Kostume Rio de Janeiro USA K. Fiber Repair Plex Protein S.O.S.
The emergency step — and the one you can mix straight into the service. This concentrated Brazilian bond treatment works where hair is most compromised, helping rebuild weakened strands, restore elasticity, and seal the cuticle. Use it at home after washing, or add it directly to bleach, color, or a mask to help protect the hair fiber while you work.
Made in Brazil, where humidity, sun, and salt make hair repair a daily science rather than a seasonal fix. The formula layers keratin, creatine, and wheat protein with aloe vera, linseed and castor oils, held in a tragacanth gum base that smooths as it hydrates.
[SENSORY LINE — one sentence on texture and scent. Example: "A lightweight, fast-absorbing serum with a clean [SCENT] finish — one to two pumps covers mid-lengths to ends." Replace with what's true.]
What it does
- Helps protect the hair fiber during bleaching and color services
- Helps rebuild and fortify weakened strands
- Helps restore elasticity to brittle, over-processed hair
- Helps seal the cuticle for a smoother, glossier finish
- Delivers deep hydration to dry, stressed hair
- Smooths frizz and improves manageability
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
- Wheat Protein — fills weak spots along the shaft and adds body
- Aloe Vera Extract — soothes and moisturizes hair and scalp
- Linseed Oil — omega-3 rich nourishment for shine and smoothness
Rounded out with castor oil, tragacanth gum, and pro-vitamin B5 panthenol.
Professional use — mix it into the service
Add 10 ml to your standard bleach mixture before lightening, to a color formula, or to a hair mask to help protect the hair fiber throughout the service. One bottle works across the backbar, which is what makes it a stylist favorite.
