Hair is made of protein called "Keratin". Hair has 2 parts i.e. hair shaft (visible on the scalp) & root (underneath the scalp) which are responsible for the growth of hair. Our hair is attached to scalp at base of the follicle by the hair root. This is the area where hair growth takes place and are continuously nourished by blood vessels providing oxygen and nutrients to the cells. If talking about the thickness of hair, it depends upon the size of hair follicle from which it grows.
There are approximately 100000 – 150000 strands of hair on a person’s scalp. The constant hair growth pace is half inch a month and normally, a person sheds between 50 - 100 hairs every day, as part of the natural hair growth cycle. Also every person has different kind of hair like some have thick hair or thin hair, some have curly hair and these factors also affect the hair growth cycle.
