If you are interested in alternatives to chemical household products then I recommend looking into this. I use baking soda to wash and vinegar to rinse. I've been using it for over 6 months now and I have noticed positive changes all around. I cut my hair short to get rid of the dead ends, then I stopped using shampoo. The smell of vinegar is very strong, but once your hair dries it no longer smells. I add essential oils to my vinegar to change the scent. I'm using lemon oil right now. I have fresh, lemony scented hair after each shower. ^_^ My scalp is a lot less oily now. My hair seems to be getting thicker and stronger as well. All I can go by is how it looks and feels to me, however. I have no way to gauge it's thickness. ^_^ I'll upload before and after photos that I took to share with you.
I let my hair get oily on purpose as a test. I didn't wash my hair for 4 days and I noticed A LOT LESS oil in my hair. After 4 days it still starts to look dirty, but that's because it is dirty. *laughs* I used to get oily looking hair overnight, so this is a big change for me. I'm enjoying the new look and feel of my hair. And I hope it grows back to how long it was before soon!
