Jack had a teeny tiny bit when he was about 6wks old and i'm talking a tiny patch on top of his head, I caked his hair in olive oil and left it for about 30mins, then gently massaged his head and washed it off in the bath, it came off completley and never came back! He really did have a mild case though, I guess it's just trial and error of all the different methods until you find one that works for you LO x
