One of the most commonly known vitamins to promote strong hair is biotin, a B-complex vitamin that is sometimes referred to as Vitamin H. Biotin promotes healthy hair by increasing the hair’s elasticity and protects against dryness, which also helps prevent breakage.* In addition, Biotin helps produce keratin, a primary component of healthy hair.* Some even believe that biotin can slow down age-related graying.*
While Biotin deficiency isn’t common, some of the symptoms, which may alert you to the need to supplement, are hair loss (sometimes resulting even in eyebrow and eyelash loss), chronic conjunctivitis, dermatological issues, and even mild depression. Thankfully, deficiency and deficiency related symptoms are fixed simply by either taking it orally or by getting it through the following foods:
- Brown rice
- Green peas
- Brewer’s yeast
Vitamin A is a commonly known antioxidant also known as retinol. Its function is mainly to promote eye health*; however, it’s also widely used as a means to promote healthy hair. Vitamin A helps to produce healthy sebum, an oily substance secreted by the scalp, which keeps hair from drying out and breaking off.* In addition, Vitamin A fights free radicals that weigh your hair down.*
Vitamin A is found in the following foods:
- Cod liver oil
- Krill oil
Vitamin E, an antioxidant that helps neutralize free radicals,* is often referred to as the “good skin” vitamin,* but its assistive properties go far beyond the skin. Vitamin E also helps the body’s blood circulation by increasing oxygen uptake, which in turn aids the body in producing new hair.* In addition, some believe that Vitamin E has an affect on the body’s immune function, further increasing it's potential to reduce hair loss risk.* It can be taken by mouth, applied topically or can be found in the following foods:
- Leafy greens
- Wheatgerm oil
Pantothenic acid, also called Vitamin B5, isn’t a commonly known vitamin, but is highly effective in the prevention of graying due to aging. In addition, it can help reduce the natural loss of hair due to aging.* Pantothenic acid is believed to help strengthen hair follicles and their cells, allowing them to function properly. In addition, pantothenic acid also helps your scalp get rid of dead skin, clearing the way for new growth to occur.
Pantothenic acid can be found in many Vitamin B complex vitamins, but can also be found in various foods, such as whole grains and eggs.
The last vitamin that is important for healthy hair is Inositol. Inositol is, unofficially, grouped into the Vitamin B group of vitamins. It’s certainly not a commonly known vitamin, but is responsible for a number of support functions within the body.
Inositol aids in the health of cell membranes, particularly those in the eyes, intestines, brain, and bone marrow.* However, one of the most recent findings show that men who took an extra dose of inositol daily reported that their hair loss had improved, with less hair falling out.
While Inositol can be produced by the body through the natural process of breaking down glucose, it can also be found in the following foods:
- Citrus fruits and cantaloupe
- Whole grain breads
- Brewer’s yeast
