It is far more common than most people realise, and it responds to the right kind of help.

Trichotillomania is a recognised mental health condition in which a person repeatedly pulls out their own hair, most often from the scalp, eyebrows or eyelashes, and finds it very difficult to stop. It is classified among the body-focused repetitive behaviours, sits close to obsessive-compulsive disorder, and is not a habit someone can simply decide to abandon. The most effective help is a specific behavioural therapy called habit reversal training, available through the NHS.

What does trichotillomania actually look like?

The condition presents as areas of hair loss that a person has created themselves, usually without fully intending to. The pattern is distinctive once you know what to look for.

• Patches with an irregular, uneven outline rather than a smooth circle.
• Hairs of markedly different lengths within the same patch, because some have been pulled recently and others are growing back.
• Broken-off stubble that feels bristly rather than a genuinely bare, smooth patch.
• Often one side more than the other, favouring the dominant hand.
• Commonly affecting eyebrows and eyelashes as well as the scalp.

The pulling itself varies enormously. For some people it is automatic and barely conscious, happening while reading, driving or watching television. For others it is focused and deliberate, often following a build-up of tension that pulling briefly relieves. Many people experience both at different times, and the two respond to slightly different strategies.

How is trichotillomania different from alopecia areata?

Alopecia areata and hair pulling both produce patches, and they are frequently confused, but they look and feel different on close inspection.

This is a distinction a GP or dermatology service will make properly, and it matters because the help is completely different. Our separate guide to alopecia areata, its symptoms and what helps covers the autoimmune side in detail.

What causes trichotillomania?

There is no single cause, and the honest state of the evidence is that several factors contribute rather than one explaining everything.

It is not caused by bad parenting, weak character or attention-seeking. That deserves saying plainly, because those explanations still circulate and they actively delay people from asking for help.

What research does point to is a combination of genetic predisposition, differences in the brain circuits involved in habit formation and impulse regulation, and emotional triggers. Stress, anxiety, boredom and periods of being understimulated are all common precipitants. It is grouped with obsessive-compulsive and related disorders in current classification systems, and it frequently occurs alongside anxiety or low mood, which is one reason a proper assessment is worth having.

Onset is most often in early adolescence, around ages 10 to 13, though it can begin in early childhood or in adulthood. Childhood-onset pulling in very young children often resolves on its own, whereas pulling that starts in adolescence is more likely to persist without help.

What genuinely helps?

The approach with the strongest support is a structured behavioural therapy, and the specific one to ask for by name is habit reversal training.

Habit reversal training

Habit reversal training has three components. Awareness training builds a detailed picture of when and where pulling happens, because much of it is automatic and invisible to the person doing it. Competing response training establishes an alternative action, incompatible with pulling, to perform when the urge arrives, such as clenching the fists for a minute. Social support brings in someone trusted to encourage the new response without nagging. A 2023 review in Clinical and Experimental Dermatology describes it as the leading psychotherapeutic approach for body-focused repetitive behaviours.

Broader talking therapies

Cognitive behavioural therapy more generally, and acceptance and commitment therapy, are both used, often combined with habit reversal. Where anxiety or low mood sits underneath the pulling, addressing that changes the picture considerably.

Getting to it through the NHS

Start with your GP, who can refer you onward. In England you can also self-refer to NHS talking therapies without going through a GP. Waiting times vary, so it is worth asking about both routes.

Which practical strategies help day to day?

These are not a substitute for therapy. They are the things that make the gap between now and an appointment more manageable, and they work best alongside a proper programme.

1. Track it before you try to change it. A simple note of time, place, mood and activity for two weeks reveals patterns nobody notices from memory. Most people discover their pulling is far more situational than they thought.
2. Put a barrier in the way. Plasters on fingertips, a hat, a headscarf or gloves in the evening make automatic pulling conscious, which is often enough to interrupt it.
3. Give your hands something else. A fidget object, textured putty, a stress ball or knitting occupies the same hands during the high-risk activities you identified in your tracking.
4. Change the environment, not just the intention. Remove tweezers and mirrors from the places pulling happens. Many people pull in the bathroom under bright light, and simply not going in there alone at night helps.
5. Handle the hair you have gently. Wide-tooth comb, no tight styles, no aggressive towel drying. Broken hair from rough handling makes the patches look worse and is discouraging.
6. Be kind about relapses. Progress is not linear. A bad week is data about a trigger, not evidence of failure.

