I'm going to show you here how to clean the hairline with the clippers. This is a really handy tool to have, because in between salon appointments, most men end up with this untidy hairline. So, there is no guard on the clipper. It's just the basic blade. I pull the skin quite tight and in soft upward movements, just remove the hair. The biggest concern that I have when I'm telling people this is do not use the clipper in a downward motion. You must always use it in an upward motion, because that's going to refrain you from getting a hard line into the hair. That's how you clean the hairline with clippers.
