    TLDR Low vitamin D levels are linked to severe and active alopecia areata.
    The study "Trichoscopy pattern and evaluation of serum vitamin D status in alopecia areata" conducted from June 2021 to October 2022, included 59 patients with alopecia areata (AA), a non-scarring hair loss condition. The study aimed to evaluate trichoscopic patterns and severity in individuals with various clinical categories of AA while considering vitamin D levels (VDL). The results showed that VDL was significantly lower in severe AA and active progressive disease. Trichoscopic features could predict disease activity and VDL in patients with AA. Broken and tapering hairs were more represented in patients with progressive disease, while short vellus hairs were seen more in stable or remitting disease. Furthermore, black dots and broken hairs were more prevalent in AA with deficient VDL.

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      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.
