Exploring the Link Between Hair, Hormones and Nutrition
Have you been catching more glimpses of your scalp lately? Noticing your hairline creeping back a little more each year? If so, you’re not alone. Hair changes are common for many men, especially as they get older. But that doesn’t mean you shouldn’t be curious about what’s behind it, including the possible link between vitamin D and hair loss, or what role nutrition might play.
Let’s talk about a not-so-obvious player in hair and hormone health: vitamin D. Your sunshine vitamin might be doing more than just supporting bones and immunity. It may also have something to say when it comes to male pattern baldness.
What Is Male Pattern Baldness?
Male pattern baldness, also called androgenetic alopecia, is the most common type of hair loss in men. It usually begins with thinning at the temples or crown and progresses gradually.
While genetics are a major factor, hormones also play a key role. A specific hormone called dihydrotestosterone (DHT) is made from testosterone. In some men, DHT shrinks the hair follicles, making it harder for hair to grow.
But hormones aren’t the whole story. Nutrition, including your vitamin D status, may influence how your hair follicles behave, and growing research is exploring the connection between vitamin D and hair loss. That’s where things get interesting.
Vitamin D Is Not Just for Bones
Vitamin D is a fat-soluble vitamin your body produces when your skin is exposed to sunlight. You can also get it from food and supplements.
Why should you care about it for your hair?
Because vitamin D helps:
Hair follicles have vitamin D receptors. When your levels are low, those receptors may not function well, and that can slow or disrupt the hair growth cycle.
Can Vitamin D Prevent Hair Loss?
Not completely. Male pattern baldness is mostly driven by genetics and hormones like DHT. But if you’re low in vitamin D, getting enough may help:
Vitamin D is not a cure, but it may be a valuable part of your overall hair and hormone health strategy.
Signs You Might Be Low in Vitamin D
You may be low in vitamin D if you:
A simple blood test can check your vitamin D level. If it’s low, a healthcare provider such as your doctor or registered dietitian can help you correct it safely.
How to Get More Vitamin D
Follow Health Canada’s Guidance:
Health Canada recommends that adults get 600 to 800 IU of vitamin D daily, which can be achieved through a combination of sunlight and food.
In the summer, 10 to 15 minutes of daily sun exposure to the arms and legs may be enough for some individuals. In the winter, or if you have limited sun exposure, diet and supplementation may be more important.
Eat vitamin D-rich foods
Include foods such as:
Consider a supplement if needed
If your diet and sun exposure are not enough, a registered dietitian or your healthcare provider may suggest a vitamin D supplement. Most Canadians benefit from a supplement providing 600 to 1,000 IU daily.
For best absorption, take it with a meal containing healthy fat such as olive oil, avocado or nuts.
Final Thoughts
Male pattern baldness is common, and for many men, it is a natural part of aging. But that doesn’t mean your hair and hormone health should be ignored.
While vitamin D will not reverse hair loss caused by DHT or genetics, it plays a valuable role in supporting the scalp, hair follicles and hormonal balance. Making sure you are not deficient is one simple and proactive step you can take.
