Applying a layer of hot wax or sugar paste to the skin and later ripping it off along with the hair can provide a solution which lasts up to four weeks. It is relatively cheap but needs regular application. Depilatories are creams which can be applied to the skin area and removed after 20 minutes or so taking the hair with it. The treatment often does not last as long as waxing. Again this method is relatively cheap but needs repeating frequently.
Tweezers are very cheap but it is time consuming and there is a risk of ingrown hair.
The hair often grows back thicker and darker. Shaving of course is cheap and quick. However, there is the risk of cuts and nicks to the skin unless you use an electric shaver. This method causes some inconvenience due to the regularity with which it has to be done. From the foregoing it becomes evident that there is no ideal solution to the problem of unwanted body hair.
