a few months but his scalp is fine and doesn’t have patches. The dermatologist said that if it hasn’t reached the the hair on his head yet is a good sign. My brother list all his hair at the same time when he was about 13 when my parents separated. My son has ADHD and is a weet boy but does not have many friends. My brother is now 36 and his hair is all back but it took years. Does anyone have similar cases of hair loss only on the body but not on the head? Thank you so much for the input.
