What Causes Hair Loss

Can A Vitamin D Deficiency Cause Hair Loss?

Vitamin D is an essential vitamin that regulates a variety of bodily functions, including hair growth. There seems to be a link between a deficiency in vitamin D and hair loss. However, some feel that a deficiency in vitamin D is associated with alopecia areata and not androgenic alopecia (genetic hair loss). In this article, we will go over how hair growth correlates with vitamin D, the symptoms of a vitamin D deficiency, and whether a lack of vitamin D can cause male pattern baldness

Vitamin D and Hair Growth 

Vitamin D plays a vital role in creating new hair follicles on the scalp and body and is essential for skin and hair vitality. Hair follicles are living organs, which live in the dermal layer of the skin. Hair follicle hair growth is affected by hormones, neuropeptides, and immune cells- this includes specific vitamins and minerals. 

Vitamin D Deficiency Symptoms

It is difficult for many to pinpoint the symptoms associated with a vitamin D deficiency, and some may never notice any symptoms. However, if you are experiencing any of the following symptoms along with hair loss, it may be wise to check whether you have a deficiency.  

*Delayed Healing

*Muscle Weakness

*Chronic Fatigue

*Low Testosterone

*Mood Changes, including depression and anxiety

These are just a few of the symptoms associated with a lack of vitamin D. There may be an underlying medical condition that is the cause for a vitamin deficiency, which includes Crohn's disease and celiac disease. 

There may be certain medications that could cause a vitamin D deficiency as well. These medications include antifungals, glucocorticoids, anticonvulsants, and certain drugs used to treat HIV. The best way to check for a vitamin deficiency is through a blood test. 

What Are The Treatments 

Luckily, treating a vitamin deficiency is easy, thanks to vitamin supplements. A cheap daily vitamin D supplement can reverse the lack in a short period. A good source of dietary fats is found to be rich in vitamin D, which includes avocado, eggs, cheese, and nuts. Most experts recommend 600IU of vitamin D daily. 


Hereditary hair loss is the most common form of hair loss, which affects nearly 40% of all men by the age of 35. A genetic vulnerability causes genetic hair loss to the hormone called DHT. DHT is the primary catalyst for creating hair loss in both men and women. Vitamin supplements and so-called hair loss growth elixirs may promote healthy hair growth but will do little to nothing to stop DHT from attacking the vulnerable hair follicles. The most effective medication on the market is called Propecia (finasteride)-this medication inhibits the conversion of testosterone into DHT through the bloodstream. Unfortunately, Propecia may cause irreversible sexual side effects, including permanent erectile dysfunction. The only proven method of regrowing hair on a bald scalp is through hair transplant surgery; surgical hair restoration is king.
