KERASTASE Blond Absolu Cicaplasme Serum - Hydrating Leave In Serum

In this review the KERASTASE Blond Absolu Cicaplasme Serum is presented as a targeted leave-in treatment for color treated and blonde hair that primarily reduces frizz while protecting from heat. The serum's biggest single reason to buy is its combination of lightweight hydration and high-temperature protection, which helps keep color vibrant and strands smooth. Reviewers repeatedly note the silk-like softness and visible shine it imparts, making it a solid choice for anyone who needs daily frizz control without weighing down fine or chemically treated hair.

Key Features

• Hydrating formula: Leaves hair feeling soft and moisturized without heaviness, which helps fine hair remain bouncy rather than limp.
• Heat protection up to 450F: Shields color treated strands from high-heat styling tools to reduce breakage and preserve color integrity.
• Strengthens hair: Formulation helps fortify fragile, treated hair to prevent breakage during styling and brushing.
• Frizz control: Smooths flyaways and reduces frizz for a sleek finish that enhances shine.
• Pleasant scent: Adds a subtle fragrance that customers consistently mention as a positive sensory detail.

Who It's For

The serum is best suited to people with blonde or color treated hair who want a lightweight, daily leave-in that controls frizz and protects against heat damage. It performs well on fine to medium hair textures where a non-greasy finish and added shine are priorities.

Those with very coarse hair or who need intensive reconstructive treatment for severe damage may prefer heavier masks or professional repair treatments instead of this light leave-in serum. Also, shoppers seeking a budget option may find the price higher than drugstore alternatives.
