I'm actually in the process of trying to stretch my hair washing out. Everything I've read recently suggests that the longer the hair the longer you should go between washes, because of the fact the natural oils aren't getting to tips and your hair will be unhealthier the more frequent you wash it (weird huh?!).

My problem isn't so much oily hair, but my scalp goes all awful due to scorisis (sp?). But I'm still trying. And TBH my hair is looking a lot healthier for sure.
