Kerastase Resistance Masque Extensioniste

Kérastase is a cult favourite in the haircare world, and for good reason – its scientifically formulated products help any hair type transform into a healthier, shinier incarnation. The Resistance Masque Extensioniste is the hair mask to reach for if your locks are damaged or brittle, thanks to creatine and maleic acid –ingredients that help repair bonds within the hair structure before sealing the cuticle to prevent further damage.
