Why our hair turns Grey
Hair turning grey is the part of the natural aging process which we all undergo in our life. We must have seen our parents and our grandparents having naturally colored hair during their life, but with aging, their hair turns grey. The hair on our head comprises two parts root and shaft. The source of the hair is the bottom part where the hair gets attached to the scalp while the shaft is the part of colored hair that grows on our head. The root is surrounded by the tissue underneath the scalp, which is termed as a follicle. The follicle comprises pigmented cells, which continually lead to the production of melanin within the hair shaft giving it a black, blonde, dark brown, or brown color.
Melanin is the same pigment that is present in our skin, offering its color, and this same pigment is present in our hair, which leads to colored hair. The lighter or darker shade of the hair helps in the identification of the type of hair color a person will have. In our aging process, the pigmented cells present in our scalp start dying, and there are only a few melanin cells present in the follicles due to which the hair strand does not have any pigment melanin leading to transparent color like white, silver or gray. When people continue to grow older, there are only fewer cells within the scalp, which makes your hair turn gray. However, grey hair can occur in people at any time of their life, whether they are young or old. Some people have gray hair during their teenage phase or when they are growing into adults, while others may have their first silver hair during the late ’30s or late ’40s.
