    TLDR A gluten-free diet stopped a child's hair-eating behavior and suggested she had celiac disease.
    In 2014, a case report described an 8-year-old girl with undiagnosed celiac disease who exhibited non-scarring alopecia, trichotillomania, and trichophagia, resulting in a trichobezoar. Despite her iron deficiency, her hemoglobin levels remained normal. Upon adopting a gluten-free diet, her symptoms of trichotillomania and trichophagia were immediately alleviated. The case indicated that behavioral disorders like trichotillomania could be an initial sign of celiac disease, regardless of nutritional deficiencies. The resolution of her symptoms, including the behavioral issues, upon starting a gluten-free diet confirmed the diagnosis of celiac disease. This case underscores the potential link between celiac disease and behavioral disorders, and suggests that celiac disease should be considered in patients presenting with trichotillomania and trichophagia, even if they do not have anemia.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      A user suggests that deeper microneedling with Verteporfin injections might help regrow hair in areas with scar tissue, alongside a DHT blocker. Another user explains that hair loss might be due to reduced Wnt/β-Catenin signaling and suggests that treatments like Minoxidil, Finasteride, and microneedling could potentially reverse it.
