Description
Kostume Rio de Janeiro USA K. Fiber Reconstructing Repair Conditioner
Revive and restore damaged hair. This salon-grade Brazilian conditioner works inside the hair fiber to help rebuild weakened strands, replenish moisture, and rebalance pH for a smooth, sealed cuticle.
Made in Brazil, where humidity, sun, and salt make hair repair a daily science rather than a seasonal fix. The formula pairs clinical proteins with mulateiro — an Amazonian bark extract prized locally for restoring worn hair — alongside avocado butter and cold-pressed argan and macadamia oils.
The texture is a dense, slow-melting cream with a soft finish — a coin-sized amount covers mid-lengths to ends."
What it does
- Helps rebuild and fortify weakened strands
- Helps reduce breakage and improve elasticity
- Delivers intense hydration to dry, treated hair
- Helps rebalance pH to seal the cuticle
- Smooths frizz and improves detangling for a polished, glossy finish
Key ingredients you'll love
- Hydrolyzed Keratin — replenishes natural protein to rebuild hair structure
- Creatine — fortifies the hair shaft for brittle, chemically treated hair
- Hyaluronic Acid — deeply hydrates hair and scalp, restoring elasticity
- Mulateiro Extract — antioxidant Amazonian bark extract that helps repair and revitalize
- Avocado Butter — fatty acids plus vitamins A, D, E and B6 for lasting softness
- Argan Oil — vitamin E and antioxidants for shine and smoothness
Rounded out with wheat protein, macadamia and castor oils, and pro-vitamin B5 panthenol.
