Researchers studied 40 people with trichotillomania (a condition where people repeatedly pull out their own hair) and compared them to 400 people without the condition. They found that people with hair-pulling disorder were much more likely to have other mental health problems like anxiety, depression, and obsessive-compulsive disorder. The study also found connections to alcohol problems, vitamin D deficiency, and difficulty with daily activities. This research helps doctors understand that treating hair-pulling disorder requires looking at a person’s overall mental and physical health, not just the hair-pulling behavior itself.

The Quick Take

  • What they studied: How often people with trichotillomania (compulsive hair-pulling) also have other mental health conditions and lifestyle challenges
  • Who participated: 40 people diagnosed with trichotillomania compared to 400 similar people without the condition, matched by age, gender, and ethnicity
  • Key finding: People with hair-pulling disorder were 18 times more likely to have obsessive-compulsive disorder and 10 times more likely to have anxiety disorders
  • What it means for you: If you or someone you know struggles with hair-pulling, it’s important to get comprehensive mental health support, as other conditions are very commonly present

The Research Details

This was a case-control study, which means researchers compared people who have trichotillomania to people who don’t have it. They used a large national health database called ‘All of Us’ to find participants. For every person with hair-pulling disorder, they matched 10 people without it who were similar in age, gender, and ethnicity. This matching helps ensure that any differences they found were likely due to the condition itself, not other factors like age or gender.

This type of study design is good for identifying patterns and connections between different health conditions. By using a national database, researchers could look at real medical records rather than relying on people to remember their health history.

The study used proper statistical methods and controlled for important factors. However, the sample size was relatively small with only 40 people with trichotillomania, which means the results should be confirmed with larger studies.

What the Results Show

The study found extremely strong connections between hair-pulling disorder and several mental health conditions. People with trichotillomania were 18 times more likely to have obsessive-compulsive disorder, 15 times more likely to have borderline personality disorder, and 10 times more likely to have anxiety disorders compared to people without the condition. They were also about 6 times more likely to have alcohol abuse problems and nearly 6 times more likely to have depression. Additionally, they were 4 times more likely to have vitamin D deficiency, which could affect mood and energy levels.

The research also revealed connections to other challenges including chronic fatigue, social anxiety, post-traumatic stress disorder, and ADHD. Interestingly, people with hair-pulling disorder were more likely to report difficulty running errands alone, suggesting the condition may impact daily functioning and independence.

Previous research has shown links between trichotillomania and some mental health conditions, but this study provides a more comprehensive picture of how many different conditions cluster together with hair-pulling behavior.

The main limitation is the small number of people with trichotillomania in the study (only 40), which makes it harder to be completely confident in all the findings. The study also only looked at associations, not whether one condition causes another.

The Bottom Line

If you have trichotillomania, consider getting evaluated for other mental health conditions, especially anxiety, depression, and OCD. A comprehensive treatment approach addressing multiple conditions simultaneously may be more effective than focusing only on hair-pulling behavior.

People with trichotillomania, their families, and healthcare providers should be aware of these connections. This information is most relevant for treatment planning rather than self-diagnosis.

Mental health treatment typically takes months to show significant improvement, and addressing multiple conditions may require patience and ongoing professional support.

Want to Apply This Research?

  • Track daily mood, anxiety levels, and hair-pulling episodes to identify patterns and triggers
  • Monitor vitamin D levels and consider supplementation if deficient, while tracking how this affects mood and hair-pulling urges
  • Long-term tracking of multiple symptoms (mood, anxiety, compulsive behaviors) can help identify which treatments are most effective for your specific combination of conditions
