You might need a consult with a Dermatologist. The caked up gunk might be psoriasis or some other skin problem. There are prescription shampoos and treatments that work. As for the texture of your hair, if it's frizzy and looks like crap by mid-day then you are going to need to go to a GOOD salon. Not "Quick Cutz" or whatever. A good stylist will chat with you first and help you with your issues. Good Luck!
