Every hair is made up of a tough protein called keratin. They come out from tiny holes in the body called hair follicles. Approximately a person is born with 50, 00,000 hair follicles on whole body abbot which 100,000 follicles are found on a human skull. types of hair depend upon the structure of these follicles. People with oval-shaped follicles have curly hair and with round follicles possess straight hair.
Hair growth cycle:
This cycle or stages of growth consists of three phases. Each hair on the body is on its own stage of development when a cycle is completed, it restarts and another strained of hair starts forming. The hair physically grows from 0.5 to 1cm per month. The growth rate varies from person to person it is effected by different e.g. age, genetics, sex, health conditions, ethnicity and numerous environmental factors. Hair tends to grow slowly with the age
Anagen (growth phase):
During this phase hair physically develop. Each hair has a root made of protein. Because of blood circulation root gets nutrients and proteins which cell needs to divide. As they divide they build hair, which pushes up through the skin and can last from 3 to 7 years. The span of this phase is determined by genetics. The longer hair stays in this phase, the longer it will grow. overtime, the length of the anagen stage decreases. and the hair starts becoming thinner and weaker. to ensure a longer anagen period it is, therefore, important to have necessary nutrients in the diet.
Catagen (transition phase):
This is the transitional stage and lasts for about two to three weeks. It actually allows the hair follicles to renew in a sense. The hair follicles shrink and detach from derma lyre, cutting the hair off from its blood supply. Approximately 3%of all hair is in this phase at any given time. In this stage, hair stops growing
Telogen (Resting phase):
Telogen or shedding phase of hair growth lasts for several years approximately 3 to 4 months. Hair follicles remain inactive during this stage.10 to 15 per cent of hair of a human skull remains in this phase at any given time. During this time a new hair starts to develop, pushing the old out.

Hair colour:
Hair colour is an important part of hair growth. The colour of hair is caused by the amount of pigment called melanin. the abundance of melanin causes darker hair. the type and amount of melanin are determined by the genes. Hair colour changes with the passage of time as well as because of malnutrition.
