Understanding the science behind greying hair

• A pigment called melanin which is present in the hair renders the natural black color to our hair. The production of melanin takes place during the hair growth (anagen) phase in the roots of the hair beneath the scalp.
• The produced melanin is then transported upwards in the hair, thus imparting color to the hair shaft. The color intensity of hair is directly proportional to the melanin content in it.
• As we age, a natural loss of the melanin pigment causes the reduction in intensity of the hair color which eventually leads to loss of hair color i.e greying of hair. This is a natural phenomena but can be impacted due to various reasons mentioned below.
