We have had the same problem with my step daughter and her mom (we have full custody) i took her to her pediatrician and we found out she was taking too hot of a shower and using the wrong shampoo (adult stuff) She also has mild excema which made everything worse it is like cradle cap that babies get all she told us was not so hot of a shower or bath, kids shampoo (adult stuff is still too strong) and to use cradle cap (in the baby section) or a littl mineral oil on the spot every night and comb it out good.
