Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

This study found that thyroxine modulates peripheral molecular clock gene expression in human hair follicles, which may have implications for treating clock-related diseases in patients with thyroid dysfunction.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

Finasteride potentially treats hair loss by reducing DHT production.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

This study identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.
