Gielly Green

What Gielly Green does

Gielly Green is a London-based luxury hair and beauty operator founded in 2008 by Shai Greenberg, running two salon locations — a flagship townhouse at 42-44 George Street in Marylebone and a second salon inside the Four Seasons Hotel London at Tower Bridge — staffed by 30+ stylists, colourists and beauty experts led by Artistic Directors Fred Gielly and Beryl-Renee Harrison. Services span precision cuts (from £90), colour (up to £500+), extensions, bridal styling, men's grooming, and a new The One Head Spa ultrasonic scalp ritual (£200–£350), with pricing tiered by stylist seniority and a 50% deposit on bookings.

The company has extended into consumer products via The One Hair System, a seven-SKU proprietary haircare line (Shampoo, Conditioner, Mask plus Scalp, Strength, Smoothness, and Shine boosters) built on the trademarked Sacred Trio™ ingredient complex of Moringa Oil, Saffron, and fermented Rice Water, manufactured in Italy by Beauty & Business S.p.A. (Alfaparf Milano Group) and validated by independent ISO-certified laboratory testing. Products retail £40–£58 individually, the Full Bundle is priced at £270.30, and a 20%-discount monthly subscription option exists; distribution is direct-to-consumer via a Shopify storefront on giellygreen.co.uk with worldwide shipping through Royal Mail, DHL and UPS.

The business model is a hybrid of professional services revenue (salon appointments at premium London real estate, celebrity and high-net-worth clientele) and DTC product revenue (subscription and one-off online sales), supported by the We Are One loyalty program and The One Circle affiliate scheme. Customer segments centre on luxury-conscious consumers and clients seeking hair or scalp transformation, with brand visibility across Harper's Bazaar, Tatler, Evening Standard, The Sunday Times and Condé Nast Traveller, and award recognition from the Good Housekeeping Institute (2026). The company operates as two UK private limited companies — Gielly Green Ltd (salons) and The One Hair System Ltd (products) — and is founder-led with no external funding disclosed.
