Best Supplements for a Fuller Head of Hair in 2022

What to Look for & Avoid, plus our Top 5 Vitamins for Healthy DHT Levels

Advertiser Disclosure

Pharmacy aisles overflow with men’s hair growth products offering everything from healthy DHT levels to a robust hairline. In 2021 alone, the American hair loss industry will spend US$ 3.3 billion to get your attention with tongue-twisting, over-the-counter options like finesteride and minoxidil as well as hormone-disrupting shampoos.

So why aren't we all walking around with flowing manes of hair? And with so many ineffective treatment options out there, where do we even begin to understand which are the best hair loss products for men, especially when healthy DHT levels are a concern?

The truth is that many informed shoppers today are turning to naturally-derived supplements that offer a health-first, long-term solution for men who struggle with hair loss.

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

Benefits of a Quality Hair Supplements

Promote healthy DHT levels

Improve hair growth & scalp health  

Minimizes follicle breakdown due to oxidative stress  

Prevents clogged follicles & regulates scalp oil production

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 pattern baldness and hair loss. 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 be having the biggest impact!

Look for These Supplement Ingredients 

Saw Palmetto

Saw palmetto is a potent berry extract that plays a key role in promoting healthy DHT levels. This naturally occurring hormone contributes to the normal thinning of hair associated with age by shrinking hair follicles.

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 medicinal herb that’s high in silica content. According to clinical studies, hair fibers with high levels of silica are less likely to fall out.

Zinc & Iron

Zinc helps keep your scalp hydrated by preventing dryness and flakes. Iron increases blood flow to the scalp—allowing more essential nutrients to stimulate the scalp and hair follicles for improved 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 be very dangerous. 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, titanium dioxide is known to cause health issues in the immune system. Low-quality hair vitamin blends typically 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 DHT supplements for hair growth on the market today.

2. Nutrafol For Men

Total Ranking

9.2/10

A

Overall Grade

PROS

  • Promotes healthy DHT levels 
  • 30-day, risk-free, money-back guarantee

CONS

  • Price is much higher than competitors
  • Unclear dosage information 
The Bottom Line

NutraFol Hair Vitamins for Men is packed with many of the essential vitamins and nutrients we listed above including saw palmetto and hydrolyzed collagen.

However, the label fails to list how much of these ingredients are in each serving, which makes us wonder if customers are receiving proper clinical dosages of the product.

On the plus side, this product engages in positive manufacturing practices and uses only naturally-derived, botanical ingredients.

However, the price point is higher than the other hair supplements on this list at $88.

3. Viviscal Man 

Total Ranking

8.9/10

B+

Overall Grade

PROS

  • Addresses hormonal changes 
  • Clinically studied ingredients 
  • Good for all hair types

CONS

  • Includes unnecessary fillers and binders 
  • Mixed reviews 
The Bottom Line

Coming in at the number 3 spot on our list is Viviscal Man Maximum Strength Hair Nourishment System.

This product was designed to address hormonal changes, nutrition deficiencies, and everyday stresses that could cause hair loss. Viviscal uses potent ingredients that are back by 5 clinical trials and claims to be suitable for all hair types.

However, reviews are mixed… many customers were happy with their results, but some said they didn’t see any results after 3 months.

Viviscal also uses potentially harmful fillers in their formula, such as magnesium stearate.

4. FoliGrowth

Total Ranking

8.5/10

B

Overall Grade

PROS

  • Promotes healthy DHT levels 
  • 30-day, risk-free, money-back guarantee

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 -- including saw palmetto -- 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.

5. HairOmega 3-in-1 Hair, Skin & Nail Formula

by DrFormulas

By DrFormulas

Total Ranking

8.2/10

B-

Overall Grade

PROS

  • Impressive dose of vitamins & minerals
  • Vegetarian-friendly

CONS

  • High serving size
  • No Collagen

 The Bottom Line

The well-respected DrFormulas HairOmega 3-in-1 line of vitamins deserves recognition for their impressive amount of hair healthy vitamins and minerals and praise-worthy adherence to quality manufacturing practices.

By contrast, notable ingredient hydrolyzed collagen is completely absent in the HairOmega formulation, which left us questioning the product's long term effectiveness in maintaining a robust hairline. Many reviewers also noted the high serving size -- 4 capsules per day, twice what most other competitors suggest.

HairOmega 3-in-1 by DrFormulas, however, is delightfully vegetarian-friendly, and with that it rounds out our list in the number 5 position.
