My hairdresser asked me have I heard of these products. She said that one of her clients have been bringing this product to her to use on her head and she said that after around 7 months of using the shampoo and conditioner, her has has grown so long that she had to cut it. I just purchased the Terax Shamp-collagene and Crema-conditioner. It seems to to make my hair pretty soft, but It will take a while to see some real results. Has anyone else used these products?
