Best Hair Growth Supplements – Top Hair Vitamin Pills to Buy

Having healthy, natural hair is one of the ways to develop a positive outlook. With good hair growth vitamins and natural hair care supplements, you can transform your appearance. Natural hair growth supplements contain ingredients that can help revitalize and rejuvenate hair.

Some hair growth formulas even make your hair look younger, while others strengthen hair from the follicles. Regardless of the reason for applying a natural hair growth supplement, there is a range of options to choose from. All the same, consumers need to be careful about what they buy to improve hair growth.

To help bridge this gap, our editorial team analyzed various hair growth products and other supplements on the market.

Users should take one capsule of the supplement with breakfast and another with dinner to promote hair growth throughout the day.

Significantly, Folital strengthens users’ hair and claims to eliminate hair loss and purify and detoxify hair. Besides, it claims to combat inflammation and free radicals within the hair cells for easier absorption of nutrients, among other benefits.

A product of Zenith Labs, Hair Revital X claims to be an exceptional remedy for erratic DHT—a hormone that controls hair loss.

Clinical Formula Hair Vitamins claims to support healthy, natural hair growth and shine. It uses natural ingredients such as amla berry, reishi mushroom extract, Vitamin E, Saw palmetto, and hydrolyzed collagen alongside other elements.

Foligray

This nutritional supplement uses folic acid, copper, and biotin to promote hair pigmentation and healthy hair. Unlike most products on this list that focus on hair growth and quality, Foligray focuses on hair pigmentation. The supplement delivers vitamins, minerals, and nutrients to nourish hair pigmentation at the follicle and cellular levels.

According to the manufacturers, Foligray contains an enzyme known as catalase, which helps reduce the levels of hydrogen peroxide. Hydrogen peroxide can affect hair color significantly when catalase levels drop as one’s age advances. Foligray provides the catalase needed to affect hair pigmentation as one gets older.

Hair La Vie’s Renewing Growth Treatment

The Renewing Growth Treatment supplement is the third product from the Hair La Vie brand. This formula delivers a potent blend of ingredients that give users stronger and denser-looking hair. Since it’s a serum, it works faster than a dietary supplement. The hair and scalp absorb the ingredients more quickly.

According to the manufacturer, Renewing Growth Treatment can increase hair volume and keep it tangle-resistant “instantly.” Each supplement bottle is packed with ingredients and plant extracts that promote hair growth in multiple ways. The supplement uses ingredients such as Ecklonia cava, Cap Auxein G2, Capixyl, AquaCat, and Procataline, alongside other ingredients.

Kintsugi Amplifying Glaze

The Amplifying Glaze supplement from Kintsugi hit the market in 2021. Like other serums, this ingredient coats the hair with vitamins, minerals, and nutrients to support growth in multiple ways. The manufacturer advises users to apply the weightless serum daily to give their hair a nourishing all-in-one treatment with a flexible hold.

Besides, Kintsugi’s Amplifying Glaze contains ingredients that support a thicker, fuller, denser and more voluminous crop of hair from the beginning to the end of each strand. The manufacturer uses a mix of therapeutic protein compounds, marine extracts, and premium polymers to deliver these benefits.

The Amplifying Glaze serum nourishes the scalp and hair with the ingredients that support hair growth from the follicle. This helps combat dullness and breakage to give hair a shiny quality.

Kintsugi KeraNew

The KeraNew is the second supplement from Kintsugi on this list. Unlike the Amplifying Glaze, a serum, KeraNew is a dietary supplement that promotes hair growth from the inside out. Users should take the supplement daily to fight the signs of aging hair, utilize the power of protein, and nourish the scalp. Besides, the supplement helps strengthen the strands to make hair look fuller, healthier, and more youthful.

Nutrafol Women

Nutrafol Women (Nutrafol Hers) is a nutritional formula specifically designed for a woman’s body. The product won the 2018 Best of Beauty Breakthrough award organized by Allure Magazine.

Nutrafol Women utilizes natural ingredients including marine collagen, ashwagandha, tocotrienol complex, and other ingredients that support hair growth in different ways to deliver the said benefits. Some elements in Nutrafol Women are adaptogens that help the body’s response to stress to grow hair quickly. Collagen is the most abundant protein in the hair and body that supports hair growth in different ways.

Viviscal

Viviscal is another hair growth supplement that is worth considering in 2021. The supplement claims to help men and women restore healthy hair in as little as 90 days. Besides, the supplement is one of the most-studied hair care brands on this list. So far, up to ten published clinical trials support the formula.

