 What Vitamin Deficiencies Cause Hair Loss?

Learning more about the vitamin deficiencies that lead to hair loss can help you narrow down the solution to stronger, fuller hair.

Here are some common deficiencies that may cause hair loss.

Vitamin D

Vitamin D deficiency can lead to hair loss, as this critical vitamin is helpful when it comes to stimulating your hair follicles and keeping your strands strong and healthy. Vitamin D affects the growth and differentiation of keratinocytes. Evidence shows that vitamin D has immunoregulatory and anti-inflammatory effects. For this reason, low levels of vitamin D have been linked to alopecia areata.

Vitamin C

Antioxidants are essential for maintaining healthy hair and overall health. One vitamin that can help with this is vitamin C, or ascorbic acid. It’s a powerful antioxidant that everyone needs to support the immune system and fight damage caused by free radicals and oxidative stress. Because it aids in the synthesis of collagen fibers, a deficiency can lead to dry, brittle hair.

 Vitamin B7 (Biotin)

Do you feel that your hair is increasingly weak, brittle and falling out? Another vitamin, biotin (vitamin B7), is to blame. If you are deficient in biotin, you may experience hair loss as a side effect/symptom. Alternatively, if you experience increased shedding, you may be suffering from alopecia. Biotin also helps the body metabolize fatty acids. Therefore, a lack of biotin can impair your body’s ability to use your omega-3 and omega-6 fatty acids.

Vitamin B5 (pantothenic acid)

B vitamins are needed to assemble the red blood cells needed to carry oxygen to the scalp, which helps create new hair from the follicles. One of the important B vitamins that are vital for fighting hair loss is vitamin B5. This vitamin can promote hair growth. Because of this benefit, several different hair products contain vitamin B5.

Vitamin A

Another essential vitamin to support healthy hair is vitamin A. Vitamin A deficiency could destroy hair follicles and cause hair loss. Because of this, hair growth is stunted, leading to thinner hair.

Vitamin E

Vitamin E deficiency is rare but still possible. This essential vitamin helps promote oxygen circulation in the body and protects against free radical damage, so the scalp will be healthy and hair follicles will thrive.

Fatty acids

Omega-3 and omega-6 fatty acids are important fatty acids that promote hair growth. A deficiency of these essential fatty acids can lead to hair loss on the scalp and eyebrows.

Other vitamin deficiencies that can contribute to hair loss

While the above vitamins may be the main cause of hair loss, there are a few other vitamin deficiencies that you should be aware of. Folic acid or low iron can also cause hair loss because they play a role in healthy cell growth and nutrition.

If you think you may be suffering from a vitamin deficiency, talk to your healthcare provider about a diagnosis and treatment plan.

Vitamin D.

Some of the foods you might consider adding to your diet to increase your vitamin D intake include salmon, eggs, cheese, and beef liver. Milk, cereal, bread, and some yogurts can contain this important vitamin if they are fortified with it (which is fairly common here in the US). Being in the sun is also a great way to get some vitamin D because UVB rays help your body synthesize vitamin D. However, it’s possible that being in the sun without sunscreen could damage your skin, so it’s best to take vitamin D.

Vitamin C.

Vitamin C is not stored in the body. Humans are naturally deficient in an enzyme known as L-gulonolactone oxidase, which is necessary for the synthesis of vitamin C. Therefore, you must obtain it through your diet. Some foods that are full of vitamin C are citrus fruits, spinach, green and red peppers, Brussels sprouts, broccoli, and potatoes.

B vitamins are also important for healthy hair. Foods that contain biotin (B7) include meat, eggs and nuts. Potatoes, nuts, beef, chicken, eggs and dairy products are rich in vitamin B5.

Vitamin A

It is also another vitamin you’ll want to make sure to support your hair. Orange-colored fruits and vegetables, such as pumpkin, squash, sweet potatoes, and carrots, usually contain good amounts of vitamin A.

Vitamin E.

Foods rich in vitamin E include leafy greens, seeds, nuts, and oils such as canola. Corn and soybeans can also play an important role in obtaining vitamin E.

What dietary supplements can be used for hair loss?

Narrowing down what vitamins you’re lacking will help you decide what supplements can help. Here are some supplements that can help promote the health of your hair.


Iron is essential because it is responsible for aiding the formation of hemoglobin. A lack of iron can slow down the oxygen that is carried by the body. This directly affects the nutrients entering the cells, which could inhibit the growth of hair follicles and shafts, leading to hair loss.
