Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Follicular Unit Extraction (FUE) is a less invasive hair transplant method with minimal scarring, suitable for about 60% of patients, especially those needing fewer grafts and quicker recovery.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Prolactin affects hair growth cycles and can cause early hair follicle regression.
