Nothing in the Prevention Serum comes from animals, and nothing, not the serum or any single ingredient, is ever tested on them.
It’s safe around them, too. Minoxidil is toxic to cats — and not just if they lick the bottle. Residue on your hands, your pillowcase, the towel you used — a cat that curls up where you slept and grooms itself can get enough to make it seriously ill, sometimes fatally. The Prevention Serum carries none of that risk. You can keep it on the counter and never worry about your cat or dog.
Beauty and wellness should never come at a cost — to you, or to the animals you love.

Marie Claire 2024 — Best Medical-Grade Scalp Solution
Winner of Marie Claire’s annual Beauty Awards — judged by editors and dermatologists. The “medical-grade” category specifically recognizes products with clinical backing.
Elite Lifestyle Magazine — Best Scalp Care Serums, 2024Winner of the 2024 ELITE Beauty Award for Best Scalp Care Serums in the Scalp Care & Hair Growth category.

Apply one dropperful to your scalp before bed. Part your hair in 2–3 sections and apply directly to the scalp — not your hair. Massage for 30 seconds. That’s it.
Your scalp repairs itself during sleep. Blood flow increases, cell regeneration peaks. The serum works with that cycle overnight.
150,000+ Active UsersWhat’s In Your Order
One serum. 30 seconds before bed. No prescription, no hormones, no side effects.
After menopause the blood flow your scalp runs on drops off, and starved of it the scalp ages fast and the grip on each hair gives out. Procapil reopens that blood flow and rebuilds the grip, so your scalp gets younger and starts holding onto hair again.
A young scalp grips each hair tight. An aged one lets go — and that’s the strands you keep finding in the brush and the drain. Capixyl rebuilds that grip directly, the job your scalp’s collagen used to do before menopause wore it down.
On an aged scalp, follicles quit early and push hair out before its time. These two switch them back on — holding each follicle in its growth phase longer and waking the sleeping ones up, so the part fills in.
Every hair is anchored into your scalp by collagen. After menopause that collagen breaks down faster — years of aging speeding up. Vitamin C is what your body rebuilds collagen with, so the foundation each hair grips into gets strong again.
How KilgourMD Was Made
It started with three things almost nobody knew about hair loss — and one doctor who couldn’t stop thinking about them after his own mom started losing hers.
After menopause, your scalp ages faster than any skin on your body.
Researchers in France measured two patches of skin on the same women — the forehead and the scalp, right down where the hair is rooted. After menopause, the forehead held up. The scalp aged years faster — up to ten times faster than the skin on your face.
You can’t see it, because it’s happening below the surface. But underneath, the grip on every hair is letting go. That’s the real reason your hair is thinning — not the hair itself, the scalp it grows from.
The hair was never the problem. The scalp was.
This is the part that should give you hope. Researchers at PNAS — where Nobel-level science gets published — took healthy follicles and placed them in aged scalp tissue. They died.
The follicles were fine. It was the ground they were sitting in that had given out. Think of a seed and the soil — the best seed in the world grows nothing in dead ground. Your follicles aren’t gone. The scalp around them just aged too fast to hold them — and that’s the part you can fix.

He built it after watching his own mother lose her hair.
Dr. James Kilgour didn’t set out to build a hair brand. He built it for his mom.
He watched her hair thin through menopause and watched her try everything — nothing worked. So he made her something himself. He’s a dermatologist, and instead of treating her hair, he treated her scalp. Slowly, it came back — and he watched her come back with it, more like herself than she’d been in years.
Everything he learned bringing his mom’s hair back went into this. What started as one routine for one woman has now helped over 150,000.

95% Of Women Stopped Shedding In 6 Weeks
The Prevention Serum was tested in a peer-reviewed trial run by independent dermatologists, on women whose scalps had aged years past their real age — exactly what menopause does to your scalp. Every hair was counted by hand, in the shower and in the brush, before and after. Here’s what they found.
Tap each result to see the proofClick each result to see the proof →
A 68% reduction in wash-day shedding — measured in a clinical sink, two consecutive washes, every released strand counted by hand. Not estimated. Not self-reported. Counted.
A 60% reduction in brush shedding — each woman seated in a hairdresser’s chair draped in weft fabric, three combs run through her hair in a fixed sequence, every strand caught and counted by hand.
Zero women reported side effects. Zero dropouts. The Prevention Serum is non-hormonal and drug-free — it can’t make your hair worse, only better. Unlike minoxidil.

Hair Recovery Stories From Our Customers ❤️
Okay I don’t normally do this but I have to share because I know so many of you are going through the exact same thing. That first photo is me and my husband in Paris a few years back — right before everything changed. My periods had just stopped for good, so I was officially in menopause, and I had NO idea what was coming for my hair. Look at it. Thick, full, didn’t think twice about it.
Then about a year into menopause… it started. The second photo is what I’d pull out of my hair in the shower — every single wash, a handful like that. And the worst part was the top of my head, you can see in the photo how you could see right through to my scalp at the part. I stopped parting it in the middle. I started wearing it up so people wouldn’t notice from above. I cried in the car more than once.
I tried a few things — a couple of shampoos everyone swears by, a supplement my sister sent me. Nothing touched it. I genuinely thought this was just my life now.
The third photo is me last week. I’ve been using the prevention serum (the scalp one) every night, takes me 30 seconds. The shedding stopped first — that was the thing that made me cry happy tears, not finding it all over the shower anymore. And then it just slowly came back. My part filled in. It feels like MY hair again.
I’m 57. If you’re sitting there thinking it’s too late or it’s just menopause and nothing can be done — that’s exactly what I thought. Please don’t wait as long as I did. 💛
I debated sharing the “before” for a long time — it’s hard for me to look at. But if it stops one woman from waiting the way I did, fine.
Mine started in menopause. For the longest time I blamed myself — thought it was something I was doing wrong, something I wasn’t eating. It wasn’t. My temples… started receding — the kind of thing you catch in a shop window and don’t recognize. I stopped wearing my hair back. For two years.
Biotin, collagen, two shampoos that promised everything. I’d more or less accepted that this was just what I looked like now.
Second photo is four months on the serum. The temples are filling back. Not all the way — I won’t pretend — but it’s coming back. I can pull my hair off my face again.
That’s my hairbrush. Both photos, same brush. Started about two years after menopause — the shedding hit and nobody warned me how bad it’d get. Grey wad in the brush every wash. Lint roller in three rooms, not kidding.
Figured this was just my age and I’d be cleaning hair off everything forever. Tried a supplement…. Nothing.
Second brush is six weeks on the scalp serum. Barely anything in it now. Stood at the sink staring at an empty brush like a weirdo.
It’s not just your age. That’s it. That’s the post.
Visible Results In 90 Days Or Your Money Back
Use the Prevention Serum every night for 90 days. Don’t see less shedding and a fuller ponytail? You get every dollar back. Less than 3% of our customers ever claim it.
Why Women Choose Prevention Over The Two Most Common Alternatives
Most women try two things when menopausal shedding starts. Minoxidil. Stockpiling supplements. Here’s how Prevention compares.
Minoxidil forces an aged scalp instead of fixing it.
Minoxidil forces an aged scalp instead of fixing it — and most women over 40 don’t even respond to it. The day you stop, the hair it grew falls out. Prevention repairs the scalp so the hair stays on its own.
A pill can’t reach the one place that matters.
A pill can’t reach the one place that matters. The shedding starts in your scalp, and that’s where this goes — straight to it, no detour through your gut.
