Provital launches Kromboost™, an upcycling protein bioactive designed to preserve the functional life of the hair fiber by maintaining structural integrity, hydration and color under thermal and chemical stress. Derived from locally sourced barley malt rootlets, a craft beer brewing byproduct, through an enzyme hydrolysis, Kromboost™ delivers peptides and polyphenols, enhanced with serine, in one multifunctional, dual-action ingredient that works on the hair surface and within the fiber to reinforce keratin structure. Tested ex vivo across straight, wavy and coily hair types following repeated 230ºC flat-iron styling, 2% Kromboost™ cut breakage by up to 152%, boosted keratin thermal stability by up to 15%, increased moisture retention by up to 19%, and improved dyed color retention up to 199% in leave-on use or by 166% in a 3-minute rinse-off application. Halal, Cosmos approved, vegan and 100% natural origin, Kromboost™ provides formulators a sustainable, science-backed solution aligned with the hair longevity approach.
