It’s a natural temptation to cave into the allure of super-long length to frame our favorite looks. The one and only hitch? The ever-so-slightly important process of actually getting that ultra-long length. For many of us, growing out our strands can seem impossible—what with annoying factors like split ends, abuse from our favorite styling tools, scalp buildup, genetics, and basically anything else that poses a vendetta against all of our long hair goals. Luckily, however, there are some effective solutions to help remedy the situation. Getting regular trims and regularly treating your hair to some hard-earned TLC goes a long way, but sometimes some extra help from hair growth–promoting products and supplements can do the trick do. We’ve heard from countless readers and fellow co-workers that Amazon has an impressive secret stash of products for hair growth, so we decided to dig around and comb through reviews to find out which of said products Amazon reviewers love most. So in the name of longer, stronger hair this season, keep reading for 14 of the best products for hair growth, according to the nitpicky standards of Amazon’s toughest beauty-shopping critics.

Collagen supplements have been making waves in the wellness world for a while now, and according to nutritionists, they can play a role in hair and skin health. Due to collagen’s rising popularity, there are tons of formulas on the market, but this powder from Sports Research is the unanimous Amazon fave. “My hair is growing insanely fast. How do I know this? Because I touch up my roots to cover grays, which I needed to do every four weeks (exactly) and now have to do it between two and three weeks. That is INSANE. There is also much more new hair that is now very noticeable,” explained one happy reviewer named Gavilan.

Despite the fact we have an initial eye-roll reaction when it comes to gummy supplements, according to the overwhelming surplus of positive Amazon reviews, these are one of the best products you can get your hands on for hair growth. They’re vegan, cruelty-free, and strategically formulated with essential nutrients starved strands crave like biotin, folic acid, and vitamin D. “My hair was falling out in clumps and getting super thin in the front,” explained one reviewer Cyferguson. On the recommendation of my hairstylist, I ordered these gummies and now have tons of new hair growth. I’m so pleased, and they taste amazing. I have trouble limiting myself to the recommended dose!”

Almost every dermatologist I’ve ever chatted with about hair health has told me that scalp massage is one of the best things you can do to stimulate hair follicles for increased growth.

Number of customer reviews: 9183. Average rating: 4.5/5. Biotin and coconut oil are two of the most infamous ingredients when it comes to hair health. Thus, when the two come together in this epic hair growth product from Sports Research, it came as no surprise the results (and reviews!) are impressive. “I started to see a difference in as little as 2 weeks!” exclaims Antoinette Castillo on Amazon. “My hair was no longer falling out as much in the shower, and I began to see baby hairs growing in where my hair was thinning. I’m glad to have found a product that actually works. Even other people are noticing that my hair is growing back which definitely gives me a confidence boost.”
Number of customer reviews: 3923. Average rating: 4.5/5. Many experts we’ve talked to recommend castor oil to aid lash and eyebrow growth, but word on Amazon is that the special oil can also work hair growth wonders on top of the scalp. (We also love that this formula is USDA-certified organic and cold-pressed!) “I am now a fan of castor oil!” one Amazon reviewer practically shouts. “I’ve always read that castor oil was great for hair growth, so I decided to give it a try. I’ve been using it on my eyebrows, lashes, and on my hair (my hair is natural, veryyyyy curly and colored), and in a month I can already tell a difference. My eyebrows seem much thicker, my hair is so soft, thick, and healthy. My lashes are looking thicker and longer. I also use this on my skin.”

