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.

KilgourMD was the only scalp serum recognized for outperforming minoxidil in clinical trials with zero side effects.
FSA/HSA EligibleThis serum is FSA and HSA eligible — meaning you can use pre-tax health dollars to pay for it. Most hair growth products on the market can’t clear this bar. They’re classified as cosmetic. To qualify for FSA/HSA, a product has to meet a higher standard — it has to be positioned and classified as a health expense, not a beauty purchase.

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.
You Don’t Have To Stop Your
GLP-1 To Get Your Hair Back.
The weight loss and the hair loss feel like a package deal. They’re not. You can keep the GLP-1 and get the hair back — but only if you treat the right thing, and it’s not the one you’ve been fighting.
What actually grows your hair
At the base of every hair is a tiny engine — the dermal papilla. It sends one thing: the grow signal, the growth-factors that tell the hair to keep building. When the engine runs, hair grows. When it stalls, the follicle rests, and a few weeks later that hair sheds — normally it fires back up and starts over. That’s the whole game. And it’s what a GLP-1 shuts down.
It’s the hormone, not the food
Women lose their hair 14× more than men on the same dose — and lose the weight slower, not faster. So it was never the calories. A GLP-1 holds a hormone on about 5,000× longer than your body ever would, and it starves that grow signal two ways at once: you’re eating less, so fuel gets rationed to your organs and the hair is cut off first; and as the shot lowers your insulin, the IGF-1 signal drops with it. The engine stalls and stays stalled — a wave of follicles resting at once, three to four hundred hairs a day. That’s your handful in the shower, and the part that keeps widening.
That’s why nothing worked
The grow signal is made right at the root, on the spot — and a swallowed pill can’t reach it, least of all when you’re barely eating. Protein feeds your muscle, not your follicle. Biotin and collagen feed the hair, not the signal. Minoxidil only works as long as you use it forever. The only way back is to hand the follicle its signal directly, at the root — which is exactly what a serum on the scalp can do, and a pill never will.
Keep Your GLP-1.
Get Your Hair Back.
It’s not a pill for your body to ration — it’s a serum you put on the scalp, 30 seconds before bed. It hands the follicle its grow signal directly, right where it’s made, without a thing entering your bloodstream to touch your GLP-1. And it does two jobs at once: restart the signal, and hold the hair you’ve still got while it comes back.
AnaGain®Restarts the grow signalThe pea-sprout active. It works right on the papilla, pushing it to send 56% more of the growth-factors that tell a follicle to build — nearly doubling how many follicles are actively growing instead of resting.
RootBioTec®Keeps the signal firingBasil hairy-root extract that keeps the signal-sending papilla cells active — and cuts shedding on its own.
Restarting the signal takes weeks. These hold onto the hair already loosening, so it doesn’t fall before the new growth arrives.
Capixyl®Holds the hair in placeFrom red clover. It rebuilds the collagen bed that anchors each hair in the root — and a well-anchored hair holds its growth phase longer. It gets you more growing hair the opposite way the signal does: not by pushing, but by keeping hairs from ever loosening.
Procapil®Locks the root downGrips each strand deeper into the root, so the loosest hairs stop sliding out before the new growth arrives.
Vitamin CRebuilds the anchorThe face-serum favorite does one quiet thing for hair: it’s the single raw material your body can’t rebuild that collagen anchor without.

95% Of Women Were Shedding Less In 6 Weeks
The Prevention Serum was tested in a peer-reviewed trial run by independent dermatologists, on women losing hair the same way a GLP-1 takes it. 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, drug-free, and has no drug interactions with any GLP-1 medication — unlike minoxidil.
Minoxidil starts with a dread shed — weeks of worse falling before anything improves, because it shocks every follicle out of rest at once. The Prevention Serum does the opposite: less hair on the floor from day one, while the new growth builds underneath.

GLP-1 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 I started my shots. I’d been wanting to lose the weight for years, and it was finally happening. My hair? Thick, full. Didn’t think twice about it.
Then a few months into the GLP-1… 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 honestly thought about quitting the medication over it — but I’d worked so hard for the weight.
I tried a few things — a couple of shampoos everyone swears by, more protein, a supplement my sister sent me. Nothing touched it. I genuinely thought I had to pick: my weight or my hair.
The third photo is me last week. I’ve been using the prevention serum (the scalp one) every night, takes me 30 seconds, and I never came off my medication. 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 you have to choose between your weight loss and your hair — that’s exactly what I thought. You don’t. 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 came from the GLP-1. I blamed myself for years, thought it was my protein, thought I was doing something wrong. It wasn’t. A few months in, 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 thought the only way to stop it was to quit the medication, and I wasn’t willing to give up what it’s done for my health.
Second photo is four months in, still on my meds. 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 Mounjaro last year, loved the weight loss, then the shedding hit and nobody warned me. Grey wad in the brush every wash. Lint roller in three rooms, not kidding.
Figured I had to choose — the meds or my hair. Tried a supplement…, more protein. Nothing.
Second brush is six weeks on the scalp serum. Stayed on my Mounjaro the whole time. Stood at the sink staring at an empty brush like a weirdo.
You don’t have to choose. 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 On GLP-1s Choose Prevention Over The Two Most Common Alternatives
Most women on GLP-1s consider two options when the shedding starts. Quitting the medication. Stockpiling supplements. Here’s how Prevention compares.
Quitting doesn’t save your hair.
The signal is already down — so the shedding keeps going for a year or more after you stop, and the weight you worked for comes back too. You lose both.
On a GLP-1, a pill is the worst way in.
You’re barely eating, so there’s almost nothing for your body to absorb — and what little there is goes to your organs, not your hair. The serum skips all that and goes straight to the scalp.

Frequently Asked Questions
A Personal Guarantee From Dr. Kilgour
“Here’s my promise to you.
You don’t have to choose between your weight loss and your hair. Use the Prevention Serum for 90 days while you stay on your medication. If your shedding hasn’t visibly slowed — if the wash-day handful hasn’t shrunk — one email and you get every penny back. Keep the bottles. No forms, no questions, no proof to send.
I can promise this because I’ve watched it work for tens of thousands of women on GLP-1s. Fewer than 3% ever ask for a refund.
The real risk isn’t the serum. It’s another six months of the signal staying down while you wait — or quitting your medication, losing the progress you fought for, and finding the shedding doesn’t stop anyway.”
