Kérastase Blond Absolu Cicaplasme Leave-In Treatment 150ml is a professional all-in-one styling cream and heat protecting primer engineered to smooth rough textures, control stubborn frizz, and deliver high reflective shine to lightened locks. It functions as a blonde hair repair fluid, preparing, nourishing, and protecting fragile hair structures before using styling tools.
Apply a hazelnut-sized portion of this lavender-tinted gel-fluid styling milk through the mid-lengths and ends of clean, damp, towel-dried hair after showering, keeping it away from your roots. Comb through with a wide-tooth tool to distribute the cream uniformly, then proceed to blow-dry or style with hot tools without rinsing. While it is primarily recommended for damp hair, some users have noted effective results when lightly applied to completely dry hair to seal flyaways between wash days.
Yes, the formula provides a powerful thermal shield that protects weak, bleached, or highlighted hair structures from hot tools up to 230°C. The smart thermo-protective properties wrap an invisible protective sleeve around each strand, locking essential inner hydration inside the cuticle layer and preventing thermal degradation.
No, despite its highly intensive smoothing and softening qualities, the cream has an ultra-absorbent texture that sinks directly into porous hair fibers. It leaves no heavy synthetic coating or greasy residue behind, ensuring fine hair textures retain their natural body and feel silky soft.
This formula smooths down the rough, raised edges of the hair cuticle layer, providing critical moisture and wrapping each strand in an invisible smoothing shield. By blocking damp external air from invading the hair shaft, it effectively stops midday swelling, stubborn static flyaways, and puffy textures.
Absolutely. Wavy, straight, or coarse silver and gray structures are naturally porous and lose moisture rapidly, leading to brittle textures and brassiness. This leave-in cream provides an extra dose of care, sealing down open cuticles on contact to protect your natural brightness, prevent yellowing, and unlock deep touchable softness.
We recommend keeping this leave-in treatment focused away from your roots. Your scalp produces its own conditioning oils naturally, so apply this formula from the ears down to focus exclusively on older, drier sections that actually face mechanical friction and styling damage.
Yes, by providing an immediate detangling effect and smoothing the hair surface, this cream allows your brush or comb to slide through wet lengths effortlessly. It significantly lowers physical friction and mechanical styling tension, acting as an anti-breakage primer that directly protects fragile strands from snapping.
The formula relies on a powerhouse blend of pure Hyaluronic Acid to intensely plump and fill in porous gaps along bleached hair strands, combined with antioxidant-rich Edelweiss Flower Extract to soothe sensitive strands and shield fragile fibers from daily environmental stress.
The standard retail size of this professional leave-in treatment is a 150ml squeeze tube. Because the nourishing, cuticle-sealing formula is highly concentrated, a single tube lasts for many weeks since you only need a small portion for each regular styling session.

I was excited by all the good reviews but when I first used this it made my hair very oily, so I assumed that I used too much (although I have super thick hair ...
