How to Cut your Hair to have an Undercut

Rich in history and style, the undercut is a classic that started in 1910 and resurfaced in 2010. Undercuts allow you to personalize your haircut depending on your desired look, it can either be connected or disconnected, parted or not.

What you will need:

  • Wahl clipper
  • Wahl trimmer
  • #1 (1/8") guide comb attachment
  • #2 (1/4") guide comb attachment
  • #5 (5/8") guide comb attachment

How to Do an Undercut Haircut Step-by-Step

  • 1

    Dampen your hair with the spray bottle. Comb your hair down so it is lying straight.

  • 2

    Comb the hair on the top of your head (section 4 of the head) into a small horseshoe shape and use a hair clip to hold it in place or hold it to the side with your non-dominant hand.

    Note: The horseshoe-shaped section of hair should be at least 5 inches in length to slick back or sweep to one side.

  • 3

    Depending on preference, use a #1 (1/8") or #2 (1/4") guide comb on your Wahl clipper, begin clipping the back of the neck and under the rim on the head (sections 1 and 2) making sure to not clip into the rim or top of the head (sections 3 or 4).

    • For a connected undercut: Blend the back of the neck and under the rim (sections 1 and 2) with the rim of the head (section 3) using a guide comb that is two numbers higher than the one you used previously. For example, if you used a #1 (1/8"), use a #3 (3/8"). This gets a result that is similar to a high & tight haircut.
    • For a disconnected undercut: Leave the hair as is without blending and cut the hair at the rim of the head (section 3) using the same guide comb used on the back of the neck and sections 1 and 2.
  • 4

    Remove the hair clip from the top of your head (section 4) or let it fall flat from your hand. Comb the hair flat.

  • 5

    If you are planning to part the hair on the side, leave the hair closest to the part slightly longer (at least 6 inches). If you are planning on combing the hair straight back, there is no need to vary the length.

  • 6

    For a connected undercut, attach guide comb #5 (5/8") and use an upward rocking motion just around the perimeter of the horseshoe.

    •  If choosing a disconnected undercut, skip this step.
  • 7

    Remove the guide comb and use the clipper-over-finger technique to finish off the top.

  • 8
  • 9

    Use a dab of Wahl Hair Pomade and style to the side (if parted) or straight back.
