In this article, we’ll give you all the information you need to choose the best hair growth supplement or vitamin for you. We’ll also present the top 5 products, according to experts in the fields of hair loss and dermatology.

Who Should Buy Hair Growth Supplements and Vitamins?

Supplements and vitamins for hair growth are for either men or women who have experienced some degree of hair loss, or serious shedding and breakage. According to Dendy Engelman, M.D. board-certified dermatologic surgeon, “Hair growth supplements are helpful for anyone who is experiencing hair loss, thinning, or for those who just want thicker or longer hair (1).”

Of course there are prescription remedies available, but these are brands are for consumers who are looking for a natural, organic solution which both supports growth and provides their hair with nutrients to boost its health.

Do Hair Growth Supplements and Vitamins Really Work?

Hair growth supplements and vitamins often do work, but of course it depends on the brand and the ingredients included. Products that work are rich in vitamins and other nutrients which support hair health and include substances that have research supporting their benefits. In the next section are some of the key ingredients you should look for in a hair growth brand.

What Are Some of the Ingredients in Hair Growth Supplements and Vitamins?

Here are some of the primary active ingredients in top hair growth supplements and vitamin products:

Biotin – This is a B vitamin, and it plays a particular role in hair growth. It can stimulate the production of keratin, which is the key protein making up the hair. This helps strengthen and grow the hair and nails and promote their health (2). A review in Skin Appendage Disorders explored the use of biotin for hair loss.

Saw Palmetto – This is an extract from the Serenoa Repens tree, and it plays a role in blocking the conversion of testosterone to the hormone DHT. As this hormone is responsible for hair loss, it may prevent shedding and promote growth and thickening. It also has anti-inflammatory agents which can reduce redness and swelling on the scalp (3). An article in the Journal of Cutaneous and Aesthetic Surgery discussed the role of saw palmetto in managing hair loss.

Iron – Iron deficiency is common in cases of hair loss, especially in women. Therefore, an increase in iron levels can help prevent loss and shedding (4). It also improves blood flow, which elevates scalp circulation and brings oxygen and nutrients to the follicles. An article in the Indian Journal of Forensic Medicine & Toxicology explored the role of iron deficiency in chronic hair loss (5).

Horsetail Grass – This plant is rich in flavonoids which are potent antioxidants that can repair damage to the hair and protect it from environmental stressors. In addition, it contains silica, which can promote hair growth as well as keep the hair shiny and healthy looking.

A study on rats in the Journal of Pharmacy & Pharmacognosy Research found that horsetail grass had hair regenerative properties (6).

Niacin – This is a vitamin in the B family, and it promotes hair growth and thickness by improving blood flow to the follicles. It can also deliver key nutrients and oxygen. A study in the Journal of Cosmetic Dermatology concluded that after 6 months of use, niacin led to a significant increase in hair fullness (7).

How Do Hair Growth Supplements and Vitamins Work?

Generally speaking, these formula contain a wealth of vitamins and nutrients which support follicle health and growth, as well as balancing the oils surrounding the follicle. A review in Dermatology and Therapy discussed the role of vitamins and minerals in hair loss (8). Many are rich in antioxidants, which destroy harmful free radicals in the hair and body and lower oxidative stress.

This assists in repairing damage to the hair and follicles, and it boosts its immunity. In addition, it protects it from potential harm from UV rays and various pollutants. Many of these supplements also have anti-inflammatory agents, which can decrease swelling and redness on the scalp.

Hair supplements often have ingredients which block the conversion of a hormone called DHT into testosterone. DHT is the specific chemical that leads to hair loss, so repressing it can have a significant impact.

They often contain proteins like collagen for hair growth, which also supports hair health and strength. There are ingredients which promote keratin production and help build its infrastructure. An article in the Journal of the Investigative Dermatology Symposium Proceedings discussed the role of keratin and other proteins in the human hair (9).

