The BFRBs Nobody Talks About: Cheek Biting, Nail Biting, Lip Picking and More

Almost everything written about body-focused repetitive behaviors is about two of them. Hair pulling and skin picking. Those are real and they matter. But they are not the whole list, and if yours is not one of the famous two, you have probably spent years thinking your thing does not count.

It counts.

A body-focused repetitive behavior is any repetitive, self-directed behavior that damages the body and that you struggle to stop. The behavior usually gives you something in the moment. Relief. Stimulation. A way to discharge tension you did not even know you were holding. That description covers a lot more than hair and skin.

Here are the ones that rarely get named.

Cheek and lip biting

Biting the inside of your cheek or your lips has a clinical name, morsicatio, and it is far more common than people realize. Maybe you run your tongue along a rough spot and then you cannot leave it alone until it is raw. Maybe you do it in meetings, in the car, while you scroll. Most people who do this have never once connected it to anything other than a nervous habit.

Nail biting

Nail biting gets brushed off as childish. It is not. Chronic nail biting has a name too, onychophagia, and for a lot of adults it is a full BFRB that follows the exact same loop as hair pulling. Boredom, tension, a rough edge you have to even out, and then you are past the quick and it hurts.

The rest of the list

There are more, and if yours is here, you are not alone and you are not the only one. Skin biting. Cuticle picking and biting. Nose picking to the point of damage. Tongue chewing. Pulling or picking at scabs. Pulling eyelashes or eyebrows rather than scalp hair. Cheek chewing paired with picking the skin around your nails.

Different behavior, same machine underneath.

Why the name matters

You might be wondering why any of this matters if it is "just" cheek biting. Here is why. Once you know your behavior belongs to a category that has a treatment, your options change completely.

The reason "just stop" has never worked is that these behaviors are not about the mouth or the nails or the skin. They are about what the behavior does for your nervous system in that moment. That is also why the treatment is the same across all of them. It is called Habit Reversal Training, and it targets the loop instead of relying on willpower.

I always say the behavior is the smoke. The function is the fire. Two people can both bite their cheeks, one because it soothes anxiety and one because they cannot leave a rough texture alone, and they need different competing responses even though the behavior looks identical.

What to do with this

If you saw your behavior on this list, that is a good thing. It means there is a proven path forward that you may have never been offered.

My workbook This Isn't a Habit walks you through Habit Reversal Training for any BFRB, not just the famous two. It helps you map your specific triggers and build a competing response matched to what your behavior actually does for you.

And if you want to work through it with support, I take clients one on one as an LMHC trained in HRT, the first line treatment for these behaviors.

Your thing counts. It always did.
