It certainly helps thicken existing hair, Levitan says. There is some evidence that having a vitamin D deficiency causes hair loss and other hair problems. Vitamin D stimulates the growth of hair follicles and, therefore, when the body does not have enough, the hair can be affected. 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. Fortunately, the effects of malnutrition on hair are reversible as long as you regain nutritional stability for 6 months or more. Once the deficiencies are corrected, the hair will grow back, although it may take some time.
If a medication is causing vitamin D deficiency or hair loss, the person should talk to their doctor about alternatives. Androgenetic alopecia, also known as male or female pattern baldness, is the most common cause of hair loss. These authors also stated that “we were careful to assess the difference in iron status in premenopausal and postmenopausal women with CTE versus FPHL and in each of these hair loss conditions versus controls with three different levels of serum ferritin.” Hair loss is considered a common problem in the dermatology community and has a profound negative psychological and emotional impact on patients. Given the role of vitamins and minerals in normal hair follicle development and immune cell function, large, double-blind, placebo-controlled trials are required to determine the effect of micronutrient supplementation on hair growth in those patients with micronutrients and non-healing alopecia to establish any association between hair loss and micronutrient deficiency.
Therefore, it is important to consider what form of vitamin A the supplements contain (carotenoids provitamin A or preformed vitamin A) and in what proportion. Certain vitamin deficiencies can cause hair loss, but correcting the deficiency can fix the problem. The role of nutrition and diet in the treatment of hair loss represents a dynamic and growing area of research. One of the most common causes of hair loss is malnutrition, when the human body does not receive the vitamins, minerals and nutrients it needs to function properly.
However, if you haven't eaten enough of these foods, you may suffer from a biotin deficiency, which causes thin hair and brittle nails. A poor diet can also lead to the loss of collagen in the scalp, which contains the hair follicles, because collagen is used to maintain body tissues. People often ask about vitamin and mineral supplements and diet as a means to prevent or control dermatological diseases and, in particular, hair loss. Body hair loss and the development of iron deficiency anaemia were reported in the “mask mouse” as a result of a mutation in the TMPRSS6 gene.
When it comes to hair growth, vitamin D is known to work by binding to certain receptors found in the hair follicle.
