    TLDR Alopecia areata patients have more Propionibacterium acnes and less Staphylococcus epidermidis on their scalps.
    The study "Scalp bacterial shift in Alopecia areata" found significant differences in the scalp microbiome between Alopecia areata (AA) patients and healthy controls. Specifically, AA patients had an increased abundance of Propionibacterium acnes and a decreased abundance of Staphylococcus epidermidis, while Staphylococcus aureus levels remained unchanged. The study, which included 15 AA patients and 15 healthy individuals, suggested that these microbial shifts could play a role in the pathogenesis of AA, potentially offering new avenues for treatment. The findings highlighted the need for further research into the role of microbial communities in hair disorders.

      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.
