You can sweep your hair either on the right side or the left side of your head. But which one will look good might be challenging to find out. There is an easy way to do that. All you need to do is, find the direction of the cowlick spirals, which means the swirl close to your temple. If this swirl moves in a clockwise direction, you need to sweep your hair to the left. Just like this, if the cowlick spiral moves in an anticlockwise direction, then swapping needs to be done towards the right side of your head.
