KÉRASTASE Densifique Densité Thickening Shampoo Refill 16.9 oz — Hyaluronic Acid for Fuller, Stronger Fine Hair

KÉRASTASE Densifique Densité Refill Shampoo is a salon-grade, hyaluronic-acid–enriched cleansing refill that gently removes buildup while helping hair look fuller, thicker and more resilient.

This 500 ml (16.9 fl oz) eco-friendly refill pouch offers the same professional-strength formula found in Kérastase salons, designed to boost texture and body in fine or thinning hair. The gentle, daily-use shampoo cleanses without stripping, supports hair fiber strength, and refreshes the scalp to reveal hair with improved substance and shine. Packaged to reduce plastic waste, the refill pouch is made from recycled materials and replaces two 250 ml bottles’ worth of packaging.

How does this shampoo make fine hair appear fuller?

The formula contains hyaluronic acid and ingredients that target hair fiber resilience, helping hair maintain lift and movement from root to tip. Regular use cleanses away residues that weigh hair down, while the conditioning agents leave strands with more body and visible density.

• Hyaluronic acid helps plump hair fiber surface for added texture.
• Lightweight conditioning avoids heaviness that flattens fine hair.
• Daily cleansing removes product and environmental buildup.
• Professional-grade surfactants preserve natural shine and bounce.

Will this refill be easy to use and environmentally better than bottles?

The pouch is designed to pour into an existing Kérastase pump bottle, making refilling straightforward and spill-minimized when you follow the simple refill steps. It uses significantly less plastic than buying two standard 250 ml bottles, and the pouch itself is produced from recycled plastic components (excluding pump and additives).

• 500 ml pouch replaces two 250 ml bottles’ plastic footprint.
• Made with recycled plastic (pump and colorants excluded).
• Refill instructions: remove cap, pour into unrinsed empty bottle, note date and batch.
• Compact pouch shape reduces shipping volume and storage space.

How should I use the shampoo for best results?

Apply to thoroughly wet hair, massage to create a rich lather, then rinse completely; repeat if needed. For a full regimen, follow with a compatible Densifique conditioner or mask to lock in texture and resilience without weighing hair down.

• Use daily or as needed for a deep but gentle cleanse.
• Massage into scalp to lift and stimulate follicles during cleansing.
• Rinse thoroughly to avoid residue that can flatten hair.
• Avoid eye contact; rinse immediately if contact occurs.

Is this safe for color-treated hair and daily use?

The formula is crafted for frequent use and is gentle enough for color-treated hair when used as directed; it focuses on cleansing and strengthening rather than aggressive clarification. As with any salon product, pair with color-protecting treatments if you want additional fade protection and consult your stylist for personalized routines.

• Suitable for daily cleansing of fine, thinning, and color-treated hair.
• Non-stripping surfactant balance protects natural and color-treated hair oils.
• Works best combined with Densifique serum or conditioner for targeted benefits.
• Professional formulation intended for at-home salon-quality care.

Who is this for: KÉRASTASE Densifique Densité Refill Shampoo is aimed at people with fine, limp or visibly thinning hair who want salon-quality cleansing that supports texture, density and shine without heavy residue. It’s ideal for anyone seeking an eco-friendlier way to keep their existing Kérastase pump bottle topped up while maintaining a routine that enhances volume, fiber strength and manageability.
