Baldness or hair loss is commonly considered as problem that arises with the growing age but due to some factors, in some cases, even in young or adolescents this problem is evident. Normal human being in a day sheds 50-100 hairs, if hair fall is more than this number then those people are experiencing hair loss. The hair has three parts, one the part that shows, is called shaft, second is root below the skin and third is a follicle from which root of hair originates. The hair is made up of a type of protein called keratin and the follicle of the hair contains pigment called as melanin which makes the color of hair. When a hair falls off another is produced from the same follicle replacing the fallen hair.
