What is the role of genetics in hair loss?

ANSWER

Scientists think the gene may affect how sensitive your hair follicles are to a hormone called DHT, which makes them shrink. As they get smaller, the hair that grows back tends to be finer, thinner, and shorter. Eventually, it takes longer for hair to grow back. Then, the follicles will shrink so that no hair grows at all.
