Kerastase Resistance Masque Extentioniste Hair Mask - 200ml

Kerastase Resistance Masque Extentioniste Hair Mask is an intensive strengthening and restorative hair treatment specially formulated to nourish weak, brittle, and damaged hair while reducing breakage and supporting healthy length retention. Powered by Creatine R technology, it reinforces the internal structure of the hair fibre, improving strength, resilience, and elasticity from roots to ends. The formula contains Creatine to strengthen weakened hair strands, Ceramides to smooth the cuticle and improve moisture retention, and Maleic Acid to reinforce the hair fibre and reduce the appearance of split ends. Enriched with conditioning ingredients, including Cetearyl Alcohol and Amodimethicone, it softens hair, improves detangling, and enhances manageability without excessive heaviness. Its rich, nourishing texture deeply conditions damaged lengths, leaving hair smoother, shinier, and more resistant to mechanical breakage. Ideal for long, weakened, and damaged hair, Kerastase Resistance Masque Extentioniste supports stronger, healthier-looking lengths with regular use.
