Interior Space and Exhibition Design Salon Trinity Hair Salon by Alvin Lee Salon Trinity is a hair salon interior in Hong Kong. The design applies a spa concept to hair dressing, creating a calm escape from the urban setting. White sheer curtains soften the space and the mood. Timber look tiles add warmth. Full height triptych mirrors with concealed lighting make the space feel larger. An oversized round mirror stands outside the washing area as a visual and physical barrier and as the emblem of the brand. The triangular floor area of 80 square meters is planned so that each seat has enough working space and clear circulation.