Will the hair grow back?

In most cases, yes. A follicle that has had a hair pulled from it is generally undamaged and will produce a new hair, entering the growing phase again over the following weeks and months. Expect the first visible stubble within a few weeks of stopping and meaningful coverage over several months, since scalp hair grows at roughly one centimetre a month. Our explanation of the hair growth cycle sets out the timings.

There is an important exception. Pulling repeatedly from the same area over many years can cause scarring and permanent loss of the follicle, and hair will not come back from a follicle that has been destroyed. This is uncommon but it is real, and it is the strongest practical argument for seeking help sooner rather than waiting to see whether it passes.

Hair coming back may look a slightly different texture or colour at first. That usually settles.

What about children who pull their hair?

Hair pulling in very young children is relatively common and often self-limiting, sometimes functioning as a self-soothing behaviour much like thumb sucking. It frequently fades without any formal intervention.

It still warrants a conversation with your GP, for two reasons. First, to rule out other causes of childhood hair loss, several of which look similar and need different care. Second, because pulling that persists into adolescence responds much better to early support. Our guide to the causes of hair loss in children covers the alternatives a GP will consider.

Do not punish or shame a child for pulling. It reliably makes the behaviour more secretive rather than less frequent.

When should you see a GP?

Speak to your GP if any of the following apply.

• You are pulling your hair and cannot stop, whatever you have tried.
• The pulling is affecting your work, your studies, your relationships or how willing you are to leave the house.
• You are swallowing the hair you pull. This can form a mass in the digestive tract and needs medical attention promptly.
• Your scalp is sore, bleeding, scabbed or infected.
• There is anxiety, low mood or self-harm alongside the pulling.
• Your child is pulling and it has continued for more than a few months.

Frequently asked questions

Is trichotillomania a mental illness?

Yes. It is a recognised mental health condition, grouped with obsessive-compulsive and related disorders. That classification is what gives people access to the right therapy, and it is not a judgement about character or willpower.

Can hair pulling be resolved for good?

Many people reach a point where pulling stops entirely or becomes rare and manageable, particularly with habit reversal training. Others find it comes and goes with stress across their life. Both outcomes are common, and neither means someone has done it wrong.

Does hair grow back after trichotillomania?

Usually yes. The follicle is generally undamaged and produces a new hair within weeks. The exception is very long-standing pulling from the same spot, which can scar the follicle and cause permanent loss, so getting help early genuinely matters.

Is hair pulling caused by stress?

Stress is a common trigger rather than the whole cause. Genetics, differences in how the brain regulates habit and impulse, and emotional state all contribute. Plenty of people also pull when bored or understimulated rather than stressed.

How do I help a child who pulls their hair?

Stay calm, avoid punishment and do not draw constant attention to it. Speak to your GP so other causes of hair loss can be ruled out and support can be arranged. In young children the behaviour often fades on its own.

Will a hair growth product help?

No. Cosmetic products act on the hair and scalp, not on the behaviour, so they cannot address the cause. Once pulling has stopped, gentle handling helps the hair coming back look its best, but that is a supporting role and nothing more.

Is hair pulling disorder rare?

It is more common than most people assume, and considerably more common than the number of people who mention it, because it carries a lot of shame. Most people conceal it for years before telling anyone, including their GP.

Can medication help?

Some people are offered medication, usually where anxiety, low mood or obsessive-compulsive symptoms sit alongside the pulling. This is a decision for a doctor who knows your full history, and it is normally considered alongside behavioural therapy rather than instead of it.

The bottom line

Trichotillomania is a recognised condition with a specific, evidence-backed behavioural therapy behind it, and the single most useful thing anyone reading this can do is speak to a GP or self-refer to NHS talking therapies. Tracking triggers, putting physical barriers in the way and giving your hands something else to do all help in the meantime.

The hair usually comes back once the pulling stops. The shame around it is the part that keeps people stuck longest, and it is entirely undeserved.
