Selfish Spitalfields is a nail salon in Tower Hamlets specialising in BIAB (Builder in a Bottle) manicures. Their artists are trained in the Ukrainian dry cuticle technique, where skin is cleaned back rather than cut, allowing the builder gel to be applied flush to the nail base to prevent lifting. BIAB is a flexible builder gel applied over your natural nail, not an extension, adding a protective layer that keeps nails strong for four to five weeks. New sets start from £56 for short nail plates, infills from £60. The salon offers over 600 gel colour shades and nail art options.
