I'm going to show you how to cut hair with clippers.
I've placed a guard on the clipper. Soften and upward movement. So, again, it's an inward and an outward movement; unless you want a really short, short, short hair, you would always go in and out. I always just start around the bottom hairline first, and just in and out. If the hair is growing this way, you would take the clipper movement that way. Always start in tighter in the hairline and moving out.
That's how you start cutting hair with clippers.
