My pre-teen daughter wants to grow her long, but she is brutal with the care and maintenance of it. It is torture to watch her brush through it several times throughout the day. I knew I needed to get her a shampoo and conditioner that would strengthen and protect her hair. That's why I bought the beautiful lengths shampoo and conditioner for her. What a difference! She has been using both for about a month now and her hair is soft and most of the frizz from split ends is now gone. Her hair is smooth and shiny - and I think she will now reach her goal of long hair.
