Waxing your upper lip will have no effect on how it grow back worst than before. Hair will grow back after two weeks after you've waxed them.

Time for you to start shaving. Some girls develop a moustache, just like boys do. Most guys are OK about girls with, for example, a slight moustache. If you do decide you have to do something, then there isn't a simple answer and there's a lot of misleading "information" around. Facial (and also body) hair on women comes about in the same way as on men because of 1) your body being sensitized, before you were even born, to testosterone -- doesn't happen to all girls, but does to many 2) your body producing high levels of testosterone The growth rate and coarseness of the hair depends on just how much testosterone is circulating in your bloodstream. Steer clear of bleaching -- when someone sees you against the light you'll look as if you have a glowing moustache. Believe me, it shows up far, far worse. As far as removing it is concerned it's worth remembering that * Waxing, plucking, threading, epilating all pull the hair out by the roots and where the growth is hormonally-driven can actually stimulate a dormant follicle into producing more hair quicker. They also distort the root if done repeatedly, leading to hair growing at strange angles. And you've got to let the hair grow to quite a length before you can repeat the exercise. It can also damage the skin and discolor it. Long-term use of waxing also causes bad wrinkles. * Chemical depilatories strong enough to remove the hair are very likely to burn the skin, cause swelling and cause long-term discoloration of the skin. * Laser is also liable to cause burning and discoloration and in any case only works effectively on a dark hair/light skin combinantion. * Electrolysis is very liable to cause scarring and discoloration of the skin. Which, like it or not, leaves shaving which does not damage the skin and does not cause the hair to grow more or coarser or faster. Best done with a men's-style electric razor, the best of which, for girls and women, are probably those from the men's range of Philips/Norelco razors (Philishave outside the US). Most girls and women who try a men's Philips/Norelco wonder why nobody ever told them about it before.

DO NOT SHAVE. These people don't know what they're talking about. Waxing the best way to go. It gets rid of hair for at least a month. I started waxing my lip at 19 and then stopped at 25 and don't need to anymore because the hair stopped growing in. If you shave, you'll have a 5:00 shadow that will be super hard to get rid of.
