Many brands sell vitamins for hair, skin, and nail health. They contain different ingredients that might help prevent hair loss, hydrate the skin, and strengthen the nail cuticle. Some are also vegan-friendly and gluten-free and are free of artificial colors and preservatives.

This article looks at some potential benefits of hair, skin, and nail vitamins and products available from online providers. It also explores factors that can help a person choose the right vitamins.

Hair, skin, and nail vitamins contain these ingredients:

  • Vitamin A: The University of Rochester Medical Center states that vitamin A can prevent skin dryness that could lead to infections. Supplements may be effective in reducing the risk for skin, breast, and lung cancer. It can also support sebum production, which prevents hair breakage. However, a 2017 study found that over-supplementation of vitamin A can lead to hair loss.
  • Vitamin C: This can be beneficial for wound healing. According to an older study, doctors may recommend vitamin C supplements for people who are recovering and have low vitamin C levels.
  • Vitamin E: A 2016 article states that Vitamin E has anti-inflammatory effects and can reduce skin thickness and edema. It can also protect the skin from UV radiation.

Some products also contain biotin, a B-complex vitamin. A 2015 study reviewed the effects of an oral marine protein supplement which contained biotin and other ingredients, in women who had thinning hair. The researchers found that the 90-day treatment led to hair growth and decreased hair shedding.

In addition, hair supplements may also include the following ingredients in their formula:

However, there is limited scientific evidence on the benefits of hair, skin, and nail vitamin supplements.

Furthermore, one study found that vitamins available to buy over the counter (OTC) at retail stores may not be safe for people, as they can interact with other drugs and lead to overuse. Some supplements may not include a pregnancy warning label, stating that individuals who are pregnant should see a doctor before taking any medications or supplements.

The Food and Drug Administration (FDA) does not have the authority to approve supplements. As a result, it recommends that people use noncommercial sites when looking for these types of products.

Ideally, look for supplements that have been tested by third-party labs and avoid buying supplements if the label says that they do not cause any side effects or provide more benefits than a prescription drug.
