Calcipotriol, a vitamin D analog, has been reported to be topically used in treating alopecia areata with promising results. Combination therapy of vitamin D analogs with corticosteroids might also be used in treating alopecia areata.
According to Levitan, getting between 800 and 2,000 IU—or 20 to 50 micrograms—of vitamin D daily is usually enough, and “too much can cause toxicity.” Some people require 5,000 IU daily to maintain optimum blood levels and Vitamin D should be taken in the morning with Magnesium for maximum bioavailability.
Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels. Vitamin D should be supplemented if levels are low.
“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.
Will hair grow back after vitamin D deficiency? The good news is that hair loss due to vitamin D deficiency is usually reversible. Once levels of vitamin D are increased, hair follicles will typically begin to function properly again and hair will start to regrow.
How Long Does It Take for Vitamin D to Work? If you have a vitamin D deficiency, you may notice improvements within 4-6 weeks of consistent supplementation. However, that timeframe can vary depending on what your baseline vitamin D levels are.
Vitamin D and its receptor are intimately involved in hair growth. A deficiency in this nutrient can lead to hair loss (Journal of Cosmetic Dermatology, Nov. 2021). We could, however, find no research on the effects of excess vitamin D on hair loss.
Vitamin D3 supplements are thought to raise vitamin D levels in the bloodstream in around 24 hours. However, it takes up to 7 days for this to be converted into the active form of vitamin D – which is what a blood test will pick up.
Prescription-strength corticosteroids in liquid form can be applied directly to the scalp. This is often an effective treatment for children affected by alopecia areata. Corticosteroid injections into areas of patchy hair loss on the scalp may help revive hair growth within several weeks in people with alopecia areata.
Topical minoxidil
Minoxidil, commonly known as Rogaine, is a topical treatment that's easy to apply and can be easily purchased over the counter. Minoxidil works to help the hair grow faster once the follicle is no longer under attack by the immune system and is capable of producing hair.
Can Alopecia Be Reversed? Whether your hair loss is caused by hormones or an autoimmune disorder, regrowing your hair by using new medications and modifying your diet can be possible as long as you start treatment early.
Causes of Alopecia Areata
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
In most people, new hair eventually grows back in the affected areas, although this process can take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime.
Research published in the journal Annals of Dermatology has also found that zinc levels tend to lower in people with alopecia areata and telogen effluvium -- two common forms of hair loss. Several studies have also found that zinc supplementation may promote healthy hair growth for people with alopecia areata.
In fact, biotin is primarily used for alopecia — a condition that causes hair loss in all sexes. “Biotin helps maintain hair growth and helps with inflammation,” Dr. Bergfeld says. “The hair follicle, the skin and the nails all benefit.”
Ways to Stop Alopecia Areata from Spreading or Worsening
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
We recommend taking it with a source of quality fat in the morning or when you break your fast. Avoid taking vitamin D in the evening (we'll talk about why below). Since vitamin D is a fat-soluble vitamin—meaning it doesn't dissolve in water—your body can most easily absorb it when you take it with food.
Official answer. Generally, it takes a few weeks of taking daily vitamin D supplements for vitamin D levels in the body to rise. Each 1,000 IU of vitamin D3 taken daily is expected to raise blood levels of 25(OD)D by 10 ng/ml after a few weeks.
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.
Symptoms when vitamin D is low
Fatigue. Not sleeping well. Bone pain or achiness. Depression or feelings of sadness.
In general, the two main causes of vitamin D deficiency are: Not getting enough vitamin D in your diet and/or through sunlight. Your body isn't properly absorbing or using vitamin D.
Oranges are one of the fruits rich in Vitamin D as its juice is fortified with calcium & vitamin D. This is one of the best sources of vitamin D for people who are lactose intolerant and cannot include milk & dairy products in their diet.
The most common vitamin D hair growth product is Calcipotriol, which is a prescription topical medication that can help improve scalp condition and alopecia disorders. Oral supplements – Patients could also take vitamin D in capsules or tablets form.
