Nearly one billion people worldwide have low levels of Vitamin D in their blood. That’s the reason many young women and men are suffering from Vitamin D deficiency hair loss.

Why is vitamin D important for your body and hair?

Vitamin D is one of the most essential nutrients that your body needs for functioning properly. You can intake this vitamin from some foods but the major source of this vitamin is cholesterol in your body that’s turned into vitamin D when you expose your skin to sunlight. Here are some reasons why you need to think about this vitamin.

Vitamin D and Hair Loss

Vitamin D deficiency is closely connected with hair loss, especially in women. Studies have indicated that many Americans are suffering from this deficiency, which is also the primary reason for hair loss in many of those individuals.

Most cells in our body have a receptor called VDR. This receptor is responsible for turning cholesterol to vitamin D when skin is exposed to sunlight. Scientists have conducted studies to demonstrate that lack of these receptors can cause serious hair loss.

Vitamin D deficiency hair loss is just a warning sign. You could be at the risk of other major problems such as heart disease, high blood pressure, diabetes, and depression. These are just a few consequences of deficiency of this essential vitamin. People not having enough vitamin D in their blood are more prone to gum disease, depression, and influenza.

Apart from the deficiency of vitamin D, hair loss could also be due to lack of copper, zinc, and amino acids in the body. But if you are eating a balanced diet, you may not have to worry about these nutrients as your diet will contain plenty of them.

What are the common risk factors for vitamin D deficiency?

When you expose your body to sunlight, special receptors in your body cells make vitamin D. You could be at a higher risk of suffering from the deficiency of this essential vitamin and suffer from consequential vitamin D deficiency hair loss if you can tick one or more of the following factors.

What is the recommended daily intake of vitamin D?

You should intake 400-800 IU of this essential vitamin D every day for optimal health. If you can consume more, that’s even better as nearly 42% of adults are already suffering from vitamin D deficiency in the US alone.


Whether suffering from vitamin D deficiency hair loss or not, you may want to make some lifestyle and diet changes in your life. When your body makes a lot of vitamin D, you will stay active, have less depression, and your bones and hair will become stronger.
