I was really excited to see that MooGoo has put out a dry shampoo because I Iove their leave-in conditioner. Upon reading the ingredients, however, I discovered that they use baking soda.

I've read that baking soda is really bad for your hair and scalp because it is abrasive and has a very high pH (while scalp and hair are happiest in an acidic environment). I've also seen someone write on the internet somewhere that these two things can ruin the di-sulphide bonds in hair over time, effectively destroying your hair.

Should baking soda in dry shampoo be avoided? It looks to be a common ingredient in dry shampoo though the LHC hair guru Nightshade has one without out it.
