So I started using Aveda's shampoo, conditioner, and scalp system for thinning hair right after Christmas. At first I thought it was doing nothing, but with continued use, I do think that less hair is falling out. It doesn't grow hair, but it's supposed to help with breakage and falling out. I'm going to finish this batch and then I have to decide if it's doing enough to justify the price. It's more than I have ever paid for hair products!
