Kérastase Spécifique Bain Prevention is a scalp-care shampoo for hair that's thinning or prone to it. Its patented anti-thinning complex and amino acids work at the root — purifying the scalp without stripping and reinforcing hair at its base — so hair grows in stronger, fuller-looking and more resilient over time.

Benefits
  • Targets thinning at the root — a patented anti-thinning complex works at the scalp.
  • Fuller-looking hair — supports stronger, denser-looking regrowth over time.
  • Scalp balance — reduces excess sebum without stripping the scalp.
  • Gentle daily care — amino acids strengthen the fibre, suitable for everyday use.
How to use
  1. Apply to wet hair, concentrating on the scalp and roots.
  2. Massage with fingertips for about 60 seconds to activate at the root, then work through the lengths.
  3. Rinse, and repeat if needed. Use daily or 3–4 times a week.
Who it's for

Why our stylists rate it
From the Partners Hair team
Kérastase Spécifique Bain Prevention is a fortifying shampoo for hair prone to thinning. Part of the Kérastase Spécifique scalp care range. Boosts scalp microcirculation while thickening and strengthening the hair fibre.

Best for: hair showing visible signs of thinning, density loss, or shedding; daily prevention of hair fall in scalps prone to weakness; the cleansing step in a Spécifique anti-hair-loss routine paired with Stimuliste spray or Cure Anti-Chute treatment.
Less suited to: hair with severe active hair fall needing intensive treatment (combine with Spécifique Stimuliste leave-in spray or Cure Anti-Chute ampoule treatment); hair primarily concerned with density rather than fall (use Densifique Bain Densité or Bain Densité Homme); sensitive or irritated scalps (use Spécifique Bain Vital Dermo-Calm); colour-treated hair where colour care is the priority (use Chroma Absolu or Blond Absolu).

Key actives:
- Systeme Pro-Actif technology — Kérastase's signature scalp-stimulating complex that supports microcirculation and protein absorption at the root
- Soothing scalp agents — calm and condition the scalp environment
- Anti-bacterial agents — support scalp hygiene during the cleansing step
- Lightweight cleansing base — gentle enough for frequent use

Benefits:
- Designed to help prevent visible hair thinning with consistent use
- Boosts scalp microcirculation through recommended massage application
- Adds texture and visible volume to fine, thinning hair
- Supports a stronger, healthier scalp environment
- Suitable for frequent use as part of a daily anti-hair-loss routine

How to use: Apply to damp hair. Emulsify and massage thoroughly into the scalp using fingertips and circular motions to activate micro-circulation. Rinse. Use frequently for best results. For an intensified routine, follow with Spécifique Stimuliste leave-in spray or Cure Anti-Chute ampoule treatment.

Format: 250ml shampoo. Also available in 500ml professional/salon size.

Before you buy
Common questions

What is the difference between Kérastase Spécifique and Densifique?

Spécifique Bain Prevention works at the scalp root to target the cause of thinning — proactive and preventative. Densifique works at the hair-fibre level to plump and add visible density to existing hair. Used together, they address thinning from both angles.

Can I use Bain Prevention every day?

Yes — the gentle formula is designed for daily use, and the more consistently it's used, the better the results over time.

How long before I see results with Bain Prevention?

Most people notice improved scalp feel and hair strength within 4–6 weeks of daily use. Fuller-looking results develop over 2–3 months with consistent use.

Is Spécifique suitable for men?

Yes — it suits all hair types, men and women, and works equally well on male-pattern thinning and general thinning.

Does Bain Prevention stop hair loss?

It's designed to prevent further thinning and support a healthier scalp for stronger hair. It isn't a medical hair-loss treatment, but a cosmetic formula that visibly improves the appearance of thinning hair.
