When hair starts to feel weak, thin, or more prone to snapping, whether from daily stress, heat styling, or major life shifts like postpartum recovery, building strength without weighing it down is key. Kérastase Genesis Fondant Renforçateur is a lightweight, creamy conditioner that helps reinforce the hair fibre and improve resilience where it matters most: mid-lengths and ends.

While not a treatment for postpartum hair loss, this formula is often paired with the Genesis Shampoo and Genesis Serum during periods of increased shedding to help minimize breakage and support naturally stronger, smoother strands. It delivers hydration and strength in a soft-touch texture that leaves hair supple, silky, and more resistant with every use.

Key Ingredients: 

  • Aminexil 1.5%:  Helps prevent collagen hardening around hair follicles to maintain strong hair anchorage and reduce breakage
  • Edelweiss Native Cells: A powerful antioxidant that protects hair fibres from environmental damage while enhancing softness and resilience
  • Ginger Root Extract: Supports scalp health by soothing irritation and defending against external aggressors, promoting a balanced environment for healthy hair growth

Why You’ll Love It

  • Lightweight, creamy texture that melts into fragile hair
  • Helps reduce hair fall from brushing and breakage
  • Improves manageability and detangles effortlessly
  • Enhances softness, shine, and resilience
  • Ideal for fine or weakened hair that needs daily strengthening

Pomme Pro Tip:
Think of this conditioner as your daily defence! Perfect when your hair needs support, not weight. Pair with Bain Hydra-Fortifiant and the Anti Hair-Fall Serum for a strand-strengthening system that supports long-term hair health.

    1. Will this weigh down fine hair?
      Not at all. Its fluid, creamy texture is designed to condition and strengthen without heaviness—perfect for finer hair types.
    2. Can I use this if I’m experiencing shedding or thinning?
      Yes, while this conditioner is not a treatment for thinning or postpartum loss, it’s commonly used as part of a breakage-prevention routine during periods of shedding. If you’re unsure about your specific hair needs, we recommend checking with a healthcare provider.
    3. Do I need to use the matching shampoo?
      Using it alongside Bain Hydra-Fortifiant ensures your hair gets reinforcing benefits from root to tip, but it can be used with other strengthening shampoos too.
