    Area of Science:

    • Dermatology
    • Psychiatry

    Background:

    • Trichotillomania is a hair-pulling disorder often underestimated in prevalence, particularly among children.
    • It can manifest as a cosmetic issue or indicate underlying psychiatric conditions.

    Observation:

    • The Mayo Clinic observed 145 patients over ten years (1968-1977), with 15-20 new cases annually since.
    • Clinical presentation can mimic various alopecias, notably alopecia areata.

    Findings:

    • Scalp biopsy is a valuable diagnostic tool, revealing characteristic findings like catagen hairs, melanin casts, and follicular tears.
    • Associated rare disorders include trichophagy and trichobezoars.

    Implications:

    • A straightforward, empathetic approach may resolve mild cases.
  • Psychiatric consultation is recommended for persistent trichotillomania or suspected comorbid psychiatric disorders.
  • Intensive psychotherapy can benefit selected individuals.
