Introduction

Hair, which has an essential physiological role in animals, is mainly of psychological importance in man. A good head of hair provides some degree of warmth for the human head and also protection from ultraviolet radiation, but its significance is otherwise in the eye of the beholder. In the form of wool, hair is of economic importance and considerable research has been carried out into the cycles of growth and the structure of wool keratin in sheep.

Too much hair, particularly on the face of women, is an embarrassment and cosmetic problem and loss of hair from the scalp is equally troublesome. Changes in hair growth are not only of cosmetic significance but can also be associated with underlying diseases. Diseases occurring in the skin of the scalp can damage hair follicles leading to loss of hair. This chapter covers: (a) the normal pattern of hair growth; (b) causes of hair loss; (c) skin diseases involving the scalp; (d) causes of excess hair growth; (e) abnormalities of the hair itself; and (f) treatment.
