Trichotillomania: Understanding Compulsive Hair Pulling and What Treatment Looks Like

What is trichotillomania and how is it classified?

Trichotillomania (also called TTM or "trich") is classified in the DSM-5 as an obsessive-compulsive and related disorder — in the same diagnostic family as skin picking (excoriation disorder) and nail biting 1Ref 1National Institute of Mental Health (2023).Obsessive-Compulsive Disorder (OCD).DSM-5 classification of TTM in the obsessive-compulsive and related disorders spectrum; role of medication and behavioral therapy in OCD-spectrum conditions; self-blame worsening the cycle. Pulling often occurs in two patterns: automatic pulling that happens without full awareness (often while watching television, reading, or falling asleep) and focused pulling that is deliberate and accompanied by tension before the pull and relief afterward. Most people experience a mix of both.

Hair loss from TTM is typically patchy and irregular, with hairs of varying lengths because the pull cycle is ongoing. It most often affects the scalp, eyebrows, or eyelashes. TTM can begin in childhood or adolescence and, without treatment, tends to wax and wane rather than resolve on its own. The lifetime prevalence is estimated at 1–2% of the population.

Why willpower alone rarely works

TTM sits in the brain's habit and reward circuitry. The pulling provides real neurological relief from tension or emotional discomfort, which reinforces the behavior regardless of conscious intent to stop. Telling someone with TTM to simply stop is like telling someone with a phobia to simply not be afraid — the conscious effort does not rewire the underlying loop.

This is why the most effective treatments are behavioral: they work with the neurology of habit rather than against it through willpower alone. Understanding this framing can reduce self-blame, which itself tends to worsen the pulling cycle 1Ref 1National Institute of Mental Health (2023).Obsessive-Compulsive Disorder (OCD).DSM-5 classification of TTM in the obsessive-compulsive and related disorders spectrum; role of medication and behavioral therapy in OCD-spectrum conditions; self-blame worsening the cycle.

What does treatment look like?

The most evidence-supported treatments for TTM are behavioral. Habit Reversal Training (HRT) involves increasing awareness of pulling urges and behaviors, identifying specific settings and triggers, and substituting a competing response — something physically incompatible with pulling, such as squeezing a textured object — when the urge arises 2Ref 2Gupta S, Gargi PD (2012).Habit Reversal Training for Trichotillomania.Habit Reversal Training as an effective treatment for trichotillomania even after pharmacotherapy failure; awareness, competing response, and stimulus-control components.

Comprehensive Behavioral Treatment (ComB) expands HRT to include a full assessment of sensory, cognitive, affective, motor, and environmental factors that drive each person's pulling pattern. A randomized clinical trial of ComB found statistically significant reductions in self-reported symptom severity compared to a control condition, with 27% of ComB participants achieving complete abstinence from pulling at 12 weeks versus 0% in the control group 3Ref 3Carlson EJ, Malloy EJ, Brauer L, Goldfinger Golomb R, Grant JE, Mansueto CS, Haaga DAF (2021).Comprehensive Behavioral (ComB) Treatment of Trichotillomania: A Randomized Clinical Trial.ComB RCT: 27% of participants achieved complete pulling abstinence at 12 weeks vs. 0% in control; personalized sensory/motor/affective assessment; stronger outcomes with experienced clinicians.

Therapy is typically conducted with a therapist trained in body-focused repetitive behaviors (BFRBs), often in weekly sessions. Medication is sometimes added when anxiety or OCD features are prominent, but medication alone without behavioral work has more limited evidence for TTM specifically 1Ref 1National Institute of Mental Health (2023).Obsessive-Compulsive Disorder (OCD).DSM-5 classification of TTM in the obsessive-compulsive and related disorders spectrum; role of medication and behavioral therapy in OCD-spectrum conditions; self-blame worsening the cycle.

Can hair grow back after trichotillomania?

In most cases the follicles remain intact and regrowth is possible once pulling stops or decreases significantly. Patchy areas often begin filling in within a few months of reduced pulling. The exception is in cases where pulling has been very long-standing and forceful — the follicles can occasionally be permanently damaged, though this is less common than in other causes of scarring alopecia.

A dermatologist can assess follicle viability and provide reassurance or additional support. Some people find that addressing cosmetic appearance in the interim — with wigs, hairpieces, or scalp covers — helps reduce the shame that can fuel more pulling, so the cosmetic and behavioral tracks can support each other.

How to find the right help

The TLC Foundation for Body-Focused Repetitive Behaviors (bfrb.org) maintains a therapist directory of clinicians trained specifically in BFRB treatment and is a trusted starting point. You do not need a psychiatrist referral or a separate diagnosis to begin — a therapist trained in HRT or ComB can work with you directly.

Asking for help can feel embarrassing; it helps to know that TTM affects a meaningful portion of the population and that clinicians who specialize in it understand the condition well and approach it without judgment. If OCD features, depression, or anxiety are prominent alongside the pulling, a formal psychiatric evaluation helps determine whether medication alongside therapy is appropriate 1Ref 1National Institute of Mental Health (2023).Obsessive-Compulsive Disorder (OCD).DSM-5 classification of TTM in the obsessive-compulsive and related disorders spectrum; role of medication and behavioral therapy in OCD-spectrum conditions; self-blame worsening the cycle.

For people with sensory processing differences — common in ADHD or autism spectrum presentations — pulling may be partly driven by sensory stimulation. ComB therapy addresses this with sensory substitutes, which may be more effective than standard HRT alone in these cases 3Ref 3Carlson EJ, Malloy EJ, Brauer L, Goldfinger Golomb R, Grant JE, Mansueto CS, Haaga DAF (2021).Comprehensive Behavioral (ComB) Treatment of Trichotillomania: A Randomized Clinical Trial.ComB RCT: 27% of participants achieved complete pulling abstinence at 12 weeks vs. 0% in control; personalized sensory/motor/affective assessment; stronger outcomes with experienced clinicians.
