Designed to nourish damaged-looking hair, the Giovanni Biotin & Collagen Rebond and Restore Hair Oil is infused with a blend of vitamins to promote visibly stronger strands. Powered by a nutrient-rich fusion, the hair oil instantly hydrates to promote a thicker appearance. Biotin enriches brittle-feeling hair with intense nourishment to encourage a shiny finish, while hyaluronic acid locks in moisture. Infused with collagen, the hair oil works to minimise the risk of hair breakage for visibly thicker results.
