Myth or not: Shaving makes your hair grow back thicker?

Updated: Feb 18

Myth or not: If you remove facial hair, it will come back twice-fold and tougher? 

MYTH. This myth was dispelled about 90 years ago by scientists in 1928.  We are born with a certain number of hair follicles on our body. We do not get more.  Hair grows in a cycle and it may stop growing once its enters a resting phase but we cannot grow more than we have!  What is likely occurring to give this impression is that new hairs growing in are fine and tapered (almost like peach fuzz).  If these hairs are cut, then the fine tapered end is no longer there and it will appear coarser.  Shaving hair is only removing the surface hair and not impacting the hair matrix where the hair develops under the surface.  Often times waxing, plucking, and threading pull the hair out from underneath the surface.  When this occurs the hair has to reenter the growth phase and may start off fine and tapered again.  Ultimately as each hair grows longer the barrel of each hair gets wider and coarser (just like a blade of grass).
