Pastel Hair/Summer Staple. Featuring our own colour-tech Carolyn Mila, who pulls off the purple/gray pastel perfectly well. Carolyn’s expertise focuses on ammonia-free colour, primarily of all hues of the rainbow. Ironic, because this quality of her’s works well with her similar personality. If you’re looking to take a leap with your colour, Carolyn’s your girl – in a setting free from harsh chemicals, of course.
