My friend, Mandy has the frizziest hair I have ever seen. She has tried so many things to tame her hair. She asked me if I had ever used a hair treatment that made my hair shiny and manageable. I told her there is a shampoo and conditioner that I use and it keeps my hair healthy because it has keratin in it. She came over to my house to see what shampoo i used and said she had never heard of it. She then asked me if she could borrow it and I told her no! I would order some for her.
