The hair is made up of a protein called keratin. The keratin part of your hair is dead. However, the follicles are alive. The bottom part of the follicle, the bulb, has the fastest-growing cells in your body.

In the end, vitamin B12 helps the blood cells and makes this process healthier. Due to B12 deficiency, your body tries to handle too many problems at once. This causes high-stress levels, and yes, stress causes hair loss too.

Whatever the reason is, if you start to notice bald spots on your hair out of nowhere, it is best to consult a doctor right away. After a detailed consultation, your doctor may give you prescription medications or may offer changes in your diet. In case of permanent hair loss, you may consider other solutions such as a hair transplant procedure.

Your doctor can also give you a blood test to check your B12 level and help you decide if a supplement is right for you. There are many different types of hair loss and only a medical professional can determine the exact cause.

  • It allows nerves to function correctly and is an important co-factor in myelin formation which protects the nerves.

What Vitamin Deficiency Causes Hair Loss

âIron Deficiency in pre-menopausal women is one the main causes ofhair loss and could indicate an underlying medical condition,â Abraham Armani, MD, a hair restoration surgeon and hair loss expert in Dallas, Texas, tells WebMD Connect to Care.

Iron contributes to hemoglobin production, which helps deliver nutrients and oxygen to hair follicles. Without enough iron, the hair wonât grow, causing progressively thinner hair. Women with heavy periods may also develop iron deficiency anemia. Some other potential causes of iron deficiency include:

  • Not eating enough iron-rich foods, such as red meat, seafood, and beans
  • Blood loss from ulcers

So Why Is A Deficiency In Vitamin B12 Sometimes Associated With Hair Loss

Is Your Hair Loss Caused By Vitamin D, B12 or Iron Deficiency?

The vitamin B complex contains eight different kinds of water-soluble vitamin substances, all of which aid in cell metabolism. These eight vitamin substances include thiamine , riboflavin , niacin , pantothenic acid , vitamin B6, biotin , folate , and vitamin B12.

Of those eight, only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss, but there have only been a few studies, and of those, they do not always prove this connection to be true.

For example, one study saw no significant difference in serum folate levels of patients with diffuse hair loss as compared to controls.

Similarly, Vitamin B12, like folate, plays a role in nucleic acid production which may stimulate hair follicle growth. However, in a study evaluating subjects with Vitamin B12 deficiency, it was found that the reduction in vitamin B12 levels had no adverse effects on hair shedding or hair growth.

While no significant link has been found between many of the Vitamin B substances and hair loss/growth, Biotin is a bit different. While biotin deficiency is rare, it may in fact cause alopecia. However, no large-scale clinical trials have proven that taking biotin supplements will help hair grow back.

Why Is Vitamin B12 Important For Hair

The body needs vitamin B to make red blood cells, DNA, and nerves and to perform other functions. For example, an adult needs 2.4 µg, and if the body cannot get it from food, it must be taken from supplements.

Vitamin B12 is needed to form red blood cells that carry oxygen and other nutrients and distribute them throughout the body. If there is an insufficient number of RBCs, then your hair follicles will suffer from nutrient deprivation.

Vitamin B12 has a big role to play in the production of nucleic acids, which means it also has a role to play in hair follicle health.

A sufficient amount of RBCs is needed to enhance your bodys natural functions, including hair growth. Vitamin B12 helps make your hair follicles healthier and more robust, resulting in better hair growth and stronger strands. Some studies reveal that a vitamin B12 deficiency hampers hair growth.

If you are experiencing hair loss, then try to resolve your vitamin B12 deficiency by taking 3 µg or more of B12 supplement per day to see tangible results in hair growth.

Vitamin B12 Deficiency Anaemia

Lack of Vitamin B12 is known as Vitamin B12 deficiency anaemia. This condition causes your body to produce fewer red blood cells, which are also larger than normal. These are unable to transport enough oxygen to your tissues. How does this affect your hair? When your body is short of oxygen, it channels its available supply to your vital organs to keep them alive, rather than to your hair follicles. Without oxygen, your hair follicles cease to function properly, and your hair may fall out.

Vitamin B12 deficiency can occur if you have a condition called pernicious anaemia, when your body is unable to absorb B12 through the foods you eat. It can also happen if your diet lacks foods rich in Vitamin B12, or if you are taking certain medications that block its absorption. Some contraceptive pills can also cause Vitamin B12 levels to become low.

Symptoms of Vitamin B12 deficiency include :

  • Extreme tiredness
  • Diffuse hair loss from the scalp
  • Premature greying of the hair

Aside from vegetarians, people at risk for a deficiency include those with pernicious anemia, people who have had intestinal surgery such as gastric bypass, those with Crohns or celiac disease, and anyone whose stomach does not produce enough hydrochloric acid to absorb the vitamin B12 thats naturally present in food.

The Connection Between Vitamin B12 And Hair Loss

Vit B12 Deficiency And Hair Loss / Deficiency Symptoms Of Vitamin B12 ...

B12 is responsible for creating and delivering oxygen-rich red blood cells to hair follicles, which keeps hair happy and healthy.

When your B12 levels are too low, and hair loss begins, itâs possible that your hair follicles arenât receiving adequate amounts of oxygen-rich blood, hindering their strength and their growth cycle.
