1. **Patented Midnight Repair Complex** — Features Kose's exclusive amino acid blend (including Silk Amino Acids) designed to penetrate and repair the hair cuticle during the night's natural restoration cycle. 2. **Straight & Rich Formula** — Specifically engineered for straight to slightly wavy hair that lacks volume, using lightweight polymers that add body without residue. 3. **Japanese Silk Protein** — Derived from ethically sourced silk, this ingredient provides a smooth, slip-like texture that mimics healthy hair. 4. **Amino Acid-Based Cleansing** — Uses gentle amino acid surfactants (like Sodium Cocoyl Glutamate) with a pH of 5.5 to clean without stripping natural oils. 5. **No Sulfates (SLS/SLES)** — Formula is free from harsh sulfates, sodium chloride, and synthetic colors to prevent irritation and dryness. 6. **Ceramide Precursor** — Contains Phytosphingosine to help support the hair's natural lipid barrier, improving moisture retention. 7. **GMP-Certified Manufacturing** — Produced in a Japanese facility certified for Good Manufacturing Practices, ensuring batch-to-batch purity and consistency. 8. **Dermatologist-Tested** — Clinically tested for safety on skin and scalp under the supervision of board-certified dermatologists in Japan. 9. **Weightless Volume Technology** — Uses a precise blend of hydrolyzed wheat protein and panthenol to lift roots without stiffness or stickiness. 10. **Rich, Luxurious Lather** — Despite being sulfate-free, it creates a dense, creamy foam that users describe as 'feels like a salon treatment.' 11. **Subtle, Clean Fragrance** — A light, fresh herbal-musk scent derived from natural essential oils that doesn't linger heavily or clash with perfumes.

1. Wet hair thoroughly with warm water. 2. Dispense a coin-sized amount (about the size of a 10-yen coin) into your palm. 3. Lather gently onto your scalp, then work through to the ends. 4. Massage your scalp for 60 seconds to activate the amino acids. 5. Rinse completely with cool water for added shine. For best results, follow with the matching conditioner. Timeline Expectations: Week 1: Hair feels cleaner, lighter, and easier to detangle right after the first wash. Week 2-3: You'll notice less frizz and a smoother texture throughout the day. Your hair starts to feel 'bouncier' at the roots. Week 4+: With consistent use, hair maintains a straight, rich appearance with weightless volume. It feels stronger, looks shinier, and manages better between washes.

Born from Kose's 75-year legacy in Japanese skincare science, this shampoo was developed for a specific need: hair that feels weighed down by modern life. Kose researchers in Tokyo noticed that stress, hard water, and daily styling were creating hair that looked flat and felt rough, even after washing. They formulated Je l'aime Relax Midnight Repair to work while you sleep, using a patented amino acid complex derived from Japanese silk protein. Every batch is produced in a GMP-certified facility in Japan, adhering to the same strict quality standards as their skincare. It's not just a shampoo; it's a targeted repair treatment that has become a top-ranked choice in Japan for straight, fine hair types seeking weightless volume and smoothness.

Kose Je l'aime Relax Midnight Repair Shampoo - Straight & Rich 480ml is formulated with a blend of ingredients designed to cleanse, repair, and nourish straight hair types. Key components include water and sodium laureth sulfate as primary cleansing agents that gently remove impurities without excessive stripping. Betaine acts as a mild surfactant and humectant to enhance foam quality and retain moisture. Silicone derivatives like dimethicone and amodimethicone are included to provide smoothness, reduce frizz, and improve manageability by coating the hair shaft. Hydrolyzed silk protein and ceramide NP contribute to strengthening and repairing damaged hair cuticles, enhancing elasticity and reducing breakage. Botanical extracts such as rosemary leaf extract and chamomile flower extract offer antioxidant and soothing properties, promoting scalp health. Additionally, panthenol (pro-vitamin B5) acts as a moisturizer to improve hair softness and shine, while fragrance and preservatives like methylparaben ensure product stability and a pleasant user experience. This combination aims to deliver deep repair, enhanced straightness, and long-lasting hydration for healthier-looking hair.
