I received the Chi Infra Shampoo free at the resort I was vacationing and decided to give it a try instead of the shampoo I typically purchase. This product is amazing. I have never had my hair left so soft, and tangle free. I noticed a difference in my hair within a week. It had moisture, volume, and became soft to the touch. I have really long hair and typically have to use a lot more of a product when applying but I do not require as much CHI shampoo when applying Although this product can be quite expensive I think it is a product worth purchasing and if not using on a regular basis then having it to use when your hair need a pick me up. I think that it's worth the money you pay for the product quality you receive and I don't think you will be disappointed.
