The Four Best Vitamins for Hair Growth

There are some things you should know about the four best vitamins for hair growth that other health experts aren’t mentioning. Find out what they are here.

1. Biotin: Top Vitamin for Hair Growth

One of the most commonly researched vitamins for hair loss is biotin. Biotin is even added in shampoos for hair growth. It’s a vitamin that can become deficient if you add a few raw eggs to your smoothies every day, as there’s a biotin-destroyer within the raw egg that is inactivated with cooking.

Hair growth is essential for people who are in certain situations. For example, those who are taking epilepsy medications commonly need help with hair growth. Those who have stomach stapling or resectioning of the small intestine and stomach are prone to biotin deficiencies and commonly suffer from hair loss. This is one of those things that doctors won’t mention before you have weight loss surgery.

Interestingly, in one study at a university in Spain, children who had been taking drugs for epilepsy had normal levels of zinc, biotin and biotinidase but some of them had hair loss. Biotinidase is the enzyme that determines how well biotin is working in the body. Even though their levels didn’t prove they were deficient in biotin, their hair growth started up again with supplements of 10 mg biotin and the hair loss stopped. The high dose of biotin was enough to kickstart the hair growth. (J Child Neurol 2011 Dec;26(12):1522-4.)

There’s something else you should know about this vitamin for hair growth. Most B complexes skimp on biotin, so if your B complex or multivitamin provided you with anything less than 10% of the 300 mcg needed, there’s a good chance that your hair issues developed as a result of low biotin. For optimum hair growth, you may want to ask your doctor to run biotin tests on you and take a supplement – or just take it anyway with the aid of a nutritionist’s advice.

2. Folic Acid

Folic acid is one of my four best vitamins for hair growth.

Adding folic acid to the diet of those who want to experience hair growth or notice their hair is weak may be a good idea because of this vitamin’s functions in the body. Folic acid is important for cell turnover for both the red blood cells as well as other proteins in the body. A deficiency influences how fast hair grows and how thick it grows.

If you’ve been on a weight loss diet or if you don’t eat liver or leafy dark green vegetables like spinach, it’s easy to end up with a deficiency and thus hair issues. Poultry and pork as well as grains contain some folic acid as well.

When people take folic acid supplements for hair growth, they may take up to 10 mg a day. The vitamin is water-soluble so any excess is flushed out of the body. Read more about Folic Acid in this article.

3. B Complex Vitamins Needed to Balance Hair Growth Vitamins

Whenever you take high amounts of any of the B vitamins that help hair growth, you’ll have to insure that the rest of the B vitamins are balanced. Otherwise, you’ll create another B vitamin deficiency. The most logical thing to do is to have your doctor/nutritionist team evaluate all your B vitamin levels and then supplement appropriately with all B vitamins, not just the top vitamins for hair growth.

If you don’t have a doctor or nutritionist willing to help, you can still do this yourself. Did you know that you can order your own blood tests online now without a doctor’s ‘permission’? One place to order them is Purchase of the tests allows you a short consultation with a doctor on staff at Life Extension Foundation (

4. Vitamin D – Upcoming Best Vitamin for Hair Growth

In the last five years, there’s been an explosion of research studies on vitamin D. This long-forgotten vitamin is connected to just about every illness and turns on the genes for about 1000 different diseases, some of them related to hair loss.

Although hair loss is not a characteristic of vitamin D deficiency, the vitamin controls mineral balance in the body through vitamin D receptors. Zinc is one of those minerals controlled by vitamin D, and a zinc deficiency can cause hair loss with hair growth returning when zinc levels are restored. (Proc Natl Acad Sci USA 1997 Sep 2;94(18):9831-5.) Moreover, zinc regrows hair in those with hair loss when it balances the immune system cells CD4+ and CD8+. (Z Hautkr 1990 Feb;65(2):132-4.

In the next decade, we’ll discover more about this vitamin’s interaction and how it contributes to hair growth.

When you want faster hair growth, consider these top four vitamins but remember that the rest of the vitamins and minerals are important, too! All must be balanced for you to solve one challenge without creating another one.

    Many believe if you take this pill or that med, you will awake two days later and the results will be of a CHIA PET.
    Do your research on biotin.. as far as what the max your body you be taking daily. You don’t know what kind of damage, you’re doing, if any. The time it will take for your hair to reach the floor depends upon many factors. DIET & HEALTH!

    Good luck
