Hello expert, I have a problem, the scalp of my head has a thick layer like skin, and scalp itches a lot, when those layers are scratched ,they become like white skin.. I am having a hard time. It can be anything?

A. here for proper comments is very difficult until and unless a proper examination is done to find out the exact cause so it would be better if you consult your doctor so that he can examine prophuerly and than will guide you accordingly regarding this
