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 make us feel isolated or different, it’s actually far more common than you may realise. For example, many millions of our counterparts in the US suffer from hair loss (approximately 80 million people, to be exact). [1]

The way our hair looks and feels can impact not only our physical appearance, but self-esteem and mood as well.* You might be wondering what causes this, exactly?

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 review chose to turn to dietary supplements. [2]

Certain vitamins and minerals are important for supporting hair health.

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

All hair supplements are NOT created equal.

Our Choice

4. Nourkrin Woman

by Nourkrin

PROS

• Features biotin, and horsetail extract
• 2 tablet serving size 

CONS

• 6 months daily usage minimum for desired effect
• No Keratin, Horsetail Extract, or Vitamins C + B6

BOTTOM LINE

Nourkrin Woman is a hair growth formula that has been formulated to help restore a normal hair growth cycle. It contains biotin, zinc and iron, as well as silica, and a patented ingredient Marilex®.

We do like the convenient 2 tablet serving size, however, Nourkrin states that one should take these tablets daily for a minimum of 6 months to see results, so if you’re looking for a quick boost to hair health and growth, this may not be the right product for you. 

B

GRADE

by Nutrafol

PROS

• Clinical testing for safety and effectiveness  
• With biotin, vitamin C, zinc and horsetail extract

CONS

• 4 capsule serving size
• Marine collagen (not suitable for seafood allergies)

BOTTOM LINE

Women's Hair Growth Nutraceutical by Nutrafol is an advanced hair care formula that comes in the form of four capsules per day. It features biotin, vitamins A, C, and D, and marine collagen as its primary ingredients. While this formula contains a wide range of ingredients, it is also formulated with marine collagen which means it may not be suitable for all consumers. Additionally, at 4 capsules per day, this may not be the most convenient supplement for most people's lifestyle. Lastly, this supplement may not fit many people’s budgeting needs, being priced substantially higher than the other products on this list.

2. Hair Growth Vitamins

by Viviscal

PROS

• Formulated with biotin, zinc, and iron
• 2 tablet serving size
• 3rd party lab tested

CONS

• No Vitamin B6
• No Keratin
• 14-Day returns policy

BOTTOM LINE

These hair growth vitamins by Viviscal are a solid choice for a hair health supplement. Similarly to Primal Hair, Viviscal have included some great ingredients such as vitamin C, biotin and zinc, in a convenient 2 tablet serving size. It must be noted however, that the formulation is missing a few ingredients that we would like to see added. Most notable is the absence of Vitamin B6, which supports the production of keratin. 

Overall, a solid choice, but due to the lack of keratin, we can't quite give it top marks.
