Struggling With Sleep? This Rechargeable Sound Machine Is A Total Game-Changer

Have you ever caught yourself staring at your hairbrush and wondering where all your hair went?

Same here. A couple of years ago, I had no issues with my full and bouncy strands. But now, two years after having a baby, it’s looking a little sparse around my hairline. (And the amount of hair I see on my brush or in the shower drain isn’t exactly comforting!)

But as the Journal of American Dermatology tells us, nearly half of women (40%) experience some form of hair loss in their life—so rest assured this is a super common issue. The good news? Everything from thickening shampoos to serums and hair growth supplements can help you get back to fuller, thicker hair. Speaking of hair growth supplements, it can be tough to figure out which ones really work. That’s why I did the digging (and the scrolling through thousands of reviews) to find the ones people truly swear by.

Here are the six hair growth supplements that reviewers love—and the results speak for themselves!

Nutrafol Women’s Hair Growth Supplement ($83.60)

If you’ve ever asked a derm or hair specialist what they recommend for thinning hair, chances are you’ve heard the name “Nutrafol.” With over 18,000 reviews and a solid 4.2-star rating on Amazon—over 40,000 bought Nutrafol on Amazon in the past month alone BTW—this supplement has built a serious fanbase.

Nutrafol targets hair thinning from the inside out, focusing on root causes like stress, hormonal changes, and aging. It’s packed with ingredients like saw palmetto, marine collagen, and ashwagandha (a stress-fighting adaptogen that both your hair and nervous system will thank you for). Reviewers consistently praise Nutrafol; as one person wrote, “Works like magic. Three months after consistently using it, my hair is so much thicker and full of life.”

Viviscal Hair Growth Supplements ($31.81)

Nutrafol may be the dermatologist’s pick, but Viviscal is the one you’ll hear about from stylists and celebs. With over 29,000 reviews and a 4.3-star rating on Amazon, this supplement has earned its spot as a go-to for anyone looking to boost hair thickness and growth, especially if you’ve been dealing with long-term thinning.

What makes Viviscal unique is its clinically-proven marine complex, which nourishes thinning hair and supports existing growth from within. It’s especially popular among people with hair loss related to health issues like anemia or hormonal changes.

One reviewer said, “I’d had a lot of hair loss for at least 10 years due to various health issues, including anemia. Brittle, flaking fingernails, too. In short: my ponytail feels about TWICE as thick as it did 9-10 months ago, when I started taking this supplement.”

Sports Research Biotin with Coconut Oil ($17.95)

If you’re looking for a budget-friendly way to support your strands, you won’t find better than Sports Research Biotin. With over 95,000 reviews and a glowing 4.6-star rating, it’s an Amazon favorite. But the best part might be the fact you can purchase it for under $20.

This no-frills, high-potency biotin supplement works by helping to build the protein for healthy hair and skin. It’s formulated with organic coconut oil to help with absorption.

People rave about it and claim that it gets the job done without breaking the bank. As one reviewer said, “I’m really impressed with this product! The quality exceeded my expectations and it works exactly as described. It’s well-made, easy to use, and definitely worth the price.”

HUM Hair Strong Gummies ($23.39)

Personally, I like my supplements to feel more like a treat than a chore, which is why I was excited to see how much people love HUM’s Hair Strong Gummies. These vegan, berry-flavored gummies are not only fun to take, but they’re also packed with plant-based ingredients that support stronger, thicker hair from the inside out. Think hair-loving ingredients like biotin, zinc, vitamin b 12 and folic acid—everything you need for thick, luscious locks.

With a 4.2-star rating on Amazon, HUM’s Hair Strong Gummies are perfect for anyone who wants results and a little sweetness in their routine.

People are convinced these little gummies work wonders. “After using for one month, areas I watched, I see new growth forming. Good buy reasonable price, good results,” one customer shared.

Vegamour GRO Biotin Gummies ($34.20)

Speaking of clean, plant-based beauty, Vegamour GRO Biotin Gummies are another effective (and fan-favorite) choice. These vegan, berry-flavored gummies are designed to support hair growth, density, and scalp health, all with clinically-backed, botanical ingredients.

They have a 4.1-star rating on Amazon, and more than 2,000 people bought them in the last month alone. If you’re looking for results and don’t want to compromise on clean ingredients or a cruelty-free lifestyle, these gummies are for you!

“I’m on my second order of the 3-pack of these healthy, vegan-friendly biotin gummies,” a reviewer wrote. “They have improved my hair health, reduced shedding, and there is definite noticeable growth too!”

Nature’s Bounty Hair, Skin & Nails Gummies ($7.97)

These little pink gummies are a staples in local drugstores everywhere, and for good reason. With over 19,000 reviews and a glowing 4.6-star rating on Amazon, they’ve earned their spot as a budget-friendly beauty fave (I’m talking under $10!).

Nature’s Bounty Hair, Skin, and Nails Gummies are packed with biotin, plus a blend of vitamins C and E to support collagen production and overall glow. They’re also super tasty, as in, dangerously easy to remember to take. Reviewers rave about noticeable results, especially when it comes to hair growth and strength. One fan gushed, “THIS IS the ticket right here! My personal daily go-to! When people say to me, ‘WOW! Your hair is so healthy, long & thick! What do you use?’ I tell them… Nature’s Bounty’s GUMMY VITAMINS.”

I personally took Nature’s Bounty Gummies a couple years ago and can confirm that they do the trick!

Whichever hair growth supplement fits the bill for you, remember to be patient. Hair grows slowly and that’s totally normal, so give it at least 3 months before judging results. Remember to stay consistent, and pair the supplement of your choice with a healthy diet, so that your body’s getting the nutrients it needs from food, too.

Cheers to fuller ponytails for all of us!
