KEY INGREDIENTS
![]() |
Hyaluronic Acid Two distinct molecular H.A. weights are used in the Blond Absolu range: The low molecular weight H.A. has been shown to penetrate the hair fiber, improving resistance, while the high molecular weight has shown to enhance smoothness, and provide a plumping effect. When combined, these two H.A. are designed to deliver benefits both on the inside and outside of the hair fiber. |

Vitamin C+E The number 1 skincare brightening ingredient Vitamin C & the strong anti-oxidative Vitamin E, combine their power to brighten the fiber cuticle. Vitamin C is shown to help maintain the integrity of the hair fiber, while the Vitamin E is especially studied for it's ability to protect hair against oxidative damages |
