<P> The hair follicle is a dynamic organ found in mammalian skin . It resides in the dermal layer of the skin and is made up of 20 different cell types , each with distinct functions . The hair follicle regulates hair growth via a complex interaction between hormones , neuropeptides and immune cells . This complex interaction induces the hair follicle to produce different types of hair as seen on different parts of the body . For example , terminal hairs grow on the scalp and lanugo hairs are seen covering the bodies of fetuses in utero and in some new born babies . The process of hair growth occurs in distinct sequential stages . The first stage is called anagen and is the active growth phase , catagen is the resting stage , telogen is the regression of the hair follicle phase , exogen is the active shedding of hair phase and lastly kenogen is the phase between the empty hair follicle and the growth of new hair . </P>
