GK Hair began 11 years ago with the vision and the values of his founder, Brazilian born Van Tibolli. From the start GK Hair has been the leader in 'the science of hair'. The concept is very simple; develop and deliver new and creative ideas to a global marketplace. GK Hair is the first and only company to harness the beauty benefits of Juvexin, a keratin anti-aging protein blend obtained from the sheep wool through an eco-friendly process.
