Solution based on PolyGraft-9, a highly reactive cysteine protein—developed by a former Senior Vice President of Chemistry for Redken that was discovered by his grandson
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 better condition than before we started,” said Marina Kenard, a stylist of over thirty years who personally worked with Dr. Hunter.
Super Tiger (QAI’s Salon Only version of Tiger Reconstruct) actually uses oxidation to enhance repair, meaning the hair is intentionally softened to enhance the Covalent Grafting. (This has never been done before, to intentionally oxidize and break the disulfide bonds in order to enhance the permanent repair) Covalent Grafting, as explained by QAI, is the process of chemically growing and permanently splicing a synthetic polypeptide (PolyGraft-9) into the alpha-helix (the innermost layer of the hair).
Working in combination with PolyGraft-9 and the Tiger Catalyst (a Covalent Bond Conversion Catalyst), Tiger Reconstruct, Tiger Masque, Tiger Moisture Mist, and Super Tiger become more reactive with oxidation in the hair. This means that the product is enhanced with more damaged hair. The PolyGraft-9 Complex used in the Tiger products also will only bond with negative charges inside the hair, which is how the product prevents over-proteinizing.
This result is not a mere cosmetic treatment. Rather, the process restores hair to its natural covalent state using a fundamental molecular repair solution.
QAI Hair has tested the product line extensively. Early adopting salon partners are sharing that Covalent Grafting Technology works with outstanding results in repairing damaged hair that was previously seen as too compromised to fix.
