help. my 2.5yo daughter has always had sensitive skin, comes out in blotches at the slightest hint of soap. i wash her hair only with dove sensitive shampoo. recently she has started scratching at her head. Initally there were tiny scabs in the parting - perhaps midge bites, but they have now settled. I thought perhaps I wasn't rinsing the hair properly (she hates this) so i have been extra careful for a couple of weeks but there has been no improvement. no sign of nits or the like. any ideas? any shampoo recommendations? she is not scratching all the time but she no sooner has her hair up nice and tidy than she has a wee scratch and messes it all up (she scratches with her hair down too so i don't think it is irritation from the clips).
