This scientific discovery is proven to strengthen the hair by penetrating the cuticle to build hair from the point of damage while strengthening the outside of the hair follicle by forming a film that reinforces, lubricates, and protects hair. Studies confirm that Keravis tripled the strength of damaged hair, versus a traditional conditioner. In addition, Keravis remains effective at high humidity. When compared to panthenol, a widely-used conditioning agent, Keravis was 50 percent more effective in increasing hair’s strength.
