Why Do We Have Hair?
Composition Of Hair
Hair follicles in the outer layer of the skin produce a protein called keratin that makes up the hair. The part of hair present outside of the skin usually visible to us is a layer of dead keratin. The color of hair is due to the presence of pigmentation called eumelanin. If it is present in large amount hair are usually darker or otherwise, they are lighter in color. The dark hair is usually less thick as compared to colors lighter in color. This is due to the more eumelanin present in darker hair.
Significance Of Hair
Since ancient time when humans had a body covered with dense layers of hair, a time when clothes had no existence to modern humans having scarce hair then their ancestors, hair served a different purpose for them than for us. Caveman used to have dense thick hair which provided protection to their naked bodies from weather conditions and also protected skin from scratches and cuts. It also served as camouflage for them. Today, hair on our head protect us from the sun, our eyelashes serve as the first layer of protection to our eyes against dust, and bugs etc., dry hair on armpits act as a lubricant and avoid the chafing in legs and arms while moving.
Hair is not only dead keratin cells that act as a protection layer. Apart from serving the purpose of protection from sun, dust and other substances hair play a lot of neurological functions too. Our hair respond to any disturbance from the external environment is quickly detected by our hair and is transmitted to our brain in the form of neurological impulses so that required action can be taken. An example of the statement is the detection of malaria-causing mosquito having the painless bite. As the mosquito usually attacks on legs and hair on legs transmits a signal to the brain to act before it comes in contact with the skin.
Hair is an important and integral part of our body. There is a lot of vital function that our hair performs and excessive hair fall may cause a higher risk of deterioration of health. Hair fall is also the main reason for stress as hair on our head when styled dictates our style and personality.
