KÉRASTASE Densifique Densité Conditioner — 6.8 fl oz Thickening Conditioner with Hyaluronic Acid for Fine, Thin & Thinning Hair

KÉRASTASE Densifique Densité Conditioner is a salon-grade thickening conditioner that detangles, hydrates and adds weightless volume to fine, thin and thinning hair using hyaluronic acid for plumper-looking strands.

This conditioner is designed to improve hair texture and apparent density without weighing hair down. Formulated as part of the Densifique collection, it targets fine, thin and thinning hair by moisturizing and reinforcing the hair fiber from mid-lengths to ends. The result is easier detangling, enhanced suppleness and a fuller-looking finish suitable for daily use after shampooing.

How does this conditioner make hair appear thicker?

The formula contains hyaluronic acid that helps swell and plump each hair fiber, creating the visual impression of increased diameter along the strand. Alongside nourishing agents, it smooths cuticles to improve light reflection and perceived fullness without coating hair with heavy build-up.

• Hyaluronic acid plumps fiber for fuller-looking strands
• Lightweight conditioning avoids weighing fine hair down
• Smoother cuticles improve shine and body

Will this conditioner detangle and strengthen fragile hair?

Yes — Densifique Densité functions as a detangler while delivering strengthening benefits to fragile fibers. It reduces friction during combing and adds moisture to restore elasticity, making hair easier to manage and less prone to breakage when styling.

• Detangles mid-lengths and ends for easier comb-through
• Moisturizes to improve flexibility and reduce snap
• Supports healthier-looking texture with regular use

How should I use it for best results?

Apply a quarter-size amount to wet hair after shampooing and distribute evenly through mid-lengths and ends. Leave the conditioner on for 2–3 minutes to let actives penetrate, then rinse thoroughly; use with other Densifique products for a complete regimen focused on density and texture.

• Apply to clean, wet hair after shampooing
• Leave on 2–3 minutes before rinsing
• Use consistently for improved texture and volume

Will it work with colored or chemically treated hair?

Formulated to be gentle on fragile fibers, this conditioner can be used on color-treated and chemically processed hair to add moisture and manageability. It focuses on improving surface texture and resilience without stripping color when used as directed.

• Suitable for color-treated and processed hair types
• Restores suppleness without heavy residue
• Pairs well with professional color-safe shampoos

Who is this for: KÉRASTASE Densifique Densité Conditioner is ideal for people with fine, thin or thinning hair who want weightless hydration, easier detangling and the appearance of fuller hair. It suits all hair types that lack density, including those with colored or chemically treated hair, and works best as part of a consistent Densifique routine for improved texture and volume.