What to Consider When Buying Hair Growth Supplements and Vitamins

Selecting hair growth products is something you should do carefully, putting some research into it to make sure you choose the best supplements for you. We’ve prepared a simple guide to help you look for the right features when you evaluate a product.

Ingredients – Examine the ingredients included for some of the ones we have pointed out as being key hair loss organics. Naturally there are many others that also support hair health, so you should research each ingredient carefully and look at the studies supporting its efficacy.

Safety – You want to choose a product that has completely organic ingredients, without any chemical are artificial additives that could be harmful. These are usually listed under ‘inactive ingredients.’ In addition, check the safety practices of the company. Ideally you want a brand that manufactures in an FDA-approved facility and follows GMP standards.

Manufacturer – It’s always best to buy from a known and reputable manufacturer, as the product is more likely to be high-quality. If you can’t find any information on a manufacturer, it’s best to stay away from the product.

Price – Hair growth supplements and vitamins have quite a wide price range, starting from around $20 or less up to about $80. Check to see whether the ingredients and purported benefits justify the price. Some of the less expensive brands may also be effective.

Guarantee – Before you make a purchase, check that the company is offering a fair and reasonable return policy or satisfaction guarantee. In order to try out the product to see if it works for you, you’ll need at least 60 days.

Reviews – Always read through the reviews before you buy any product, to see what customers had to say. Look for the strengths and weaknesses of the brand so you know what to expect.

Tips For Enhancing Hair Health and Growth Naturally

Hair loss supplements and the best vitamins are ideal for supporting hair growth, thickening, and decreasing shedding and thinning. However, in addition, there are some lifestyle modifications you can make which could also have a strong impact on your hair health and growth. Consider incorporating some of these suggestions into your lifestyle.

Get a Scalp Massage – This is one of the best ways to stimulate your hair follicles, as well as improve circulation in the scalp. It can enrich overall scalp and hair health, and it may help to promote hair growth. The best thing about it is, if you have nobody else to give you one, you can massage your scalp yourself! Do this on a daily basis and you could see improvement.

Avoid Damaging Tools or Chemicals – If you use heat tools like curling irons and blow dryers, consider retiring them. Although they may help you style your hair, they can do a lot of damage and can cause breakage. The same is true of harsh chemicals, so check your products carefully to make sure they include only natural ingredients.

Quit Smoking – If you’re as smoker, it may be time to quit – or at least cut down – for the sake of your hair. The chemicals in cigarettes can slow circulation to the follicles and scalp, preventing the flow of oxygen and nutrients. This can damage your hair health, and it could also slow its growth.

Improve Your Diet – In addition to taking a supplement, you should be getting a lot of vitamins and minerals. Some of the best hair vitamins include D, A, C, E, and B vitamins. Minerals like zinc and iron are also good for hair growth, as well as protein.

In addition, include plenty of healthy fats like omega 3s in your diet, as they promote hair growth and health. This includes fish like tuna and salmon, flaxseed, plant oils like soy, and walnuts.

Holistic nutritionist Meryl Pritchard explains, “Healthy fats are essential to hair health, since our bodies can’t produce omega-3 fatty acids on their own. Therefore, it’s important to get these fats through our diet (1).”

You should also eat plenty of antioxidant-rich foods, to promote repair of damage to the follicles or scalp and protection from future harm. Examples are berries, dark chocolate, artichoke, kale, cabbage, and beans.

Work on Lowering Your Stress Levels

Stress can have a negative impact on every area of your body, and your hair is no exception. Having too much on your plate can speed up hair loss, so you definitely want to find a way to get it under control.

There are many ways you can do this, it’s just a question of choosing the right one, or more, for you. Consider starting an exercise program, taking a yoga class, getting regular massages, talking out your issues with a friend or counselor, working less hours, and many other possible remedies for high stress.

Get Your Hair Cut Regularly

It sounds counterproductive when you’re trying to grow your hair, but it actually makes perfect sense. You have to get rid of the split ends and unhealthy hair on the bottom so that your healthy hair can grow in faster. How often will vary from person to person but try to go for a trim every 2-6 months.
