Is Hair Pulling a Sign of ADHD or Trichotillomania?

Hair pulling is not a core symptom of ADHD, but the two conditions overlap more often than you might expect. About 29% of people with trichotillomania (the clinical term for compulsive hair pulling) also have ADHD. That’s a significant link, and it stems from shared brain chemistry and the way both conditions affect impulse control.

How ADHD and Hair Pulling Are Connected

ADHD and hair pulling are separate diagnoses, but they share underlying biology. Both involve disruptions in the brain’s dopamine and serotonin systems, the chemical messengers responsible for impulse control, reward processing, and repetitive motor behaviors. When these systems are out of balance, the brain struggles to hit the brakes on urges, whether that’s blurting something out in a meeting or reaching up to pull a strand of hair.

Research on people with trichotillomania has found statistically significant impairment in inhibitory control compared to people without the condition. That same difficulty with inhibition is one of the hallmark features of ADHD. So while hair pulling isn’t caused by ADHD directly, the same wiring issues that make it hard to resist impulses in ADHD can also make someone more vulnerable to developing repetitive behaviors like hair pulling.

Hair Pulling as Self-Soothing

For many people with ADHD, hair pulling serves a specific purpose: it’s calming. The ADHD brain is often either understimulated or overwhelmed, and repetitive physical behaviors can act as a regulator. Some people describe feeling a tingling sensation at the hair root that creates an urge to pull, and the act of pulling provides a brief moment of relief or satisfaction.

This is especially common in children with ADHD. UC Davis Health notes that hair pulling and similar repetitive behaviors occur more frequently in kids with ADHD, often as a form of self-soothing. A child might pull hair while doing homework, watching TV, or lying in bed, particularly during moments of boredom, frustration, or anxiety. The behavior can become automatic, happening outside of conscious awareness, which makes it harder to interrupt.

Two Separate Conditions, Not One Symptom

It’s important to understand what hair pulling is and isn’t in relation to ADHD. The diagnostic criteria for trichotillomania treat it as its own condition, classified alongside obsessive-compulsive disorders. It’s not listed as a symptom or subtype of ADHD. When someone has both, clinicians consider them co-occurring conditions rather than one causing the other.

That said, ADHD-related impulsivity can make hair pulling harder to control once it starts. If you already have the urge to pull, a brain that struggles with impulse regulation is less equipped to resist it. This is why treating the ADHD component sometimes reduces the hair pulling as well, though not always.

What Else Overlaps With Hair Pulling

ADHD is far from the only condition that co-occurs with trichotillomania. The most common comorbidities paint a picture of a condition deeply tied to emotional regulation:

  • Anxiety disorders: 53% of people with trichotillomania
  • Depression: 45%
  • ADHD: 29%
  • PTSD: 29%
  • OCD: 29%

Anxiety is actually the most common co-occurring condition, which makes sense given that many people describe hair pulling as a response to anxious feelings. If you’re pulling your hair and also have ADHD, it’s worth considering whether anxiety might also be playing a role, since anxiety is frequently underdiagnosed in people with ADHD.

ADHD Medication and Hair Pulling

Stimulant medications prescribed for ADHD have a complicated relationship with hair pulling. In most cases, improving focus and impulse control with medication can reduce repetitive behaviors. But in rare instances, stimulants can trigger hair pulling in someone who never had the behavior before.

One documented case involved a 12-year-old girl who developed hair pulling shortly after starting a stimulant medication for ADHD. She reported that the medication made her feel anxious, and pulling her hair relieved that anxiety. When her doctor switched her to a non-stimulant medication (guanfacine), the hair pulling stopped completely within weeks and didn’t return over a full year of follow-up. This appears to be an uncommon reaction, but it illustrates why new repetitive behaviors that emerge after starting or changing ADHD medication are worth flagging to your prescriber.

Recognizing the Pattern

If you or your child has ADHD and you’re noticing hair pulling, a few patterns can help you understand what’s driving it. Hair pulling that happens during periods of understimulation, like sitting through a long lecture or waiting in line, points toward sensory seeking. Pulling that ramps up during stressful moments suggests an anxiety or emotional regulation component. And pulling that seems completely automatic, where the person doesn’t realize they’re doing it until they see the hair in their hand, is consistent with the kind of habitual behavior that thrives when attention regulation is impaired.

Many people experience a combination of all three. The most effective behavioral approaches for hair pulling focus on building awareness of when and where the pulling happens, then substituting a competing action, like squeezing a stress ball or running fingers over a textured surface. For people with ADHD, addressing the underlying attention and impulse difficulties often makes these behavioral strategies more effective, because the person is better equipped to notice the urge before acting on it.
