What is the main reason for applying a hot towel to a client's face prior to a shave?

Applying a hot towel to a client's face prior to a shave serves the primary purpose of opening up the pores and softening the hair. The heat from the towel increases blood circulation, which can enhance the overall experience and prepare the skin for the shaving process. Softening the hair makes it more pliable, resulting in a smoother and closer shave. This technique not only helps with the ease of shaving but also minimizes the risk of skin irritation and razor burn, as the softer hair allows for a gentler and more effective shave.

While relaxation is a benefit of the hot towel, its main physiological function is to prepare the skin and hair for shaving, ultimately contributing to a better outcome for the shave.
