KÉRASTASE Densifique Thickening & Strengthening Shampoo — 8.5 fl oz, Hyaluronic Acid for Fine, Thinning Hair

KÉRASTASE Densifique Densité Shampoo is a luxury thickening cleanser that gently removes buildup while plumping and strengthening fine, thinning hair with hyaluronic acid.

This salon-grade shampoo is formulated to address hair that lacks density: it clarifies the scalp, restores lightweight moisture and improves the appearance of fullness from root to tip. Blending hyaluronic acid with a gentle cleansing base, the formula targets factors that weigh hair down and helps deliver more body and shine without stiffness.

How does this shampoo make hair look fuller?

The formula uses hyaluronic acid to increase the hair fiber’s apparent diameter and retain lightweight moisture, which makes individual strands appear plumper. By removing excess oils and product buildup at the scalp, it also prevents flatness so styles hold more lift and bounce.

• Hyaluronic acid plumps individual strands for more visible thickness.
• Clarifying action removes residue that flattens roots and mid-lengths.
• Light conditioning maintains soft texture while boosting body.

Will it strengthen fragile or thinning hair?

While not a medical treatment, the shampoo supports healthier-looking hair by reinforcing fiber resilience and reducing the appearance of breakage. Regular use helps protect hair against daily stresses, leaving strands smoother and less prone to snap when styled.

• Formulation targets weakened fibers to improve manageability.
• Reduces factors that contribute to brittle texture and split ends.
• Pairs with Densifique conditioner or mask for added fortification.

How should I use it for best results?

Apply a quarter-size amount to soaking-wet hair and distribute from scalp to ends, gently massaging to dissolve dirt and buildup. Rinse thoroughly and follow with the matching conditioner or mask in the Densifique range to lock in volume and nourishment.

• Use on wet hair; concentrate at roots for clarifying benefits.
• Rinse completely to avoid residue that can weigh hair down.
• For greater thickness, use with Densifique Conditioner or Mask.

Does it work for color-treated or sensitive scalps?

The gentle cleansing system is compatible with color-treated hair and is designed to avoid stripping, while also addressing common scalp concerns like mild dryness or product-related flakiness. If you have a medically sensitive scalp, consult a dermatologist before changing products.

• Safe for colored hair when used as directed; preserves color vibrancy.
• Helps clarify without over-drying when rinsed thoroughly.
• Not a medical treatment—seek professional advice for scalp conditions.

Who is this for: KÉRASTASE Densifique Densité Shampoo is made for people with fine, limp, or visibly thinning hair who want a premium cleansing experience that adds volume and shine without stiffness. It’s ideal for anyone looking to reduce buildup, improve the look of density, and pair with targeted conditioners or treatments for a fuller-looking finish.
