I have the other two products in the Protein Recharging Shampoo and Protein Hair Milkpack series - two unique products for my damaged hair! And I needed a third product from the same series and brand to complement the wonderful other two, which new product to serve as a treatment, conditioner or mask to use immediately after the protein shampoo and which to rinse. So that I can then apply Protein Hair Milkpack. Perfect and exclusive! Thanks!
