The experts consulted for this story do not necessarily endorse the products ahead unless otherwise noted.The hair loss statistics have floated around long enough for many of us to learn by experience how real they are: The older we get, the higher our chances of losing some if not all, of our hair. Although men are prone to it happening earlier and more often, women aren’t immune to hair loss, either. It’s often just wishful thinking to believe that something as simple as an affordable shampoo can get to the root of all your hair-thinning woes. However, this unassuming bottle from Amazon has so many of us thinking some real mitigation might be possible. Enough reviewers vouch for its ability to slow down excessive shedding and help noticeably thicken hair overall that we had to dig into it.Per the reviews, that scary is-this-normal-or-is-this-balding shed experience is no match for this cleanser.“I have mid-50s thinning, perimenopausal, easily falling out hair,” one shopper shared.“I used the shampoo as directed, leaving it on for about 3 minutes while washing the rest of me and then washing it out. Within just a few washes, I noticed a difference in my hair falling out.”Made by indie hair care brand Maple Holisitics, this biotin-infused shampoo promises to harness the power of all-natural ingredients to make fine or thin hair appear thicker and more nourished and the scalp more hydrated —and reviewers’ testimonies appear to support these claims.Even from the first wash, users of the Maple Holistics formula claim their fine hair looks and feels instantly thicker, more volumized and healthier, without having to add extra steps or products into their existing routine.With extended use, some share that they’ve noticed a significant reduction in the amount of hair that falls out during washing, quicker hair growth. In some cases, even new hair growth in areas around the hairline where there was previous sparseness.While one reviewer calls it a “miracle shampoo” for thinning, it’s actually not a special phenomenon. Regrowth is often possible — and we’ve previously asked a dermatologist for the science behind how it can really happen.Given what we’ve previously gathered from dermatologists and trichologists, some studies show that many of the active ingredients used in this sulfate-free and color-safe shampoo have been proven to support healthier and better hair growth — particularly rosemary oil.Dr. Marisa Garshick, a board-certified dermatologist with MDCS Dermatology in New York City, previously said that rosemary oil not only conditions and strengthens hair, but also helps reduce damage and breakage, thereby contributing to a stronger hair appearance.“Research has also indicated that rosemary oil can potentially accelerate hair growth by improving blood circulation in the scalp, which stimulates hair follicles,” Garshick added.Now, there’s not enough substantial evidence to support that biotin plays a meaningful role in promoting hair growth (beyond what’s made anecdotally), Garshick said that ingredients like evening primrose oil and jojoba (which this formula contains) can address dryness and brittle-feeling hair.Another thoughtful inclusion is naturally antifungal tea tree oil, which can help suppress dandruff and other scalp conditions caused by fungi or bacteria. (According to some studies, the health and condition of the scalp can affect hair growth and retention.) Additionally, vitamin E may offer antioxidant benefits for healthier hair and scalp and argan oil, which is also rich in fatty acids and antioxidants, can add shine and moisture to strands and scalp. Using this shampoo is easy-peasy, according to the brand and reviewers who own it.Lightly and naturally fragranced like sandalwood, reviewers suggest letting the lathered shampoo sit on the hair and scalp for two minutes before washing out, per the brand’s directions. That’s it. Nice and simple like a wash session should be, no?Additionally, many also like this shampoo so much that they’ve also begun pairing it with Maple Holistic’s matching conditioner, which can be purchased separately or as part of a set.

Promising Amazon reviews:“Do you want to know what it feels like to have a thousand tiny fairies with cold hands give you a head massage? If yes, then buy this. It’s a magical experience every time I wash my hair. And be sure to scrub it into the scalp and let it sit there for a couple minutes. Doesn’t disappoint! I’ve only been using it a few weeks, but my hair already feels stronger and thicker. One of the most gratifying things I ever bought. 100/10” — BJoyR“I’ve been using this for about a month and change, but I wanted to wait until it had been a while to get good results and give an accurate review.For reference, I have mid-50s thinning, perimenopausal, easily falling out hair.I used the shampoo as directed, leaving it on for about 3 minutes while washing the rest of me and then washing it out. Within just a few washes, I noticed a difference in my hair falling out. It didn’t stop it, but it certainly helped slow it down. The thickness of my hair is also noticeably better and it doesn’t fall flat to my head like it used to.My hair after washing is always very soft and shiny and it doesn’t leave my scalp dry or my hair brittle. I have the Peppermint scent, which I highly recommend, and it smells fantastic without being overpowering.Overall, I am very pleased with this shampoo, as it does everything that I wanted it to do. Clean my hair, help with thinning and hair loss and also leave bouncy happy hair.” — Amazon Critter“Definitely a notiecable difference! I’ve only used this a few times now so there’s no way it’s causing any actual new hair growth, but there is a huge and noticeable difference when using the shampoo. I haven’t changed any of my styling products or even conditioner. Just switched out my shampoo. I wash and let sit for two min like suggested. I don’t know what magic is in it but my hair definitely feels and looks fuller. My hair has been thinning due to health issues and none of that has changed. I started buying wigs because I was self conscious and feeling defeated every time I styled my hair because of the thinning. If it actually helps hair growth I’ll never use another shampoo again. I’ll have to report back later to see if I’ve noticed anything else as I finish the bottle.” — nk“I don’t usually write reviews, but I’m so happy with the results of this shampoo that I had to share. I’m a 29 M and about a 2 years ago, I started noticing an unusual amount of hair falling out while showering. Honestly, it really scared me. As the months went by, the hair loss seemed to get worse, to the point where I dreaded washing my hair for fear of seeing handfuls come out.I didn’t want to resort to medication, so I tried another hair-thinning shampoo, but it didn’t make much of a difference. My hair became visibly thinner, and when I styled it, I would fail the flashlight test. That’s when I decided to switch to this shampoo, and I’m so glad I did.Within three months, I noticed a significant improvement. The amount of hair falling out in the shower slowly decreased and now I’m down nt to just just 2-5 strands. I really didn’t notice at first but now when I look at my hair, I can see it’s physically thicker. I’ve also noticed a ton of baby hairs growing along my hairline, and my thinning corners are starting to fill in.It hasn’t been that long since I started using this shampoo, but I’m genuinely thrilled with the results so far. If you’re considering buying this product, I highly recommend it.” — Brandon & Molly Czworniak
