Vitamin b12 for hair

It is not just about having the right genes or using the right cosmetics to have long, thick and shiny hair. It’s all futile if you don’t have adequate levels of hair vitamins, especially vitamin B12. If you know all the facts about the benefits of Vitamin B12 for hair, then you can accept the relevance of a balanced diet.

Vitamin B12 – What is it?

Vitamin B12, commonly known as cobalamin, is a water-soluble vitamin that is essential for DNA synthesis and cell production. This water-soluble vitamin, which belongs to the B complex vitamin family, contributes to the production of red blood cells and promotes healthy central nervous system function in your body. Most water-soluble vitamins cannot normally be stored in large amounts by the body, however, vitamin B12, which is present in the liver, can be stored for more than 4 years.

If you notice abnormal hair loss and there is no replenishment, you may be deficient in Vitamin B12. You should consult your doctor or health expert about the cause of hair loss and if diagnostic tests determine a deficiency, you should either include food sources rich in vitamin B12 or take hair growth supplements. You should start taking Vitamin B12.

How is Vitamin B12 deficiency linked to hair loss ?

B12 for hair is not only important for hair growth, but is also very essential for the brain, nerves and blood cells.

When viewed under a microscope, each strand of your hair looks like a thick tube. This tube-like structure is called the hair shaft. Most of your hair is made of a strong protein called keratin.

Although the protein keratin, the major component of your hair, is dead, the hair follicles beneath it are still very much alive and in need of nutrients. Only blood can deliver the nutrients and oxygen that are needed for hair follicles to grow. Your hair cells grow and increase in number, forming a new hair strand. Blood vessels at the base of your hair bulb connect your body’s blood supply to your hair follicles.

The development of red blood cells that are oxygen-rich and carry oxygen to your hair follicles is aided by vitamin B12. Creating new hair cells and promoting hair growth are biological processes.

Cell division, cellular metabolism, and DNA replication are all greatly influenced by this vitamin. Every time a hair cell divides, it creates a duplicate. Synthesis of DNA for hair growth and absorption of Vitamin B12 are the two main factors that contribute to hair growth.

Does B12 deficiency also cause thinning hair? Yes it can. Red blood cells are produced by cobalamin or vitamin B12 in the bloodstream. Your low red blood cell count may indicate vitamin B12 deficiency anemia. Possible symptoms of a deficiency in this vitamin are hair loss or thinning of the hair.
