As years pass by the body production of pigment melanin grows to halt causing the new hair that grows to be without pigment or color, meaning grey or white.
Every one of us has genetic trigger when melamine production is stopped, but there are some other factors that can speed up this occurrence. Those other factors may be early menopause, thyroid disorders (diseases like Grave’s, Hashimoto, hyperthyroidism, hypothyroidism), Vitiligo (condition when your skin loses melanocytes, resulting in prematurely grey hair and pale patches on the skin), smoking, vitamin B12 deficiency (disorder called anemia, and it may happen due to a diet without eggs, milk or meat or due to stomach or intestine surgery when part of intestines is removed – stomach absorbs vitamin B12).