In the clinical trials, users witnessed a 32-percent increase in hairs and a 39-percent decrease in hair shedding. Viviscal users also experienced a 92% increase in hair thickness after three months of use.

According to the images posted on Viviscal.com, men and women have reversed significant hair loss by taking Viviscal. The supplement claims to work by supplying the necessary nutrients to the follicles across four stages to give users significantly thicker hair in as little as 90 days.

While they don’t work for everyone, hair growth products from Viviscal, including supplements, Densifying Shampoo, Densifying Conditioner, and the Densifying Elixir, could provide excellent results for both men and women.

Profollica

Profollica is one of the few hair growth formulas found at Walmart and other major in-store retailers. The formula is also available at Amazon and other major online retail outlets.

Restolin is a perfect blend of natural ingredients, including Vitamin C, Vitamin E, beta-glucan, pine bark, Essiac tea complex, quercetin, and lycopene. Unlike other supplements that flood the body with hair growth support nutrients, Restolin delivers antioxidants that combat free radicals in the scalp and hair cells.

Revifol

Revifol is a dietary supplement that supports hair growth using a supercharged cocktail to help the hair re-grow from follicles. Most supplements on this list mainly focus on hair growth, but Revifol claims to regrow hair in bald spots. Most hair care supplement companies don’t advertise this benefit.

This makes Valotin’s formula similar to Folexin and different hair growth formulas. Additionally, the company is quite transparent about its ingredients.

Our Method of Ranking

While all hair care products claim to support hair growth, most don’t work as expected. To filter the best and worst hair growth supplements, the following metrics were applied.

Clinically proven ingredients

Some hair growth formulas have been clinically certified to work. Such products have been tested on humans and proven to deliver actual, long-term results. For the products on this list, we emphasized formulas and brands that use clinically proven ingredients.

Transparency on advertised benefits

Some manufacturers promise unrealistic benefits of their products. They claim the products can re-grow balding hair and make hair look twenty years younger overnight. Such claims are outrageous and unverified. The products on this list were picked from companies that were honest with their advertised benefits.

Balding reversal

A nutritional supplement won’t reverse balding hair, nor can a hair growth product fix a receding hairline overnight. A good hair growth support formula can only support current hair follicles. However, when a person goes bald, no supplement can regrow hair in that area.

The supplements on this list were taken from manufacturers who were honest about their advertised benefits. For example, enough evidence shows that topical formulas with minoxidil could help lower the balding process.

Cost and Value

While some consumers are comfortable spending just $20 on a hair loss formula, others can spend up to hundreds of dollars to prevent hair loss. This list considered a range of price points to cater to the needs of a diverse consumer base. However, we emphasized good value at every price point.

Real Evidence

Some top-rated growth supplements are supported with factual evidence, such as thousands of user reviews or placebo-controlled clinical trials. Other products are backed by limited information or zero studies with few or no positive reviews. Our ranking considered the amount of factual evidence on each hair growth supplement.

Ingredient Transparency

Some manufacturers promise heaven about their products but fail to reveal their ingredients. Components are essential when comparing hair care products. For instance, some shampoos claim to be natural, yet they contain unnatural components. Some formulas also claim to use the right ingredients but at wrong dosages. In this list, we preferred products with transparent and effective ingredients at correct dosages.

Manufacturer Reputation

While reputable companies such as Beverly Hills or top scientists in certified labs back some hair care products, other manufacturers obtain them from cheap, unregulated factories that use knock-off formulas and weak ingredients. This ranking considered company reputation, with preference to companies with a long and proven record of accomplishment in the hair care supplement industry.

Refund Policy

While they are designed to deliver outstanding results for most people, individual results can vary. This ranking considered supplements from companies that offered money-back or satisfaction guarantees. If a hair care product fails to work, the customer should have a refund. Reliable companies accompany their orders with a moneyback guarantee.

Who Should Take a Hair Growth Formula?

Hair growth formulas and hair care products are made for both men and women. Men use hair growth supplements to fight balding while women take similar products to help them grow thicker and more voluminous hair. The following people should consider taking hair loss supplements:

• Those with hair issues even before taking a supplement
• Those who want to maintain great-looking hair
• Men in their 20s or 30s who are noticing early signs of baldness
• Men who want to restore their younger-looking hair regardless of age
• Any person experiencing a receding hairline or other hair loss issues
• Women who are experiencing thinning hair or some bald spots
• Anyone who would like to fight dullness in their hair and rejuvenate their youthful luster
• Anyone who wants to avoid hair plugs, surgery, prescription medication, or other invasive hair loss remedies
• Any adult person of any age who wants thicker, younger-looking, healthier hair

According to research, 50 percent of men and 25 percent of women will experience hair loss at some point. It’s for this reason that hair loss supplements are becoming popular every day among different age groups.

