Title: QAI Hair Launches World’s First Covalent Grafting Polypeptide to Repair Damaged Hair

United States, 4th Aug 2026 — QAI Hair today announced the launch of a line of hair care products featuring the world’s first Covalent Grafting Polypeptide. The products’ Covalent bond Conversion Catalyst represents the final evolution of molecular hair repair, which restores hair back to its permanent natural covalent state. The line is based on PolyGraft-9, a highly reactive cysteine protein developed in secrecy but never released by the late Dr. Lee Hunter, former Senior Vice President of Chemistry for Redken. Dr. Hunter’s grandson, Kollin King, discovered the formula and is bringing it to the market.“I was always fascinated by my grandfather's ability to create, and I was always seeking to understand. But of course, everything he did was very secret," Kollin explained. “It was to my surprise when I stumbled across a box of his research and found Super Tiger, looking for another formula, that I saw the science behind PolyGraft-9 and the Tiger Catalyst and it inspired me to carry on his legacy of Covalent Grafting into the next era.”PolyGraft-9 imitates protein synthesis by growing a synthetic polypeptide into the alpha-helix (innermost layer of the hair), permanently grafting the bonds back together. This is why it is the only product that can even repair hair that has been burned or overoxidized from chemical damage to the point where it is pulling apart and gummy because it permanently replaces missing mass with Covalent Grafting Technology. “Most stylists would just be forced to cut the hair off after it reaches that point, but not with PolyGraft-9. Now there is a way to splice it back together with Covalent Grafting even with the most damaged hair…and when used in buffer in bleach and perming solutions, the hair comes out unscathed and in many cases in bette...
