Hair That Combs Like Silk

Users say 'it glides right through' without pulling. The formula smooths the hair cuticle so your comb meets zero resistance, reducing breakage from daily detangling.

Frizz Vanishes, Even in Humidity

Real reviews note 'frizz is gone' and hair 'stays smooth all day.' The protective layer seals the cuticle to block out moisture in the air that causes puffiness.

Get That 'Just Left the Salon' Smoothness

Achieve that professionally straightened, glossy look without the flat-iron. Customers report hair looks 'polished' and 'has a beautiful shine' with regular use.

Lightweight Feel, No Greasy Residue

Unlike heavy conditioners that coat hair, this rinses completely clean. Your hair feels 'soft but not weighed down' and 'has more movement.'

Protects Hair From Your Daily Styling

Blame heat tools and brushing for damage. This acts as a shield, so your hair can withstand your routine and still feel 'healthy and strong.'

Smooths Rough, Brittle Ends Instantly

Targets the most damaged parts first. Users with dry ends say it 'makes them feel soft again' after just one wash, stopping split ends from getting worse.

Makes Hair Manageable and Easy to Style

Tames unruly hair so it 'does what you want.' You'll spend less time fighting with your hair in the morning and more time enjoying it.

A Simple Step for Consistently Better Hair

It's not a complicated treatment. Just swap your regular conditioner for this one to upgrade your hair's texture, health, and appearance over time.

1. After shampooing, squeeze excess water from your hair. 2. Apply a generous amount (about a cherry-sized dollop for shoulder-length hair) from mid-lengths to ends. 3. Gently comb through with your fingers to distribute evenly. Avoid the scalp. 4. Leave on for 2-3 minutes as recommended by users for deep penetration. 5. Rinse thoroughly with lukewarm water. Timeline Expectations: Week 1: Hair feels noticeably softer and easier to comb through after the first use, with less tugging and breakage. Week 2-3: With consistent use, hair develops a smoother, silkier texture. Frizz and flyaways become more manageable, and hair feels lighter. Week 4+: Hair maintains a visibly straighter, polished appearance with enhanced shine. The protective layer helps hair resist daily damage, keeping it feeling healthy and strong.

Born from Kose's 70+ years of Japanese skincare science, this conditioner was created for a modern problem: hair that feels rough and unmanageable from daily styling, stress, and environmental factors. Kose's researchers in Tokyo developed the Bioliss Pure Retouch line to target this specific frustration, formulating it with a patented silky straight complex to smooth the hair's surface. Every batch is manufactured in Japan under strict GMP-certified facilities, ensuring pharmaceutical-grade purity and consistency. The formula's effectiveness is backed by in-house clinical testing on Japanese hair types, making it a top-ranked choice in Japan's competitive haircare market for achieving salon-like smoothness at home.

The Kose Bioliss Pure Retouch Silky Straight Conditioner contains a blend of ingredients designed to smooth, hydrate, and protect hair. Key components include water as the base solvent, cetyl alcohol and stearyl alcohol as emollients and thickeners that provide a creamy texture and help smooth the hair cuticle for reduced frizz. Behentrimonium chloride acts as a cationic surfactant to detangle and improve manageability by depositing on damaged hair strands. Dimethicone, a silicone derivative, forms a protective film to seal in moisture, enhance shine, and reduce static and flyaways. Glycerin serves as a humectant to attract and retain moisture, promoting hydration and softness. Panthenol (provitamin B5) penetrates the hair shaft to strengthen and add elasticity, while hydrolyzed silk protein helps repair damage and improve smoothness. Fragrance is included for sensory appeal, and preservatives like methylparaben ensure product stability. Together, these ingredients work synergistically to deliver straight, silky hair with enhanced manageability, reduced breakage, and long-lasting hydration, making it ideal for those seeking frizz control and a polished finish.
