SCIENCE
BLOND ABSOLU
ULTIMATE HAIR CARE FOR ALL TYPES OF BLONDE
Whatever your blonde hair: you dare, we care. The Blond Absolu collection provides intense nourishment and instant brightness to achieve a perfect blonde.
Blond Absolu maintains and perfects cool tones through deep ultra-violet neutralisers, intensely nourishes the hair fibre, and brigthens hair.
KEY INGREDIENTS
Vitamins C+E
Within the formula, Vitamin C & Vitamin E combine their power to brighten the fibre's cuticle and help maintain the integrity of the hair fibre.
Hyaluronic Acid
Within this formula, two distinct molecular H.A. weights are used. In this formula, the low molecular weight H.A. penetrates the hair fibre, improving resistance, while the high molecular weight enhances smoothness and provides a plumping effect. When combined in the formula, this dual-action effect helps to deliver benefits both on the inside and outside of the hair fibre.

FREQUENTLY ASKED QUESTIONS
