Nerve photo (Schuster, 1992)

Ever wonder why hair removal hurts so much? Here's why! Look at all those nerves in this microscopic photo of a hair root!

The reason tweezing, waxing, laser, and electrolysis are sometimes painful is because each hair has a bundle of nerves surrounding the lower follicle. Plucking a hair tears the tissue near the root, which can set off pain sensation in these nerves. The energy required to remove hairs with laser and electrolysis can also cause these nerves to register pain.

The reason so-called "painless" methods such as electric tweezers and "transdermal" methods do not usually hurt as much is because they do not deliver enough energy into the follicle to cause lasting damage, or even to stimulate the nerves in the area.
