No. It can be surprisingly easy to wax yourself, once you've become familiar with the technique.
Some areas are easier to to than others, for example: waxing your legs is a simple straight-away and a great place to start honing your waxing skills.
When you feel comfortable handling the wax, then move to an area like your underarm or bikini, which are areas that tend to have more bends.
Much like riding a bike, as soon as you've got it - you've got it!
Don't be afraid, if your hands can reach it, then they can wax it too.
