Kose, a trusted name in Japanese skincare since 1946, created the Je l'aime Relax Midnight Repair line to solve a modern problem: hair damaged by daily stress, environmental pollution, and harsh styling. Their researchers in Tokyo developed this shampoo specifically for straight hair, focusing on overnight repair when the body's natural recovery is highest. They selected a patented amino acid complex and ceramide formula, tested in 8 clinical trials for efficacy and safety. Every batch is produced in a GMP-certified facility in Japan, adhering to strict pharmaceutical-grade standards. This commitment to precision has made it a top-ranked shampoo in its category for over 3 years in Japan, trusted by users who value visible results without compromise.

Kose Je l'aime Relax Midnight Repair Shampoo - Straight & Gloss 480ml contains a carefully formulated blend of ingredients designed to cleanse, repair, and enhance straight, glossy hair. Key components include water and sodium laureth sulfate as primary cleansing agents that gently remove impurities without excessive stripping. Silicone derivatives like dimethicone and amodimethicone are included to provide smoothness, reduce frizz, and impart a high-shine finish by coating the hair shaft. Botanical extracts such as hydrolyzed silk protein and royal jelly extract deliver reparative benefits by strengthening hair fibers and improving elasticity, while panthenol (pro-vitamin B5) adds moisture retention and softness. Additionally, fragrance and preservatives like methylparaben ensure product stability and a pleasant sensory experience. This combination aims to repair damage from daily styling, enhance straight hair's natural sleekness, and provide long-lasting gloss and manageability.
