Everything you need to know about hair vitamins for locks that look full, voluminous, and healthy. Plus, see our picks for the best hair supplements of 2026.

If you feel like your hair looks thin, brittle, or dull, we know that can really get a person down. The state of our hair can impact not only our physical appearance but our self-esteem and mood.

What can affect hair health?

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 naturally changes with age. However, it can be influenced by a long list of other possible causes, and more often than not, it’s a mix of more than one.

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]

This is why identifying the root cause of hair problems is key, along with getting ample amounts of key vitamins and minerals. Always visit a medical professional for a proper diagnosis regarding any concerns you may have with your hair..

BOTTOM LINE

Taking the third place spot on our list is Women's Hair Growth Nutraceutical by Nutrafol. This hair formula comes in the form of four capsules per day and features biotin, vitamins A, C, and D, and marine collagen as its primary ingredients. This formula contained a wide range of natural ingredients, however it is also formulated with marine collagen which means it is not suitable for those who can’t consume seafood. Additionally, the 4-capsule per day serving size wasn’t as convenient to take as we would have liked. Finally, some thought the product was on the pricier side.

SuperHair by Moon Juice is our number two pick.

This beauty blend also contains the minerals zinc and selenium as well as MSM and plant extracts from rosemary, nettle, lutein, and horsetail.
