Hair That Feels Silky, Not Sticky

Users say it 'sinks right in without any weird residue.' The formula hydrates deeply so hair feels soft and light, never coated or heavy.

Tames Frizz for a Polished Look

Reviewers note 'even my flyaways lay flat' in humid weather. It smooths the hair cuticle to fight frizz and create a sleek, manageable finish.

Makes Detangling Effortless

'My comb glides right through' is a common sentiment. It significantly reduces knotting and breakage during brushing, especially for long or processed hair.

Adds a Visible, Healthy Shine

Customers report 'my hair has a glass-like shine' after a few weeks. It reflects light better by repairing the hair's surface for a glossy, healthy appearance.

Protects Hair From Daily Damage

It acts as a shield against 'blow-dryer heat and city pollution.' The treatment helps fortify hair to withstand common stressors that cause dryness.

Gives Hair Bounce and Body

Long-Lasting Smoothness Between Washes

The effects are durable, with reviews stating 'my hair stays smooth for days.' You maintain that just-treated softness and shine until your next wash.

Born from Kose's 70+ years of Japanese skincare science, this treatment was created for hair that feels tired from modern life—heat styling, pollution, and stress. Our labs in Tokyo saw that deep hydration was the missing key for lasting shine and softness, not just a surface fix. We selected a concentrated blend of ceramides and amino acids, identical to those in our award-winning face creams, to repair the hair's internal moisture barrier. Every batch is produced in a GMP-certified Japanese facility, adhering to the strictest quality controls. It's a formula trusted in salons across Japan, consistently ranking as a top-selling treatment for damaged hair because it delivers the glossy, manageable results professionals and their clients rely on.

The Kose Kirage Rich Moist Hair Treatment contains a carefully formulated blend of ingredients designed to provide deep hydration and repair for glossy, healthy-looking hair. Key components include hydrolyzed collagen, which penetrates the hair shaft to improve elasticity and reduce breakage, and ceramides that help restore the hair's natural lipid barrier to lock in moisture and enhance shine. Silicone derivatives like dimethicone create a smooth, protective coating on the hair cuticle, reducing frizz and adding slip for easier detangling. Botanical extracts such as camellia sinensis leaf extract and royal jelly extract deliver antioxidants and nourishing properties to strengthen hair and promote scalp health. Humectants like glycerin attract and retain moisture from the environment, ensuring long-lasting hydration. These ingredients work synergistically to repair damage from heat styling and environmental stressors, resulting in soft, manageable hair with enhanced gloss and reduced split ends.
