Kérastase Resistance Masque Extentioniste Length Strengthening Mask, 6.8 oz

Kérastase Resistance Masque Extentioniste is a deep-treatment hair mask designed to strengthen lengths and restore damaged mid-lengths and ends. Its fortifying formula supports healthier, more resilient hair, helping you preserve length as it grows instead of losing it to breakage and split ends.

Used weekly in place of conditioner, the rich masque nourishes intensely while leaving hair supple and easy to detangle. Lengths look smoother and feel noticeably stronger with continued use.

• Length-strengthening mask for growing hair
• Helps restore damaged lengths and seal ends
• Supports stronger, more resilient hair over time
• 6.8 oz jar

Complete the routine with Extentioniste bain and fondant for the full Kérastase length-care program.
