SCIENCE:

REASONS BEHIND THE BLONDE STRUGGLE

Blonde hair has inherent structural differences and susceptibility to external aggressors like UV damage, heat, chlorine, salt water, and dehyration. These underlying structual vulnerabilities lead to what is comminly termed as "The Blonde Struggle."

DEMANDING TEXTURE: Characterized by dryness, thinning, and split ends which are all a direct result of a compromised hair structure often due to the lightening process and environmental stress.

COLOR DISTORTION: This includes brasiness and dullness which arise from pigment degradation, increased porosity, and the absorption of unwanted tones.

The Blond Absolu philosophy is that overcoming these visible challenges necessitates an in-depth comprehension of the biological structure and the environmental pressures that often overcome blonde hair.

THE SCIENCE OF BLOND ABSOLU

Brightening Hydration

Blond Absolu's advanced system is formulated to deliver unparalleled brightness and intense hydration through the combination of hyaluronic acid and vitamins C+E.

Vitamines C+E : Known for its benefits in skincare, brightening ingredient Vitamin C and 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.
Hyaluronic Acid : The low molecular weight H.A. has been shown to penetrate the hair, 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.
