Born from Kose's 70+ years of Japanese skincare science, this overnight hair milk was created to solve a modern problem: hair damage from daily stress, styling, and environmental factors. Our researchers in Tokyo spent 3 years developing the Midnight Silk Repair formula, selecting 5 patented silk proteins and ceramides for their proven ability to mimic and repair the hair's natural lipid layer. Every batch is produced in a GMP-certified facility in Japan, adhering to strict pharmaceutical-grade standards. The formula underwent 7 clinical trials with 142 participants before launch. It quickly became a top-ranked overnight treatment in Japan, trusted by users for its 'no-sticky' feel and 'morning softness'.

Kose Je l'aime Relax Overnight Hair Care Milk - Midnight Silk Repair contains a blend of ingredients designed to nourish and repair hair overnight. Key components include hydrolyzed silk protein, which penetrates the hair shaft to strengthen and add elasticity, reducing breakage and improving manageability. Ceramides are included to restore the hair's lipid barrier, locking in moisture and enhancing shine while protecting against environmental damage. Argan oil provides deep conditioning with its rich fatty acids and vitamin E, smoothing frizz and adding softness. Panthenol (pro-vitamin B5) acts as a humectant to attract and retain moisture, promoting hydration and volume. Botanical extracts such as chamomile and lavender offer soothing properties and a calming fragrance, contributing to a relaxing nighttime experience. These ingredients work synergistically to repair damaged cuticles, improve hair texture, and deliver silky, revitalized results by morning.
