“Both vitamin D deficiency, as well as vitamin D excess, may cause hair loss,” Chacon explains. A 2020 study in the International Journal of Dermatology found that vitamin D deficiency may also play a role in the development and severity of androgenetic alopecia, also known as male pattern baldness.
Vitamin D supplements are an excellent way to improve your Vitamin D blood levels. Unfortunately, not many foods naturally contain an adequate amount of Vitamin D. If you are consistent with taking your Vitamin D supplements, there is a likelihood that you will see hair regrowth results within six to eight weeks.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Damage from Vitamin D deficiency is often proportional to the deprived deficiency. Make sure your Vitamin D is normal, not too high or not too low. Keep it within normal limits (30-100). Potentially your hair should grow back within 6-8 months, all other factors being normal.
Vitamin D deficiency is also associated with scarring alopecia. However, conclusive studies to demonstrate the benefit of vitamin D administration in correcting hair loss and managing these conditions are lacking.
But scientific research is scarce on how long it will take for hair to grow back — and if there is a significant amount of hair regrowth — after upping your vitamin D intake and improving your levels. Anecdotal evidence, though, suggests hair may stop shedding and regenerate in as little as two months after treatment.
Although there's no exact timeline on when these supplements can take effect for hair growth, researchers suggest that it can take up to three months to see results. In one study, a female diagnosed with diffuse hair loss caused by low vitamin D serum levels was recommended to take vitamin D supplementation.
Results showed significant improvement in hair growth in young (r=0.457 p<0.003) women and in those, which do not use sunscreen (r=-0.331 p<0.037) but commonly utilize milk or milk protein (r=-0.311 p<0.051). Vitamin D3 therapy resulted in the improvement of the condition in 82.5% (p<0.001) patients of TE.
Possible causes of hair loss include stress, poor diet, and underlying medical conditions. Everyone experiences hair shedding, and it happens to each of us every day. Most people lose 50 to 100 hairs per day as part of this natural cycle, more on days you wash your hair.
The three most common triggers for hair loss in young women are stress, dieting, and hormonal changes. Less commonly, hair loss can be caused by certain autoimmune diseases. Here's more on these four triggers for hair loss in young women.
In other cases, thinning hair is triggered by something going on inside the body — for instance, a thyroid problem, a shift in hormones, a recent pregnancy, or an inflammatory condition. Hair loss may also be genetic. The most common genetic condition is known as female-pattern hair loss, or androgenic alopecia.
There are quite a few differences between vitamin D and vitamin D3, but the main difference between them is that vitamin D is a fat-soluble vitamin that regulates calcium and phosphorous levels in the body, whereas the vitamin D3 is the natural form of vitamin D produced by the body from sunlight.
Vitamin B12
Although a deficiency in B12 may lead to hair loss, research does not suggest that people who do not have a deficiency can improve their hair growth by using a supplement. Nevertheless, getting enough vitamin B12 is essential for overall health.
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
Symptoms when vitamin D is low
Fatigue. Not sleeping well. Bone pain or achiness. Depression or feelings of sadness.
Vitamin D deficiency can lead to a loss of bone density, which can contribute to osteoporosis and fractures (broken bones). Severe vitamin D deficiency can also lead to other diseases. In children, it can cause rickets. Rickets is a rare disease that causes the bones to become soft and bend.
Fatigue. Bone pain. Muscle weakness, muscle aches or muscle cramps. Mood changes, like depression.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
As with male pattern baldness, female pattern baldness comes from hormone imbalances, specifically dihydrotestosterone imbalances, or DHT. This hormone is similar in structure to testosterone, but it is significantly more potent [3]. DHT can attach to receptors on the hair follicles, causing the follicles to shrink.
Some people become anxious about hair loss. Since hair thinning, loss, and balding are common symptoms of stress, including anxiety-caused stress, being anxious about hair loss symptoms can keep the body stressed, causing hair loss symptoms to persist.
