April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study reported that in mouse models, deletion of EGFR resulted in stem cell hyper-proliferation followed by apoptosis, leading to scarring alopecia, and implicated EGFR's role in maintaining hair follicle quiescence and immune privilege during inflammation.

June 2013 in “The Journal of Pathology” This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that mitochondrial dysfunction might contribute to the pathogenesis of Lichen planopilaris by triggering a metabolic shift that leads to chronic inflammation and hair follicle damage.

August 2022 in “Медицинский совет” This study reported that among patients aged 19 to 60 who experienced hair loss after COVID-19, a treatment involving a complex drug and peptide lotion led to hair improvement in 92% of cases, with good tolerability and no reported side effects.
January 2024 in “Elsevier eBooks” The authors concluded that increasing regulatory T cells in patients with alopecia areata may improve hair follicle regeneration by reducing autoimmune responses, suggesting a potential new therapeutic approach since current treatments are often ineffective with high relapse rates.
