yo so i have the sickest dandruff ever. sometimes its wet and oozes, sometimes it's dry as hell. i've tried different shampoos, acv rinses, baking soda, and now i'm pretty certain that i get it from a food allergy. a lot of times when i eat ice cream and certain hot sauces my head begins to itch pretty bad during the first bite. i figure that the common denominator between the two foods is some sort of food preservative, and i also figure its in a lot of things i eat, since i have mad dandruff. it could also not be the sole cause, but just another factor that makes it so bad. who knows. too bad i'm not insured or i could get an allergy test. oh well.
