Is the Vegamour Hair Serum Worth It? Look at These Before and Afters (2025)

"Damn, Mary, your hair got so long since I last saw you." That's the first thing my hairstylist said to me when I sat down in his chair two weeks ago. I'll admit that isn't too uncommon for him to say (typically, I get my hair cut once every six months). But this time, it's only been two months since my last appointment. And three bottles of Vegamour Gro Serum later, I needed a trim STAT.

I've never had issues with serious hair loss or hair thinning (I, in fact, am often told I have ~so much~ hair). However, since I've been regularly coloring my whole head copper for the past nine years, my strands aren't nearly as dense as they used to be. In effort to potentially regain some fullness and length, I religiously applied the Vegamour hair-growth serum to my roots for three months to see just how drastically my hair could grow. Did it make a major difference? Keep scrolling.

What is Vegamour?

Vegamour is a vegan haircare brand best known for its hair growth serum that utilizes botanicals—like mung bean and red clover extracts—to minimize shedding and fallout, increase hair's density, and help hair become longer, stronger, and more resilient. Along with the award-winning serum (ahem, it's a Cosmo 2024 Readers' Choice Award winner btw), the brand also creates growth-enhancing shampoos and conditioners, supplements, and lash and brow products too.

How does the Vegamour Gro Serum work?

"This serum combines ingredients like mung bean and red clover to support scalp health and reduce inflammation, creating an optimal environment for hair growth," says dermatologist Pooja Rambhia, MD. "Together these ingredients help block DHT—a hormone that can cause hair loss—stimulate follicles; and strengthen hair for fuller, healthier results," she adds.

Let's break it down, though, because who has ever heard of mung bean or red clover before? I hadn't, and I'm a beauty editor for cryin' out loud. Mung bean is a type of legume native to Asia that is rich in essential nutrients like zinc and silica. "Zinc is critical for hair tissue growth and repair, while silica enhances hair elasticity and reduces breakage," says Dr. Rambhia. As a whole, the extract can help "strengthen your hair shaft and support scalp health."

Red clover, however, "may inhibit DHT production, helping to prevent hair follicle shrinkage," says Dr. Rambhia. "It also has anti-inflammatory properties, creating a healthier scalp environment for hair growth," she notes. The formula also incorporates caffeine to help potentially improve circulation, as well as biotin to help moisturize.

Does Vegamour really help with hair loss?

So here's the thing: The only product that has any research backing to definitively claim that it can help with hair loss is minoxidil (aka the active ingredient in Rogaine). However, moisturizing, soothing products can potentially help encourage hair growth in the long term by creating a healthier scalp environment. So in theory, a product like the Vegamour Gro Serum could possibly lead to some hair growth with consistent, long-term use. And according to thousands of five-star reviews, it has. "I’ve personally found it to decrease hair shedding over time with consistent use—along with dermarolling for increased penetration," says Dr. Rambhia. But she notes, as with anything, consistency is the most important thing here.

My Vegamour experience:

About my hair:

Like I mentioned earlier, I have a ton of hair. I've never experienced significant hair loss, though my hair isn't nearly as thick or long as it was when I was in high school. This is probably due to the fact that I've been coloring it every five weeks for the past nine years, but considering that, it's still extremely healthy and resilient (tysm, bond-building treatments).

I don't typically wear my hair up in tight slicked-back styles because they're ~not my vibe~, and I know that pulling my hair back frequently can contribute to hair loss. Despite regularly wearing my hair down, though, I have noticed minor thinning along my temples which I attribute to my birth control (the struggles of being a girl). This was the target of my entire Vegamour experiment.

How to use the Vegamour Gro Serum:

The serum was super easy to incorporate into my daily routine. The brand recommends using one dropper full per day and to apply it directly to your scalp. I personally found the applicator to be a little small, so I used about three full droppers to dispense the serum along my hairline and my part. Then, I'd massage my scalp with my fingers.

While many growth serums can feel gummy or greasy, this one has a water-like consistency that quickly absorbs into my scalp. I preferred using it on freshly washed hair over dry hair because I found that it absorbed better that way. (Plus, although it didn't make my hair look oily, my roots didn't look quite as fresh when I applied it on dry hair.)

Additionally, though this isn't a requirement, but Dr. Rhambia suggests using a scalp massager tool after application to invigorate the scalp and help the serum reach the roots. Def recommend this just for the overall relaxing vibe.

The Price: A little expensive

One teeny bottle of the Vegamour Gro Serum will run you $64. For something that will last you about a month, that's a decent investment. (Even though I used more than the recommended amount, each bottle lasted me about a month.) I think it's worth it to get the three-pack bundle because you'll get more bang for your buck; plus, the serum requires around 90 days of usage to really start noticing a difference.

My Results:

Three months—and three bottles—in, I've noticed a significant amount of new baby wispies appearing along my hairline and temples. Beyond that, my hair has been growing like weeds. Not only did my hairstylist comment on the major difference in length, but my roots have become more pronounced in a shorter amount of time. Typically, I'll dye my hair every five weeks, but I've been pushing it to four due to how quickly my roots grow out.

Final verdict:

I would confidently recommend this serum to anyone who struggles with hair thinning or wants to boost thickness in an all-natural way. What I appreciate more than anything is how Vegamour utilizes botanical ingredients, rather than medication like minoxidil, to holistically restore hair. Just remember that consistency is key here. It's important to commit to daily application to experience the benefits.

FWIW, this is also Dr. Rambhia's biggest pro for the product too. "The plant-based formula feels lightweight and non-greasy, making it easy to incorporate into a daily routine without my scalp feeling like there is significant build-up," she says. She also notes that it's gentle, even for sensitive scalps.

While it is a bit expensive, opting for a three-pack can save you some money. Though, considering hair is a major source of confidence for so many people (myself included), I find it 100 percent worth it to invest in mine, and that def starts with scalp health.
