SILAB – AGREYNIST®, foil the natural processes of hair greying

HPC Today

AGREYNIST® 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.

 

AN UNPRECEDENTED ANTI-GREYING APPROACH

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. Indeed, a visual scoring by experts on photos highlighted that after 4 months of daily application, AGREYNIST® formulated at 2.

 

TWO PLANTS WITH COMPLEMENTARY EFFICACIES

In order to address effectively the issue of hair greying, SILAB implemented a screening of natural raw materials targeting the indispensable anti-free radical and pro-pigmenting effects. This work led to the identification of two raw materials: black oat seeds (anti-oxidant and detoxifying) and spiny restharrow roots (pro-pigmenting). The use of green solvents combined with enzymatic bioengineering enabled the optimized extraction of molecules of interest. SILAB thus concentrated and stabilized in AGREYNIST® the complementary efficacies of these two raw materials obtained from a controlled supply chain. With its protective, detoxifying and repigmenting action, AGREYNIST® (INCI name: Butylene Glycol & Water & Ononis spinosa Root Extract & Avena strigosa Seed Extract) offers a natural solution for grey hair care. Composed of biopeptides and polyphenols, this patented active is available in aqueous solution (recommended amount: 0.5 to 2.
