No two hair journeys are equal and therefore shouldn’t be treated with the same energy. Finding quick and easy solutions to our “problems” is also easy in theory but can be hard to pin down. I, like so many others, often feel hesitant when selecting a supplement to support my health. With so many products available claiming to address even the most niche of my concerns, the process can extend far beyond my limited medical expertise.

To better understand what I’m up against in the battle to maintain hair health, I reached out to New York–based board-certified dermatologists Marisa Garshick, MD, FAAD, and Jessie Cheung, MD, FAAD. First up: the question of which vitamins are the most effective to jump-starting hair growth. Ready to learn everything you need to know about hair supplements? Keep reading!

“It is known that a deficiency in certain vitamins such as iron, vitamin D, zinc, and B12 may contribute to hair loss in which case it can be important to supplement,” Garshick says. “There are other supplements available that use a combination of different ingredients which can be considered as well such as Nutrafol, Vivascal or Welbel.” While most supplements are considered safe to take, Garshick recommends speaking with your medical provider to determine what would serve you best.

Feeling like biotin is the best option? The popular vitamin, along with a number of other micronutrients found in the most effective supplements for hair growth. Biotin taken alone, however, has limited evidence. Both Garshick and Cheung cited a 2016 study released by the FDA warning that biotin may interfere with certain laboratory tests including thyroid and troponin levels. That being said, it’s always best to indicate all medications and supplements when visiting your doctor.

Cheung agrees with Garshick, recommending patients to request their labs be drawn before adding any supplement to your diet. Of all the vitamins heavily touted for supporting hair growth, bioton is by far the most recognizable. “Biotin, which is one of the B vitamins, helps with hair strength,” she begins. “The most effective micronutrients are iron, zinc, vitamin D, vitamin B, selenium, iodine, and antioxidant and adaptogen blends.” Higher quality supplements will be free of fillers, binders, and contain more bi-active and easier-absorbed formulations.

Below are the 10 best hair supplements based on dermatologist recommendations and thousands of glowing customer reviews to simplify your hunt for the most effective hair growth aid. Here’s to a new chapter in your hair journey (and a whole lot of money saved).

“Nutrafol is a supplement to help support hair growth as it contains the Synergen complex which includes a combination of anti-stress adaptogens, antioxidants, anti-inflammatory and DHT blocking ingredients,” Dr. Garshick says. The end result? Studies show that 86% of women noticed improved hair growth, 84% noticed stronger thicker hair and 75% noticed reduced shedding after use. “I have taken this product for almost a year now and I cannot recommended it enough. Anyone that has experienced hair loss due to stress or COVID needs this supplement to give your body what it needs to support more hair growth!” — Sephora customer

Created with over 60 years Trichological expertise, Philip Kingsley’s Tircho Complex Vitamin & Mineral Hair Supplement supports the hair growth cycle with daily use over 12 weeks. I love how it can also be used in combination with the rest of the brand’s effective Trichotherapy line. “I have been taking Tricho Complex for over three months now, and I can really tell the difference: less hair in the drain while washing and less fall out during brushing and through out the day. Great value for the price! Would def recommend as a daily support for those with weaker hair.” — Neiman Marcus customer

Can’t wait to see the results in a couple months!” — Sephora Customer

It is the real thing—myhair is growing back in places that I thought was destroyed at the root and would never regrow again. I am a supplement junkie and have tried many hair growth products. Nothing has worked except for Phtyo (and it it does not take long to work). I am thrilled and would highly recommend it to anyone.” — Amazon customer
