How to Do the Business Haircut 

Using your Wahl clipper, select an attachment guard that will shorten the hair but not leave it too short. The #5 guard (5/8") is a frequent selection. If you find that the hair should be cut shorter after the first or second pass, change to a lower numbered attachment guard.

Using an upward rocking motion, cut around the ear and then continue to the back of the head, all the way to the other ear (Section 2). Comb the hair as you go. It will give you a better idea of how the hair naturally lies.

Switch to a higher attachment guard. A #8 (1") works well for the top of the head. From the back, comb the hair to see how it naturally falls. Begin to cut, rolling the clipper from front to back to help cut down on bulk.

Now blend the sides, using the same upward motion rolling technique over the rim of the head (Section 3) where the sides meet the top.

Using your Wahl trimmer or the inverted clipper technique, trim the neckline and ear arches.
