One of the characteristics of all mammals is having hair.πββ Most of the chemical makeup of hair is a protein called keratin.
The location under the skin that allows a hair or strands of hairπ©πΌ to grow is called a follicle. It is found in the skin layer called the dermis.
The only “living” part of a hair is found in the follicle as it grows. The hair strand above the skin has no activity and so is considered “dead”.β
