Avjou Researche® is the result of over two years of development alongside a leading cosmetic chemist and its founder, celebrity hairstylist Golnaz Avjou, who brings more than eighteen years of professional experience.
The commitment was to create a clean, elevated collection powered by patented actives that support thicker, fuller, stronger hair while helping maintain a youthful-looking scalp.
Below are the three patented ingredients used in the Hair Serum, each backed by cosmetic science.
Supports the hair’s natural pigment pathway to help delay visible grays with consistent use.
A larch wood and green tea complex that helps support density and fullness.
A patented peptide blend that reinforces fragile strands and supports a healthier-looking scalp.
“The effect of losing your hair is already emotionally painful, but greying at the same time compounds the issue and feels even more devastating. I knew I needed to make a difference, so I set out to create a brand that would tackle both challenges at once.
— Golnaz Avjou, Founder
