In the article the effect of exogenous factors on the state and properties of hair on the human head using various techniques of microscopy as well as other morphometric methods are studied; on the basis of experimental samples the physical properties of healthy hair and the hair damaged by external factors by using microscopy techniques were compared; the article presents the values of pH and the content of surfactants (sulfates) in different brands of shampoos and soaps, and their impact on the condition of the hair was determined; on the basis of microscopy techniques the condition of the cuticle after using different detergents for hair care was characterized; a relationship between the color of the hair and the influence of external factors on the structure and condition of the hair was analyzed; the signs of the impact of external factors (chemical, thermal, mechanical) on the state and structure of the hair, using an optical (light) and an usb-microscopes were identified.
