This is a very common myth, with no basis in fact. Shaving has been shown since 1928 not to cause hair to come in thicker.
Hairfacts: shaving medical data
Think of shaving like mowing grass. When grass is long and tapered on the ends, it’s pretty soft, but when you cut it low and with a flat surface, it feels thicker and fuller (like a putting green). Same is true for hair.
Another way to think about it is like a forest. The tall trees are soft and tapered at the top, and they bend in the wind. But if you clear cut the forest leaving only thick flat stumps, they don’t budge. That’s what shaving does.
As far as waxing, there may be a very minuscule change in hair growth from waxing, but it’s not something you’re going to notice. In fact, some people think waxing is causing permanent reduction in hair growth, but this is basically an optical illusion, like the “thicker” hair from shaving.
The advantage of waxing is that regrowing hairs are tapered, so the don’t feel as rough as stubble from shaving.
