Does B12 Deficiency Cause Hair Loss?

Yes, vitamin B12 deficiency can potentially cause hair loss. Vitamin B12 is a vital nutrient for various bodily functions, including the production of red blood cells and the maintenance of healthy nerve cells. It also plays a role in the growth and health of hair.

Hair follicles require an adequate supply of nutrients, including B vitamins like B12, to support healthy hair growth. When the body lacks sufficient vitamin B12, it can lead to a condition called telogen effluvium, which is a form of temporary hair loss. In telogen effluvium, a large number of hair follicles enter the resting phase (telogen) prematurely, leading to excessive hair shedding.

In addition to hair loss, vitamin B12 deficiency can cause other symptoms, such as fatigue, weakness, tingling or numbness in the extremities, and difficulty maintaining balance.

Vitamin B12 deficiency is more common in people who follow strict vegan diets, as B12 is primarily found in animal-based foods. It can also occur in individuals with certain medical conditions that affect nutrient absorption in the gastrointestinal tract, such as pernicious anemia or gastrointestinal disorders.

If you are experiencing hair loss or any concerning symptoms, it’s essential to consult with a healthcare professional. They can perform tests to determine if you have a vitamin B12 deficiency or any other underlying health issues and recommend appropriate treatment and dietary adjustments if necessary.
