The Best Hair Vitamins of 2025

The Ultimate Guide: Hair Vitamins for Hair that Looks Full and Healthy

If you’ve started to notice more loose hairs on your clothing or caught in your hairbrush, don’t worry – you’re not alone. Although changes in our hair can feel very isolating, it’s actually far more common than you may think. For example, millions of men and women suffer from hair loss (approximately 80 million people in the United States, to be exact). [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. You might be wondering why does this happen?

What Can Affect Hair Health?

Hair quality tends to decrease with age, as our bodies produce less and less of the structural building block known as collagen, but this is just one of the many possible factors that can impact the way our hair looks and feels.

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. [2]

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.

The Stages of Hair Growth

1. Anagen: The growing phase

2. Catagen: The transition phase

3. Telegen: The resting phase

Popular solutions for hair such as extensions, wigs, chemical treatments, and topicals promise quick fixes that are often pricey, time-consuming, and can come with various side effects.

Certain vitamins and minerals are important for supporting hair health.

Here are some of the key hair-supporting ingredients to look out for:

Important Nutrients For 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.*

Always consult your physician or other qualified healthcare provider for accurate advice, diagnosis, and treatment plan. Individual results may vary.

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:

What To Try To Avoid In A Hair Supplement*

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.
