Re: Is eyebrow plucking bad for skin or nerves?
Tweezing brows will not damage your brain. There are a lot of nerves in that area, but hairs are not connected to nerves. If you do an image search for "skin cross section" you will find diagrams showing where nerve endings are in relation to hair follicles.
But, tweezing can damage skin. It can cause hyperpigmentation and ingrown hairs. Also, with the brows, the eyelid skin is different that other skin on the face and body. It's very much like scar tissue and easy to damage. This is why some people who over tweezed their brows in their youth end up with sparse brows.
