April 2026 in “Frontiers in Medicine” This study found that activating hair follicle resident T cells in a human organ culture can induce an alopecia areata-like immune response, and that the drug farudodstat partially reduced this effect.
In this study, the researchers used a human hair follicle model to demonstrate that T cell stimulation can induce an alopecia areata–like phenotype, with cell proliferation and immune privilege collapse; however, the DHODH inhibitor farudodstat partially mitigated these effects by reducing T cell proliferation.
January 2012 in “Journal of Investigative Dermatology” The document presented various studies on hair and cutaneous development, revealing insights into hair biology and potential therapeutic targets for hair-related conditions. Key findings included the role of stem cells and their niches in hair regeneration, the impact of TACE/ADAM17 depletion on alopecia, and the expression of somatostatin in hair follicles. Research on genetic factors, such as CYLD mutants and P-cadherin, highlighted their importance in hair growth and pigmentation. Studies on hair aging identified genes involved in hair loss in women over 40. Additionally, the potential of keratinocyte precursors from iPS cells for hair follicle regeneration and the effectiveness of a parathyroid hormone analog in reversing chemotherapy-induced alopecia were explored. The document also discussed the role of cholesterol biosynthesis in cicatricial alopecia, the necessity of Wnt signaling for hair follicle initiation, and the effects of ATP-sensitive potassium channel blockers on hair growth. These findings collectively advanced the understanding of hair growth, alopecia treatment, and skin regeneration.
August 2022 in “Nutrients” This ex vivo study found that hair follicles in female pattern hair loss exhibited nutrient insufficiency and dormant metabolism, but maintained nutrient uptake capability, suggesting potential benefits of nutritional supplementation as an adjunct therapy.
June 2025 in “Molecular Therapy — Nucleic Acids” In this study, researchers identified a specific DNA aptamer, Ap.OR2AT4.17, that effectively prolonged hair growth and increased hair shaft elongation in organ-cultured human hair follicles by targeting the olfactory receptor OR2AT4. This finding suggests the aptamer's potential as a novel therapy for hair loss disorders.

,
August 1993 in “Journal of Cutaneous Pathology” In this study, researchers found that as androgenetic alopecia severity increased, the hair follicle matrix and dermal papilla's volume and cell nuclei number decreased, especially in the papilla.
12 citations
,
March 2019 in “Lasers in Surgery and Medicine” This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.
