Perfect If You Have:

  • Weak and or fragile hair that breaks easily at the ends
  • Hair that struggles to grow past a certain length due to breakage
  • Dry, damaged, or chemically treated strands needing repair
  • Fine hair that needs conditioning without heaviness or buildup

  • Effortless detangling – Turns knots and tangles into silky, manageable strands

  • Protects your lengths – Helps prevent split ends and keeps hair looking healthy

Key Ingredients:

  • Creatine R Complex – Penetrates deep to rebuild and fortify weakened hair structure
  • Ceramides – Seal the cuticle and restore the hair’s protective barrier for lasting shine
  • Glucids – Provide essential nutrients to strengthen hair fibre and improve elasticity

Pomme Pro Tip:

    1. How often should I use Fondant Extentioniste?
      Use 2-3 times per week or after every shampoo, depending on your hair's condition. If your hair is severely damaged, you can use it daily until it improves, then reduce frequency.
    2.  Where exactly should I apply this conditioner?
      Apply from mid-lengths to ends, avoiding the roots and scalp area. Focus on the areas where your hair is most prone to breakage - typically the oldest parts of your hair.
    3. Will this weigh down my fine hair?
      No, the lightweight formula is specifically designed for fine, fragile hair. It strengthens without adding weight or causing buildup. Start with a smaller amount and adjust as needed.
    4. What's the difference between this and regular conditioners?
      This is a strengthening treatment conditioner with Creatine R Complex that rebuilds hair structure, unlike regular conditioners that only provide surface smoothing. It's specifically formulated to prevent breakage and support length retention.
    5. Is this suitable for colour-treated or chemically processed hair?
      Absolutely! This conditioner is ideal for hair weakened by colouring, bleaching, or chemical treatments. It helps repair damage while protecting your colour investment.
    6. How do I know if this conditioner is working?
      Within 2-4 weeks of consistent use, you'll see reduced hair in your brush, less breakage when styling, and smoother, stronger-feeling hair overall.
