Dedication Many people might be helped or comforted by timely advice and treatment from their family physician before being obliged to consult the hair-specialist, particularly those who lack the time, the opportunity or the money to take special treatment. This work has been undertaken in the hope that it may arouse the general practitioner to take more interest in and have more knowledge of a subject which is of first importance to more persons than any but the specialist realizes. In this hope this work is dedicated to my colleagues in the profession. Richard W. Muller, M.D., A.M.A., Ac.Med.
