What is hair made up of and how does it contribute to the overall health and appearance of our hair?

Hair is made up of a protein called keratin, which is produced in hair follicles in the skin. The health and appearance of our hair is influenced by factors such as diet, genetics, and overall health. Proper nutrition and hydration are important for maintaining healthy hair, as well as using gentle hair care products and avoiding excessive heat styling or chemical treatments. Regular trimming and protecting hair from environmental damage can also contribute to the overall health and appearance of our hair.
