Biotin, also known as vitamin B, is an essential nutrient for the body's cells. Low levels of biotin can lead to hair loss, rashes, and brittle nails. It's important to get an accurate diagnosis from a doctor if you think you may be experiencing hair loss due to a vitamin deficiency. The doctor can test for vitamin deficiencies, make dietary and supplement recommendations, and possibly suggest other forms of treatment.
It's possible to have multiple types of hair loss at once, so it's important to get a proper diagnosis. Micronutrients are essential components of the normal hair follicle cycle and play a role in the cell renewal of cells in the matrix of the follicular bulb that divide rapidly. Vitamin D deficiency has been linked to alopecia, an autoimmune condition that causes baldness on the scalp and other parts of the body. A mutation in the TMPRSS6 gene was reported to cause body hair loss and iron deficiency anemia in the “masked mouse”.
People often ask about vitamins, minerals, diet, and supplements as a way to prevent or manage dermatological diseases, particularly hair loss. Vitamin B in all its forms (both water-soluble and fat-soluble vitamins) is important for healthy hair growth. There is anecdotal evidence that suggests vitamin E deficiency may have a negative effect on people with alopecia areata. In addition to biotin, other B vitamins are important for healthy hair growth, such as vitamin B6, B12, and folic acid.
Vitamin deficiency can become a “modifiable risk factor” in the development and prevention of thinning hair or alopecia, also known as hair loss. Depending on the cause of your hair loss, your doctor may prescribe medications such as topical minoxidil to reactivate hair growth. Medical history, existing damage to hair follicles, and family history may be as or more important than vitamin deficiency when it comes to the type of hair loss. Therefore, it is important to consider what form of vitamin A the supplements contain (provitamin A or preformed vitamin A carotenoids) and in what proportion.
Maintaining homeostasis and, by extension, the proper concentration of the active metabolite is essential for healthy hair. Popeye's spinach was a good representation of how vitamins can help with strength. Biotin deficiency can cause hair loss but there is no evidence-based data that shows biotin supplementation promotes hair growth. A lack of vitamin D can lead to symptoms such as hair loss.
