TLDR Recombinant keratin K31 makes damaged hair thicker, stronger, and straighter.
The study investigated the effects of recombinant keratin K31 on human hair health and reshaping, finding significant improvements in hair strength, elasticity, and appearance. Recombinant keratin K31, expressed in E. coli and purified, increased hair diameter by up to 49%, doubled mechanical strength, and straightened curly hair after a single treatment. The protein's similarity to native keratin K31 allowed it to integrate into the hair structure, filling gaps and enhancing elasticity and strength, making it a promising ingredient for hair care products aimed at repairing and improving hair health.
