Prerequisite(s): COSM 111, 112, 113, 121, 123
This course is a study of methods of chemically relaxing the structure of hair including product, chemistry, and safety. This course emphasizes the removal of curl from overly curly hair by the use of chemical agents. Upon completion of this lesson, students should be able to describe the structure and composition of hair, explain the impact of acids, alkalis, and pH on the hair and scalp, determine the relevance of porosity, density, texture and elasticity of the hair for chemical services, describe structural changes that take place in hair as a result of chemical relaxers, explain the factors critical to hair and scalp analysis, and apply a chemical relaxer correctly.
