Abstract

Hair trichogram is a semi-invasive, qualitative, and quantitative method used for decades by dermatologists. The microscopic examination of plucked hairs provides reliable information about hair root, shaft, and viability which are good indicators for diagnosis, prognosis, and treatment of many types of hair disorders. Thanks to its reproducibility, the trichogram is also used in routine patient follow-up and in clinical trials as a primary endpoint.

This technique is simple and inexpensive but needs a short training in the plucking procedure as well as in the reading. This chapter will provide the material, method, morphological features, and clinical applications of the method.
