Before you have the waxing done, exfoliate the skin. This will remove any dead skin allowing for easier hair removal. Give the area a day or two rest, especially if it's sensitive, and then resume exfoliating two to three times a week. By doing so, you are removing dead skin cells that can block the follicle. The exfoliating process encourages the hair to grow in pointing upwards so it doesn't curl back into the skin.
