I used to only wash my hair with water and to be honest if you never sweat and never go anywhere with cigarettes or greasy food your hair won't smell. Naturally your hair does not smell much, it just picks up all the smells that are around it. I still only wash it with soap when it smells funny, and thats only after I go to the club or things like that. I don/t think it would actually hurt your hair at all though.
I think dreads may cling to smells more effectively then straight hair too. I wash my dreads more then I washed my hair before dreads.
When you start with dreads neglect way do you need to be extra careful when you wash your hair? How do you do it with baking soda? Do you just soak them or what? Thankful for some info :)
Once you get over your hair freaking out and make it past the oily transition period, your hair becomes very lovely. With shampoo, it strips the natural oil out of your hair, causing your hair to produce waaaaay more than it should. So naturally, when you stop your hair is still over producing. I was forced into water only after Hurricane Katrina and for about two months I wanted to shave my head totally bald. But once it evened out, my hair was fabulous. No breakage, no dandruff, no problems. Just that transition period is HELL. Though you can set up a plan where you stop using shampoo, transition to baking soda, and then slowly transition to water only. It's amazing for you hair. I'm back to baking soda only and I'm hoping one day to get back to water only. Just do a quick google of "no poo" and you should find some great resources.
