Hair Strengthening Protein
Healthy hair is resistant to breakage because it demonstrates flexibility within its cortex as well as maintaining cuticle integrity. Through daily grooming and styling, hair is subjected to tensile forces, bending stresses and cuticle abrasion that ultimately cause a weakening of the hair fiber itself in addition to damaging the cuticle layer.
Increasing the strength of the hair is a two-fold strategy that must address both its inner flexibility along with the integrity of its surface layer. With an intermediate-range molecular weight of 1800, Keravis™ (INCI: Hydrolyzed Vegetable Protein PG-Propyl Silanetriol) addresses both of these issues by simultaneously penetrating the hair shaft to optimize moisture content and plasticity of the hair, while also forming a cross-linking film that coats the hair to lubricate, protect and reinforce the cuticle. Hair treated with the Keravis strengthening active shows a proven increase in hair strength - triple the strength of damaged hair compared to a control conditioner. Treated hair can demonstrate the increased resilience, flexibility and reduced breakage seen in healthy hair.
RevivHair Stimulating Conditioner utilizes this patented protein to address the three fundamental parameters of hair strength: tensile properties, bending modulus and cuticle abrasion.
