Kérastase Blond Absolu Blonde Guard 190ml is an innovative hydrating wonder shield leave-in, formulated to protect all types of blondes from their main aggressors: heat, UV damage, chlorine, salt water and dehydration.

This lightweight fluid milk instantly absorbs into the hair fibre, revealing softer, easily detangled and hydrated blonde hair while providing complete protection. That combination is the point: most blonde products tone or repair after the damage, where this one is designed to stop it happening.

Powered by Brightening Hydration science, the formula features Hyaluronic Acid in two molecular weights, to hydrate deeper and lock in moisture by forming a hydra-barrier. Complemented by super anti-oxidative and brightening Vitamins C and E, it forms a protective wonder shield that keeps all types of blonde hair bright, hydrated and protected.

The scent is a contemporary clean luxury blend of dazzling citrus with blooming florals, leaving a lasting trail full of youth and audacity. The bottle is made of 95% recycled plastic, excluding pump and labels.

What are the key ingredients?

Hyaluronic Acid: Used in two molecular weights. The low molecular weight penetrates the hair fibre to improve resistance, while the high molecular weight enhances smoothness and provides a plumping effect, so the two work inside and outside the fibre.

Vitamins C and E: Vitamin C helps maintain the integrity of the hair fibre and brightens the cuticle, while Vitamin E protects against oxidative damage.
