Endocrine controls of primary adult human stem cell biology: Thyroid hormones stimulate keratin 15 expression, apoptosis, and differentiation in human hair follicle epithelial stem cells in situ and in vitro

Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.

Hormones control keratin production in skin and hair.

Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.
