A lightweight, creamy fortifying conditioner specifically designed for fragile hair prone to breakage and shedding. This daily-use formula helps reinforce the hair fiber and improve resilience, particularly targeting mid-lengths and ends where damage is most common. The soft-touch texture delivers essential hydration and strength without weighing hair down, leaving strands supple, silky, and more resistant to daily stressors.

Perfect If You Have:

  • Fragile hair is prone to breakage and snapping
  • Hair weakened by heat styling or daily stress
  • Fine or thinning hair that needs strengthening without added weight
  • Hair is experiencing increased shedding (including postpartum periods)
  • Strands that feel weak, brittle, or lack resilience

Why You’ll Love It:

  • Strengthens hair fibre while maintaining a lightweight feel
  • Reduces breakage at vulnerable mid-lengths and ends
  • Provides hydration without heaviness or greasiness
  • Creates smoother, more manageable hair with every use
  • Works as part of a complete strengthening system when paired with Genesis shampoo and serum
  • Ideal daily defence for hair that needs support, not weight

Key Ingredients:

  • Edelweiss Native Cells – Antioxidant-rich extract that helps protect against daily aggressors and preserves hair fibre strength
  • Ginger Root – Stimulating ingredient that promotes hair resistance, provides protective benefits against external stressors, and supports hydration

Pomme Pro Tip:

Apply mid-lengths to ends on towel-dried hair after shampooing – your roots don’t need the extra conditioning! Leave for 2-3 minutes while you do your skincare routine, then rinse thoroughly. For maximum strengthening power, pair with Genesis Bain Hydra-Fortifiant shampoo and finish with a few drops of Genesis Anti Hair-Fall Serum on damp lengths. Your hair will thank you for the TLC!

    1. Start Clean - After shampooing with Genesis Bain Hydra-Fortifiant (or your preferred shampoo), gently squeeze excess water from hair
    2. Apply Strategically - Take a generous amount and apply from mid-lengths to ends, avoiding the roots and scalp area
    3. Work It Through - Use a wide-tooth comb or your fingers to distribute evenly through damp hair
    4. Let It Work - Leave on for 2-3 minutes to allow the fortifying ingredients to penetrate the hair fibre
    5. Rinse Thoroughly - Rinse completely with lukewarm water until hair feels clean and product-free
    6. Finish Strong - For best results, follow with Genesis Anti Hair-Fall Serum on towel-dried lengths

    Frequency: Use after every shampoo as part of your regular hair care routine. Safe for daily use on fragile or weakened hair.

  • 1. Will this conditioner weigh down my fine/thin hair?
     No! Genesis Fondant is specifically formulated with a lightweight texture that strengthens without adding heaviness. It's perfect for fine or fragile hair that needs fortification but can't handle rich, heavy conditioners.

    2. Can I use this if I'm experiencing postpartum hair loss?
     While this isn't a treatment for postpartum hair loss itself, it's excellent for minimizing breakage during periods of increased shedding. Many clients pair it with the Genesis system to support hair strength during postpartum recovery.

    3. How often should I use this conditioner?
     You can use Genesis Fondant after every shampoo as part of your regular routine. It's gentle enough for daily use and designed to build strength with consistent application.

    4. Do I need to use the entire Genesis system, or can I use this alone?
     While it works beautifully on its own, you'll see maximum results when paired with Genesis Bain Hydra-Fortifiant shampoo and Genesis Anti Hair-Fall Serum for a complete strengthening system.

    5. How long should I leave it on my hair?
     Leave Genesis Fondant on for 2-3 minutes to allow the strengthening ingredients to penetrate the hair fibre, then rinse thoroughly.

    6. Can I use this on colour-treated or chemically processed hair?
     Yes! This gentle, fortifying formula is safe for colour-treated, highlighted, or chemically processed hair and can actually help strengthen hair weakened by chemical services.

    7. What's the difference between this and a regular conditioner?
     Unlike regular conditioners that just provide moisture, Genesis Fondant contains fortifying ingredients like Edelweiss Native Cells and Ginger Root that actively strengthen the hair fibre and improve resistance to breakage over time.
