Hair follicle stem cells are mainly in the bulge region and can help repair skin and form hair and glands, but more research is needed to fully understand them.

White hair grows thicker and faster than black hair due to higher activity of growth-related genes and proteins.

Aging causes changes in hair follicles, leading to weaker hair growth.

Selecting specific KRTAP26-1 gene variants can improve wool quality in sheep.

The 4C32 gene may help in mouse skin development and differentiation.

KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.

Hair straightening can damage hair and pose health risks, including exposure to carcinogens and hair loss.
