health food stores are usually good sources for hair products if you are looking for something gentler than the norm.
I have Desert Essence Italian Grape shampoo, currently, and am liking it.
As for baby shampoo, I have heard that the pH is harsh (too high? to low? can't remember which). I think I read this on the BB somewhere months back.
my Fotki hair journey/experiment diary PW is brio (and I really need to update it!)
3A hair; coloring with henna/indigo since July 2009; normally follow the CG method. Still searching for my HG products!
