Unlike shaving or trimming, the hair growth pattern is not going to be thick for sure. But, if you wax every 4 to 6 weeks, you will surely notice thinner hair strands. However, post 8 or 9 weeks, the thickness of the hair strands will retain and you might notice thicker strands. Even though many people think otherwise, waxing does not really have a permanent impact on the density of the hair.
