Sideburns can flatter your face and enhance your features; long sideburns can hide a prominent chin and short sideburns can help bring out a weak chin. Trimming your facial hair to create sideburns can be challenging, because the left and right side of your face are not symmetrical. You may end up with uneven sideburns. To correct uneven sideburns, your need to take your time, because otherwise you may end up with sloppy results.

Stand in front of a mirror in a well-lit room. Look straight into the mirror; avoid moving your head up, down or sideways.

Brush your sideburn hairs in the direction of the hair growth.

Place both of your index fingers horizontally along the bottom edges of your sideburns. If your sideburns are even, both fingers will be at the same height. If one finger is higher than the other, your sideburns are uneven.

Place your trimmer on the longer sideburn. Position it on the excess hairs close to the bottom edge; you want to trim the length little by little to avoid removing too much of it.

Trim the hairs in the direction of the hair growth. Stand back from the mirror and examine your progress. Place your fingers horizontally along the bottom edge of your sideburns to check if they are even. If not, trim the longer sideburn some more, until both sides are even.

Wipe away the trimmed hair and apply aftershave to soothe your skin.
