How and why does our hair grow...?

Answer» EXPLANATION:Hair grows from the follicle, or root, UNDERNEATH the SKIN. The hair is 'fed' by BLOOD vessels at the base of the follicle, which give it the nourishment it needs to grow. Between starting to grow and falling out years later, each hair passes through four stages: anagen, catagen, telogen and EXOGEN.
