Kérastase Densifique Masque Densité is a weekly densifying mask for medium to coarse thinning hair. Using Densifique technology and hyaluronic acid, it plumps each fibre from root to tip — restoring body, bounce and resilience for visibly thicker, fuller hair you feel from the first use.

Benefits
  • Visibly fuller hair — Densifique technology plumps the fibre for lasting thickness.
  • Restored body — brings back bounce to flat, thinning hair.
  • Deep hydration — hyaluronic acid softens without heaviness.
  • Stronger strands — reinforces the fibre to reduce breakage.
How to use
  1. After shampooing, squeeze out excess water and apply to mid-lengths and ends, avoiding the scalp.
  2. Leave 5–10 minutes.
  3. Rinse thoroughly. Use once or twice a week in place of conditioner.

From the Partners Hair team
Kérastase Densifique Masque Densité is a weekly densifying hair mask for medium-to-coarse hair losing density. Part of the Kérastase Densifique range. Intensive treatment that hydrates, plumps, and restores resilience to the hair fibre.

Best for: medium to coarse hair experiencing loss of density; hair that feels limp, deflated, or visibly thinner than before; the weekly intensive treatment step in a Densifique routine paired with Bain Densité and Fondant Densité.
Less suited to: very fine hair that may be weighed down (use Fondant Densité conditioner alone, or alternate this mask less frequently); hair primarily damaged by breakage rather than density loss (use Resistance Masque Extentioniste or Force Architecte); severely damaged hair (use Resistance Masque Thérapiste); colour-treated blonde hair (use Blond Absolu Cicaflash or Cicaextreme).

Key actives:
- Hyaluronic Acid (Sodium Hyaluronate) — retains up to 1000x its weight in moisture; hydrates and gives resilience and plumpness to the hair
- Gluco-Peptide — penetrates the deepest layers of the cuticle to compensate for surface irregularities and restore uniformity
- Stemoxydine® — Kérastase's signature density active that mimics the stem cell environment and helps awaken dormant follicles
- Intra-Cyclane — strengthens and protects the hair fibre
- Rich conditioning base — for deeper penetration into medium-to-coarse hair

Benefits:
- Hydrates and plumps the hair fibre for visible density and resilience
- Texturises and gives substance, body, and strength to thinning hair
- Compensates surface irregularities and restores uniformity from root to tip
- Leaves hair regenerated, smooth, and lightweight
- Suitable for medium to coarse textures where lighter treatments aren't enough

How to use: Apply to clean, towel-dried hair starting 2–3 cm from the roots. Massage onto lengths and ends. Leave on for 3–5 minutes. Emulsify and rinse thoroughly. Use weekly, or as needed, in place of Fondant Densité for deeper densifying treatment.

Format: 200ml mask.

Before you buy
Common questions

What does the Kérastase Densifique mask do?

It plumps each hair fibre using Densifique technology to create the appearance of greater thickness and fullness. Hair feels thicker after the first use and becomes progressively stronger with regular use.

How often should I use the Densifique mask?

Once or twice a week. Replace your regular conditioner with the mask on those days for the best density results.

What is the difference between the Densifique shampoo and mask?

The shampoo (Bain Densité) gives daily density support during cleansing. The mask is a deeper, more intensive weekly treatment — use both together for maximum results.

Is the Densifique mask suitable for fine hair?

It works best on medium to coarse thinning hair. For fine thinning hair, the Bain Densité shampoo used daily with the Fondant Densité conditioner may suit better, as the mask can feel heavy on very fine hair.

Can I use the Densifique mask on colour-treated hair?

Yes — the formula is safe for colour-treated and chemically processed hair. It conditions and strengthens without affecting colour.
