It certainly helps to thicken existing hair, Levitan says. When it comes to hair growth, vitamin D is known to work by binding to certain receptors found in the hair follicle. They help regulate their function by stimulating cellular activity, particularly in the anagen phase of the hair growth cycle. Sufficient levels of vitamin D can help create new hair follicles to support healthy hair growth, while conversely, vitamin D deficiency can disrupt the hair follicle cycle and cause poor hair growth.
So when does hair grow back after taking vitamin D supplements? The effects of vitamin D supplements for hair growth may be different for everyone, depending on how low their vitamin levels are. It may take 3 to 4 months to increase the amounts of vitamin D and subsequently improve the symptoms of nutritional deficiency. Some studies show initial improvements in hair loss after one month of taking the supplements, but regenerating activity normally returns after three months of daily vitamin maintenance. The good news is that hair loss due to vitamin D deficiency is often reversible.
Once vitamin D levels are increased, the hair follicles will normally begin to function properly and the hair will begin to grow again. New hair growth can take several months to become visible, so be patient while you wait for the results. Vitamin D3 deficiency, which is common in all regions of the world, is also a contributing factor and a major cause of hair loss. Like other cells in the body, hair follicles need a healthy supply of vitamins, proteins and other nutrients to function properly.
Each woman received oral vitamin D3 treatment (200,000 IU) every two weeks and a total of 6 doses were given to each patient. These hair loss problems are generally due to the interruption in the production of hair follicles, where vitamin D plays a crucial role. In addition to increasing your vitamin D levels, there are a few other things you can do to help with hair loss due to vitamin D deficiency. Vitamin D is mainly absorbed through exposure to the sun, but you can take dietary supplements and eat certain foods to increase your intake of the nutrient.
According to the National Institutes of Health, the ideal dietary amount of vitamin D for adults is 600 to 800 IU or 15 to 20 micrograms. The role of vitamin D3 is also evidenced by the fact that patients with vitamin D-dependent type II rickets generally have little body hair and often have alopecia all over the body and on the scalp. In a person's biological system, vitamin D participates in many processes that help maintain good health and well-being in general. The authors concluded that the overall response to oral treatment with vitamin D3 was satisfactory (85%) in terms of hair regeneration.
He was prescribed a daily dose of 1000 international units (IU) of vitamin D and, reportedly, in the first month of treatment, the amount of hair loss he experienced decreased. Vitamin D deficiency has been linked to alopecia, the autoimmune condition that causes areas of baldness on the scalp and other areas of the body. Along with vitamin D supplements, these alternatives are just one part of a larger list of treatments for hair loss. Vitamin D belongs to a class of fat-soluble vitamins that have multiple important functions in the body.
