Gielly Green, one of London’s most celebrated luxury hair salons, announces its retail partnership with John Bell & Croyden.
Marking an important milestone for the brand, the partnership brings The One System - Gielly Green's signature high-performance haircare collection, developed from decades of salon expertise - to one of the UK’s most respected luxury pharmacies and beauty destinations.
Created by founders Shai and Karin Greenberg in Gielly Green’s award-winning salons, The One System was developed to solve one of beauty’s biggest frustrations: the overwhelming complexity of haircare. The result is a core trio of essentials - One Shampoo, One Conditioner and One Mask - paired with four targeted leave-in Boosters for scalp health, strength, smoothness and shine, designed to meet 80% of hair needs with elegance, precision and ease.
Karin and Shai Greenberg, Co-Founders of Gielly Green, said, "John Bell & Croyden has spent over two centuries bridging healthcare and holistic lifestyle, treating inner vitality and outer appearance as one conversation. The ONE was built on that same belief hair isn't separate from wellbeing; it's part of it. To launch with a team who thinks in those terms, not just retail terms, is exactly the home we wanted for it."
The One System is powered by a sacred triad: Moringa, Saffron and Rice Water, drawn from ancient traditions across Africa, Persia, and Asia. The trio works together to protect, transform, and heal, delivering powerful results for scalp health, hair strength, and overall well-being through modern trichology.
The partnership marks the first time The One System will be available in a luxury pharmacy, making the brand accessible to a wider audience through a retail partner renowned for its heritage, trusted expertise and curated beauty and wellbeing products.
Alexander Johnston, General Manager at John Bell & Croyden, said, "We are delighted to welcome Gielly Green to John Bell & Croyden, bringing together two iconic brands that share a commitment to exceptional service, expertise, and luxury. This partnership enhances our offering and creates a unique destination where beauty, wellbeing, and personalised care come together.”
The One System is available online now at John Bell & Croyden, and in-store with a dedicated counter within the retail space at 50-54 Wigmore St, London W1U 2A.
