Latley i've been dealing with alot of dry scalp. Like when i shake my head or put my head on my pillow, flakes. Alot of flakes. Once a week i must use a sulfate because I get bad build up. Then i'll cowash every other day. The other days Ill use everyday shea shampoo. its the huge 32 ounce you get at whole foods. It says it doesnt have sulfates of any kind. its gentle on my hair and doesnt strip it, but sometimes its making my scalp be more flaky I guess?? My question is. When I cowash my scalp feels better. Alot less flakes. It isn't itchy. And im using Vo5 so its just a really cheapy cheap conditioner. I dont get it.
