Due to waxing being such a complete method of hair removal, regrowth can take a significant amount of time to materialize, provided the hair is removed correctly and completely
Reports typically advise that noticeable regrowth starts to occur between 4-6 weeks, with most people pursuing a waxing session around that time frame as well. However, there are a number of factors that can affect the rate of regrowth, and thus how often it is necessary to have the treatment done, or simply how quickly you may have noticeable regrowth.
Age
As we get older, many people find that their hair growth is lessened, and becomes finer and occasionally even fairer as part of the aging process. While this is not a guarantee, it is not uncommon for older individuals in their 50s or above to have a much longer window between waxes than someone younger. Alternatively, some people find that as they are their hair may actually become coarser, which would negatively affect the timeline between waxes.
Hormones
Going hand-in-hand with the aging process, hormones can also dramatically affect the rate of hair growth on your body. For young people going through puberty, there is almost always an increase in hair growth, and occasionally this is the same for women going through pregnancy. During both puberty and pregnancy hair may become coarser or darker than it was previously, leading to more noticeable regrowth and a shortened hair-free window between waxes.
Genetics
Your family heritage and genetics can also influence the rate of hair regrowth, as well as how long waxing results will last. Some people find that certain ethnicities experience more substantial hair regrowth than others, and this undoubtedly affects the rate of regrowth and the length of time that can be stretched between appointments.
Breakage
Coming down to the skill of your esthetician and the strength of your hair, if your hair breaks during the waxing process, regrowth will naturally appear much faster, as the root has not been completely removed. While some breakages are to be expected, especially if it is your first time waxing, you may find that after a few sessions your hair becomes easier to remove, and less occur. This will draw out the length of your results, and allow for a longer period between treatments.
While the majority of people find that waxes last from four to six weeks, the length that you can wait between sessions is influenced by a number of physical factors and waxing history, not to mention your individual tolerance for hair regrowth and stubble. Even consulting your esthetician is unlikely to yield more definitive results; the best way to get an understanding of the longevity of waxing results is to have a session done at your local salon, and from there to plan your future schedule accordingly.
