July 2026 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that hair regrowth differed by position on mouse dorsal skin, appearing earlier at cranial sites compared to caudal sites, and revealed distinct gene expression profiles between these regions, impacting the design and interpretation of hair-regeneration experiments.
April 2025 in “International Journal of Dermatology and Venereology” This study found a significant causal relationship between androgenetic alopecia and schizophrenia, but no causal association between schizophrenia and androgenetic alopecia.
January 2008 in “Journal of Clinical Dermatology” This study found that integrin alpha-6 and p63 may play a role in hair loss, with variable expression patterns in different types of alopecia observed in scalp biopsy samples.
December 2021 in “Medicina estética” This literature review reported limited and low-quality studies on Serenoa repens for androgenetic alopecia, suggesting it may be effective but less so than finasteride, and highlighted the need for better-designed research to confirm its utility.
June 2026 in “Journal of Cutaneous and Aesthetic Surgery” This review proposes an anatomy-based framework for understanding recipient site scalp necrosis in hair transplantation, emphasizing regional vascular vulnerability and surgical factors, but does not provide new clinical results.
