Trichotillomania Triggered by Vitamin D Deficiency and Resolving Dramatically With Vitamin D Therapy

In 2019, a case study reported a 4-year-old girl with trichotillomania (TTM), a condition where individuals compulsively pull out their hair, which was triggered by a vitamin D deficiency. The study suggested that the girl's TTM symptoms resolved dramatically after she received vitamin D therapy. This case highlighted a potential link between vitamin D deficiency and TTM, suggesting that vitamin D supplementation could be a beneficial treatment for some individuals with TTM. The study emphasized the complex interplay of genetic, psychological, and social factors in TTM, and the need for further research into the neurobiological basis of the disorder.
