My baby has a thick layers of flakes on his skull. Is it because of the shampoo that has cause this problem?Currently I use kodomo bath and shampoo that is given in the hospital package. Should I change the shampoo to those not so harsh for baby?

What i do is, i will baby oil or olive oil to apply on his head and use a comb and have, after a few days will be better, and less flaky. It'll recover on it's own without using any cradle head shampoo or med. Unless it's very severe than i will suggest u to see doc and seek for advise instead.
