The Link Between Vitamin D Deficiency and Hair Loss

You've probably heard of vitamin D deficiency before. But did you know that this common deficiency can actually lead to hair loss?


Vitamin D plays a vital role in keeping your hair healthy, so when you're deficient in this important nutrient, it's no surprise that your hair may start to suffer. In this blog post, we'll explore the link between vitamin D deficiency and hair loss, as well as what you can do to prevent or treat vitamin D deficiency-related hair loss.


How Does Vitamin D Deficiency Cause Hair Loss?

Vitamin D is essential for healthy hair growth. This important nutrient helps to keep your hair follicles healthy, promotes cell turnover, and prevents the buildup of harmful toxins in your scalp.


When you're deficient in vitamin D, your hair follicles may become weakened and damaged, which can lead to hair loss. In addition, vitamin D helps to maintain a healthy balance of hormones in your body.


A hormonal imbalance is one of the most common causes of hair loss in both men and women, so keeping your levels of vitamin D up is essential for preventing hair loss.


Who Is at Risk for Vitamin D Deficiency-Related Hair Loss?

Although anyone can suffer from vitamin D deficiency-related hair loss, there are certain groups of people who are more at risk than others. If you have dark skin, you may be at greater risk for vitamin D deficiency because darker skin doesn't absorb vitamin D as well as lighter skin.


People who live in northern latitudes may also be at greater risk because they don't get as much exposure to sunlight—one of the best sources of vitamin D.


In addition, people with certain medical conditions like Crohn's disease or celiac disease may be more likely to suffer from vitamin D deficiency because these conditions make it difficult for the body to absorb nutrients from food.


How Can I Prevent or Treat Vitamin D Deficiency-Related Hair Loss?

The best way to prevent or treat vitamin D deficiency-related hair loss is to make sure that you're getting enough vitamin D through diet and supplementation. Foods like fatty fish, eggs, and mushrooms are all good sources of vitamin D.


You can also get your daily dose of vitamin D by spending time outside in the sunshine for about 15 minutes per day. If you don't like the idea of taking supplements, you can also get a topical form of vitamin D that you can apply directly to your scalp. Topical forms of vitamin D are available over the counter at most pharmacies or online.



Vitamin D deficiency is a common problem that can lead to a host of health problems, including hair loss. If you think you may be deficient in this important nutrient, talk to your doctor about ways that you can increase your intake through diet, supplementation, or exposure to sunlight.
