Have you looked in the mirror recently only to realize that your once full and lustrous head of hair is now thinner than ever? If you said, “yes” then you’re not alone. In fact, tens of millions of men and women struggle with hair loss, and that number is expected to grow.

Experiencing hair loss can feel devastating, but the good news is that there are many naturally-derived ingredients that are shown to treat hair growth. That means it is possible to address your thin or thinning hair without having to rely on questionable ingredients.

Unfortunately, the demand to grow the hair of your dreams has led to a barrage of lackluster products full of empty promises, and if you pick the wrong one, you could be working against your hair goals. That's why more and more men and women are turning to hair growth supplements with premium ingredients.

So to help you get to a handle on the best hair growth supplements, Smarter Reviews has done extensive cross-market research and arrived at our top 5 quality hair vitamins for thicker, fuller hair.

Why Healthy DHT Levels Mean Healthy Hair

Stress, genetics, and age are all factors that contribute to hair loss. But the presence of DHT (dihydrotestosterone) is one of the most critical factors in male and female pattern baldness. When this hormone attaches to hair follicles, it can trigger them to shrink. Eventually, this leads to increasingly fine hair and, finally, to hair loss.

Now that you understand the importance of DHT in maintaining healthy hair growth, let’s figure out which supplement ingredients might have the biggest impact!

Look for These Supplement Ingredients 

Biotin

This popular nutrient protects hair due to environmental conditions.

Hydrolyzed Collagen

Collagen helps build keratin (the protein that makes up most of your hair) and promotes circulation to the scalp. More blood flow helps create new hair follicles, and repairs and strengthens existing hair. Collagen can also act as a natural antioxidant to protect against graying and further loss as you age.

Horsetail Extract

Horsetail is a traditional herb that’s high in naturally-occurring silica content. Hair fibers with high levels of silica tend to be stronger and less prone to shedding.

Zinc & Iron

Zinc helps keep your scalp hydrated which prevents dryness and flakes. Iron promotes blood flow to the scalp—allowing more essential nutrients to stimulate the scalp and hair follicles for proper hair growth—while low iron levels can cause hair to become dry, brittle, and even fall out. 

Ingredients to Avoid 

Magnesium Stearate

This "flow agent" may seem harmless, but in reality, it can work against your health goals. Unfortunately, most sources for magnesium stearate are genetically modified, and treated with high amounts of pesticides, due to its origins as a cottonseed oil base.

Titanium Dioxide

Widely relied upon in vitamin manufacturing as a coloring agent and binding mineral, it has been banned in food by the European Union due to genotoxicity concerns. Low-quality hair vitamin blends in the U.S. could include this filler.

At Smarter Reviews, we employ a comprehensive evaluation system to analyze and measure the value of products by looking at the ingredients, safety, projected effectiveness, return policies, and overall customer satisfaction. Here’s what made our list of the top 5 supplements for hair growth on the market today.

9.2/10

A

Overall Grade

PROS

  • Contains biotin
  • Non-GMO 
  • Includes horsetail extract

CONS

  • Short return policy
  • Lacks collagen
The Bottom Line

SuperHair by Moon Juice is packed with many of the essential vitamins and nutrients we listed above including biotin, horsetail extract, and vitamin A as well as iron and zinc. However, it lacks collagen which is a key ingredient if you are looking for the most effective hair growth formulation.

The product is also vegan and non-GMO which gives it an edge compared to some of the other products. On the the flip side, Moon Juice only offers a 45-day guarantee, which was lower than some others on the list. Still, this is a solid product, so SuperHair earns the #2 spot on our list.

8.9/10

B+

Overall Grade

PROS

  • Clinically studied ingredients 
  • Good for all hair types

CONS

  • Includes unnecessary fillers and binders 
  • Only offers returns within 30 days for open bottles
  • Mixed reviews 
The Bottom Line

Coming in at the number 3 spot on our list is Folexin's Hair Growth Support Formula.

This product was designed with a nutrient-rich formula that includes many key hair-growth ingredients including biotin and horsetail extract. Their well-rounded ingredient list is created in a facility that follows Good Manufacturing Practice which is something to look out for in a quality supplement.

However, Folexin uses less than ideal fillers in their formula, such as magnesium stearate. They also only offer a 30-day return policy for open bottles, which is why they ended up a little lower on our list in the #3 spot.

PROS

  • Contains vitamin A 
  • Includes iron + zinc

CONS

  • No Collagen
  • No Horsetail
The Bottom Line

Coming in at number 4 on our list is FoliGrowth by Advanced Trichology. This product is formulated with a potent blend of vitamins and minerals that meet our dosage recommendations.

Missing from the formulation, however, are some key ingredients, like collagen and horsetail, that really make the difference between a good and a great supplement, which is why we placed it lower on our list.

However, most customers reported seeing glowing results since starting this supplement, so we had to include FoliGrowth.

Total Ranking

8.2/10

B-

Overall Grade

PROS

  • Saw Palmetto + Horsetail

CONS

  • Contains fillers and additives
  • Limited ingredients
  • Mixed reports of effectiveness

 The Bottom Line

Landing at number 5 on our list is Propidren by HairGenics. This supplement is unique because it’s formulated specifically to block the factors that cause hair loss.

However, Propidren is low on potency and doesn’t have all the other vital ingredients that help your hair grow full and strong. This formula also uses fillers such as magnesium stearate.

Propidren offers a short money-back guarantee of only 30-days. There are other, more potent products on the market with more robust money-back guarantee offers. And with that it rounds out our list in the number 5 position.
