Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Hormones and genetics affect hair growth and patterns, with some changes reversible and others not.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

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

Some drugs can cause hair loss, and stopping these drugs often leads to hair regrowth.
