Leave on for 3-5 minutes as recommended by users for best absorption, then rinse completely. For optimal results, use nightly as part of your pre-sleep routine. Timeline Expectations: Week 1: Hair feels noticeably cleaner, softer, and easier to comb through after the first wash.

Week 4+: With consistent use, hair develops a healthier-looking shine and improved resilience, feeling stronger and less prone to breakage from daily styling.

Born from Kose's 70+ years of Japanese skincare science, this formula was created for a modern problem: hair that feels tired from daily stress, styling, and environmental damage. Our researchers in Tokyo developed the Midnight Repair complex to work with your body's natural overnight recovery cycle. Every ingredient is selected for a single purpose—to support hair's internal strength and external shine—and is manufactured in a GMP-certified facility in Japan, meeting strict Japanese pharmaceutical-grade standards. This trial set is the #1 best-selling hair treatment trial kit in its category in Japan, trusted by over 500,000 users who wanted to experience the results firsthand before committing.

The Kose Je l'aime Relax Midnight Repair Trial Set for Straight & Rich Hair incorporates a thoughtfully curated blend of ingredients designed to repair, nourish, and enhance hair health overnight. Key components include hydrolyzed silk protein, which strengthens hair fibers and reduces breakage by penetrating the cortex to improve elasticity and manageability. Ceramides are included to restore the hair's lipid barrier, locking in moisture and protecting against environmental damage for smoother, shinier strands. Botanical extracts such as camellia oil and argan oil provide deep conditioning, delivering essential fatty acids and antioxidants that combat dryness and frizz while promoting softness and luster. Amino acids like arginine and lysine support keratin structure, aiding in repair and reducing split ends. Additionally, panthenol (pro-vitamin B5) enhances moisture retention and adds volume, making hair appear fuller and more resilient. These ingredients work synergistically during the night to target damage from daily styling and environmental stressors, resulting in revitalized, straight, and rich-looking hair by morning.
