psoriosis, is like exzeema but on the scalp
Don't scratch! Whatever you do!
I'm sure you've tried dandruff shampoo, so if that isn't working, you'll probably have to go to a dermatologist. Skin doctors often have prescription shampoos that you can use.
before you go to bed at night put some bag balm on it.try it for 5 days and see if it helps,if it does cut back to every other day,then to maybe two times weekly
Go to your doctor and ask for somthing for it, he/she will know what to do.
