Vitamin D Deficiency and Natural Hair

A while back, I wrote a blog post about vitamins and minerals that contribute to healthy hair.  This led me do some research about which nutrients are likely to be deficient in people today.  As you can imagine from the title, a common nutrient deficiency is Vitamin D.  According to the HealthLine website, two years ago around 42% of people in the U.S. were potentially Vitamin D deficient.  This percentage was around 82% for people who are melanin rich because dark skin produces less Vitamin D from sunlight exposure.


What is Vitamin D?

Actually, Vitamin D is not a vitamin but is a prohormone because our skin can produce Vitamin D when it is expose to sunlight.  Vitamin D is not a vitamin because vitamins are dietary factors that cannot be produced by the body.


Hair Benefit from Vitamin D

Hair loss can be a symptom of Vitamin D deficiency.  As some of us may know, scalp stimulation promotes hair growth.  Vitamin D is a nutrient that contributes to the stimulation of new and old hair follicles.  Furthermore, according to the HealthLine website, there have been studies that link Vitamin D deficiency to alopecia.


Other benefits of Vitamin D

There are many benefits to Vitamin D sufficiency.  However, the biggest understanding I’ve gained is Vitamin D helps reduce the risk of various diseases.  Some of these diseases include but are not limited to diabetes, Alzheimer’s, heart diseases, osteoporosis, and even cancer.


Sources of Vitamin D

Fortunately, there are a variety of solutions to prevent Vitamin D deficiency.  A sufficient amount of Vitamin D can be obtained by exposing your bare skin (without sunscreen) to direct sunlight for around 10 minutes a few times a week.  Please consider the risk of sunburn or skin defects when choosing this option.  Also, we can consume foods that are rich in Vitamin D like non-dairy milk.  Another solution is to take Vitamin D supplements.  There’s so much research on which type of supplement to take, so I’ve concluded that adults under the age of 70 should take a Vitamin D3 supplement with around 600IUs.  However, I encourage you to do your own research and consult with your doctor about what’s best for your current circumstances.


I know there are some people out there who have tried every trick and gimmick to get their hair to grow but still have not noticed much growth.  I’m not here to tell those people to give up on their goals; however, it may be time for them to make some lifestyle changes. The appearance of our bodies (i.e. hair, skin, nails) may tell us it’s time to be concerned about what’s happening inside of our bodies.

  1. Great post! I don’t have textured hair, but when I started taking a vitamin D supplement, my baby hairs started sprouting and my hair wasn’t so dry.
