Fights Frizz Caused by Humidity and Daily Stress

Helps shield hair from the drying effects of modern life—air conditioning, heating, and pollution—so it stays looking smooth, not 'puffy' or unruly.

Deep Nourishment Without Weighing Hair Down

The rich-but-light texture delivers intensive moisture where straight hair needs it most, without leaving any 'greasy' or 'heavy' feeling.

Supports Your Hair's Natural Overnight Recovery

Works with your body's rhythm to nourish while you rest, so you're actively caring for your hair even during sleep.

Saves Time in Your Morning Routine

By tackling dryness and frizz overnight, it can cut down on blow-drying and styling time, giving you 'ready-to-go' hair when you wake up.

Ideal for Sensitive Skin and Scalp

The fragrance-free, pH-balanced formula is gentle, with users noting it's 'good for sensitive skin' and causes 'no irritation'.

Helps Protect Hair from Daily Heat and Styling Damage

Forms a lightweight protective layer that can help minimize damage from next-day heat styling, keeping hair looking healthier.

Builds Long-Term Hair Resilience

With consistent use, it doesn't just fix today's dryness but helps improve your hair's overall condition, leading to 'stronger', more resilient strands over time.

1. After washing and towel-drying hair, apply an appropriate amount (about a cherry-sized dollop) evenly from mid-lengths to ends. 2. Do not rinse out. Style as usual and allow hair to dry. For best results, use nightly as part of your pre-sleep routine. Timeline Expectations: Week 1: Users often note hair feels 'smoother to the touch' and 'easier to comb' in the morning. Week 2-3: Cumulative nourishing effects become more noticeable; hair may appear 'less frizzy' and have 'more shine' throughout the day. Week 4+: With consistent use, the focus shifts to long-term resilience; hair can feel 'stronger', 'more manageable', and maintain a 'healthy-looking straight style' with less daily effort.

Born in Japan's Kose laboratories, this treatment was created for those whose modern lifestyle—late nights, stress, and environmental factors—can impact hair's natural vitality. Our researchers focused on a single goal: to support your hair's own overnight recovery process. Every ingredient is selected for a specific, documented role, sourced under Japan's strict Pharmaceutical Affairs Law. The formula is produced in a GMP-certified facility, the same standard used for medicines, ensuring every bottle meets exact purity and potency specifications.

Kose Je l'aime Relax Midnight Repair Treatment Straight & Rich is formulated with a blend of ingredients designed to repair and nourish hair overnight. Key components include hydrolyzed keratin, which penetrates the hair shaft to strengthen and restore elasticity by replenishing proteins lost through damage. Ceramides are incorporated to reinforce the hair's lipid barrier, locking in moisture and improving smoothness and shine. Argan oil provides essential fatty acids and antioxidants that condition the hair, reduce frizz, and protect against environmental stressors. Panthenol (pro-vitamin B5) acts as a humectant to attract and retain moisture, enhancing hair softness and manageability. Additionally, silk amino acids offer lightweight conditioning to improve texture and reduce breakage. These ingredients work synergistically to repair damage, enhance straightness, and deliver rich, long-lasting hydration, making the treatment ideal for revitalizing dry or chemically treated hair while users sleep.
