Why our stylists rate it
From the Partners Hair team
Kérastase Densifique Fondant Densité is a thickening conditioner for thin, fine, or thinning hair. Part of the Kérastase Densifique range — the brand's density and fullness system. Lightweight formula that plumps the fibre with Hyaluronic Acid and Intra-Cylane while preventing breakage, delivering body without weight.

Best for: fine, thin, or visibly thinning hair where fullness and texture are the priority; flat or limp hair that lacks substance after washing; the conditioning step in the Densifique routine paired with Bain Densité (shampoo) and Densimorphose Mousse (leave-in volumiser), or with the Cure Densifique vial program for clinical thinning support.
Less suited to: thick, coarse, or frizz-prone hair (use Kérastase Discipline — Fondant Fluidealiste or Oléo-Relax range); damaged hair primarily needing structural repair (use Resistance Ciment Anti-Usure); blonde, bleached, or colour-treated hair where colour care is the priority (use Blond Absolu Cicaflash or Chroma Absolu); dry, dehydrated hair (use Kérastase Nutritive — Fondant Magistral or Lait Vital).

Key actives:
- Hyaluronic Acid — ultra-concentrated humectant; plumps the fibre, hydrates, and strengthens to prevent future breakage; holds 1,000 times its weight in water
- Intra-Cylane® — Kérastase's patented filling molecule that penetrates the cortex and fills internal gaps in the hair structure, enhancing fibre integrity from within
- Ceramide R — lipid that reinforces the cuticle, smooths the surface, and protects against further fibre stress
- Gluco-Peptide — strengthens the fibre and restores uniformity to weakened lengths

Benefits:
- Visibly thickens individual hair fibres for fuller-looking hair
- Improves texture, body, and substance without weight
- Easily detangles fine hair without flattening it
- Strengthens hair to reduce breakage and improve resilience
- Lightweight finish — conditions without weighing thin hair down

How to use: Apply a quarter-sized amount to wet hair after shampooing with Bain Densité. Distribute evenly through mid-lengths and ends — avoid the roots. Leave on for 2–3 minutes. Rinse thoroughly. Follow with Densimorphose Mousse on damp hair for extra body.

Format: 200ml conditioner.
