Entering the Heavenly Touch Hair Studio is like taking a step back in time. Red plastic swivel chairs sit on a checkerboard of retro black-and-white linoleum. But amid the faded posters advertising hair straighteners and dye there is a decidedly modern South African touch. A small, black and orange sign warns visitors that here at Heavenly Touch, certain behaviour just won't be allowed. "Right of admission reserved," it reads. "No racists allowed." Over the past year, the "no-racists" signs have been showing up in business windows around this notoriously conservative town.
