Thank everyone I'll give them a go see which one works xx

I used dove shampoo on Arlo when he started to get it very early on and have used it since he's never had problems again xxx

Cetraben ointment got rid of Max's in a week when he was younger. Never came back.

Baby oil in the bath or before bed let it soak in and brush/comb it out is what we were told when my little girl got it
