If you’re looking to rock a Top Knot, the first step is to make sure that you have enough hair to tie up in the first place. You’ll need at least 6-10 inches. If you currently have a buzz cut, expect to be growing it out for six months before you can pull off this look. Tell your barber to cut all the hair on the sides and back of your head with clippers, not scissors. Cut correctly, and your hairstyle will achieve the drama a top knot demands. The last step is to gather up all the hair on top and tie it up with a hair tie. Standard placement is the top center of your head.
