DD is 6 years old and for about a year has suffered from a very dry scalp. Its sort of a cross between white, dandruffy 'dust' and hard, flaky yellow cradle cap.
I've tried tar based shampoos, cradle cap treatments, no shampoo, anti dandruff shampoo, coconut oil. Nothing works. It comes back within 24 hours and is really quite gross.
Should I take her to the doctor? Anything else I can try first?
