Can low b12 cause hair loss?

Some research has shown that vitamin B deficiencies, specifically biotin, folate, niacin, riboflavin and B12, can cause hair loss. Vitamin B12, also called cobalamin, is a cofactor involved in essential body processes, such as cellular metabolism, DNA replication and the formation of red blood cells. Inadequate B12 diet or vitamin B12 malabsorption can result in a deficiency with a variety of signs, symptoms, and disorders. While the most notable impact of a deficiency affects the blood, gastrointestinal system, or nervous system, a deficiency of this vitamin can cause hair changes, including hair loss.

Vitamin B12 deficiency is a serious health condition, so consult your doctor if you suspect you have a deficiency. While vitamin B12 deficiency is sometimes linked to hair loss, there have been no clinical studies that have shown this to be true. Instead, hair loss, also called alopecia, is usually caused by genetics and age. It can also be caused by medical conditions, hormonal changes, some medications, and stress.

For example, one study found no significant difference in serum folate levels of patients with diffuse hair loss compared to controls. If you wake up in the morning and your pillowcase looks like there was a party the night before where a lot of your hairs didn't come home afterwards, combined with you not being able to see the bristles of your brush through the strands of hair, you might experience unwanted hair loss. This prescription medication for men is taken in pill form and, like minoxidil, can help decrease hair loss and help hair regrow. But regardless of the fact that hair loss in men is typical, when you notice it's happening to you, it can be disconcerting.

In India, we sought to detect the prevalence of various forms of hair loss in women and to correlate these data with hemoglobin and serum ferritin levels. People often ask about vitamin and mineral supplements and diet as a means to prevent or control dermatological diseases and, in particular, hair loss. One of the typical visible symptoms of iron deficiency is diffuse hair loss or thinning of the scalp. Most people lose between 50 and 100 hairs a day, and normally new hair grows back where old hair falls out.

By paying attention to your diet (including adding supplements as needed), you can generally avoid nutritional deficiencies that can lead to hair loss and really focus on vitamins, minerals and nutrients that can help healthy hair growth. If your scalp isn't rich in oxygen, not only are you likely to experience hair loss, but your hair follicles may not be able to sustain hair growth. On average, a healthy scalp has about 100,000 hair follicles that house a similar number of hairs, and if you lose between 50 and 100 hairs a day, it's simply normal hair loss, according to the American Academy of Dermatology (AAD). While essential vitamins and minerals are thought to play a role in hair follicle development, it's not entirely clear what role they play exactly.

Although the relationship between vitamin D levels and AGA or TE is still debated, most authors agree to supplement vitamin D in patients with hair loss and vitamin D deficiency. Despite vitamin B12's essential role in DNA replication and hair growth, there is little research linking a B12 deficiency to hair loss. .
