Which Vitamin Deficiency Causes Hair Loss?

Vitamin Deficiency Causes Hair Loss

For most people, hair loss is permanent. However, if you notice that your hairline is receding and your hair is brittle, it is possible that you simply have a vitamin deficiency. Here are the most vital nutrients to combat hair loss:


If your body doesn’t have enough iron in the bloodstream, it leads to a condition called anemia. The symptoms of anemia include pale skin, feelings of exhaustion, and easily getting short on breath. An unfortunate side-effect to iron deficiency is that the hair follicles don’t receive enough oxygen from the blood, and they enter a dormant stage. When this happens, it is only a matter of time before they begin to fall out.

Vitamin C

Vitamin C has a vital role in many processes throughout the body, including developing and repairing hair, as well as producing collagen. Collagen is the primary protein that makes skin, blood vessels, ligaments, and cartilage. Without vitamin C, your body is not able to reinforce the structures that support healthy hair growth.

Vitamin B-Complex

These vitamins are essential for a variety of reasons, such as reinforcing healthy cellular structure, regulating brain function, and eliminating free-radicals from the bloodstream. Among the vitamin B-complex is biotin, also known as B7. Biotin supports the visual strands of hair that grow from the follicle by strengthening the keratin structure that creates the hair shaft. It also helps break down food into glucose, which the body uses for energy to produce hair, skin, and nails. Individuals who are losing hair and notice brittle nails may have a vitamin B deficiency.


Zinc is necessary for the immune system to function properly, and it ensures that your body effectively absorbs other nutrients from the foods you eat. Without enough zinc, the thyroid becomes unstable, and this quickly leads to a disturbance in the hair cycle. Hyperthyroidism causes the metabolism to rapidly accelerate, and you may first notice significant weight loss for no reason.
