After having investigated hair regrowth and launched Hairgenyl, last year, the French supplier of natural cosmetic active ingredients focused on the fight against natural processes of hair greying through an innovative approach.
“Greying of hair is an unavoidable phenomenon, however, there is a strong consumer expectation to avoid it with natural solutions,” says Silab in a statement.
In order to effectively address the issue of hair greying, the company launched an in-depth screening of natural raw materials, targeting the anti-free radical and pro-pigmenting effects. This work led to the identification of two botanical 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.
Visible reduction of hair greying
The repigmenting effect of Agreynist  was demonstrated in vivo on a panel of Caucasian and Asian, male and female volunteers. Indeed, 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 stage of greying by 20% (P < 0.001) on Caucasian volunteers, corresponding to an average decrease of one stage of greying (result visible in 91% of volunteers).
A subjective evaluation confirmed these data, as after six months of use, 91% of the volunteers reported that they have fewer grey hairs and 88% of them considered that it is an anti-grey hair product.
“With its protective, detoxifying and repigmenting action, Agreynist offers a natural solution for grey hair care,” concludes Silab.
Composed of biopeptides and polyphenols, this patented active is available in aqueous solution (recommended amount: 0.5 to 2.5%) and compliant with international cosmetic regulations (Europe, United States, Japan, China, etc.).
