If you’re having trouble using the HairFin hair cutting tool, these are the most common issues and how to fix them.

Most problems come down to positioning and technique, and can be corrected quickly.

These tips will help you cut hair more evenly at home and get better results with the HairFin.

The guide isn’t stable

Make sure you slide the HairFin grip all the way back to the base of your fingers, with the front of the fin facing toward your fingertips.

The grip is designed so the bottom platform slides under your palm, helping keep the guide stable while you cut.

Correct way to mount HairFin hair cutting tool on hand

The hair doesn’t stay between my fingers

Don’t hold the HairFin between your finger joints.

Slide it all the way back to the base of your fingers. The guide is thin enough to fit comfortably while still allowing you to grip the hair securely.

I’m getting hair in between all my fingers

This is normal.

You can use all of your fingers to hold hair. As long as your hand is flat and parallel to the head, you can trim any hair extending above your hand.

I’m having trouble holding the guide while grabbing hair

Make sure the HairFin is positioned at the base of your fingers.

When properly placed, you should be able to open and close your fingers to grasp hair without the guide slipping.

The guide keeps slipping

Hold your hand parallel to the part of the head you are cutting.

The guide should be perpendicular to the head, not angled. Avoid pushing the guide into the head; it’s only there to show how far to pull your hand out.

I’m having trouble cutting my own hair

Self haircuts can be more difficult due to mirror coordination.

If you’re new to cutting your own hair or using HairFin, it may help to have someone assist you for your first cut.

I want an in-between length

The guides prevent cutting too short, but you can always cut slightly longer.

For a half size, place the guide as normal, then slide your hand up about ½ inch before cutting.

The guide feels awkward to use

This is normal at first.

HairFin is a new tool, and like any new skill, it takes practice. Take time to review instructional videos and practice positioning before cutting.
