An optimal level of Vitamin B12 can prevent hair loss and greying, boost hair growth, and keep your hair moisturised and strong. A sufficient intake of Vitamin B12 nurtures your hair strands and enhances their overall health. Read on to learn more about the Vitamin B12 benefits for hair.

What is Vitamin B12? 

Vitamin B12 is considered to be one of the eight vital B vitamins responsible for the production of Red Blood Cells (RBCs), cellular energy production, and neurological function. Vitamin B12 easily dissolves in water and can remain in your body longer than other water-soluble vitamins. It is also a critical nutrient that provides oxygen to your hair follicles and skin cells. 


Does Vitamin B12 deficiency cause hair loss?

Being deficient in Vitamin B12 can lead to serious hair problems, including excessive hair loss. Due to the absence of RBCs in your body, several functions, such as blood circulation to your hair follicles, slow down. This can ultimately result in scalp dryness and accelerate hair shedding. Here are signs you should look for to identify B12 deficiency in your body: 

Signs and symptoms

  • Anemic body
  • Pale skin
  • Weakness or fatigue
  • Diarrhea
  • Nerve damage 
  • Shortness of breath 
  • Heart palpitations 
  • Loss of appetite
  • Depression
  • Memory loss

Why is Vitamin B12 good for hair? 

Vitamin B12 helps RBCs supply oxygen to your hair strands. Your hair growth can be hampered without an adequate supply of oxygen through tiny blood vessels present in your hair follicles. A low RBC count can eventually lead to partial or complete baldness or faster hair loss. 

 

How does Vitamin B12 work for hair growth? 

  • Reduces hair loss

Vitamin B12 helps prevent hair loss by producing keratin, a protein responsible for strengthening your hair strands. This reduces hair breakage and prevents strands from becoming weak or brittle.   

  • Improves hair texture and shine 

Vitamin B12 nourishes the strands and makes your hair shinier overall. It also enhances the quality and texture of your hair.  

  • Maintains scalp health 

Another known benefit of Vitamin B12 for hair is its role in supporting a healthy scalp by aiding the production of natural oils present in the scalp. 

  • Prevents premature greying 

It moisturises and conditions your hair, thereby reducing the risk of premature greying. 

How to treat Vitamin B12 deficiency for hair loss?

Include sources of Vitamin B12 in your food

  • Animal-based sources like eggs, dairy, meat, shellfish, and oysters 
  • Cereals and plant-based milk 

Make necessary changes in your diet and lifestyle 

  • Limit your alcohol intake 
  • Eat vitamin B12-rich food  
  • Exercise regularly 
  • Practice meditation, yoga or mindfulness to lower stress

Use oral supplements or medications to maintain the level of Vitamin B12

Taking oral supplements daily might be another way to prevent Vitamin B12 deficiency. You can even opt for Vitamin B12 injections to meet the prescribed level of this essential vitamin. Do consult a specialist who can help diagnose the deficiency medically. 

 

Vitamin B12 vs other nutrients for hair health 

Apart from Vitamin B12, there are numerous other nutrients that contribute to your hair health. These include: 

  • Vitamin A
  • Vitamin B
  • Vitamin C
  • Vitamin D
  • Iron
  • Selenium
  • Zinc

A Vitamin B12 deficiency can disrupt your bodily functions and, if left untreated, it can cause serious hair problems like excessive hair shedding. You can address it right away with Traya’s Ultimate Hair Supplements combo, which bridges this gap of nutritional deficiency and maintains an adequate level of Vitamin B12 in your body. It combines the power of Ayurveda and dermatology to address the root causes of hair health.
