What You Should Be Looking For In A Hair Vitamin.

Our comprehensive research has revealed that a quality hair vitamin should have many, if not all, of the all-natural and clinically-studied ingredients listed below to support the hair repair cycle and promote new growth.

Did you know that up to 65% of the reviews on Amazon are fake?They're created by paid writers who, in many cases, don’t even try the product. Though checking reviews is important, we don't think it's safe to trust Amazon as a credible source of customer feedback. Relying on potentially fake reviews is a dangerous game to play when it comes to your health.

Repair And Protect The Scalp & Follicle.

If your hair is damaged, thinning or growing slowly, your follicles are most likely damaged or shrunken. Hair growth starts at the root, so it’s essential to keep your follicle and scalp healthy.

All-Natural Ingredients To Boost Scalp & Follicle Health:

  • Pantothenic Acid (B5) –– Supports the adrenal glands to stimulate hair growth and strengthen follicles.
  • Zinc –– Assists in nutrient absorption to sustain the glands that secrete oil and keep the scalp hydrated.
  • Biotin* -- Helps rebuild hair that's been damaged from over-styling and protects the scalp against harmful environmental factors.
  • Flaxseed Oil -- Nourishes hair follicles and regulates sebum oil production.

*The minimum clinically-tested daily amount needed for hair growth is 2500mcg.

Grow Stronger Hair.

Though the above ingredients can help with prevention and maintenance, only these clinically-tested ingredients have the studies to prove they can help reverse serious damage and even hair loss.

Clinically-Studied Ingredients Proven to Help Strengthen and Regrow Hair:

  • Tocotrienols –– A powerful form of Vitamin E that has been shown in two clinical studies to promote hair growth for those suffering from loss.
  • Keratin –– Studies have found that by supplementing with a bioavailable (more absorbable) form of keratin you could achieve longer hair in 90 days.
  • Saw Palmetto* –– A potent berry extract that naturally blocks the hormone responsible for hair loss, DHT, from being formed in the body. 

*Additionally, Saw Palmetto is the natural version of Minoxidil (the active ingredient in Rogaine).

Try to avoid cheap hidden synthetic fillers, binders and artificial ingredients. Many companies claiming to be all-natural will sneak them in. These ingredients are often found in the tiny print at the bottom of the label. Some have been linked to cancer and other serious illnesses. Try to avoid these synthetic additives: microcrystalline cellulose, magnesium stearate, gelatin capsules, silicon dioxide, chromium and artificial food colors.

Our Unique Research Procedure

We conducted in-house research to verify that the ingredients in the supplement were the same as claimed on the label. We also surveyed readers who have tried the product and learned from their experiences.

After months of analysis, we determined the best hair growth vitamin on the market today.

Rounding out our top 3 is NutraFol because it's packed with many of the essential vitamins we listed above such as folic acid, biotin, saw palmetto, and tocotrienols.

Users raved about the benefits of NutraFol for improving thinning hair and boosting overall health.

The company recommends it can be taken either as a preventative measure for potential hair loss due to aging or simply if you desire thicker, fuller hair.

Though this product had many stellar reviews, we do recommend proceeding with caution as a few users noticed stomach issues when taking NutraFol.

Overall, we love that the company has positive manufacturing practices and uses only all-natural, botanical ingredients.
