January 2006 in “Hormone Research in Paediatrics” In this case study, a girl with hereditary vitamin D resistant rickets had a novel mutation in the VDR gene that affected hair cycling without causing total alopecia, suggesting ligand-independent VDR function in hair cycling.
August 2026 in “Molecular and Cellular Biochemistry” This study found that administering tolerogenic dendritic cell-conditioned medium to dihydrotestosterone-treated mice promoted hair regrowth by modulating the follicular microenvironment, reducing pro-inflammatory cytokines, and activating key signaling pathways, highlighting its potential as a treatment for androgenetic alopecia.

July 2009 in “Journal of Cell Science” The researchers found that corneodesmosin is crucial for maintaining skin barrier integrity and hair follicle architecture in mice, with its deletion leading to severe skin and hair abnormalities.
December 2021 in “Journal of clinical images and medical case reports” This descriptive study observed that a "moth-eaten" pattern of hair loss can occur in several skin diseases, with lichen planopilaris and discoid lupus erythematosus being among the most common conditions identified in patients from Baghdad, emphasizing its potential as a diagnostic tool for clinicians.

October 1987 in “Journal of Investigative Dermatology” December 2025 in “International Journal of Dermatology” This systematic review reported that while combining low-dose oral minoxidil with Janus kinase inhibitors may enhance treatment outcomes in alopecia areata, the evidence remains weak due to limited sample sizes and potential publication bias, and more rigorous trials are necessary to assess efficacy and safety.
November 2025 in “Nature Communications” This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.
