I always advise to do a college-type course or any course that would not be classed as a short course. I beieve you need to time to gain the experience as you may make it very uncomfortable for someone without the necessary experience. Hthx
As has been advised, i would go to your local college who provide vocational courses and look at the waxing courses, which are normally around 14 weeks long. This will equip you with the knowledge and skills to carry out a good treatment. i would also recommend investing in a waxpot so that you can ractice and perfect your skills at home.
