K\u00e9rastase Resistance Strengthening Conditioner is a replenishing conditioner formulated with amino acids to strengthen damaged hair lengths and seal split ends, making hair visibly longer. It is suitable for fine, medium, and thick hair types, as well as straight, wavy, curly, and coily hair textures. It addresses concerns such as damage, split ends, breakage, dryness, and shine. Key benefits include strengthening damaged lengths for visibly longer hair, sealing cuticles for protection from root to tip, and detangling while sealing split ends. The formula contains a complex called Creatine-R (amino acids to reinforce hair fiber structure), Maleic Acid (penetrates and seals hair strands), and Ceramides (strengthen hair, enhance shine and moisture). The conditioning product is creamy and recommended by stylists for intense fortifying care that increases shine and protects hair. Usage involves applying after shampooing, massaging through mid-lengths and ends, leaving for 2-3 minutes, and rinsing thoroughly. Available size: 6.8 oz / 200 mL. Price is $50 with a 5% off option of $47.50 by enrolling in Auto-Replenish at Sephora.
