Although it may feel counter-intuitive, clients will be encouraged to shave the body part that is going to be treated with the laser hair removal a day or two before their appointment. The laser will be able to easily locate hairs that are very short or just growing form the follicle better than they would with longer hairs, and will not need to use up as much energy burning away the length of the hairs, making the session go by a bit faster in general. As well, there are fewer risks of the laser causing minor damage to the skin surrounding the hairs if the hairs are shorter as the laser will be able to target only the hairs and the follicles more easily.
