Why Some People Have Curly Hair?

Hair can have many different colours, textures and thicknesses for different people. Some people have straight and silky hair. Some have coarse and thick hair. The rate at which a person’s hair grows is also different from another’s.

Our hair get nourishment from its root where it is attached to our scalp. At the root of the hair there are cells which contain pigment. These cells multiply and go upward with the growing shafts of hair. The cells die, but the pigment granules remain with the hair. The colour of the hair depends on the colour of these pigment granules. If the pigment granules contain black colour the hair will look black. If it has reddish shade the hair will look red.

The horny substance in which the pigment is buried, is yellow. The final colour of the hair is the mixture of these two.

If you cut across a shaft of hair and see it under the microscope, its structure will show a definite shape: round, oval, flat or elliptical. The texture and shape of hair depends largely upon this. Round shaped hair produces straight hair, while the oval ones produce wavy and curly hair. Elliptical or kidney – shaped hair will produce short and curly (also called ‘woolly’) hair.
