Supplements & Vitamins for Hair Health

Certain vitamin deficiencies can cause thinning hair, brittle hair, and hair loss. While there are other factors such as age, genetics, and hormones that can also affect hair growth, having a good nutrient intake is of the utmost importance.

It is important to eat a well-balanced diet containing all of the 13 essential vitamins to help maintain hair health.

Below we have listed the best supplements and vitamins that are important for maintaining hair health.

Vitamin D

Supplementing with vitamin D will not directly improve hair growth and thickness, but if you are deficient in vitamin D, you may be harming your hair health without even realising it.

A research review in 2019 saw evidence that suggested there was a link between alopecia areata (which can cause severe hair loss and balding) and vitamin D deficiency. Many of the studies in this review saw that those who were suffering from alopecia areata were also experiencing low vitamin D levels. In the same review, there was also research that suggested those with lower levels of vitamin D saw more severe symptoms of alopecia areata.

Other studies also found that lower vitamin D levels can also be linked to female pattern hair loss – which is the most common type of hair loss in women. However, more research is needed on this in order to confirm this potential link.

The most common vitamin for hair growth and health is biotin (which is a B vitamin) and there have been a number of studies that have linked a biotin deficiency with hair loss in humans.

Even though biotin is used as an alternative hair loss treatment, it is those who are deficient in biotin that will yield the best results. Deficiency in biotin is rare though, as it is naturally occurring in such a wide range of foods.

The other B vitamins help to create red blood cells which will carry oxygen and nutrients to the scalp and hair follicles – which is a very important process for hair growth.

You can usually get enough vitamin B from your diet, as it is in many foods including:

  • whole grains
  • almonds
  • meat
  • fish
  • seafood
  • dark, leafy greens

But if you are either a vegetarian or vegan, you might not be getting enough from diet alone, so you may want to consider taking a supplement.

Vitamin C

Damage from free radicals can block growth, causing your hair to age – thankfully, vitamin C is a very powerful antioxidant that can help protect you against the oxidative stress that is caused by free radicals.

On top of this, our bodies need vitamin C in order to create collagen, which is a very important part of hair structure. You can read more about collagen by clicking here.

Additionally, vitamin C helps our body’s to absorb iron, which is a mineral necessary for hair growth.

Vitamin C can be found in a wide variety of fruits and veggies such as oranges and orange juice, peppers, strawberries, blackcurrants, broccoli, Brussel sprouts, potatoes, spinach, and many more.

Vitamin C is also available as an oral supplement and widely used by many, as part of a healthy diet, to complement their daily intake. Introducing vitamin C supplements into your diet is a great and simple way to boost your vitamin C intake if you struggle to get enough from your diet!

In a 2013 study, it was found that people who suffer from alopecia areata had significantly lower concentrations of vitamin E in their blood than those who did not have the condition.

Another study saw that people who supplemented with vitamin E for 8 months had a 34.5% increase in hair growth, whereas the placebo group saw only a 1% increase.

It is important to note though, that over-supplementing with vitamin E can cause hair loss and other side effects.
