Does anyone have any advice please? My 7 week old had cradle cap appear about 2 weeks ago, I didn't want to use any of the shampoos, cradle cap brush didn't work so have been using castor oil & nit comb which is working very well to easily remove it. It's now gone from the back of her head but on the top seems to be returning - is there anyway to stop it? Do I need to keep removing the flakes? Thanks for any advice x
