Using an Electric Trimmer

Trim the hair on the front and back of your bicep. Position your electric trimmer so the flat edge is against your skin, and move it in small sections to trim your hair. Oftentimes, the bicep is where uneven patches of hair grow. Make sure you follow the opposite direction of your hair growth. The hair can grow in different directions around your bicep.

Work your way to your forearms to complete your trim job. Once you trim the hair on your biceps, continue trimming down your arms to your forearms. You may have to switch directions again, based on the way your hair grows. Once you trim the hair around your wrist, you are finished.

Trimming with Scissors

Comb the arm hair the opposite way of the hair growth. Use a fine-tooth comb to brush the hair backwards several times. Do this until the hair is mostly vertical, so you can easily see its total length. Combing your hair the opposite direction makes it easy for you to see the hair and trim it to your desired length.

When trimming your hair with scissors, starting at your forearm ensures the rest of your hair will be the close to the same length.

Comb and trim your arm hair until you achieve your desired look. As you trim your hair, it may make it easier if you comb up your hair again. That way, you can easily see the length. After you comb the hair, trim it in small sections until you are comfortable with your outcome. Take your time as you do this to avoid messing up. As you trim, check to make sure you don’t have any high or low spots in your arm hair. You want your hair to all be close to the same length.

Comb the hair back down in the direction of the hair growth. When you are finished trimming your arm hair, use your fine-toothed comb to smooth your hair back against your arm. Combing your hair again also makes makes it easier to notice any long patches or uneven sections.
