The Reality of Caring for Blonde Hair – and Why Blonde is Not Just One Concern
Blonde hair is radiant, versatile, and endlessly desirable. But no two shades are the same – and neither are their concerns. Cool blondes battle brassiness, warm blondes fight dullness, while natural blondes struggle to keep their tone looking fresh.
Kérastase Blonde Absolu was formulated to solve the universal struggles of being blonde – balancing colour maintenance with the deep hydration your hair needs. Using the science of brightening hydration, this collection neutralises unwanted tones and locks in moisture across every shade, delivering the brightest, most hydrated blonde you've ever imagined.
Below, we break down the full Blond Absolu collection and how each product targets the specific needs of your blonde.
The Trials and Tribulations of Being a Blonde: Common Hair Concerns
Being blonde often means your hair shows change faster. A few washes, a week in the sun, too much heat styling, or one swim in chlorine can leave your colour looking warmer and your hair feeling drier.
Most blonde concerns fall into two categories:
Texture Stress: dryness, split ends, brittleness, breakage, and thinning.
Colour Distortion: brassiness, dullness, and unwanted yellow tones.
Because brightness, softness, and strength all need to be addressed at the same time, juggling these concerns can make caring for blonde hair feel harder to maintain. This is why you need a blonde hair care routine that suits your unique blonde shade and hair care goals.
