1. After washing your hair, towel dry to remove excess water. 2. Apply an appropriate amount (about a cherry-sized dollop) evenly from mid-lengths to ends. 3. Do not rinse out. Style as usual. For best results, use nightly as the final step in your routine. Timeline Expectations: Week 1: Hair feels noticeably softer and easier to comb through after the first few uses.

Week 4+: With continued use, hair maintains a straighter, glossier appearance with improved resilience against heat and environmental stress.

Born from Kose's 70+ years of Japanese skincare science, this treatment was created for a modern problem: hair that feels tired from daily styling, stress, and environmental damage. The 'Midnight Repair' formula is designed to work while you sleep, using a targeted blend of ceramides and amino acids to support your hair's natural recovery cycle. Every batch is made in Japan under strict GMP (Good Manufacturing Practice) certification, ensuring pharmaceutical-grade quality. It's not just a treatment; it's a nightly ritual trusted by users across Japan for its straightforward, no-fuss approach to waking up to smoother, glossier hair that feels cared for, not just styled.

The Kose Je l'aime Relax Midnight Repair Hair Treatment - Straight & Gloss is formulated with a blend of targeted ingredients designed to repair, straighten, and enhance hair gloss. Key components include hydrolyzed keratin, which penetrates the hair shaft to strengthen and repair damage from heat styling or chemical treatments by replenishing protein loss. Silicones such as dimethicone and cyclopentasiloxane are included to coat the hair cuticle, providing immediate smoothness, reducing frizz, and enhancing shine by reflecting light. Botanical extracts like camellia sinensis leaf extract and argan oil offer antioxidant properties and moisturization, helping to nourish the scalp and hair while protecting against environmental stressors. Additionally, panthenol (pro-vitamin B5) acts as a humectant to retain moisture, improving hair elasticity and reducing breakage. Ceramides are incorporated to restore the hair's lipid barrier, locking in moisture and preventing further damage. This combination works synergistically to deliver deep repair overnight, promote straightening effects, and impart a long-lasting glossy finish, making it ideal for those seeking to rejuvenate and manage damaged or unruly hair.
