This book will help you to understand the philosophy, the history, and the power of colour and, perhaps more importantly, it will also show you how, with step-by-step photo sequences, to take the uncertainty and complexity out of colouring hair. David Adams is one of the UKÂ's leading hair colourists and is technical director at the AVEDA Salon in Harvey Nichols, London. His reputation for technical brilliance and innovation in new techniques mean he commands the utmost respect from the industry and trust from his clients. As such, he is the ideal author of a book on hair colouring for his fellow professionals, students training as hairdressers, and those involved in teaching and training.
