Let’s Understand How The Deficiency Of Vitamin B12 Can Lead To Hair Loss
Vitamin B12 plays a vital role in cell replication and DNA formation. Though there are other vitamins and minerals that help in these cellular processes, Vitamin B12 is most important. Deficiency of same can cause difficulties in above functions.
A deficiency of Vitamin B12 will slow down the process of genome replication which in turn slows down or stops hair growth. In such case, the natural hair will fall off naturally. Cobalamin is required by hair follicles to replicate them and for effective hair growth.
Vitamin B12 is also required for synthesis of red blood cells. Deficiency of this vitamin means the RBCs will not get oxygen properly. As a result, the hair follicles will suffer because they will not get the necessary nutrients from the blood. Thus, causing the hair to become brittle, stunted growth and eventually fall off.
How Can The Deficiency Of Vitamin B12 Cause Grey Hair?
Melanin, a natural pigment, determines the colour of hair. Melanocytes, the pigment cells near the hair follicles do the duty of injecting melanin into the hair as it grows, giving it colour. This melanocyte activity decreases with age leading to less pigmentation and eventually, grey hair.
As we know, Vitamin B12 is essential to vitalise melanocytes cells for hair pigmentation. Thus, causing grey hairs.
Treatment Of Vitamin B12 Deficiency:
- The best way to treat Vitamin B12 deficiency is to get it through natural sources.
- Foods rich in Vitamin B12 must be consumed regularly.
- Foods rich in these vitamins are liver, other organ meats, shellfish, red meats, poultry, eggs, milk and dairy products.
