THE FOUNDERS — Guided by purpose, passion, and respect for each individual. We create with meaning, celebrating the ritual and artistry of haircare, and the results speak for themselves.

Shai & Karin Greenberg, the founders

"Our vision is to challenge the conversation of the haircare industry by creating simplicity in a world of confusion- delivering not just high-performance results, but a sensorial ritual that speaks to identity, confidence and self-expression. We’ve distilled two decades of salon insight into a system that’s intuitive, luxurious, and transformative."

Shai Greenberg

With nearly four decades in hairdressing and 18 years leading the Gielly Green team, Shai’s craft is defined by experience, artistry, and integrity. As the creative force behind the chair, he has shaped Gielly Green into one of London’s most respected salons with a philosophy built on care, craftsmanship, and uncompromising standards. His deep understanding of every texture, type, and challenge has shaped a philosophy grounded in real results, professional expertise, and effortless simplicity.
