M1my daughter did not have this problem, but my noncah son did and it had nothing to do with cah. By the time he was 6 months ald all of his hair fell out. He was born with a head full of fluffy hair. I had to change his sheet everyday because every morning there would be hair on it. Then of course all of his hair grew back.
My daughter had a head full of thick dark hair and now has enough hair for 4 people! My son has thinner hair than she does and it is straight. Not every kid is alike.
