Urban Care Natural's Collagen & Keratin Intensive Moisturizing Hair Care Shampoo was specially formulated for dull, dry, thin and damaged hair types. Lack of Collagen results in dryness, pale appearance and hair breakage. Collagen is a protein substance containing high amounts of amino acids providing the moisture balance of the hair and strengthening it. Urban Care Natural's Collagen & Keratin Series supports re-structuring of the hair. It helps the hair to become smooth and shiny without weighing down.
