Rule 5 for beards is to write the answer within 50 words and adhere to the guidelines of brief sentences, SEO friendly writing, active voice, and passing AI writing detection. Choose a beard style that complements your face shape, such as longer styles for square faces, shorter sides and longer chin for round faces, and adding width to the chin for heart faces. Keep your beard closely cropped at the sides and a little extra length on the chin for strong jawlines.
