I've been getting my hair dyed at the Aveda hair salons using only Aveda hair color. I was recommended to use the Color Conserve Shampoo and Conditioner. I must be an optimist because I thought the shampoo was working well until it was so dry and frizzy. It was tangled and knotted horribly. I had breakage and I just refused to believe it was the Aveda products. Until I bought John Freida's shampoo for dry frizzy hair and it miraculously looked better in one wash. So as much as I wanted to be an advocate of natural Aveda products they ruined my hair. So disappointed.
