    TLDR Alopecia areata patients have more Propionibacterium acnes and less Staphylococcus epidermidis on their scalps.
    The study investigated the bacterial communities on the scalps of healthy individuals and those with Alopecia areata (AA). It found a significant increase in Propionibacterium acnes and a decrease in Staphylococcus epidermidis in AA subjects, with no significant changes in Staphylococcus aureus. These findings suggested a distinct microbial shift in the scalp of AA patients, providing a basis for further research into the role of microbial populations in hair disorders.
