I have small, brown, winged bugs in my hair, but they're bigger than lice. Plus, my scalp is very itchy. What do I do?

Probable lice. Hello. Actually the kind of bugs you're describing DO sound like lice, and they can cause scalp itching. There are several non-prescription products available such as permethrin that can be applied, followed by combing out the eggs with a nit comb. You could also use a "smother" technique with Cetaphil cleanser blow-dried into the air and left on overnight. It is also important to wash fomites.
