Hair-pulling disorder

What it is

Trichotillomania involves recurrent pulling of one's own hair (scalp, eyebrows, eyelashes or elsewhere) leading to hair loss, despite repeated attempts to reduce or stop. Pulling may be focused (in response to urges or tension, with relief or gratification after) or automatic (during reading, screens, or falling asleep, noticed only by the pile of hair). It usually begins around puberty and affects roughly 1-2% of people, more women than men in adulthood.

The shame is often heavier than the symptom: wigs, scarves, drawn-on eyebrows, avoided swimming, dermatologists consulted under cover stories. Sufferers commonly believe they are the only one. They are not, and it has a name and a treatment.

How common is it

Trichotillomania affects roughly 1 to 2 in every 100 people, and is more common in women than men by adulthood. It usually starts around the early teenage years, often between ten and thirteen, though it can begin earlier or later. Many people never tell anyone, so it is widely under-recognised, and the true number affected is likely higher than clinic records show. A smaller number of people also swallow the pulled hair, which can cause stomach problems and should always be mentioned to a doctor.

What causes it

There is no single cause. The tendency runs in families and overlaps with skin-picking disorder, which points to an inherited component. For many people, pulling becomes a way the body manages tension, anxiety, boredom, or strong feeling, giving brief relief that makes the habit hard to break.

It frequently sits alongside anxiety, depression, or obsessive-compulsive disorder. It is not a sign of vanity, attention-seeking, or weak will, and understanding these threads matters because they point to what treatment should address.

How it is diagnosed

There is no laboratory test. A clinician makes the diagnosis by talking with the person, looking for repeated hair pulling that leads to hair loss, repeated attempts to stop, and real distress or disruption to daily life. They will rule out skin and scalp conditions that can also cause hair loss, such as alopecia, and ask about any swallowing of hair.

Because the hair loss is visible, some people first see a dermatologist rather than a mental health professional. Good care brings the two together, so that the scalp and the urge are understood side by side.

How it is treated

Habit reversal training (HRT) is the core treatment: awareness training to catch the urge and the early hand movements, a competing response the hands perform instead until the urge passes, and stimulus control to change the high-risk situations (fiddle objects, gloves at trigger times, changed routines). Acceptance-based additions help with the urges themselves. No medication is approved specifically for trichotillomania; clinicians sometimes use medication for co-occurring anxiety or depression, but HRT carries the evidence. Skin-picking disorder, its close cousin, responds to the same approach.

Hair-pulling in the African context

Reliable figures across Africa are scarce, though South African researchers have been among those advancing understanding of this condition. What is consistent is concealment. People cover the loss with headscarves, wigs, hats, or drawn-on brows, and the pulling is often misread as a bad habit, nerves, or given a spiritual explanation, none of which helps a person stop.

Specialist services are unevenly spread and can be hard to reach outside larger towns. The most useful change is to treat hair-pulling as what it is, a recognised and treatable health condition that responds to the right help, rather than a flaw of character to be hidden or scolded.
