Psoriasis is a skin condition that causes you to itch and have dandruff. I have spalp psoriasis so its only in my hair and sones times my eyebrows. It can be aggravated by stress. Another kind is called plaque psoriasis. This is red flaky patches all over the body. I have a friend with that one. She's miserable when she gets an outbreak. Oh and it's not contagious but it can be genetic for either kind.
I don't know what that is. :(
