Hair Follicle And Hair Growth Summary

This short novel accurately portrayals a complete understanding of the hair follicle and hair growth. Written by David A. Whiting, his introduction begins by covering hair embryology and concludes by describing methods of scalp biopsies. The preface of the book mentions how it will provide a “three-dimensional view of the human hair follicle . . . visualizing [it] at different levels and in different phases of the hair cycle demonstrates the correlation between vertical and horizontal sections” (Whiting 6). Sequentially, this is supposed to recognize hair changes and abnormalities. The next section written on human hair follicle anatomy is the center and main idea of the book. Whiting starts this section with the terminal anagen hair, depicting
it primarily by photomicrographs both vertical and horizontal sections at disparate levels, from the hair bulb through the lower follicle and isthmus and eventually to the final part, the infundibulum. Also, examines the characteristics of terminal catagen and telogen hairs and normal follicular tracts. Lastly, Whiting writes on follicular counts executed on vertical and transverse sections.
