KÉRASTASE Densifique Densité Thickening Shampoo Refill 16.9 fl oz — Hyaluronic Acid for Fine, Thinning Hair

Kérastase Densifique Densité Refill is a salon-grade thickening shampoo in an eco-friendly 500ml pouch that cleanses, strengthens hair fiber and boosts visible fullness with hyaluronic acid.

Designed for fine or thinning hair, this refill pouch delivers a daily deep-cleansing formula that targets weakened strands and surface build-up while restoring texture and body. The lightweight, hyaluronic acid–infused formula helps hair feel more resilient and look denser without weighing it down. Packaged as a sustainable refill, the pouch reduces plastic compared with standard bottles and lets you top up your existing pump container.

How does this shampoo make hair look fuller?

The formula works on fiber structure and surface lift rather than adding heavy coatings. Hyaluronic acid helps improve hair texture by supporting moisture balance and smoothing the cuticle, which creates the appearance of thicker, more buoyant hair. Regular use enhances the hair’s natural body and bounce for a visibly fuller finish.

• Hyaluronic acid supports hydration and texture improvement.
• Daily cleansing removes residue that flattens hair at the root.
• Lightweight formulation avoids weighing fine strands down.

Will this product help with buildup and shine?

Yes—Densifique Densité is a deep-cleansing shampoo designed to lift oils, styling residues, and environmental buildup that dull hair. By clearing the scalp and strand surface, it restores natural light reflection and improves overall shine without stripping necessary moisture.

• Deep-cleansing action removes excess sebum and product residue.
• Gentle enough for daily use to maintain a clean scalp environment.
• Leaves hair with renewed surface smoothness for enhanced gloss.

How do I use the refill pouch and integrate it into my routine?

Use on wet hair: apply, massage to emulsify, then rinse thoroughly. To refill a pump bottle, remove the pouch cap and pour into an empty, unrinsed container; note the refill date and batch number. Pair with complementary treatments from the Densifique range for targeted densifying care.

• Apply to wet hair, massage, and rinse; avoid eye contact.
• Pour into your existing pump bottle to reduce waste.
• Recommended for daily use and as the cleansing step before densifying serums or masks.

What sustainability benefits does the refill pouch offer?

The 500ml refill pouch reduces plastic consumption significantly compared with two 250ml bottles, using 82% less plastic packaging. The pouch is made from largely recycled plastic (excluding pump, colorants and additives), making it a more environmentally mindful option for regular users of the Kérastase Densifique line.

• 500ml refill pouch designed to cut plastic waste versus multiple bottles.
• Pouch composition includes recycled plastic components.
• Refill system encourages reuse of salon-style pump bottles.

It suits daily users who prefer a lightweight, hyaluronic acid–inspired formula and shoppers seeking a greener refill option to reduce single-use plastic. Use as your regular shampoo or as the cleansing first step in a targeted densifying regimen.
