Davines glorifying elixir anti age Pure youth for coloured and bleached hair. Additive that has been studied to offer an anti-age colouring service purposely targeted at mature women. The elixir counteracts by creating a protective film able to contrast the aggression of free radicals, molecules that are highly unstable present in the environment, that damage what they encounter (skin, hair, all types of materials). Product can be mixed in to the colour as an anti age booster or as a pre-shampoo treatment to give coloured, bleached and highlighted and particularly destructured and dehydrated hair new vitality.
