The human body is covered in follicles that produce hair. Basically, the hair is a protein filament called keratin growing in the deep dermis. Hair is a defining trait of mammals. As a simple structure, the hair protects the human body from damage. It develops on the epidermis and grows away from it to form a protective layer. The human hair has a number of uses:
Provides protection against the sun’s UV rays and debris – the harmful rays are diffused due to the natural snags in the human hair while the good ones pass through; the hair also acts as a deflection mechanism against external debris.
For the detection of harmful substances such as heavy harmful metals (arsenic, lead, mercury etc.)
Defends the body against excessive heat by keeping the head cool.
According to anthropologists, humans had a protective coating of hair all over their body to regulate body temperatures. As primates on all fours, the entire body was exposed to UV rays and hence the covering. With our gradual evolution to the standing, position hair was not required everywhere and that’s when we began losing it. Even modern humans maintain the same number of hair follicles as apes.
There are three phases to hair growth:
Anagen Phase: Also known as the growth phase, the hair spends between 2-6 years in this active stage; the growth rate of hair is approx. 1.25 cm every 28 days.
Catagen Phase: In this transitional phase hair growth slows down and the hair follicle shrinks; 3% of hairs are always in this stage and typically this lasts for 10 days.
Telogen Phase: The growth of hair stops in the telogen or resting phase which lasts 3 months. The old hair is pushed out and detaches itself from the hair follicle new hair begins to grow.
The average growth rate of the hair is about 0.3 to 0.4 mm per day though growth rate differs from individual to individual. Melanin produced in the hair follicle is the pigment responsible for the colour of the hair. Hair turns grey as we grow older because the pigment cells die. One of the most interesting facts about hair is that the human foetus develops all of its follicles (about 5 million of them) by week 22 in the womb. We do not generate any new follicles during the rest of our lifetime!

If you think hair thinning and baldness only affected the older generation, then you are in for a surprise. Male pattern baldness is the cause of 95% of hair loss in men and female pattern loss has a similar statistic. The psychologically painful process can begin in the late teens for the unlucky ones.
