Written for the practising electrolysist and student, this book covers the three methods of electro-epilation and takes into account recent changes and advances in technology. These changes are wide-ranging and encompass topics such as the advent of AIDS, the development of pre-sterilized disposable needles, training, and health and safety at work. A knowledge of endocrinology, the structure and growth cycle of hair, the skin, hygiene, electricity and basic first aid is essential to understanding why hair growth occurs and how this problem, which causes distress to very many people, can be treated both safely and efficiently.
