It all really depends on the strength of the hair, the tecnique you use and the quality of the wax used by the particular brand also plays a part. If you have the average level of hair you can usually get some good results. However, if you have coarse, tough hair, which some people do have the results may not be as good.
The best trick is really to try it out on an area for example your legs, this is generally a better idea than lets say your bikini line because firstly if you don’t do it properly it’ll be a lot less painful. Secondly, if it won’t work on your leg hair there’s a good chance it won’t work on an area like your bikini line or under arms where the hair is much tougher.
However, the most effective waxing method is using salon wax (doesn’t necessarily have to be done at a salon if you know how to do it and so on, but that does take time to acquire that skill and sometimes a lot of pain )
