As we age the hair follicle loses the ability to produce the color pigment and the hair will turn white. Normally the greying of hair (known as Canities) is not a welcome visitor, it signifies we are getting older, but what if this happens when you are still young? In your 20’s and 30’s. If you do not have the genetic background it could be the color pigment is lost because of dietary deficiencies, notably Calcium, Iron and Vitamin B12, indicating pernicious anemia, thyroid or an auto immune response. Now I am not saying everyone with grey hair should self-medicate but It is worthwhile taking a closer look at your nutritional requirements and ensure you are getting enough foods that contains these minerals, which are quite often seen to be deficient in protein restricting diets.
