A fortifying shampoo designed for normal to dry, weakened hair that is prone to falling due to breakage from brushing. This nourishing formula gently clarifies hair while restoring moisture for enhanced fibre retention and minimized hair fall. When activated with water, it transforms into a creamy lather that helps retain moisture and remove oils and bacteria while providing intense nourishment and gently detangling hair.  Perfect for those with dry, thirsty strands that need both strengthening and deep hydration.

Perfect If You Have:

  • Thick or dry hair that needs extra moisture
  • Normal to dry, weakened hair is prone to breakage from brushing
  • Hair that feels rough, tangled, or difficult to manage
  • Dry scalp that needs gentle cleansing with added nourishment
  • Strands that break easily and need both moisture and strength
  • Hair that lacks softness and smoothness after washing

Why You’ll Love It:

  • Gently cleanses scalp and hair while adding essential moisture
  • Provides intense nourishment and gently detangles hair
  • Prevents the risk of hair fall due to breakage from brushing
  • Increases strength and softness with every wash
  • Gentle enough to be used daily
  • Creates a rich, creamy lather that feels luxurious and nourishing

Key Ingredients:

  • Edelweiss Native Cells – Detangle, moisturize, and increase strength while boosting elasticity
  • Ginger Root – Detangles, moisturizes, and increases strength and softness while delivering anti-inflammatory benefits to calm the scalp

Pomme Pro Tip:

This is your thirsty hair’s best friend! The creamy lather feels so luxurious – take your time massaging it through your scalp for that spa-like experience. Since it’s super concentrated, resist the urge to use more – that coin-size amount will surprise you with how much lather it creates! For extra dry hair, follow with the Genesis Masque once a week instead of the Fondant. Your hair will drink up all that moisture!

  • 1. What's the difference between this and the Genesis Bain Hydra-Fortifiant?
     Bain Nutri-Fortifiant is meant for thick or dry hair, whereas Bain Hydra-Fortifiant is meant for fine or oily hair. The Nutri version provides deep moisture for dry hair, while the Hydra version controls oil for fine/oily hair.

    2. Can I use this if my hair is oily at the roots but dry at the ends?
     If your lengths are very dry, this could work, but you might prefer the Hydra version for better oil control at the roots. Consider alternating between both depending on your hair's daily needs.

    3. How much should I use for each wash?
     Just a coin-size amount - Kérastase is highly concentrated, so a little goes a long way.  You'll be surprised how much rich lather this small amount creates!

    4. Is this safe for colour-treated or chemically processed hair?
     Absolutely! This gentle, nourishing formula is perfect for hair that's been weakened by chemical processing and needs extra moisture and strength.

    5. Can I use this every day?
     Yes, this shampoo is gentle enough to be used daily and is designed to be your regular strengthening and moisturizing shampoo.

    6. Do I need to use a separate detangling product?
     This shampoo provides intense nourishment and gently detangles hair, but for very tangled hair, follow with Genesis Fondant or Masque for even easier combing.

    7. Will this weigh down my fine hair if it's also dry?
     If you have fine but dry hair, you might want to try the Hydra version first, or use this one just on your mid-lengths and ends while using a lighter shampoo on your roots.
