When to worry about bald patches with hair pulling disorder

Bald Patches is a common presentation of Hair Pulling Disorder. Repeated pulling can leave irregular patches with hairs of different lengths, short stubble, broken hairs, or areas that are difficult to examine because of cosmetic coverage. The urge may rise during stress, boredom, concentration, or while touching a particular texture. Some people also bite or swallow pulled hairs, which should be disclosed without shame. Other causes of patchy loss can coexist, so a scalp examination is worthwhile when the pattern changes or does not fit the pulling history.

Book an appointment with a clinician who can check the scalp and help distinguish pulling-related damage from inflammation, infection, or another hair disorder. Keep nails short, cover or protect the area if that reduces automatic pulling, and notice the situations, sensations, and emotions that come just before the urge. Evidence-based behavioural support can teach competing responses and ways to make pulling harder. If hair is being swallowed, say so directly because it changes the health questions your clinician should ask.

Seek prompt care if the scalp is bleeding, repeatedly broken, painful, infected-looking, or producing pus, or if a patch is expanding despite efforts to stop pulling. Arrange earlier support when urges interfere with sleep, study, work, or relationships, or when shame is leading to isolation. Get urgent help if swallowed hair is followed by persistent abdominal pain, vomiting, or difficulty eating. A rapidly changing pattern also deserves review because pulling may not be the only factor.

Ask whether the hair pattern is consistent with pulling, whether the scalp needs treatment for injury, and which behavioural therapy options are available. Discuss practical barriers, such as pulling during sleep or while using a phone, and how to track urges without blaming yourself. Mention hair biting or swallowing, anxiety, low mood, or repetitive habits so the care plan addresses the whole pattern.
