What Is Vitamin B12?


Vitamin B12 is a water-soluble nutrient involved in metabolism. Also known by the name cobalamin, it is one of the 8 essential vitamins that keep the human body’s blood cells healthy. A key player in the functioning and development of nerve and brain cells, it is recommended for the average adult to consume 2.4 micrograms of vitamin B12 regularly.


Although we can’t produce vitamin B12 naturally, we can surely absorb it. One can get his daily supply of this nutrient through foods like dairy products (milk, cheese, and yogurt), fish, meat, and poultry. Other than the aforementioned benefits, vitamin B12 also contributes to the growth of healthy hair.

How Are Vitamin B12 and Hair Growth Connected?


Human hair is made of a protein called keratin. It works by balancing the epithelial cells that overlap to form hair strands. Dermatologists are of the opinion that even though keratin protein is like a pillar that maintains the structure of hair strands, the substance is dead. This is also the reason why it doesn’t hurt when we trim our hair.


However, hair follicles which are located in the dermal layer of the scalp skin are pretty much alive. They need nutrition and oxygen in order to maintain the color of hair strands, their growth, and their texture. Although we can’t provide nutrition directly, we can supply them through blood.


Since vitamin B12 helps in producing red blood cells, having enough of it in our body can help with the hair growth process. Vitamin B12 reaches hair follicles with the help of bulbs located at the bottom of their surface. The base of bulbs, known as papilla, comprises blood vessels. They connect hair follicles to the human body’s blood supply and store oxygen and vitamin B12, thus, nourishing their health and boosting the growth of thick and shiny strands.


What Are the Symptoms of Vitamin B12 Deficiency Hair Loss?


As we said earlier, vitamin B12 is crucial in producing RBCs (red blood cells) that carry oxygen to their hair follicles. Men and women who are B12 deficient will notice their strands becoming brittle and coarse. Their scalp will produce fewer new hair and more strands will fall out than usual.


Vitamin B12 deficiency can also trigger symptoms of anemia, which is related to low iron levels, hair thinning, and hair fall. Other than these signs, men and women suffering from vitamin B12 hair loss will notice:

 

  • Weakness and fatigue
  • Pale skin
  • Numbness
  • Tingling in the hands
  • Weight loss
  • Irritability

 

Lordhair highly recommends men and women see a doctor if they notice any of the aforementioned symptoms of vitamin B12 deficiency hair loss.

What Are the Causes of Vitamin B12 Hair Loss?


Vitamin B12 deficiency hair loss mostly occurs if an individual consumes a lot of unhealthy foods and ignores foods rich in this nutrient. It also happens when the body is facing problems absorbing and processing these nutrients. But these aren’t the only causes of this type of hair fall.


Vitamin B12 hair loss can also be triggered by the following reasons:


#1 Pernicious anaemia


Pernicious anemia is a rare cause of vitamin B12 deficiency hair loss. It gets triggered when the immune system accidentally attacks cells in the stomach called intrinsic factors. For those who don’t know, these cells are essential for proper red blood cell production and function in the human body. Other than hair loss, men and women suffering from pernicious anemia will also face inflammation in the stomach and small intestines.


#2 Gastric surgeries


According to Healio, vitamin B12 deficiency and hair loss occur in 39.6% of people after a gastric bypass. Gastric acid and enzymes are needed for releasing protein-bound vitamin B12 from undigested food. Intrinsic factor, on the other hand, is required for intestinal consumption of vitamin B12.


Once the portion of the stomach or intestines gets surgically removed, the production of an intrinsic factor comes to halt and the total space available for the absorption of vitamin B12 shrinks. As a result, vitamin B12 deficiency occurs and hair fall takes place.


#3 Intestinal problems


Another known cause of vitamin B12 deficiency hair loss. Although there isn’t much evidence on the connection between intestinal issues and hair loss, some scientists claim that diseases like Crohn's disease and celiac disease affect the entire thickness of the intestinal wall and interfere with the absorption of vitamin B12.

What are Treatments for Vitamin B12 Deficiency Hair Loss?


The good news is that hair loss caused by Vitamin B12 is temporary! It can be reversed simply by addressing the deficiency of vitamin B12 in the body. There are some treatments that can help men and women confront this type of hair loss and stop it from getting worse.


Here are some of those:


#1 Vitamin B12 rich diet


The first and foremost thing to do to prevent hair fall is to switch to a healthy diet rich in vitamin B12. Switch to a healthy diet to provide hair follicles with adequate amounts of nutrients including vitamin B12 and restore blood supply and oxygen levels.


Men and women can acquire vitamin B12 naturally from these foods:

 

  • Soya products (miso and tempeh)
  • Meats
  • Boiled eggs
  • Dairy products (cold milk and cheddar cheese)
  • Fortified breakfast cereal
  • Fish (canned tuna, rainbow trout, and haddock)
  • Clams
  • Nutritional fortified yeast

 

#2 Cyanocobalamin


Our readers will be surprised to know that vitamin B12 can also be consumed in the form of tablets. Yes, you read it right! Cyanocobalamin is synthetic vitamin B12 used to prevent and treat deficiency of this nutrient. This restores the levels of RBCs in the body and helps the hair grow normally again.


Available in the form of tablets and liquid, cyanocobalamin can either be swallowed once a day with water or taken with the help of a syringe and needle. We highly suggest getting a prescription from a dermatologist before using this medication for B12 deficiency hair loss as it has its share of side effects.


However, here are known side effects of using cyanocobalamin:

 

  • Stomach pain
  • Bleeding from gums and nose
  • Blue lips and fingernails
  • Chest pain
  • Decreased urine output
  • Fast and heavy breathing
  • Cough

#3 Hair replacement systems


While not really used for minimal B12 hair loss, a lot of men and women nowadays are choosing hair systems to overcome extreme hair loss.
