In most cases, a balanced diet will supply a healthy amount of vitamin A [ 14]. The recommended dietary allowance of vitamin A for adults aged ≥ 19years is 1300 mcg/day (4300 IU [international units]) for U.S. populations. While there is no upper intake level for provitamin A carotenoids, ingestion of very high levels of preformed vitamin A can be toxic. For adults aged ≥ 19years, the tolerable upper intake level of preformed vitamin A is 10,000IU [ 13]. It is therefore important to consider what form of vitamin A is contained in supplements (provitamin A carotenoids or preformed vitamin A) and in what proportion. The human scalp contains approximately 100,000 hair follicles. Of these, 90% are in the anagen phase, where there is no alopecia, requiring essential elements, such as proteins, vitamins, and minerals, to efficiently produce healthy hair [ 3, 4]. Micronutrients, including vitamins and trace minerals, are therefore crucial components of our diet [ 5]. According to Stewart and Gutherie [ 6], in 1497 Vasco de Gamma recorded the deaths of 100 of his 160 sailors due to scurvy and 300years later James Lind linked scurvy with vitamin C deficiency, noting skin hemorrhage and hair loss [ 6]. In protein-energy malnutrition, skin and hair changes are prominent, as seen, for example in children with kwashiorkor, marasmus, and marasmic-kwashiorkor conditions [ 7]. A severe reduction in carbohydrate intake results in hair loss [ 8].

Maybe you’re not worried about biotin deficiency but wonder whether a biotin supplement could help you get amazing hair. After all, many products advertise biotin as a hair growth booster. In addition to the role biotin plays as a cofactor in various carboxylation reactions, recently, it has been observed that biotin plays important roles in gene expression and immune mechanisms. [20] [19] More recently, a cross-sectional study conducted by Gade et al. sought to assess serum vitamin D levels in patients with AA as compared to healthy controls, and to further identify the association between vitamin D levels and disease severity in patients with AA. The study included 45 adult patients with AA and 45 control subjects. Serum vitamin D was estimated using enzyme-linked immunosorbent assay (ELISA) kits. The severity of AA was determined using the Severity of Alopecia Tool (SALT) score. The mean vitamin D level was found to be significantly lower in patients with AA (17.86±SD 5.83ng/mL) than in the healthy controls (30.65±SD 6.21ng/mL) ( p=0.0001). The level of vitamin D showed a significant inverse correlation with disease severity ( p=0.001) [ 70]. Venton et al. described the loss of pigmentation of the hair in four patients receiving TPN without selenium supplementation. The serum and hair selenium levels were 38±11ng/mL and 0.34±0.13μg/g, respectively. Hair started to re-pigment after 6–12months of therapy with intravenous selenium [ 117]. Similar findings, including alopecia with pseudoalbinism, were found in 6 infants receiving nutritional support. In these six infants, after starting daily selenium therapy (5μg/kg/day), selenium serum levels returned to the normal range of 5–15μg/dL, and alopecia and pseudoalbinism improved [ 118].

If your goal is for biotin to help your hair grow, you may consider adding a biotin shampoo into your wash routine. Sounds like an easy fix, right?

Biotin, Zinc Oxide, Bulking Agent (Dicalcium Phosphate, Microcrystalline Cellulose), Anti-Caking Agents (Magnesium Stearate, Silicon Dioxide). Directions Biotin is part of the “B family” of vitamins and is also known as vitamin H. It’s a B complex vitamin that helps your body convert food into energy. The word “biotin” comes from the Greek word “biotos.” It means “sustenance” or “life.” Biotin is a crucial nutrient for good health. Vitamin B2 (riboflavin) is a component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) [ 22]. FMN and FAD represent 90% of dietary riboflavin, and both play roles in cellular development and function, metabolism of fats, and energy production [ 23]. The body stores only small amounts of riboflavin, in the liver, heart, and kidneys. Riboflavin deficiency—while extremely rare in the USA—can cause hair loss [ 24].Frontiers in Nutrition: “Influence of biotin intervention on glycemic control and lipid profile in patients with type 2 diabetes mellitus: A systematic review and meta-analysis." And if you can’t find the mega B-vitamin combination, you can buy biotin, zinc and vitamin C separately. Biotin shampoo BnD causes abnormalities in the fatty acid composition of skin, such as accumulation of odd-chain fatty acids and abnormal metabolism of long-chain polyunsaturated fatty acids [ 4, 23, 24]. In this study, we found that dietary BnD leads to ZnD. However, the decline in the serum zinc levels in BD mice was relatively slower than that in ZD mice [ 8]. Accordingly, although changes in terms of the body weight and survival rate were similar to those observed in ZD mice, the kinetics in BD mice was slower than that in ZD mice [ 8]. LCs were found to be almost absent in the epidermis of BD mice, thereby leading to enhanced ATP production in skin, and similar findings were observed for ZD mice. This aberrant ATP accumulation in the skin results in the recruitment of neutrophils [ 25] and development of characteristic skin lesions in patients with ZnD and BnD. Indeed, decreased serum zinc levels have been reported in some patients with BnD [ 26, 27, 28]. On the other hand, some studies have demonstrated normal serum zinc levels in patients with BnD [ 29, 30, 31]. We speculate that this discrepancy might be attributable for the duration of BnD. Reduced serum biotin and zinc levels have been recently reported in patients with male androgenetic alopecia, suggesting the close association between biotin and zinc [ 32]. We investigated how dietary BnD led to ZnD but the precise mechanisms could not be elucidated (data not shown). Further analysis is required for elucidating the underlying mechanisms. It’s true that many shampoo brands utilize biotin in their formulas as a way to combat hair loss. However, similar to the res earch around biotin supplements, the data to support hair growth from biotin-infused shampoo is limited. But there’s no harm really in giving this kind of shampoo a try if you want your hair to feel fuller — but don’t expect a magical regrowth of hair. Possible side effects of biotin

The Role of Vitamins and Minerals in Hair Loss: A Review

While taking biotin supplements is fairly common and safe, there are a few side effects to be aware of. Sometimes, adding a high supplement of biotin into your diet can result in you having an upset stomach, as your gut adjusts to the new levels of vitamin.Nutrition is at the top of the list. Biotin and zinc are essential nutrients that can help keep your hair healthy and shiny. If you have thinning or dull, lifeless hair, these hair vitamins may be the perfect solution. Prolonged use of oral antibioticsmay also lead to biotin deficiency. The most likely underlying mechanism is the inhibition of intestinal flora, leading to reduced biotin production. Another possibleexplanation isthe antibiotic-driven overgrowth of biotin-consuming bacteria. [12] Alopecia is a well-known sign of established zinc deficiency with hair regrowth occurring with zinc supplementation [ 122], [ 123]. Data correlating zinc levels with TE and AGA are, on the other hand, not homogeneous. A retrospective cross-sectional study of 115 subjects diagnosed with TE (acute and chronic) found that 9.6% of subjects had zinc deficiency [ 48]. Another study comparing 312 subjects with hair loss (including AA, MPHL, FPHL, and TE) with 32 controls showed low levels of zinc in patients with AA and TE. These authors recommended zinc replacement if levels were < 70µg/dL [ 124]. However, this finding was not confirmed by a recent study of 40 patients with CTE, with 30 healthy subjects as controls, with the authors finding no difference in zinc levels between the affected and control patients.
