The ingredients supplier Silab presents its latest natural active ingredient Agreynist®, designed to foil the natural processes of hair greying. It is an anti-free radical and pro-pigmenting active ingredient of plant origin, enabling greying hair to return to its natural color without the need of dyeing it.
Greying of hair is an unavoidable phenomenon, however, there is a strong consumer expectation to avoid it with natural solutions. Faced with this observation, Silab developed Agreynist®, a natural active ingredient capable of regulating the biological pathways leading to greying, in particular:
• It restores the oxidative balance of hair, a necessary factor of any anti-greying strategy, not only by reducing the formation of free radicals, but also by activating cell detoxification induced by autophagy
• It favors repigmentation of the hair fiber by stimulating the synthesis of melanin with its cytoprotective effect
• It re-establishes the structural quality of hair (result from an original modeling study*).
*Using Raman microspectroscopy, SILAB conducted a more detailed analysis of the course of greying and, in a novel way, has shown that there are changes in molecular markers related to biomechanical properties (conformation of proteins) and to the barrier function (organization of lipids) in grey hair.
A repigmenting effect
The repigmenting effect of Agreynist® was demonstrated on Caucasian and Asian, male and female volunteers.
A visual scoring by experts on photos highlighted that after four months of daily application, Agreynist® formulated at 2.5% in a lotion significantly decreases the …
