Is hair dead follicules

Hair itself is made up of a protein called keratin and is considered "dead" once it emerges from the follicle, as it lacks blood supply and nerve endings. However, hair follicles, which are located in the skin, are very much alive and play a crucial role in hair growth. They contain living cells that divide and produce hair, and they are also responsible for the hair's growth cycle. Therefore, while the visible part of the hair is dead, the follicle itself is a vital living structure.
