Do not tweeze, bleach or wax for at least three weeks before treatment. Shaving is completely safe. You will not grow more hair if you shave. The best way to come in for treatments is cleanly shaven or with a very slight stubble. We suggest shaving the night before or the day of your scheduled treatment, but not more than one day unshaven. If you come in for treatments with too much hair, we will have to shave you which takes time and could be irritating to the treatment area.
