Trichotillomania is defined as hair loss due to patient’s repetitive self-pulling of hair. At dermatoscopy, the recognition of multiple hairs broken at different lengths and fraying of the extremities (trichoptilosis) are the most consistent features. “Flame hairs” appear as semitransparent, wavy, and cone-shaped hair residues resembling flames. In “coiled hairs,” the remaining distal part of hair shaft may contract and coil. “Hook hairs” are partially coiled hairs. In “tulip hairs,” the distal ends of the hair shafts appear empty inside. The “V-sign” can be found when two hairs emerging from the same follicular unit are pulled simultaneously. The interfollicular area may reveal the presence of hair residue particles, called “hair powders.” Often, red dots corresponding to follicular microhemorrhages may suggest the history of forced pull off.
