Trichotillomania: will hair grow back after hair pulling?

Evidence and service information checked, October 2026.

If you pull at your hair while reading, working, watching television or trying to settle an uncomfortable urge, you are not alone. Hair-pulling disorder is a recognised condition, not a failure of willpower. The most useful first investment is an accurate assessment and help with the pulling itself, not a package promising to regrow hair while the cause continues.

Will hair grow back after trichotillomania?

Hair can regrow after pulling stops if the follicles remain capable of producing hair, but regrowth is not guaranteed and cannot be timed accurately from a photograph. Repeated pulling can damage the skin and follicles, and scarring can permanently affect growth. The priority is to reduce pulling, check the scalp and treat any damage or other cause of hair loss.

Trichotillomania involves recurrent hair pulling that causes hair loss, repeated attempts to reduce or stop it, and significant distress or impairment. A clinician also considers other explanations. Not everyone who occasionally touches or twirls their hair has the disorder.

What matters most

• Hair-pulling can be automatic, focused on an urge, or a mixture of both.
• Therapy with habit reversal training is a main treatment approach.
• A scalp examination can check for broken hairs, inflammation, infection or scarring and consider other diagnoses.
• Minoxidil and PRP do not treat the pulling behaviour itself.
• Swallowing hair can cause serious digestive complications and needs medical advice.

Ask The London PRP Clinic about a scalp assessment if you need help understanding the hair loss. Make clear that pulling may be involved so assessment and onward care can be appropriate. This does not imply the clinic provides specialist psychological therapy.

How can hair-pulling look different from pattern hair loss?

Pulling can affect the scalp, eyebrows, eyelashes or other areas. There may be irregular patches, short broken hairs of different lengths or a favourite area that is repeatedly touched. Some people pull without noticing until they see hair on their clothes or desk.

Pattern hair loss typically follows a different distribution and mechanism, although more than one condition can coexist. Smooth patches, scaling, infection, traction from styling and scarring disorders also need considering. An online image comparison cannot reliably distinguish them.

Tell the clinician about pulling even if it feels embarrassing. It is useful information, not something you need to conceal to deserve care. If a child or teenager is affected, approach it without punishment or shaming and seek age-appropriate help.

What is habit reversal training?

Habit reversal training helps you recognise the situations, sensations and movements that precede pulling and practise a competing response. For example, a therapist may help you notice the hand moving towards the hair and choose a different action that makes pulling less likely.

It is more structured than being told to "just stop". Treatment can include awareness training, changes to cues and environments, and support with difficult urges or emotions. Other approaches, including acceptance-based or cognitive therapies, may be used alongside it.

A meta-analysis of behaviour therapy trials supports benefit, although study sizes and treatment approaches vary and relapse can occur. It is reasonable to ask a therapist about their experience with body-focused repetitive behaviours and habit reversal specifically, rather than assuming any general counselling course is equivalent.

Mayo Clinic describes habit reversal training as the main treatment for trichotillomania. Assessment can also identify anxiety, depression or another problem that deserves treatment in its own right.

What can I try while arranging help?

Start by noticing, not judging. For a week, record where you are, what your hands are doing, the activity and whether there was an urge or you noticed only afterwards. Short notes can reveal a pattern without turning the day into constant self-monitoring.

Consider a practical barrier or alternative activity that is comfortable and safe, such as keeping your hands occupied during a predictable trigger. A trained therapist can help choose strategies that fit your pattern. An approach that helps someone who pulls while studying may not help someone whose pulling is driven by searching for a particular hair texture.

Avoid harsh chemicals, aggressive scalp rubbing and repeated checking that irritates the skin. Be cautious about expensive devices or supplements sold with a cure claim. Support from a trusted person can help if it is wanted; policing, teasing or punishment usually makes it harder to speak openly.

If distress is severe or you feel unsafe, seek urgent mental-health help. Immediate danger or a medical emergency requires 999.

Do medicines help?

Medication may be considered for selected people or for coexisting conditions, but there is no one medicine that reliably cures hair-pulling disorder. Evidence varies and potential adverse effects matter.

N-acetylcysteine is often promoted online because some studies suggest benefit. That does not make every supplement brand, dose or use in a child established or safe. Do not start a high-dose supplement or use someone else's psychiatric medicine based on a social-media recommendation.

Discuss options with a clinician who understands the condition, including what evidence applies to your age and circumstances, what improvement would count and how treatment would be reviewed. Psychological care should not be skipped simply because a tablet is easier to buy.

How long does regrowth take?

There is no defensible universal deadline. Follicle damage, the area involved, continued pulling and other hair conditions affect the outcome. A clinician may be able to distinguish broken hairs and early regrowth from signs that need dermatology review, but photographs alone cannot promise complete recovery.

Consistent photographs taken at intervals can be useful. Daily inspection or pulling a hair to test its strength can become unhelpful and may reinforce the cycle. Agree a review schedule that supports recovery rather than feeding repeated checking.

A scarred, shiny area, persistent redness, pain, pustules or signs of infection deserve assessment. Earlier evaluation can matter when a different scarring disorder is possible.

Does PRP treat trichotillomania?

PRP should not be presented as an established treatment for the pulling disorder. It does not teach a competing response or remove the urge to pull. Continuing mechanical damage can undermine any regrowth plan.

Evidence from androgenetic alopecia cannot simply be transferred to hair loss caused by repeated pulling. If you also have pattern hair loss, that separate diagnosis can be discussed on its own merits. Any proposed procedure should explain which condition it is intended to address, the uncertainty and why it is worth considering.

A responsible consultation may end with advice against PRP and a recommendation for dermatology or psychological care. That is a useful outcome, not a failed sale.

Request an assessment before buying a regrowth course. As checked in October 2026, the clinic lists a £150, 30-minute consultation with scalp assessment and trichoscopy, with £50 credited towards treatment under the listed arrangement. Confirm whether the service is suitable for your concern and any onward-referral arrangements before booking.

What if I swallow the pulled hair?

Tell a doctor. Swallowed hair can collect in the digestive tract and form a hairball that may require medical or surgical treatment. Abdominal pain, vomiting, difficulty eating, weight loss or signs of obstruction need prompt medical assessment. Severe pain, persistent vomiting, collapse or another emergency should not wait for a hair-clinic appointment.

This is a medical safety issue, not a reason for shame. Being clear about swallowing hair helps the clinician choose the right assessment.

Questions people often ask

Is it caused only by stress?

No. Stress can be relevant, but pulling can also occur during boredom, concentration or without a clearly noticed emotion. A simple stress explanation may miss the treatment needed.

Can I have both trichotillomania and pattern hair loss?

Yes. A careful history and scalp assessment can help separate the contributions rather than treating every thin area as the same problem.

Will shaving my head cure it?

It is not a proven cure for the disorder. Appearance choices may help some people manage a period of recovery, but they do not replace assessment and therapy.

Should I hide it until my hair grows back?

You do not need visible regrowth before asking for help. Explain the pulling and its effect on your life so care can address both the behaviour and the scalp.

Contact The London PRP Clinic for an appropriate scalp-assessment enquiry. For treatment of the pulling behaviour, ask your GP or a suitably trained mental-health professional about habit-reversal-based care.
