Washing will definitely lead to stripping the body of its oils~ filth AND essential oils. Which can (and for me definitely does) cause not only the hair, but the skin as well, dry and flaky. Unfortunately for me, I've always needed to wash my hair regularly (I have very thick, dense hair, which is very oily) otherwise my skin becomes irritated and even can break out with clogged pores, rashes, and the like.. Especially running machinery with cutting oil and coolant mist. Even washing hair as much as a lot of people do isn't really recommended, I've narrowed it down to once a week to every 8-or-so days, conditioner only (no shampoo [unless rinsing out hair color :-P]). Congrats to you abn82 on your discovery!
