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. People who think they have hair loss related to vitamin deficiency should not self-diagnose. The doctor can test for vitamin deficiencies, make recommendations about diets and supplements, and possibly recommend other forms of treatment.
It's also possible to have several types of hair loss at once, so it's important to get an accurate diagnosis. Vitamin and mineral deficiencies have been linked to hair loss. The most common deficiencies are iron, vitamin D and zinc. Deficiencies can be the result of a poor diet, blood loss, or a medical condition that affects how the body absorbs nutrients.
Overdosing on vitamins can also lead to hair loss. That's why it's important to get a proper diagnosis and ensure that nutrient levels are balanced. That said, he says that the three most common types of hair loss are telogen effluvium (mentioned above), alopecia areata (also mentioned above), and trichotillomania. Iron deficiency (ID) is the most common nutritional deficiency in the world and is a well-known cause of hair loss.
In addition to the most common causes of hair loss, Green says that living in a physically toxic environment can also cause hair loss. Screening tests are indicated for people with risk factors, since hair loss due to zinc deficiency can be reversed. The closest direct evidence of a relationship between vitamin D deficiency and hair loss is found in cases of alopecia areata (AA), in which immune cells attack hair follicles. Given the lack of human research, it's surprising that some hair loss supplements are marketed as containing selenium.
Skin effects include acral and periorificial dermatitis, while hair changes include TE and brittle hair. Researchers found that people with AA were more likely to be deficient in vitamin D and that lower levels of vitamin D increased the severity of hair loss (Gade, 2011). According to dermatologist Scott Paviol, the forms of alopecia that do not leave scars mentioned above are due to common cases, such as thinning hair due to life stressors (telogen effluvium), age-related hair loss (androgenetic alopecia) and autoimmune hair loss (alopecia areata). Medical and dietary history: risk factors that can cause nutritional deficiencies that contribute to hair loss.
More comprehensive studies are needed to clarify the role of vitamin D and the impact of oral vitamin D supplements on hair loss. In a literature review, no studies were identified on niacin levels in patients who only had hair loss. No clinical trial has demonstrated efficacy in treating hair loss with biotin supplements in the absence of deficiency. If you notice hair loss or your hair lacks shine, there's a chance that a vitamin deficiency is to blame.