Hair Growth Supplements: Do They Have Side Effects?

Nutritional hair growth supplements work to deliver natural ingredients that support hair growth without any side effects. So far, the products work well when used by healthy adults at recommended dosages. The users follow the recommended dosage instructions on their hair growth supplements, so they cannot experience any side effects.

By the FDA standards, nutritional supplements must use ingredients and Generally Recognized As Safe (GRAS) dosages. On the same note, topical treatments such as masks, serums, and similar products are not linked to any notable side effects in most users. However, users should be wary of cheap ingredients that could irritate the scalp or deliver an allergic reaction.

For this reason, consumers should shop around first and pick only the best hair care products like the ones on this list. For those with underlying medical conditions or currently under a prescription medication, they should consult their healthcare provider before taking a hair growth formula or product.

Hair Growth Supplement Benefits: What does science say?

While it may sound weird to take a nutritional supplement to combat hair loss, the body requires certain nutrients, proteins, vitamins, and minerals to develop and maintain hair. When the body gets enough supply of these ingredients, it can easily support hair growth.

Importantly, there is some scientific evidence to support the hair growth supplements on this list.

For instance, Biotin is among the most popular ingredients used in hair growth supplements. Some studies reveal that taking biotin daily could help lower the chances of hair loss while promoting hair growth, nail growth, and other benefits.

According to a double-blind, placebo-controlled study conducted on biotin in 2012, researchers discovered that biotin could deliver significant improvements in hair volume, hair thickness, and scalp coverage within 90 days. After 180 days, the participants witnessed more improvements in hair shine, skin smoothness, and moisture retention—all without any harmful side effects.

Similarly, a study conducted in 2017 on biotin revealed that the ingredient could deliver health benefits to hair and nails. Today, many people use biotin supplements to improve hair, skin, and nail health. The B vitamin is widely available in most supplement stores.

Zinc is another widely accepted mineral that supports hair growth. Many people take it daily to combat hair loss. According to some studies, zinc is a cofactor of metalloenzyme, which is why it’s present in any metabolism process in the body. In supporting hair growth, zinc cycles hair follicles as part of hair’s natural growth cycle.

Zinc deficiency is strongly connected to hair loss, with some studies arguing that it’s possible to predict hair loss by just testing zinc plasma levels. In a study conducted in 2020 and published in Diagnostics, researchers discovered a 72.2% correlation between zinc and hair quality. Therefore, a daily dose of zinc could restore hair growth in several ways.

At the same time, some hair care products include copper as one of the ingredients to support hair growth. Unlike zinc that is backed by more scientific research, copper attracts less research. One study reveals that copper and zinc supplementation is particularly effective for those already lacking both minerals.

However, some studies also reveal that copper supplementation could be less effective for a person who already has a balanced diet.

Aside from vitamins and minerals, some hair growth supplements include unique herbal extracts like horsetail extract. This herb is believed to have remarkable effects on the hair. According to some studies, horsetail extract contains high amounts of minerals such as silica, supporting hair growth. Some studies also link this herb to hair growth effects.

Collagen is another widely used ingredient in hair growth formulas. It’s the most plentiful protein in the human body. Many hair growth supplements use collagen to support hair strength, thickness, and volume. So far, this protein has no direct, randomized clinical trials to show that it could significantly support hair growth.

However, some studies link collagen to skin and nail health. The ingredient could support the scalp’s health and support hair growth indirectly.

So far, only two drugs have won the approval of the FDA to treat male pattern baldness—minoxidil (the active component in Rogaine and other hair loss supplements) and finasteride (the active ingredient in Propecia other products). The two drugs are certified to help regrow hair when used accordingly.

For example, the daily application of minoxidil to the scalp could help treat pattern hair loss. Some of the top-rated hair growth products and supplements contain either minoxidil or finasteride. However, these are considered drugs and not nutritional supplements.

Generally, top-rated hair growth formulas and products embrace ingredients certified to work, as shown in several clinical trials. By applying these ingredients to the hair daily, users could support their bodies’ natural hair growth processes.

Top Hair Growth Supplements 2021 Final Word

Hair loss is a common condition worldwide. As noted earlier, about 50 percent of men and 25 percent of women will experience hair loss at some point in life. It’s a sensitive topic for both men and women across the globe, and the hair growth products on this list could help one make an informed decision.

Supplements are good to defend the body against the challenges of hair loss, thinning, and balding. To get genuine products, users should buy from the official websites. To enjoy great results, users can pick any supplement or product on this list.
