Premature Graying
|
Graying (Canities) is usually a part of the ageing process. However, the greying of hair before the age of 35 years is considered as Premature Graying. |
|
| Graying happens because of reduction in color pigments known as Melanin. Usually the dilution of pigments is Hereditary. |  |
| A cell present in the hair follicle, known as "Melanocyte" produces a pigment known as "Melanin", which colour the hair shaft. Absence of melanin is considered to be the cause of graying of hair. | |
