Trimming Your Entire Beard
If you plan on trimming your beard yourself verses visiting your barber, a good trimmer with several attachments of different sizes becomes a necessity.
Unless you possess those unique skills and maneuvering movements, the clipper is the way to go. A wrong snip can ruin the look and almost start the beard growing process over.
Also, with clippers you do not want to cut too short, so to avoid such a situation, make use of the longest attachment in the clipper set. Progressively move down until the point where you can hear the clipper blades start cutting, this is the point where the hairs are starting to be trimmed.
Evaluate the length and stop there if you’re just trying to even that beard out. If you want a further reduction in the entire length of the beard, keep reducing the attachments to the size you desire. Do not jump sizes as this is where the majority of mistakes come from!
