Genesis Bain Nutri Fortifiant Shampoo by Kerastase

Kérastase Genesis Bain Nutri-Fortifiant Shampoo

A nourishing, strengthening shampoo for dry, weakened hair prone to breakage and shedding. Bain Nutri-Fortifiant cleanses gently while fortifying the hair fibre from root to tip — leaving hair stronger, softer, and noticeably more resilient with every wash.

Who It’s For

For dry, brittle, or breakage-prone hair that sheds excessively during brushing or styling. Ideal for anyone wanting to strengthen weakened hair while restoring moisture and softness.

What It Does

• Strengthens and fortifies the hair fibre from within
• Reduces breakage and excessive shedding
• Nourishes and hydrates dry, brittle hair
• Gently cleanses without stripping moisture
• Leaves hair softer, smoother, and more resilient

Why You’ll Love It

Because it turns your daily wash into a strengthening ritual. Hair feels noticeably more robust after just a few uses — less breakage in the brush, more confidence in every style. The perfect foundation for the full Genesis routine.

How to Use

1. Apply to wet hair and massage gently into the scalp
2. Work lather through lengths
3. Rinse thoroughly
4. Follow with Genesis Fondant Renforçateur or Masque Reconstituant
