Texas Barber Exam Practice Test

Temporary color makes a physical change. This is because temporary color is a type of hair dye that coats the outside of the hair shaft, rather than penetrating the cuticle to make a permanent change. This means that the color can be easily washed out or fades with time. Choices A, B, and D are incorrect because they all refer to a more permanent change that occurs at a deeper level, such as altering the chemical composition of the hair or affecting its organic structure.
