Your question may have a “yes” or “no” answer, Greta. Hair is complicated and mysterious and there are many, many variables happening from above the skin’s surface and below the skin’s surface that makes these questions hard to answer.
Let’s ask some more questions.
Does the hair follicle grow sturdier and stronger with repeated waxing, sugaring or plucking? Yanking out hair causes blood to rush to the injured area, right? Hair needs a good blood supply to grow, right? Blood carries male hormones, right? Might it be plausible to assume that under these conditions, is it possible that hair can become stronger?
Questions 2, 3, 4, are not considered controversial. This along with many decades of observations, is why it seems reasonable to me to advise my clients not to wax those facial hairs.
If a well-structured, long term clinical study (with more than 9 subjects) pops up with information that disputes a correlation between waxing causing more resilient hair growth,I would gladly fall in line and switch my views on this subject. Until then, I will continue to believe the sources in my electrology textbooks, along with my clients statements and my own observations.
