The hair grows from the root at the bottom of the follicle under your skin. The blood in your scalp goes to the follicle and supplies oxygen and nutrients to the hair root, which helps your hair grow. As your hair grows,it will push through your skin and pass by an oil gland, it is the oil from this gland that makes your hair shiny and soft. But often times, due to inadequate nourishment and damage our natural hair growth is hindered.
