Knowing what hair vitamins and hair growth vitamins are good for your hair health is as easy as remembering your ABC’s. Seriously! Here are the hair vitamins usual suspects:

  • Vitamin A
  • B Vitamins (like Biotin and Niacin)
  • Vitamin C
  • Vitamin D
  • Vitamin E

Discerning the best hair growth vitamins and hair pills can be a bit more complicated, though, and it’s important to formulate your own, educated opinion before selecting a hair loss treatment to improve your hair health. Below, we detail the known hair vitamins out there, and what each hair vitamin is known to address.


Biotin is considered the most important hair vitamin by some, but many people wonder “Is biotin safe?” It does have its perks, but it is not as effective by itself as it is in conjunction with other vitamins in this list. Does biotin help hair growth? Yes, because biotin works by helping amino acids break down and encouraging protein synthesis. Proteins then break down into keratin, which we know is one of the main components of hair. What many people don’t know is that our bodies don’t need a ton of biotin to function properly, so when they take too much, they can actually cause more harm. Choose a reliable biotin product that has only the recommended dosage.


Vitamin A

Vitamin A is considered one of the “skin vitamins,” as it helps with wrinkles, dry skin, and other conditions. Part of the process of growing healthy hair is priming the scalp and hair follicles to hold onto the hair you grow, and Vitamin A helps to promote healthy cell growth in both the scalp and follicles (https://ods.od.nih.gov/factsheets/VitaminA-HealthProfessional/#h7).


Other B Vitamins

Other B Vitamins, as previously highlighted, Biotin is a well-known B vitamin used for hair growth. B Vitamins (including Biotin) are responsible for metabolizing protein. B6 is also responsible for regulating hormones (testosterone and estrogen). As fluctuations with these can cause hair loss, keeping your B6 levels steady is important. Niacin is another important B-Complex Vitamin, which maintains cell integrity and helps carry nutrients all over the body. All B Vitamins help your body absorb proteins and nutrients, so a full B-Complex Vitamin is ideal for hair growth. Remember, though, that too much of a good thing can be a bad thing. You don’t need a lot of B-Complex vitamins to improve your hair.


Vitamin C

Vitamin C strengthens the body’s immune system, which can fight off disease or illness causing you to lose hair. It also boosts the body’s ability to absorb iron (which is a component of healthy hair) and actually strengthens hair strands.


Vitamin D

Vitamin D is often called “the sun vitamin,” and you can get small doses from sitting outside. However, there is a lot of research being done on the importance of Vitamin D and the shocking deficiency that most people have in this crucial compound. Without enough Vitamin D in your system, your body isn’t able to absorb the nutrients and minerals it needs to function, which leads to disease. One of the most common signs of an unhealthy body? Hair loss.


Vitamin E

Vitamin E is one of the strongest antioxidants and anti-inflammatories humans have. It helps to remove free radicals that can kill our cells, which in turn helps us promote hair health, build our immune system, and improve our scalp condition. Vitamin E also repairs follicles and makes the hair smoother, making it one of the best vitamins for hair.
