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 brightens 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
Why does lightened and bleached hair get brassy?
Bleaching and lightening the hair means removing the hair’s natural pigments which can reveal unwanted undertones. When bleaching dark based hair colour, red or orange undertones can appear. Even light-based hair colour can reveal unwanted undertones when bleached. Blond Absolu Masque Ultra-Violet hair mask has Ultra-Violet Neutralisers in its formula to cancel out unwanted undertones and help get rid of brassiness.
Why should I use Masque Ultra-Violet?
Masque Ultra-Violet should be used to reduce hair's brassiness, and neutralise yellow undertones in order to reveal a bright & intensely nourished blonde.
How often should I use Masque Ultra-Violet?
Use Masque Ultra-Violet weekly to get rid of brassiness and unwanted undertones. Complement by using Cicaflash on other wash days.
Will the Masque Ultra-Violet make my hair purple?
We advise leaving the Masque Ultra-Violet hair mask on for a maximum time of 5 minutes then rinse off completely. This product does not stain nor will it turn your blonde hair purple if used properly.
