The hair grows in the three different cycles. In order for the laser to be effective the follicle needs to be in the first anagen, or active stage of growing. When you wax, you remove the follicle or the root of the hair and leave no target for the laser to attract. If you wax, it is better to wait 4-6 weeks for the face areas and 8-10 weeks for the body areas for the hair to return in the right stage again. You can simply shave before and in between the treatments or use any depilatory creams that remove the hair on the surface only.
