research Androgenetic alopecia in males: a histopathological and ultrastructural study
Hair loss in males involves inflammation, collagen buildup, and follicle damage, with severity increasing with age and baldness duration.
research Differences in Expression of Specific Biomarkers Distinguish Human Beard from Scalp Dermal Papilla Cells
Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
