Okay, so I decided to do this and am on Day 5 of water only washing. I think I have enough grease in my hair now to get some dreadlocks going. When does this get better? I'll tough it out for a couple of more days and then perhaps try a baking soda rinse to cut some of the grease. I'm really determined to say goodbye to shampoo and all its nasty chemicals but the process is not for those who are excessively vain.
