The Prevention Scalp Serum

Here’s your first response: stop hair thinning before it begins! As your frontline of defense, The Prevention Scalp Serum for hair growth nourishes your follicles, stopping them from shrinking to maintain thick, full-looking hair. By working like a stress repellent for your scalp, it blocks DHT—the hormone that triggers hair thinning—while reducing environmental and aging-related damage. Think of this step like sunscreen for the scalp.

This solution in our serum for scalp health includes a mix of patented ingredients (Procapil®, Capixyl®, Anagain® and RootBioTec®), all representing today’s most advanced plant-based solutions for scalp health, alongside our proprietary blend of liposomal encapsulated L ascorbic acid. When combined with our treatment serum, these active ingredients proved to outperform minoxidil—without the side effects—in a peer-reviewed randomized controlled trial.

Just apply a few drops of our hair thinning prevention serum to your scalp and massage in the product. Repeat this process every night.

We recommend 3-6 months of consistent use to see results.

Lightweight & Easy to Use

Was looking for something to help with my early-stage hair thinning, and this serum is now part of my daily routine. Feels like nothing on my scalp (which is great), and I’ve already noticed less hair in the drain when I shower. No complaints!

Finally, A Scalp Serum That Works!

I've tried everything for my thinning hair—biotin, rosemary oil, even minoxidil (which made my scalp so itchy I had to stop). KilgourMD’s Prevention Scalp Serum is the first thing that has actually made a difference without irritation. My hair looks fuller, and I swear my shedding has decreased. Love that it’s fragrance-free too. I’m on my second bottle and will absolutely keep using it!

Feels Like a Luxury Treatment

This serum is lightweight, non-greasy, and absorbs fast. I use it before bed, and my scalp feels so much healthier. I’ve noticed less shedding in the shower and even some new baby hairs coming in around my hairline. It’s pricey, but considering the quality and results, worth every penny.

Not Sure Yet, But Hopeful

I’ve been using this for about three weeks now. It absorbs nicely and doesn’t leave my scalp feeling greasy. I haven’t noticed any dramatic changes yet, but I’m sticking with it because my scalp definitely feels healthier and less dry. Hoping for some real hair growth in the coming months!

Worth Every Dime

I never leave reviews, but this stuff deserves it. My hairline was receding, and I was desperate to find something before jumping to prescription treatments. Two months in, and I can see baby hairs filling in! It’s slow, but it’s real. Can’t recommend this enough.

Helps With My Dry, Itchy Scalp Too!

Wasn’t expecting this serum to help with my scalp issues, but it totally has. I used to get super dry and flaky around my hairline, and since using this, my scalp feels so much more balanced. It’s also helping my hair look fuller! No strong smell, no irritation—just a really well-made product.

Pretty Impressed So Far

Okay, so I was skeptical about any hair product actually making a difference, but after using this for a couple of months, I do think my hair looks thicker. The application is easy, and it doesn’t leave my hair greasy like other serums I’ve tried. Giving it 4 stars just because I want to see more long-term results before I call it a miracle product.

My Dermatologist Recommended This!

I have super sensitive skin, so I was nervous to try anything on my scalp, but my dermatologist actually recommended this serum. It’s so gentle but effective. I’ve been using it for about six weeks, and my shedding has definitely decreased. My hair even looks shinier. Love that there’s no artificial fragrance—just a clean, science-backed formula.

It’s Actually Helping My Edges Grow Back!

My edges have been thinning from years of braids and tight ponytails. I started using this serum nightly, and after about 8 weeks, I can SEE the difference. Tiny little baby hairs are sprouting up! Super lightweight, non-sticky, and doesn’t weigh my hair down. I’m hooked.

The Best Investment in My Hair

Haircare is self-care, and this serum is proof of that! After two months, my hair feels stronger and thicker. My ponytail has more volume, and even my stylist noticed a difference! This is officially a staple in my routine.
