However, if you have a shortage of certain vitamins and minerals, like iron, then supplements can be a good way to keep your vitamin levels high. Some people find that certain vitamins help with hair loss, however there’s limited scientific evidence to support this. As with any type of hair loss, it’s important to treat the underlying cause.
Risk of Bias for the Included Studies
A recent review article evaluating biotin and its effect on human hair found 18 reported cases of biotin use on hair and nail. In ten of these 18 cases there was a genetic cause of biotin deficiency; the remaining eight patients had alopecia that was improved after they had taken biotin supplementation. There were three cases of uncombable hair syndrome, three cases of brittle nail syndrome, one case of alopecia due to valproic acid intake, and one case of an infant on a biotin-free dietary supplement.
Special Health Reports
They also have an increased risk of low birth weight babies and premature birth. Actively growing bodies need extra iron to provide energy to developing cells. That's why it's also important for babies, children, and teens to get plenty of iron. You can develop iron deficiency if you don't eat enough iron-containing foods or if you have trouble absorbing iron. Vegetarians and vegans may be more prone to iron deficiency, especially premenopausal females. This is because non-heme iron, the form found in plants, is not absorbed as well as heme iron, the form found in meat, poultry, and fish.
Vitamin D and AA
We’re not all “Popeye,” eating cans of spinach each day to stay strong.
Studies so far have found alopecia due to anemia may be something that largely affects women. Even if you do have low ferritin, taking too much iron can be problematic. It’s also possible to have low ferritin but normal iron readings. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
Causes of Iron Deficiency Anemia
To better understand the link between iron deficiency and excessive hair loss in women, a study examined more than 5,000 women aged 35–60. Among participants experiencing excessive hair loss or shedding, roughly 10% more had low iron stores compared to the remainder of the population (Deloche, 2007). While the science looks promising, further studies are needed to prove a link between iron deficiency and hair loss. You can usually correct iron deficiency anemia with iron supplementation.
What is iron deficiency anemia?
Evidence suggests that 50% of pregnant women are deficient in biotin [36]. The presence of biotin can in fact interfere with tests that use biotin–streptavidin technology. Exogenous biotin in the sample competes with biotinylated reagents for the binding sites on streptavidin reagents, creating false positive or false negative results [29].
Vitamin A
According to some research, hair follicle cells can be particularly sensitive to decreasing levels of iron and may not be able to grow new cells as effectively when iron stores are low. With treatment, you can help reverse both the iron deficiency and the hair loss. According to Healthline, other common types of alopecia include traction alopecia, telogen effluvium, alopecia areata, central centrifugal cicatricial alopecia (CCCA), and lichen planopilaris (LPP). If you’ve noticed an excessive amount of hair shedding, a receding hairline, or that the hair on the crown of your head becoming increasingly sparse, you’re probably experiencing a form of hair loss. Losing your hair can be a distressing experience, but you’re not alone.
Doktor notes that a common over-the-counter iron supplement, Slow-Fe, "is gentle on the stomach and won't cause constipation issues that can commonly arise with iron supplementation." The other treatment option that many people suffering from hair loss will choose is Follicular Unit Transplantation (FUT). We offer both of these treatments at Wimpole Clinic, creating impressive results for our clients. You can up your iron levels through a range of sources like lean protein, spinach and peas. Some cereals are also ‘iron-fortified’ which indicates they have higher amounts of iron.
This, along with other research, suggests that there may be a connection between hair loss and lack of iron stores in the body (Moeinvaziri, 2009). If your levels are very low, a doctor may recommend iron supplements. In some cases, you may need treatment for an underlying condition.
These researchers found no significant difference in folate and vitamin B12 levels between patients with hair loss and control patients [35]. Ramsay et al. reported a reduction in vitamin B12 levels in females with AGA treated with ethinyl estradiol and cyproterone acetate (Diane/Dianette and Androcur). This reduced vitamin B12 level resulted in vitamin B12-related anxiety, causing some patient to stop treatment.
The articles were obtained through the electronic library of Ben-Gurion University of the Negev. Two articles were received directly from the authors by email request. At the end of the process, 36 studies were entered into the systematic review and meta-analysis. The selection process is shown in the flowchart (shown in Fig. Fig.11). Meta-analyses were performed using the Metafor, Meta, and Demtar [8, 9] packages for R software (version 3.6.1) [10].
