ego egozite cradle cap lotion,you can get it from chemist just on shelf,my DD had the worst alot of people said theyd seen,you have to leave it on if i remember for like 3 days so we did it while we on holiday as its greasy but it was the only thing that worked i think i used a baby comb to help with getting it off,i also tried the olive oil that helped also but this was the only thing that got it all off.
