Two more reasons for going to a professional the first time:

  1. The first time hurts the worst. Your hairs are well rooted; after the first time they will be weaker and easier to pull out.

  2. You can watch how they do it and have a good example to follow. That is, of course, if they know what they're doing. Just because a person does something for a living doesn't mean they're good at it. Get a recommendation.

The big thing I learned was baby powder. Put it on before the wax. It will save you from ripping your skin off. People's skins are different, and many people don't seem to need it. But if I don't use it, I end up tearing off some skin along with the hair.

Also, waxing won't work at all if your hairs are too short.
