Shaving

Shaving does not cause terminal hair to grow back thicker (more dense) or darker. This belief is due to hair which has never been cut having a tapered end, whereas after cutting the edge is blunt and therefore thicker than the tapered ends; the cut hair appears to be thicker and feels coarser due to the sharper, unworn edges. The shorter hairs being less flexible than longer hairs also contributes to this effect.
