Kérastase Symbiose Microexfoliating Cellular Treatment is a professional pre-shampoo dandruff treatment and advanced micro-exfoliating scalp scrub engineered to instantly dissolve loose flakes, target flaky scalps, and clarify the skin surface. It combines gentle plant-based exfoliating beads with chemical alpha-hydroxy acids to sweep away cell buildup and product crust before cleansing.
Before shampooing, apply Kérastase Symbiose Microexfoliating Cellular Treatment directly to the scalp onto completely wet hair roots, section by section. Add a small touch of water to activate the formula, massage the beads gently across your scalp skin for a couple of minutes to loosen stubborn dead cell layers, then rinse thoroughly. Follow immediately with a designated anti-dandruff shampoo.
The formula blends a potent 1.9% concentration of Salicylic Acid to chemically dissolve the cellular bonds holding dry dead skin buildup together, combined with micro-exfoliating argan shell powder particles to manually buff away dead skin cells and product buildup. It is enriched with calming prebiotics to protect the skin barrier and soothe a sensitive, irritated scalp microbiome.
Customers can expect immediate cooling relief from localized itching, redness, and scalp irritation. The micro-exfoliation promotes a significantly healthier, deeply purified scalp environment, creating an ideal foundation that allows your strands to grow strong. Many users report highly visible results within just a few days of use.
We suggest using this pre-shampoo dandruff treatment two to three times a week during an intensive flake flare-up window. Once your scalp skin builds back its natural balance and visible flaking is controlled, you can scale back to using it once a week for regular maintenance.
Yes, the formula is colour-safe and perfectly safe for highlighted or bleached hair types. It gently clears away dulling tap water minerals and heavy product crust from your roots, helping your lengths feel light and airy without stripping away or fading your salon shade.
Yes, by thoroughly scrubbing away heavy sebum layers, dry skin crust, and dry shampoo buildup from the base of the hair fiber, this pre-wash treatment adds an instant lifting effect, leaving thin or limp roots looking visibly voluminous, airy, and full of bounce.
If your scalp skin currently has open scratches, raw bleeding sores, or intense active irritation from aggressive itching, avoid using this salicylic acid scalp exfoliator. Let your skin barrier heal completely first to prevent the active fruit acids from causing a stinging sensation.
The standard retail size of this professional treatment is a 200ml squeeze tube. Because the fluid gel formula spreads easily across wet skin with only a small portion needed for each section, a single tube lasts for many weeks of consistent use.
Yes, this product is explicitly formulated as a pre-wash primer to loosen and dissolve dead cellular deposits. You must always follow it with an anti-dandruff wash, like the Bain Hydrating or Bain Purifying shampoo from the same line, to completely wash away the loosened particles.
Absolutely. Men frequently deal with high sebum production and stubborn product crust from heavy styling pomades, making this micro-exfoliating scalp scrub an exceptional addition to their routine to keep their scalp skin feeling completely clarified and fresh.
It features a gorgeous, upscale aroma developed by master perfumers. Kérastase Symbiose Microexfoliating Cellular Treatment blends refreshing top notes of mandarin and blood orange with a delicate heart of white florals and warm amber, eliminating the traditional medicinal smell common in flake treatments.
