There is no ideal working temperature for depilatory wax, as each type and brand behaves differently. Many wax manufacturers include application temperature recommendations on the label, but these only serve as a broad reference since you should also factor in the conditions in your location (AC, room heating, humidity). What you should aim for instead is to get the right consistency, which is that of honey or molasses. If the wax is too liquid, you have to turn the dial down a little on your wax heater, and if it is too viscous, slightly turn it up. You should also test the wax temperature on your wrist before applying it to the client's skin. Quick reminder: When using soft wax, you should set the temperature on the depilatory wax warmer lower than for hard wax.
