The  aim  of  the  work  is  to  improve  the  work  of  hair  styling  devices,  which  is  aimed  at increasing  the  efficiency  of  hair  styling  under  the  action  of  sufficiently  high  temperatures  with  the  least damage to it. To achieve this goal, the following tasks were solved: the relationship between the physical properties  of  hair  and  temperature  regimes  of  curling  was  analyzed;  experimentally  investigated  the distribution of curling temperature during heating and cooling; the distribution of the temperature of the curling iron when heated with dry hair and with moist hair was experimentally studied. Methodology. The methods of mathematical modeling, methods of mathematical physics, methods of experimental researches with processing of results of experiment by means of a modern software product and computer equipment are used in the work. Findings. Analytical and experimental studies have shown the need for a uniform temperature field on the surface of the work surface to achieve the desired result. The necessity of temperature regulation in devices for work with hair is proven. Originality.  The  possibility  of  using  the  installation  for  experimental  evaluation  of  temperature control  in  devices  for  working  with  hair  is  substantiated,  which  will  significantly  increase  the  time  of continuous operation of the device and reduce electricity consumption. Practical value.  A stand for research and analysis of different temperature regimes of electrical appliances has been developed. The thermostat circuit for temperature control in devices for work with hair is applied. It has been proven that you need to choose the temperature in relation to the condition and type of hair, so as not to cause great harm. Due to its small size, economic and technical indicators, this stand is easy to use when studying the temperature conditions in devices for working with hair in the work space, which contributes to more modern and demonstrative training. It is proposed to use the two-position law of temperature regulation for the surfaces of the working bodies.
