What you’ll experience

• Deepen the integrity of each strand to reduce breakage on longer lengths, so your hair feels sturdier over time

• A practical addition to a longer-hair routine, supporting gradual length retention as part of regular care

Why this matters for longer hair

• Damaged ends and slow growth are often tied to fiber weakness. By reinforcing the hair fiber with Creatine and sealing the cuticle with Maleic Acid, Fondant Extentioniste helps protect longer lengths from further breakage.
• Ceramide contributes to surface recovery, smoothing the hair’s outer layer so strands feel softer and look more uniform
• The result is more manageable, less tangled hair that retains length more effectively over time

Ideal for

• Anyone pursuing longer, healthier-looking hair who notices breakage or sluggish growth on mid-to-long lengths
• Regular users of the Kerastase Resistance Extentioniste routine seeking a dedicated length-strengthening conditioner

Incorporate Kerastase Resistance Fondant Extentioniste Length Strengthening Conditioner into your routine to support longer, more resilient lengths without compromising the softness and ease you expect from a premium conditioner.
