Because I love GC I will share my new secret with you
Try Sexy Healthy Hair by Sexy Hair Concepts. It's the only soy based hair care line and read the ingredients... they all have soy milk, soy protiens, and/or oatmeal and wheat proteins.
I use the shampoo and conditioner as well as the once a week leave in conditioner. Some K-Mart's are selling it, but I get it at my salon. All products are usually $7-$10 which isn't bad for a salon line.
