Now available for retail in the US, these fabulous London born Rock & Ruddle hairbrushes keep your hair shiny and healthy, thanks to natural boar bristles that release and drag oil from your scalp and distribute it throughout your hair. These bristles have a natural stiffness that brush through hair without pulling, as well as microscopic scales that stimulate and exfoliate your scalp, encouraging hair growth. Rock & Ruddle mixed bristle hairbrushes also have a flexible nylon pin in each tuft which painlessly detangles knots. The rubber cushion ensures gentle brushing and is removable for thorough cleaning. The hairbrushes are available in small, large, and luxury sizes, with several options for bristles: Pure Bristle, Mixed Bristle, Very Soft Baby Bristle, and Synthetic Bristle. Rock & Ruddle hairbrushes also come in dozens of fabulous designs.
