Best Of The Best Vitamins For Hair Growth: Top 5 Supplements Most Recommended By Experts

Struggling with your hair (or lack of it) and looking for a potential remedy? Signs of baldness like a receding hairline or thinning locks can be frightening and stressful, but there are ways to fight the good fight against your aging body. Millions of consumers turn to specific vitamins and supplements when it comes to maintaining healthy skin and hair, or preventing hair loss. Of course, there’s no easy cure-all, but plenty of individuals find that supplements have made a world of difference when it comes to hair growth or thickness. That led StudyFinds to go looking for the best of the best hair growth vitamins on the market, according to the experts.

Interestingly, research reveals surprising link between the human immune system and hair growth. Researchers suggest that there is some level of communication going on between the immune system’s regulatory T cells a type of white blood cell and a person’s hair follicle stem cells which causes hair to grow. The research shows T cells also have the ability to trigger hair regeneration.

This is further evidence that taking care of your hair is an inside-out job. Properly “feeding” your hair is one way that dermatologists recommend bolstering hair growth. This means adding vitamins into your daily routine. Like Vitamin A, which keeps your scalp moisturized, and vitamin C, which promotes collagen development to grow your hair. 

Another star ingredient that supports hair growth is biotin. Hair loss can be a symptom of biotin deficiency, so supplementation can benefit people with hair loss or thinning hair. According to WebMD, most biotin comes from the foods you eat, but it’s not stored in your body for long. If your diet is experiencing some nutritional gaps and your hair is looking lackluster, it may be time to supplement.

Thicker, longer, stronger, healthier hair in a bottle? That’s the hope, right? So we’ve pinpointed the consensus five best vitamin-based hair growth supplements to help your locks of love shine from the inside out. Thirteen experts rank them by factors, including studies, reviews, ingredients and of course, results. Our list is based on the products that appear most frequently across their reviews. 

The List: Best Hair Growth Vitamins, According To The Pros

1. Nutrafol

According to Prevention, “This uses highly concentrated botanicals to address every stage of the growth cycle, such as vitamin E, ashwagandha (a type of herb), anti-inflammatory biocurcumin, and others. It has excellent clinical studies to support its efficacy. One peer-reviewed study published in the Journal of Drugs in Dermatology, found that women who said their hair was thinning reported improved growth and thickness after six months. The researchers also found an increase in hair density after three months.”

Harper’s BAZAAR says this isn’t just another fish in the sea: “In a sea of powders, gummies, pills, and shots promising thicker and fuller hair, Nutrafol is one of the few hair growth products that actually delivers results. Be patient: results can take three to six months — and you’ll need to keep taking it. It works by fighting off inflammation and free radicals that impair follicle function. Vitamin E, keratin, marine-based collagen, and hyaluronic acid speed up growth, promote absorption of hair-boosting nutrients, and add oomph.” 

Marie Claire consulted a physician who says, “‘Nutrafol supplements target key factors of thinning hair such as nutrition, stress and lifestyle with natural, medical grade ingredients,’ says Dr. Nichols. ‘This clinically effective supplement improves hair growth and visible thickness.’”

2. Hum Nutrition Hair Sweet Hair

Forbes recommends this supplement from Hum: “Hum Nutrition’s Hair Sweet Hair is a line of vegan gummies designed to make hair stronger and healthier, which encourages growth. Dr. Green recommends these gummies since they contain biotin, folic acid, vitamin B12 and zinc to prevent hair loss.” 

“These gummies check off all the boxes: 100 percent natural, 100 percent vegetarian and vegan, GMO-free, gluten-free, and no preservatives. Game-changing ingredients like PABA fight gray hairs and promote natural pigments. While fo-ti (a root used in Chinese medicine) strengthens strands. Plus, you’ll begin seeing results in as little as two months,” Elle writes.

Camille Styles says, “Formulated with hair-loving ingredients like biotin and folic acid, Hum Nutrition’s vegan berry gummies promote longer, stronger, and healthier hair. Along with traditional hair growth supplement ingredients, Hair Sweet Hair also contains Fo-Ti to help combat hair loss.”

3. Viviscal

Men’s Health writes, “This supplement contains ingredients including shark collagen and mollusk powder, both believed to help indigenous Inuits in the Arctic grow especially thick hair. Research published in the Journal of Cosmetic Dermatology suggests that marine collagen can both decrease hair loss and help new hair grow.” 

“Viviscal is a supplement whose hair growth formulation has been clinically supported. It has been designed for men and women dealing with hair loss issues. The makers of this supplement claim that this hair health supplement shows effective results within just 90 days of consumption. The users say they have experienced a reduction in hair loss and an enhancement in density and thickness,” according to Outlook.

Oprah Daily’s consult with a dermatologist led to this recommendation: “‘Hair loss or thinning is multifactorial, meaning there are many different causes,’ says Valerie Callender, MD, a board-certified dermatologist in Glenn Dale, Maryland. ‘The best treatment is one that offers a multi-targeted approach, like Viviscal, which combines zinc, biotin, vitamin C, horsetail extract, as well as a marine complex.’”

  1. Have any of the five formulations been proved to work in peer reviewed randomized, double-blind, placebo-controlled studies? Through the years I’ve found that articles similar to this one entirely overlook that critical question.

  2. What they NEVER MENTION is Hair loss in women is related to hormones. Get a hormone and blood panel to see what hormones you may be deficit in or have too much of. Vitamin D also help Hair growth and helps with hormonal issues.
