Trichotillomania (TTM) is a disorder characterized by the individual pulling out his hair in a repetitive manner, resulting in significant hair loss, a feeling of tension before the hair pulling, and pleasure during it. Our understanding of the neurobiological basis of TTM is limited. However, the condition in all likelihood involves multiple pathways and a complex interaction between various genetic, psychological, and social factors. Vitamin D deficiency is thought to be linked to rickets in children and to a range of different diseases in adults, including osteoporosis, osteomalacia, cardiovascular diseases, cancer, dermatological diseases, and psychiatric disorders. We report a case of a 4-year-old girl with TTM triggered by vitamin D deficiency resolving dramatically with vitamin D therapy.
