Hair ageing is a concern world-wide, representing a major potential for the beauty industry: 59% of consumers on average are worried about hair ageing (mainly Japanese and Chinese who are above average) and over 60% of them are currently bothered by hair colour loss¹.
If genes can play a large role in hair whitening, it is now well-known that free radicals are directly inducing the premature greying of hair for both men and women. Most of the existing hair pigmentation solutions are based on hair colourants, artificially repigmenting the hair shaft but not addressing the origins of hair whitening.
Givaudan’s skin experts have designed Darkenyl to counteract the hair whitening biological process, by combining two synergistic molecules, the taxifolin glucoside, a unique stabilised plant polyphenol and N-acetyl-tyrosine, a soluble precursor of melanin synthesis.
Darkenyl boosts hair stem cells proliferation (+30%) and migration to help the hair matrix with new melanocytes. Its antioxidant properties enable the reduction of free radical damage in hair follicles (-53%) and also helps to protect existing melanocytes (+189%). Once the hair matrix has been repopulated with new melanocytes and both new and existing melanocytes are protected from ROS, Darkenyl delivers its melanin synthesis precursor to reactivate melanogenesis (+364%).
A clinical study versus placebo using white hair proportion scoring on hairlines and white hair density quantifying on a shaved scalp area have demonstrated the significant consumers’ benefits of Darkenyl: in four months, volunteers had more than three times less white hair/cm², with up to -56% reduction of white hair. The unique action of Darkenyl is patent-pending, gender independent and can be used on any hair type or colour. It shows progressive and long-lasting results.
Amandine Scandolera, Head of Biological Evaluation, said: “The knowledge of the different mechanisms involved in the development of canitie are increasingly consolidated to demonstrate the key role of the scalp oxidation, which was, up to now, less considered in the scientific strategies implemention.
With the development of Darkenyl, we offer an effective solution through the reactivation of the main altered mechanisms at the origin of canitie such as reduction of oxidation, reactivation of melanocytes stem cells and increasing of melanogenesis. Having white hair is definitely not an irreversible phenomenon anymore!”
To inspire the beauty industry while showcasing the high potential of this new ageless hair technology, our experts of formulation crafted S3D Colourback, a repigmenting and conditioning serum to beautify and rejuvenate the hair.
S3D Colourblack features Darkenyl and ResistHyal, which is the ultimate hair beauty enhancer (optimised hyaluronic acid), this product quickly penetrates into the scalp and spreads on the hair while activating the repigmentation process and protecting the hair follicles. With its innovative comb, S3D Colourback enables a precise and effective application, directly on the roots.
