Review Of How Long Does Waxed Hair Take To Grow Back References. Web on average, a wax will last you three to four weeks. Web once you've received a successful wax, getting it back to ¼ of an inch hair growth for waxing should take a minimum of at least two weeks on finer hair areas like the face, and four to six weeks on thicker hair, as found in the pubic region.

So what’s the science behind this (rather bold) statement? In fact, many people actually see regrowth much sooner. For example, coarse hair tends to take longer to grow back than finer hairs, so those areas may be smoother for longer.
