For the last 10 years I have had a problem with my scalp. It started out of the blue, my scalp became very itchy and I could not help scratching it, when I scratched it, what appeared to be white flakes of skin came off. I thought this was just normal dandruff so bought Anti-dandruff shampoo (over the years I have tried every Anti-dandruff shampoo you can think of, even stuff from my GP). But I don't think this is normal dandruff, it isn't like dry flakes that fall off, it is as though it sticks to my scalp (which is very greasy not matter how much I wash it) and just builds up getting itchier and itchier until I give in to scratching it, thats when the flakes come off along with loads of my hair. The flakey skin feels greasy (possibly this could be wet dandruff, which I hadn't even heard of until recently). As mentioned earlier I have tried products prescribed by my GP, Polytar shampoo and Betnovate lotion, neither of these have worked. Other than using an Anti-dandruff shampoo everyday and trying my hardest not to scratch I don't know what else to do. HELP!!!
