One of those advantages is that the removal is not permanent. While that may seem like a contradiction, there are actually times when it's a good thing that hair will grow back. Consider the plucking of the eyebrows. While your eyebrows may be bushy and it may very well be a constant battle to stay on top of the situation, you at least have the opportunity to reshape every few months. If you use one of the more permanent methods of hair removal, a misshapen eyebrow may mock you every time you look in the mirror for months. You can also more easily experiment with shaping, deciding what looks best for your face.
Another advantage is that there are no chemicals involved with tweezing and little fear of a chemical reaction with waxing. The person who waxes or tweezes the eyebrows will have a swollen area that is red for a few hours, but there's little or no danger that you'll have a reaction to some chemical in the solution you're using that will leave you with hives, sores or some other reaction.
Finally, a major advantage for some people is the cost of waxing and tweezing. A pair of quality tweezers cost only a few dollars and will last for years. Waxing is slightly more expensive but is typically less expensive than many methods of hair removal, especially when talking about the more permanent hair removal methods.
In the end, it's up to your discretion whether to use one of these very traditional methods of hair removal or to try one of the newer methods on the market. Consider the alternatives before you make your decision.
