Haircare treatments contain a higher concentration of the active ingredients to intensely treat your hair's needs. Some treatments can be used daily such as the ELVIVE Conditioning Sprays, Serums and ELVIVE Re-Nutrition Night Elixir and Daily Nutritive Fluid. Other treatments such as the ELVIVE Masques and the ELVIVE Anti-Breakage Concentrate only need to be used once every 7-10 days as part of your standard hair care routine, depending on your hair's condition.
