My older two children had cradle cap as babies which has coem and gone, but now it seems to be back again and they are 6 and 4. Theire heads are really scaly, with thick crusts of skin flaking off, nothing like normal dandruff, and I have to be careful because if I rub it too much, their hair comes off with the skin. Poor dd is looking very thin on top. We've been to the GP several times before, even had medication especially made up at the hospital but with no real luck.