Thanks to the team of hair experts at Hairfluence, this well-reviewed hair growth product contains not only superstar ingredient biotin but also a complete synergistic blend boasting a variety of essential vitamins, minerals, and amino acids that work together to ensure faster-growing and healthier hair. “I finished my first bottle, and I’m ordering another one!” satisfied reviewer KristinaM confesses. “The most noticeable effect I noticed during the first month is not the hair growth but the reduction of hair loss. I lose about half the hair I used to lose in the shower since taking Hairfluence.”
Number of customer reviews: 4614. Average rating: 4.5/5. If you’re not into poppable supplements, a high-quality shampoo or topical formula can also do the trick. This one is maximum strength and contains TLC-gifting ingredients like biotin, provitamin B5, zinc, coconut oil, and other hair-healthy botanicals. “Love this! I have thinning hair due to genetics and bariatric surgery; huge amount of hair fall. Since using this shampoo, the hair fall has significantly decreased and I can feel stubblies (is that a word?) on top of my head,” a reviewer named Carol says.
Number of customer reviews: 1742. Average rating: 4/5. Combining pivotal ingredients like a whopping 5000 MCG of biotin in addition to helpful side hustlers like vitamin C and other B vitamins, these coated caplets from Nature’s Bounty are a slam dunk for expedited hair growth. “I have Systemic Lupus Erythematosus,” one Amazon reviewer disclosed. “Because of this disease, I have some hair loss, plus, thanks to all the biologic drugs I have to take, I had massive bald spots. My hair was falling out in the handfuls, so I was referred by a friend to take these vitamins. I started taking them and within 2 months had lots of new growth in my bald spots. I have continued to take the vitamins and my hair is full and beautiful.”
Number of customer reviews: 1849. Average rating: 4.5/5. According to the experts at Propidren, one of the main factors in terms of hair loss is the production of dihydrotestosterone or DHT (and our research backed this up!). Thus, the brand set out to launch a product containing clinically proven DHT blockers that synergistically stop hair loss while encouraging regrowth and enhanced hair thickness. “I am a breast cancer survivor in remission. I am thrilled to add this to my regimen for the regrowth of my hair. THANK YOU SO MUCH FOR THIS WORKING FORMULA! Glad to see my results,” says Amazon reviewer Crystal Ly.
Number of customer reviews: 579. Average rating: 4.5/5. Any product that reads “hair fertilizer” immediately piques our interest. Ideal for African American hair types, this deep conditioner is meant to heal hair that’s been damaged due to braiding, heat, and chemicals. Essentially, it utilizes key power players like proteins, vitamins, olive oil, shea butter, and oils from peppermint and sweet almond to treat and restore weak and brittle strands. Just look at the below happy review for proof. “100% works!! Warning, it does feel like an Icy-Hot on your scalp. The first time it was kind of a shock, but it hasn’t bothered me since, and it has definitely helped my hair grow double what it normally would. I usually use it every other day, and I’ll leave it on for about five minutes in the shower. It has definitely helped to heal the damage in my hair.”
Number of customer reviews: 351. Average rating: 4.5/5. With all-natural and pure ingredients, this is one of the most beloved growth-promoting hair products on Amazon’s market. The formula includes castor oil, caffeine, rosemary oil, and biotin to infuse both scalp and strands with essential omega-6 fatty acids, minerals, proteins, and vitamin E. “I have been wearing my hair natural for a year now,” confides reviewer Erin Graham on Amazon. “I trust Aroamas products, but when I find something that is exceptional, I have to rave about it. I started using this oil about three weeks ago. Since then, I have been religiously using it every night. I can tell the difference in the health of my scalp. It feels nourished and healthy and it is evidenced in the rapid growth of my hair. This is a definite keeper in my arsenal of products for natural hair.”
Whenever someone asks me about hair growth supplements, these tablets from Viviscal are the first to pop out of my mouth. I’ve talked to scores of hairstylists who recommend them (and whose A-list clients use them on the reg), and they helped rehab my hair after I struggled with an eating disorder in high school.
I love and swear by countless products from Hum Nutrition (specifically Flatter Me, $25 and Beauty Zzzz, $10), but these hair-boosting gummies are by far my fave, and I swear on my life to anyone who will listen that they’ve completely transformed my hair in the past year since I’ve started taking them. They taste great (but I recommend eating them with food because they contain zinc), and my hair has never looked so thick or grown so fast.
