Shaving, tweezing, Nair etc. will not make more hair grow. That's just an old wives tale. If you are getting more hairs, then you are just getting more hairs, it isn't from tweezing. If anything, tweezing over time can actually kill the hair follicles. Nair can be very irritating to your skin so test it as the directions tell you first or you may end up with a raw face.
