it works [SEP] definitely a toning shampoo you will notice a dramatic color difference in your hair if kept on for minutes but no regular conditioner will save you from the drying effects this shampoo has on your hair feels like you washed your hair with dish soap i recommend using a hair mask such as the joico defy damage protective masque after for amazing results i would purchase this product again because it does work but you have to go beyond using a conditioner afterwards
