KEI HAIR STUDIO

About KEI HAIR STUDIO

KEI Hair Studio is a Japanese-inspired hair salon located in Tanjong Pagar, Singapore, founded by Wallace Sum. The name is drawn from the Japanese word 'Kei' (敬), meaning respect, reflecting the salon's philosophy of treating every client, every strand and every style with care.

The salon blends Japanese aesthetics with contemporary hairdressing, offering a full range of services including precision haircuts, hair colouring, bleach and balayage work, perms, rebonding, and a variety of specialised hair and scalp treatments. The team is led by Wallace Sum as Founder/Director, alongside Lead Stylist Roy Tai and Senior Stylists Joshua Low and Penny Goh.

KEI Hair Studio positions itself around continuous learning and tailored care, offering treatments designed to rejuvenate, repair and enhance each client's natural hair, from nourishing hydrating treatments through to a 13-step organic scalp and hair detox spa.

KEI Hair Studio: Japanese-Inspired Hair Care in Tanjong Pagar

In the heart of Tanjong Pagar, Singapore, KEI Hair Studio brings a distinctly Japanese sensibility to hairdressing, built around a name that carries real meaning: 'Kei' (敬), the Japanese word for respect.

A Philosophy of Respect

That philosophy shapes how KEI Hair Studio operates — treating every client, every strand and every style with care. Founded by Wallace Sum, the salon set out with a simple idea: to bring the grace and precision of Japanese hairdressing into Singapore's beauty scene, blending Japanese aesthetics with contemporary technique.

The Team Behind the Chair

Wallace Sum leads the studio as Founder and Director, working alongside Lead Stylist Roy Tai and Senior Stylists Joshua Low and Penny Goh. The team's stated focus spans haircuts, hair colour, treatments and styling, with an emphasis on staying current with the latest trends and techniques so each look is tailored to the individual's personality, lifestyle and hair goals.

A Menu Built Around Precision

KEI Hair Studio's à la carte menu is organised by service level and hair length rather than a one-size-fits-all price. Haircuts are tiered by stylist — Director, Lead or Senior — with prices differing for male and female clients, and every cut includes a wash and blow. For colour work, the salon offers single tone colour, highlights and 3D colour, balayage and air touch, and dedicated 'care bleach' and 'man bleach' options, with pricing scaled to hair length and additional charges for extra-long hair or bond treatments.

Beyond colour, the studio runs a full treatment menu, including the Chromalock Therapy and Atelier Rebuild Essence (both including a homecare kit), The Signature Atelier Duo, and targeted options like Silk Smoothing, Intensive Hydrating Treatment and a Strengthening Gloss for anti-frizz care. Perm and rebonding services round out the technical menu, from cold and digital perms through to point perm and rebonding by length.

Scalp Care and Spa Treatments

A standout part of the menu is KEI's organic scalp treatment range, anchored by a 13-Step Scalp & Hair Detox Spa available for both women and men (the male version excludes the hair treatment component). There's also a dedicated Anti-Sensitive Scalp Treatment and an Aroma Wash, which is offered as an add-on to other services rather than standalone.
