Keravis Multi-Action Hair Strengthening Protein – 1KG – Hydrolyzed Vegetable Protein

Keravis™ Multi-Action Hair Strengthening Protein – 1KG – Premium Hair Strengthening & Anti-Breakage Active – Hydrolyzed Vegetable Protein – Multi Action Hair Strengthening Active – Water Soluble

Quick Overview

Keravis™ is Croda’s premium multi-action peptide hair strengthening active, specifically designed to repair, reinforce, and protect damaged hair. Using advanced peptide-silane technology, Keravis™ penetrates deep into the hair cortex to strengthen hair internally while simultaneously forming a protective film over the cuticle to reduce friction and breakage.

Clinically tested and salon validated, Keravis™ improves hair strength, elasticity, flexibility, and resistance to everyday damage caused by heat styling, bleaching, coloring, chemical treatments, UV exposure, and repeated brushing. Suitable for both rinse-off and leave-in formulations, it is an ideal ingredient for premium shampoos, conditioners, hair masks, serums, and professional salon treatments.

Description

Healthy hair depends on strong internal protein structures and a well-protected cuticle. Daily exposure to heat styling, bleaching, coloring, chemical treatments, environmental pollution, UV radiation, and mechanical stress gradually weakens these structures, making hair dry, brittle, rough, and more susceptible to breakage.

Keravis™ has been developed to address these challenges through an innovative multi-action peptide-silane complex that strengthens hair both internally and externally.

Unlike ordinary conditioning proteins that primarily coat the hair surface, Keravis™ delivers a unique dual-action mechanism. Low molecular weight peptide components penetrate deep into the hair cortex, increasing moisture retention, improving flexibility, and reinforcing internal protein structures through hydrogen and covalent bonding. At the same time, higher molecular weight components remain on the hair surface, forming a lightweight protective film that lubricates and reinforces the cuticle, helping reduce friction, mechanical damage, and future breakage.

This comprehensive strengthening approach provides long-lasting protection against everyday wear and tear while visibly improving the appearance, feel, and manageability of the hair.

Keravis™ has been extensively evaluated using laboratory testing, fluorescence microscopy, radiolabelling studies, cyclic fatigue testing, flexabrasion testing, repetitive combing evaluations, and professional salon studies. These independent evaluations consistently demonstrate that Keravis™ significantly improves hair strength, reduces breakage, increases resistance to grooming damage, and enhances overall hair condition.

Suitable for both professional formulators and premium cosmetic manufacturers, Keravis™ is compatible with a wide range of surfactant systems, conditioning ingredients, silicones, proteins, and botanical extracts, making it an excellent choice for modern hair repair formulations.

Clinical Performance

Keravis™ has been scientifically validated through multiple laboratory studies and salon evaluations, demonstrating exceptional improvements in hair strength and resistance to breakage.

Up to 87% Less Hair Breakage

Professional salon evaluation on damaged Type 2 hair demonstrated that regular use of shampoo containing 2% Keravis™ together with conditioner containing 3% Keravis™ reduced hair breakage by up to 87% after 42 days compared with untreated formulations.

62% Longer Hair Lifetime

Cyclic fatigue testing confirmed that Keravis™ increased the characteristic lifetime of damaged hair by 62%, allowing hair fibers to withstand significantly more bending and mechanical stress before breaking.

53% Greater Resistance to Combing Damage

Independent repetitive combing studies demonstrated that Keravis™ improved resistance to combing damage by 53%, helping protect hair during everyday brushing and styling.

Up to 115% Improvement in Hair Strength

Flexabrasion testing showed substantial improvements in hair strength:

• 26% higher hair strength from shampoo formulations containing Keravis™
• 115% higher hair strength from conditioner formulations containing Keravis™

These results demonstrate Keravis™’s excellent ability to reinforce damaged hair fibers.

Up to 90% Consumer Satisfaction

Salon participants reported visible improvements in overall hair condition, including:

• Stronger hair
• Softer texture
• Smoother feel
• Improved shine
• Easier combing
• Reduced tangling
• Healthier appearance
• Less breakage during brushing

Up to 90% of users perceived their hair to be in noticeably better condition after using Keravis™ formulations.

How Keravis™ Works

Keravis™ utilizes an advanced multi-action peptide-silane technology that strengthens hair through two complementary mechanisms.

1. Internal Hair Strengthening

Low molecular weight peptide components penetrate deep into the hair cortex where they:

• Increase moisture absorption
• Improve elasticity
• Improve flexibility
• Reduce brittleness
• Reinforce damaged protein structures
• Form hydrogen bonds
• Form covalent bonds
• Increase resistance to mechanical stress

2. External Hair Protection

Higher molecular weight components remain on the hair surface where they:

• Form a lightweight protective film
• Lubricate the hair cuticle
• Reinforce the outer hair layer
• Reduce friction during grooming
• Protect against combing damage
• Reduce cuticle abrasion
• Minimize future hair breakage

This dual-action technology enables Keravis™ to repair existing damage while helping protect hair against future mechanical, chemical, and environmental stress.
