Kérastase Résistance Thermique Extentioniste – Length-Strengthening Heat Protectant for Growing Hair

Available in Canada at Curious Salons

For
Fragile, breakage-prone, or slow-growing hair that needs heat protection, smoothness, and strengthened lengths for healthy, consistent growth.

Description
A protective veil for your length-loving journey. Kérastase Résistance Thermique Extentioniste is a lightweight, strengthening blow-dry milk designed to shield fragile hair from heat while reinforcing the fibre for longer, smoother, more resilient lengths. Its silky texture melts into the hair, offering effortless detangling, frizz control, and lasting softness — without weight.

Infused with the powerful Creatine R™ Complex and Taurine, this leave-in treatment improves internal strength, reduces breakage, and supports a healthy scalp environment.
