I don't think there are any ways to wax that are 100% risk free, but you can certainly wax at home without harming yourself. It's actually not too difficult once you get the hang of it.
I find that hard wax is easier to control than strip wax since you don't have to worry about the papers or cloth to get the wax off.
You can buy a wax pot online or at Sally's beauty supply or another beauty supply store. The pots can be anywhere from $20-100+ but they last for years.
If you have any other waxing questions, I'd be happy to answer them. I work at a spa and was taught to wax by an esthetician that all she does is waxing.
