My Hair Struggles And Why I Chose These Serums?
Let’s get real: my hair hasn’t been the same since my late 20s. Stress, hormonal shifts, and maybe one too many heat-styling sessions left my once-lush locks looking limp and sparse, especially around my temples.
I needed a serum that could tackle thinning while being gentle on my sensitive scalp. After scouring reviews and ingredient lists, Act + Acre and Vegamour stood out. Both brands promise thicker, healthier hair using plant-based, vegan formulas, and they’re backed by clinical studies.
I decided to test them head-to-head (pun intended) to see which one would become my holy grail.
Act + Acre Stem Cell Scalp Serum: The Scalp-First Approach
Act + Acre, founded by trichologist Helen Reavey, is all about treating your scalp like skincare.
Their Stem Cell Scalp Serum uses a cold-processed formula to preserve the potency of ingredients like Swiss apple stem cells, aloe vera, and hyaluronic acid.
The idea is to create a healthy scalp environment to support hair growth, which makes sense—your scalp is the soil, and your hair is the plant.
Pros of Act + Acre
- Scalp-Soothing Superstar: From the first application, I noticed a cooling, calming effect on my itchy scalp. The aloe vera and hyaluronic acid hydrate without clogging pores, which is a game-changer for my sensitive skin.
- Non-Greasy Finish: The serum’s lightweight texture absorbs quickly, leaving no residue. I could apply it post-shower and style my hair without looking like I’d skipped a wash.
- Clean Ingredients: No parabens, sulfates, or silicones. Plus, it’s fragrance-free, which I appreciated since strong scents can irritate my scalp.
- Cost-Effective per Ounce: At $38.64 per ounce (or $30.91 with a subscription), it’s a better value than Vegamour, especially since the 2.2-ounce bottle lasts about two months.
- Clinical Backing: A six-week study showed 90% of users reported a healthier scalp, and I can vouch for that—my scalp felt less tight and flaky after a month.
Cons of Act + Acre
- Slower Visible Results: While my scalp felt amazing, I didn’t notice significant hair growth until about eight weeks in. If you’re after quick density, this might test your patience.
- Pipette Application: The glass bottle’s pipette is precise but can feel tedious if you have thick hair. I sometimes over-applied, which made my roots look slightly greasy.
- No Refill System: The recyclable glass bottle is eco-friendly, but the plastic pipette isn’t, and there’s no refill option, which feels like a missed opportunity for a sustainability-focused brand.
- Pricey Upfront: $86 for a one-time purchase isn’t cheap, though the subscription discount helps.
My Experience With Act + Acre
I started using Act + Acre every other day, applying one pipette to my hairline and part after washing my hair. The serum felt refreshing, like a spa treatment for my scalp. After two weeks, my scalp was noticeably less itchy, and the redness along my hairline calmed down.
By week six, I saw baby hairs sprouting around my temples, which was exciting, but the overall thickness of my hair didn’t change much. The lack of scent was a plus, as I didn’t have to worry about it clashing with my perfume.
However, I occasionally struggled with the pipette, especially when my hands were slippery post-shower.
Vegamour GRO Hair Serum: The Density Dynamo
Vegamour’s GRO Hair Serum is the internet’s darling, with thousands of before-and-after photos showcasing thicker, fuller hair.
It’s packed with phyto-actives like red clover, mung bean, turmeric, and caffeine, designed to block DHT (a hormone linked to hair loss) and boost follicle health.
The brand emphasizes holistic hair wellness, and their clinical studies claim 52% of users saw increased hair density after 150 days.
Pros of Vegamour
- Visible Density Boost: After two months, my hair looked noticeably fuller, especially around my part. My hairstylist even commented on how much healthier my hair seemed.
- Easy Application: The dropper is user-friendly, and the water-like consistency makes it easy to distribute across the scalp. I used two droppers daily, and it absorbed in seconds.
- Pleasant Scent: The light bergamot scent is fresh and uplifting, making the application feel like a little luxury.
- Clinical Results: Studies show 76% of users experienced less shedding, and I noticed fewer strands in my brush after about a month.
- Vegan and Sustainable: Like Act + Acre, it’s vegan and cruelty-free, and the glass bottle is recyclable. Vegamour also partners with fair-trade suppliers, which aligns with my values.
Cons of Vegamour
- Higher Cost per Ounce: At $58 for a 1-ounce bottle, it’s pricier than Act + Acre. The subscription drops it to $44, but it’s still a splurge.
- Potential Drying Effect: The formula contains denatured alcohol, which can be drying for some scalps. I didn’t have issues, but my friend with a flaky scalp found it irritating.
