Hair loss can occur for many reasons, including genetics, vitamin deficiency, or underlying illness. If you're trying to regrow lost hair, the following vitamins may help.
Depending on the cause of the hair loss, some vitamins may work better for some people and other vitamins may work better for other people. Try finding a multivitamin with the following vitamins or add foods containing them to your daily diet.
Biotin is known as the "hair vitamin" for good reason. It promotes hair growth and prevents brittle, fragile hair. Severe biotin deficiency can lead to loss of hair, eyelashes, and eyebrows. (See 5 Best Biotin Supplements to see which ones rate highest according to reviews.)
Vitamin B12 is one of the most important vitamins for our hair and a deficiency can result in hair loss and premature graying. A surprising number of people are deficient in B12. Including enough vitamin C and iron in your diet will help you body absorb more B12.
Niacin (Vitamin B3)
Niacin improves circulation to the scalp and for this reason may have a positive effect on hair growth. Studies have found that niacin works better when combined with biotin.
Vitamin C prevents hair loss as well as premature graying, dryness, and brittle hair. If you're not getting enough vitamin C from your diet, you should take a supplement to make sure you're getting enough. (See 5 Best Vitamin C Supplements to see why you should avoid 80% of vitamin C supplements.)
Vitamin E helps to prevent and reverse hair loss thank to its ability to grow new blood vessels and increase circulation to the scalp. Topical vitamin E applied to the scalp may also help to regrow hair.
Vitamin D is beneficial for the whole body and this includes the scalp and hair. Also, vitamin D is necessary in order for the body to absorb calcium, which is essential for healthy follicles.
A vitamin A deficiency can lead to dry hair which can contribute to hair loss. Vitamin A stimulates the hair follicles and helps the scalp to produce sebum, which keeps the scalp and hair hydrated.
A zinc deficiency can lead to hair loss. Zinc contributes to cell regeneration, sebum production in the scalp, and protein synthesis.
Several studies have found that an iron deficiency, even if it's not so severe as to cause anemia, may cause or worsen hair loss. Researchers have found that women who develop hair loss have lower levels of iron than women who don't, especially when the hair loss is caused by alopecia. But the interesting thing is that the researchers found that no matter what the cause of hair loss, low iron levels can exacerbate the problem.
It is important to add that you should not take extra amounts of iron before checking with your doctor because too much iron can cause problems just as too little can. A visit to the doctor to have all of your vitamin levels checked, including iron and B12, will help you and your doctor to figure out exactly what is causing or contributing to your hair loss.
