Functions of Eyebrows

Functions of Eyebrows

Eyebrows have changed with human evolution to provide two major functions.

Firstly they prevent sweat from running into the eyes. Even the thinnest of eyebrows are able to do this, so it’s never a good idea to remove too much.

Secondly, and most importantly, they are an important part of expressing emotion and body language. Sit in front of the mirror and make expressions of happiness, sadness, fear and anger. Now do the same but with the eyebrows covered up. The difference is enormous, and explains why people with botoxed foreheads look so strange in conversation.

Eyebrow hairs tend to get thicker and longer as we age, especially in men. The best way to deal with them is to trim the hairs a little, rather than remove them.
