Ive not done waxing for many years and when I did do it I only ever used the original pot and spatula method. Now im wanting to start offering waxing as a mobile treatment Im wondering what do use and am very interested in the roller wax system but never used it and not really quite sure how to use it either lol! What would be recommended for a mobile therapist thats only using it now and again? A single roller heater system? Im sooo confused please help lol!!
