Can a Vitamin D Deficiency Cause Hair Loss?: How It Happens and How to Fix It

New information is constantly available about how different deficiencies in vitamins and minerals can play a role in negative health effects, even in seemingly unrelated parts of your body. Vitamin D has been touted as one of those all-important vitamins that many people should supplement, since it seems to play a role in so many vital functions of the body, including the healthy formation of bone and helping the body absorb calcium properly. 

A deficiency in this essential vitamin has also been linked to hair loss. Below we will cover just what Vitamin D does for hair, why your levels might be low, how to get Vitamin D levels back to normal, and how to help prevent a deficiency.

What does Vitamin D have to do with hair loss?

Vitamin D isn’t all about bones, it also helps stimulate hair follicles to grow hair. Your hair is on a natural cycle of growth, no growth, and then loss of that hair. Losing 50-100 hairs per day on average is a normal phase of that growth cycle. But, when the next phase of hair growth isn’t stepping in to replace those lost hairs due to a Vitamin D deficiency, slowed growth can make hair seem less thick over time. 

In addition to its role in the growth phase of hair, lower levels of Vitamin D are seen more often in those with the autoimmune disease alopecia areata as compared to matched controls without alopecia. One study looked into the Vitamin D levels in women experiencing female pattern hair loss and compared the levels with women who were not experiencing hair loss and found that women dealing with hair loss had significantly lower levels than women with no hair loss issues.

What causes low Vitamin D levels?

There are three ways that you can get your daily amount of Vitamin D: you can synthesize it from getting some sun, you can consume it in food, or you can supplement it in a capsule or tablet. So, if you are not regularly getting enough Vitamin D from one or a combination of all of these sources, you may end up being deficient. People who don’t spend time out in the sun or who live in darker climates may develop a Vitamin D deficiency if they don’t make an effort to eat or supplement Vitamin D. 

Also, people with a darker complexion do not synthesize Vitamin D from the sun as well as those with paler skin. The same Vitamin D production from sun exposure also declines as you get older. Additionally, Vitamin D levels can decline when the Vitamin D you consume is not able to be absorbed from the GI tract due to a gastrointestinal illness like Chron’s or celiac disease.

How can you tell if you have low Vitamin D levels?

Low Vitamin D levels are not always something that you can feel, and most people who have low Vitamin D levels may feel just fine. However, for some people low levels of Vitamin D may come along with the following symptoms:

  • Mood changes
  • Fractures
  • Decreased bone density
  • Muscle weakness
  • Slow-healing wounds
  • Worsening or new high blood pressure levels
  • Fatigue
  • Chronic pain
  • Reduced endurance

Most doctors routinely check on Vitamin D levels with a blood panel. But, if your doctor has never mentioned Vitamin D levels with you, ask them about checking on the levels during your next appointment.

Vitamin D deficiency treatment

The treatment for Vitamin D deficiency is starting a plan to make sure that you are getting enough Vitamin D every day.

Depending on your levels, this may mean that your doctor recommends an over-the-counter supplement to you, suggest for you to increase your consumption of certain foods, or may even prescribe a high-dose Vitamin D supplement for you to use called Ergocalciferol.

Your doctor will likely then check your blood levels of Vitamin D on a return visit to see how the treatment is going and adjust any recommendations accordingly.
