That is why Provital is launching a new active ingredient for hair care that can act at the molecular level, protecting the hair fiber from oxidative damage caused by two commonly used stressors, heat and bleaching, while also preventing future damage.
Thanks to the combination of science and technology, and collaboration with companies and leading technological infrastructures using cutting-edge techniques, this natural active ingredient is the perfect solution for the most demanding consumers who do not want to give up potentially damaging hair treatments but still desire strong, healthy, and protected hair.
Provital shares: "With Keradeep, we explore the world of the invisible and evaluate its effects on hair using various techniques. We utilise a patented fluorescent probe to tag carbonyl groups and measure the levels of carbonylated proteins in hair after bleaching or heat application. Additionally, to demonstrate Keradeep's ability to prevent hair carbonylation caused by bleaching, we employ ALBA synchrotron technology. We also showcase Keradeep's protective effect in maintaining the positional structure of keratin using Xpolar® technology."
These studies have shown that Keradeep works from within to protect cuticle proteins from oxidative stress by 68% and cortex proteins by 71%, preventing the appearance of carbonyl groups and the formation of oxidised cysteine species. Additionally, it exhibits protective antioxidant capacity and preserves keratin structure by 94% against stressors such as heat or bleaching.
Keradeep is derived from pine bark extract (Pinus Pinaster), a compound rich in polyphenols with antioxidant activity. It is 100% of natural origin (ISO16128), Halal certified, and meets COSMOS and vegan standards. It combines nature and science to enhance hair strength and achieve healthy, protected hair from within.
