How Do Hair Grow

Hair is made of keratin. Keratin is the protein which is simillar to the protein in our nail. The Composition of hair is 50 percent Carbon, 20 percent Oxygen, 5 percent Sulfur, 20 percent Nitrogen, 5 percent Hydrogen. Someone who’s got an illness or less nutrient may cause their hair to stop growing.

If the illness is very bad and take a long period of times it may cause the hair to fall. If the hair start to grow again it means that the person’s health is getting better. Our body’s health and nutrient is influencing the growth and quality of hair. The change of hormone influence the oil gland in the hair roots.

Oil that produced by the oil gland inside the hair bag protect and covered all of the hair piece. If the production of oil is enermous the hair will be so oilly. But if the oil gland produce a little of oil, the hair will be dull, dry and easy to break.

The dryness of hair can also be cause by how often we paint our hair or used high temperature hair dryer. Human hair is form by folikels and pieces of hair. Folikels is the part that plant in our head skin. Start from the epidermic tissue to dermic. Folikels is a hole inside the skin that surrounded by a group of cell that called papillae.

The cell get its food through the blood that produced hair cell. Hair cell will become hard, die and then turn into new hair. Slowly new hair will be push out and leave the folikels through out the head skin just like a teeth that comes out from its tube. The hair will let go of itself without causing any pain. Each of human head generally have 120.000 folikels.