- Small Bottle Size: The 1-ounce bottle only lasts a month, so you’ll need to reorder frequently or buy multiple bottles upfront, which adds up.
- Dropper Design Flaw: The dropper doesn’t reach the bottom third of the bottle, so I had to pour the last bit into my hands, which felt wasteful.
My Experience With Vegamour
I incorporated Vegamour into my nightly routine, applying two droppers to my dry scalp before bed. The bergamot scent was a nice touch, and the serum never left my hair greasy.
After four weeks, I noticed less hair in my shower drain, which was a huge relief. By week eight, my hairline looked denser, and my ponytail felt thicker. However, the small bottle size was a hassle—I ran out mid-month and had to scramble to reorder.
The alcohol in the formula didn’t bother my scalp, but I could see it being a problem for others.
Key Features of Act + Acre Vs. Vegamour Hair Serum Compared
Let’s break down the core differences that might sway your decision.
- Ingredients and Approach
Act + Acre focuses on scalp health with Swiss apple stem cells, which aim to protect follicles and boost collagen production. Aloe vera and hyaluronic acid keep the scalp hydrated, making it ideal for those with dryness or irritation.
Vegamour, on the other hand, targets hair density with DHT-blocking ingredients like red clover and turmeric. Caffeine and mung bean stimulate follicles, which may explain why I saw faster density results with Vegamour.
If scalp sensitivity is your main concern, Act + Acre is the better pick; if you’re after thickness, Vegamour might edge out.
- Application and Texture
Both serums are lightweight and non-greasy, but Vegamour’s water-like texture is slightly easier to spread, especially on dry hair. Act + Acre’s pipette requires more precision, which can be tricky for thick or curly hair.
I found Vegamour’s dropper more intuitive, though its short length was annoying toward the end of the bottle. Act + Acre’s lack of scent is a plus for sensitive noses, while Vegamour’s bergamot adds a spa-like vibe.
- Price and Value
Act + Acre is the better deal at $38.64 per ounce compared to Vegamour’s $58. Subscriptions lower the cost significantly—Act + Acre’s 40% off first order is a steal, while Vegamour’s 15% ongoing discount is less generous.
Act + Acre’s larger bottle (2.2 ounces) also lasts longer, making it more convenient for consistent use. If budget is a factor, Act + Acre wins.
- Clinical Evidence
Both brands boast clinical studies, but Vegamour’s results are more specific to hair growth: 52% increased density and 76% less shedding after 150 days. Act + Acre’s study focuses on scalp health, with 90% of users reporting improvements after six weeks.
My experience aligned with these claims—Act + Acre made my scalp feel amazing, while Vegamour delivered on density.
- Sustainability
Both brands use recyclable glass bottles, but neither offers a refill system, which is disappointing. Vegamour’s fair-trade sourcing and sustainable forestry-certified packaging give it a slight edge, but Act + Acre’s cold-processed manufacturing uses less energy.
It’s a close call, but Vegamour feels a tad more eco-conscious.
Which Serum Wins?
After three months of testing, both serums earned a spot in my routine, but for different reasons.
Act + Acre is my go-to for scalp health—its soothing formula transformed my itchy, flaky scalp, and the baby hairs were a nice bonus.
Vegamour, however, stole the show for visible results. My hair looked thicker and fuller faster, and the shedding reduction was undeniable.
If I had to choose one, Vegamour would be my pick for its density-boosting power, but Act + Acre is a close second for sensitive scalps.
Your choice depends on your priorities. If you’re battling irritation or dryness, Act + Acre’s gentle formula is a safe bet. If you want quicker results for thinning hair, Vegamour’s phyto-actives deliver.
Either way, consistency is key—stick with your chosen serum for at least 90 days to see real change.
Frequently Asked Questions (FAQ)
Minoxidil-based serums like Rogaine are the only FDA-approved option for hair regrowth, but Vegamour GRO Hair Serum worked best for me, boosting density and reducing shedding after three months.
Vegamour doesn’t regrow hair in the same way minoxidil does, but it reduces shedding and increases density, making hair appear fuller. I saw noticeable thickness after two months.
There’s no confirmed evidence that Nicole Kidman uses Vegamour. Celebrity endorsements are often rumored, but I couldn’t find credible sources linking her to the brand.
Nulastin uses elastin-supporting proteins to strengthen hair follicles, while Vegamour relies on plant-based phyto-actives like red clover to block DHT. Nulastin is pricier, and Vegamour feels lighter on the scalp.

You’ve got two stellar options in Act + Acre and Vegamour, and I hope my journey helps you pick the right one. Act + Acre is your scalp’s best friend, soothing irritation and laying the groundwork for growth.
