Hair spa brings dry and damage hair shine, moisture and smoothness, thanks to the coordination of a coating silicone derivative and a treatment cationic surfactant. The coating silicone derivative makes the hair supple and glossy without weighing down. The treatment cationic surfactant treats the surface of the fibre where it is more sensitised to leave it smooth and soft. Result: shiny and easy to de-tangle hair with a silky feel from the roots to ends.
