This is how to cut side bangs.
I've wet the hair down because I like to have a little bit more control over the hair when I'm cutting. And, we're going to work from her left side to her right side. Working on a slight angle going down.
So, I see there's a cowlick right here. That's going to be my starting point. So, I'm just going to let the hair fall exactly where it wants to fall. I'm going to place my scissors in at an angle and gently cut down from shorter to slightly longer as you get toward the cheekbone.
And you'll notice it comes towards the cheekbone there. And I'm just going to include this last piece of hair that's just around the cheekbone.
So in effect, what you're working on is just one diagonal line. Which gives you a side angle bang.
