If you’re noticing hair shedding, thinning strands or abnormal hair loss, the first step is to call a board-certified dermatologist to rule out any serious health issues. After that, know that you’re not alone. Hair loss can be triggered by a variety of factors such as hormonal swings, stress and medications or even harsh hairstyles and products. I’ve got good news though: there’s no shortage of over-the-counter treatments and supplements that are expert-approved and backed by rigorous clinical testing (in some cases for decades) to help, and many of them are conveniently available on Amazon.
We researched which hair growth products on Amazon are getting the best ratings and reviews by real users. Ahead, the ones that have impressed them the most and why.

“I committed to the full three-month, 180-tablet supply of Viviscal Hair Growth Supplements for Women and followed the directions—one tablet in the morning, one at night. By week four, my shower shed diminished noticeably; by week eight, I could see soft ‘baby hairs’ sprouting along my hairline. Now, at the 12-week mark, my ponytail feels denser and my scalp is no longer peeking through in photos.”

“I have thin, fine hair and have had issues in the past with hair products weighing down my hair. I have been using this product over two years now and have noticed fewer strands falling out, new growth and my hair seems to have more bounce.”

“This has really worked with encouraging hair growth and reducing shedding. I use it with my rubber massager before bed…and when I wake up I’m always surprised my hair is not greasy…just soft. Lots of baby hairs popping up (also taking vitamins for hair) and my hairdresser even noticed all the new growth.”

“Forty one-year-old mom here, I was losing hair so fast and pulling out handfuls from my hairbrush. Nioxin has been around a long time and has a great reputation. It did not disappoint. Both my husband and I use it daily. It gives your hair a squeaky clean feel, and within one week of use, I noticed less shedding. I am also seeing tiny hairs on my scalp where it is creating new growth. We will definitely reorder! It has a light minty smell, and we have seen a huge improvement in our hair loss.”

“I can’t tell you how happy I am with my results so far and I have not finished the bottle yet…and the results are insane!… In [my] after picture my hairline has filled in significantly and I can see all the new little hairs coming in that weren’t there before.”

“I started seeing less hair fall in the shower within the first two weeks, and by the six-week mark, I noticed some baby hairs coming in along my hairline. My hair feels thicker, healthier and has more shine. I also love that the formula includes biotin, collagen, keratin and other hair-boosting ingredients in one daily supplement—it’s convenient and doesn’t upset my stomach.”

“This oil is the truth! I’ve been using it consistently on my scalp and edges, and the growth is definitely showing. It’s a little thick, so I use just a few drops and massage it in, a little goes a long way. It also helped with dryness and made my hair softer and fuller. The smell is strong but not unbearable, and the results make it 100% worth it. Don’t sleep on this one!”

“100% these work. Trust me. After having a child, my hair was never the same again. The constant shedding, the irritated scalp—it was depressing. So I gave in and I can honestly tell you after using the supplements for a year, the shedding is minimal, but my hair is back to being full and there’s constant new growth coming in. I no longer have an itchy irritated scalp. Also, it makes your nails grow so who doesn’t want that?”

“I was losing a lot of hair, and it was starting to look super thin, dull, and kind of fried…I’ve been using both the shampoo and conditioner for a little over a month now, and I definitely recommend getting both… Since I started, I’ve noticed a big difference. My hair looks shinier, feels stronger, and the thinning at my temples is barely noticeable now. I’m even seeing some baby hairs coming in.”

“I’ve been using Nutrafol Women’s Balance for a few weeks now, and I’m genuinely impressed. As someone 45+ who’s been navigating hormonal changes, I’ve tried various supplements with little to no results until now. After consistent daily use, I’ve noticed visible new hair growth along my hairline and crown, especially in areas that had started thinning. My scalp feels healthier, and even my stylist noticed more fullness.”
