The short stubble style of beard is arguably one of the most simple ones around. It can be achieved by growing facial hair for a few days after shaving. This type beard looks very short.
To maintain a short stubble successfully, use a trimmer and adjust it so that the built-in guard is set all the way back.
Any hair that grows below the Adam’s apple should be trimmed using a trimmer or razor.
If you have stubble all the way to your cheeks, you can trim or shave the hair just below your cheekbone.
