A circular bald spot can be either. The wrong fork wastes a year of minoxidil for a pulling disorder, or shames an autoimmune patient for “nervous habits.”
The American Academy of Dermatology describes alopecia areata as non-scarring patches, exclamation-mark hairs, and sometimes nail pitting; severe forms include totalis and universalis. Trichotillomania (hair-pulling disorder) is classified among body-focused repetitive behaviours; hairs are broken at different lengths, and there may be a bizarre pattern the patient can map to a hand. Dermatology and psychiatry often share these patients. JAK inhibitors for severe areata are a prescription, labelled conversation — not a forum. This is not a diagnosis and not medical advice.
Do not accuse a child of pulling without a gentle exam. Do not start finasteride for circular patches. Minoxidil is sometimes used as an adjunct in areata under a clinician; it is not a pulling cure. Cognitive-behavioural approaches and habit-reversal are the pulling literature’s core, not a 5-ARI.
Rapid whole-scalp loss, eyebrow-and-lash loss, or suicidal distress is urgent appropriate care. This is not medical advice.

Preguntas frecuentes
Will a biopsy always tell them apart?
Often the exam is enough. Biopsy is a dermatologist tool when the story is mixed. Do not demand one from a screenshot.
Is pulling just anxiety?
It is a diagnosable behaviour disorder with treatment paths. Shame is not therapy. Areata is not “stress baldness” as a moral story either.
Can they coexist?
Yes. Pulling can happen at areata edges. That is why the clinician looks at the whole history.
Do hair fibers help both?
Camouflage can help appearance. It treats neither autoimmune attack nor pulling.
