There are many reasons why people may experience changes in the way their hair looks and feels and, although it can feel very isolating, it’s actually far more common than you may think. That’s why some are turning to hair formulas to regain what was lost. But with only a small percentage of brands out there with products that actually work, which one should you choose?
According to a review conducted by the Council for Responsible Nutrition in 2021, supporting hair health was one the top 5 reasons adults in the USA chose to turn to dietary supplements.[1]
The way our hair looks and feels can impact not only a person’s physical appearance but their self-esteem and mood as well. Hair thinning is, unfortunately, something that many women and men may have to deal with at some stage in their life. For example, approximately 30 million people in the United States suffer from some form of hair loss. [2]
What Can Affect Hair Health?
The way our hair looks can be greatly influenced by a long list of possible causes. Anything from stress to genes to nutrition can impact hair health. More of than not, changes result from a combination of different factors.
Common Factors That May Impact Hair Health*
- Genetics*
- Age*
- Poor diet*
- Unhealthy lifestyle choices*
- Environmental factors
- Digestive issues*
- Stress or shock*
- Damaging hairstyles*

Always visit a medical professional for a proper diagnosis regarding any concerns you may have with your hair.
The Stages of Hair Growth
1. Anagen: The growing phase
2. Catagen: The transition phase
3. Telegen: The resting phase
Some factors, like genetics or aging, are out of our control. That being said, there are certain steps you can take to feel more in control of your hair.
What Can Be Done About It?
A variety of nutrients are thought to help support hair health.* [4] The “inside-out” approach is popular among many because opting for more extreme and expensive treatments may involve harsh chemicals or cost a lot of money.
Studies in recent years suggest that, when combined with a healthy lifestyle, certain vitamins and minerals in the right proportions can help to regain what was lost.*[4]
When it comes to less hair acting sooner than later is key. Prevention is just as important as reversal when it comes to hair. So if you’re wondering whether you should start your course of supplementation, the answer is yes. The longer you wait the less likely you will be able to prevent and regain.
Here are the top ingredients thought to support hair health*:
Top Nutrients For Supporting Hair Health*
- Biotin — Also known as vitamin B7, biotin is often used to support hair and nail health. Researchers believe that there is a link between biotin deficiency and hair health. This nutrient plays an important role in healthy cell formation and is essential for the healthy metabolization of fats, amino acids, and carbohydrates.* [3, 4]
- B-Vitamins — These essential vitamins help to carry out a number of processes in the body and are also important for supporting hair health.*
- Horsetail Extract (Silica) — This extract is a natural source of silica, a mineral composed of silicon and oxygen, which is important for healthy collagen. Research suggests that horsetail extract may support hair strength and shine, as well as scalp health.* [5]
- Vitamin C — This antioxidant-rich vitamin possesses numerous benefits for healthy hair. It is used by the body to protect against oxidative stress, support skin (and scalp) health, and is also needed to create collagen. Vitamin C helps the body absorb iron, an important mineral for hair health and overall wellness.*
- Zinc — Zinc is a trace mineral that is important for maintaining hair and scalp health.*
- Keratin — This is the main type of protein found in hair which is responsible for the strength and elasticity of hair and is essential for maintaining healthy hair.*
- Collagen — Collagen is the most abundant protein in the human body and is key for maintaining skin and scalp health.*
All hair supplements are NOT created equal.
Unfortunately, some generic hair supplements may not meet your needs or expectations.
Here are some factors to try to avoid when shopping for a hair supplement:
Top Nutrients For Supporting Hair Health*
- Not Third-Party Tested — Choose a hair supplement that has been independently third-party lab tested and manufactured in the USA to guarantee premium quality and safety.
- Titanium Dioxide — A food coloring agent widely used to whiten supplement capsules.*
- Artificial Flavors — Avoid hair supplements that contain artificial flavors. These products may contain ingredients such as high-fructose corn syrup, artificial sweeteners, and other unnecessary additives.
