Question

whats the need of eyebrows?

Answer 1

In case sweat is released from forehead, it prevents the sweat to enter in our eyes

Answer 2

Hey friend.. here is you answer...

Scientists aren't entirely sure why we kept this hair, but they have a pretty good guess. We know that eyebrows help keep moisture out of our eyes when we sweat or walk around in the rain. The arch shape diverts the rain or sweat around to the sides of our face, keeping our eyes relatively dry.

Their main function is to prevent sweat, water, and other debris from falling down into the eye socket, but they are also important to human communication and facial expression. It is common for people to modify theireyebrows by means of hair removal and makeup.
