Stop fighting with morning tangles. This treatment works while you sleep, so you wake up to hair that feels "silky smooth" and combs through effortlessly, saving you time and frustration.

See a Visible Reduction in Frizz & Flyaways

Tame the chaos. By deeply nourishing the hair shaft, it helps seal the cuticle. Users love the "sleek look" and say it "calms frizz" without any greasy residue.

Strengthen Hair to Resist Daily Breakage

Fight back against the damage from styling, pollution, and stress. The amino acids help rebuild internal structure, leading to hair that feels "stronger" and snaps less during brushing.

Get Healthier-Looking Shine Without Oils

Achieve luminous shine from health, not coating. Reviews mention a "natural gloss" and "healthy sheen" that comes from within, not from heavy silicone layers.

Drastically Cut Down Your Morning Routine

Optimize your night. Applying this takes 60 seconds. You save precious morning minutes because your hair is already prepped, looking "presentable faster."

Experience a Calming, Spa-Like Bedtime Ritual

Turn repair into relaxation. The subtle lavender-chamomile scent is designed to help you unwind. Many say it's a "calming part" of their nightly wind-down.

Protect Your Hair's Length from Age & Stress

Hair quality can change with time and lifestyle. This treatment helps offset those external factors, supporting the hair's vitality so it looks and feels its best.

YOLU was founded in Osaka, Japan, by a team of cosmetic chemists frustrated with the cycle of daily damage and repair. They saw that modern life—heat styling, pollution, and stress—was constantly attacking hair, and typical treatments only worked on the surface. Their mission was to create a true overnight repair system. They developed this formula using a patented Japanese amino acid complex, selected for its proven ability to penetrate the hair cortex during sleep. Every batch is produced in a GMP-certified facility in Japan, adhering to strict pharmaceutical-grade standards. It has been clinically tested in 3 separate trials for efficacy and safety. Since its launch, it has consistently ranked as a top-selling overnight hair treatment in its category in Japan, trusted by users for its no-fuss, deep-repair approach.

The YOLU Calm Night Repair Hair Treatment 440g is formulated with a blend of targeted ingredients designed to repair and rejuvenate hair overnight. Key components include hydrolyzed keratin, which penetrates the hair shaft to strengthen and rebuild damaged protein structures, reducing breakage and improving elasticity. Argan oil is incorporated for its rich fatty acids and vitamin E, providing deep hydration, enhancing shine, and protecting against environmental stressors. Panthenol (pro-vitamin B5) acts as a humectant to attract and retain moisture, promoting softness and manageability. Niacinamide (vitamin B3) supports scalp health and improves blood circulation to follicles, potentially aiding in hair vitality. Additionally, silk amino acids smooth the cuticle layer, reducing frizz and imparting a silky texture. These ingredients work synergistically to repair damage from heat styling, chemical treatments, and daily wear, offering benefits such as restored strength, enhanced moisture retention, reduced split ends, and overall healthier-looking hair with regular overnight use.
