Trichotillomania (also called hair-pulling disorder) is a condition where a person repeatedly pulls out hair—often without fully realizing it. It can cause patchy hair loss with broken hairs of different lengths. Many people feel embarrassment or stress about it, but it’s common, treatable, and not a personal failure.

What is trichotillomania?
Trichotillomania is a condition where hair is pulled out repeatedly, leading to visible thinning or bald patches. On our site, it sits under: Non-Scarring Alopecia (Overview) and the main map: Types of Hair Loss.
What it looks like
- Irregular patchy hair loss (often not perfectly round)
- Broken hairs of different lengths within the patch
- Sometimes more noticeable on one side (hand dominance)
- May involve scalp, eyebrows, eyelashes, or beard
Why it happens
Hair pulling can be triggered by stress, boredom, anxiety, or can happen automatically while reading, studying, or watching TV. Many people describe an urge or tension before pulling and relief afterward, but patterns vary.
Conditions that look similar
Trichotillomania is commonly confused with other causes of patchy loss. These quick clues help:
- Smooth round patches with little/no scale → often suggests alopecia areata.
- Scale + broken hairs/“black dots”, especially in children → consider tinea capitis (contagious; needs treatment).
- Edge/hairline thinning from tight styles → see traction alopecia.
- Diffuse shedding after stress/illness → see telogen effluvium.

How it’s diagnosed
Diagnosis is usually based on pattern and scalp exam. A clinician may look for broken hairs of varying lengths and ask about habits, stress, and triggers. If infection is possible (scale, child, contagious contact), they may evaluate for fungal causes.
Treatment options that help
Treatment often focuses on reducing pulling and supporting regrowth. Many people benefit from behavioral approaches (especially habit-focused therapy). If anxiety, depression, or severe distress is present, professional support can make a big difference.
For general hair-loss treatment context and expectations, see:
When to see a doctor
- Patchy loss in a child (rule out tinea capitis)
- Scale, pain, pus, crusting or inflamed scalp
- Rapid worsening or widespread loss
- Significant distress, anxiety, or inability to stop pulling
