According to Levitan, consuming between 800 and 2,000 IU or 20 to 50 micrograms of vitamin D a day is usually enough and “too much can cause toxicity. Some people need 5000 IU daily to maintain optimal blood levels and vitamin D should be taken in the morning with Magnesium for maximum bioavailability. Hair growth vitamins, such as vitamin D supplements, are said to help curb alopecia and baldness to a certain extent. Vitamin D deficiency is thought to cause certain types of hair loss problems, namely alopecia areata and male pattern baldness.
Low vitamin D levels can be associated with a poor hair growth cycle, which can lead to slow growth that could aggravate thinning hair and the appearance of bald spots. That said, she says the three most common types of hair loss are telogen effluvium (mentioned above), alopecia areata (also mentioned above), and trichotillomania. Since many things could be at stake, Green says the best way to treat hair loss is to start by finding the underlying problem that is causing it. For example, a study published by the National Center for Biotechnology Information of women between the ages of 18 and 45 found that low levels of vitamin D2 were associated with two common types of hair loss.
While research is somewhat limited, there is evidence that vitamin D deficiency can affect healthy hair growth, leading to loss, thinning, and irregular hair loss affecting certain parts of the scalp. In some cases, if hair loss occurs in small areas, it may be the result of an autoimmune condition called alopecia areata (Spano, 201). In addition to the most common causes of hair loss, Green says that living in a physically toxic environment can also lead to loss. Fortunately, there are several science-backed hair loss treatment options available that can help you slow or stop hair loss.
The results of vitamin D supplements for hair care and hair loss treatment can still vary depending on the severity of a person's hair loss symptoms. Hair loss and thinning problems can also be caused by other vitamin and nutritional deficiencies. Along with vitamin D supplements, these alternatives are only part of a larger list of treatments for hair loss. Vitamin D supplements may work best for hair restoration when taken in conjunction with appropriate treatments for hair loss.
Vitamin D supplements are a good solution for restoring ideal hair health, but they may not be enough for the symptoms of serious hair loss problems. Research has shown that people with vitamin D deficiency often experience some degree of hair loss. In a recent study, it has been suggested to measure the level of vitamin D in patients complaining of hair loss, in addition to tests such as complete blood count (CBC), thyroid-stimulating hormone, ferritin, testosterone and dehydroepiandrosterone sulfate.
