While many protein hydrolysates produce their effects on the hair surface or in the cuticle, BASF’s new low molecular weight protein Gluadin® Kera-P LM penetrates through the cuticle deep into the cortex. This is where it helps rebuild the hair with missing protein building blocks. On the hair surface, Gluadin® Kera-P LM provides protection for the cuticle. Where normally free radicals cause protein degradation ultimately leading to weak hair, Gluadin® Kera-P LM reduces hair damage thanks to its double protective effect: 1. It can diminish the copper bond with hair and reduce damage caused by oxidative stress: 2. It is able to intercept free radicals preventing premature hair aging. Gluadin® Kera-P LM is based on plant-derived protein building blocks that are free from wheat. With an amino acid spectrum very similar to that of keratins of animal origin, it offers a vegan and gluten-free alternative to conventional keratins.
