This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

Hair proteins change location and structure as hair cells mature.

This study found that fibroblast growth factor 5 may enhance Cashmere goat hair growth by altering the expression of specific genes related to keratin and keratin-associated proteins.

This study reported that three months of platelet-rich plasma injections improved hair counts, thickness, root strength, and overall alopecia in patients with androgenic alopecia, with no major adverse effects.

The compound (NH4)2Mn0.17Cu0.83Cl4.2H₂O has a specific structure, shows weak magnetism at low temperatures, and undergoes phase changes at high temperatures.

This study observed an association between intense itching in anterior chest keloids and an increased density of nerve fibers in the epidermis, alongside elevated expression of the pruritus mediator substance P, though no difference was found in Langerhans cells related to pruritus, location, or region.

Certain genetic differences may affect how likely someone is to get COVID-19 and how severe it might be.

This study explored how long non-coding RNA mediates the effects of FGF5 on the hair follicle development and villus growth of Liaoning cashmere goats.
