Abstract

This article describes the diagnostic method of phototrichogram, which is used in the diagnosis of trichologists. Using a phototrichogram, the following objective results can be obtained: the number of hairs in the growth and loss stages (anagen and telogen), after which these indicators are compared with the physiological norm of hair loss in this patient; the diameter of the hair in different areas of the scalp; calculating the rate of hair growth for this patient; to track the results of treatment over time (an increase in the number of hairs per square centimeter, the density of hair growth per square centimeter, the amount of hair in the anagen and telogen stages). The nurse plays an important role in this method. The features of the procedure, the necessary equipment and its processing are described.
