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.

What’s In Your Order
One serum. Five compounds. 30 seconds, once a night, before bed. No drug interactions. Stay on your full dose.
The only compound in the formula that gets through the scalp barrier — the reason every other ingredient reaches the tissue underneath instead of washing off in the next shower. Doubles blood flow to the follicles (+121%), feeding the rebuild with oxygen and nutrients the tissue hasn’t seen since you started the medication.
Capixyl rebuilds the grip directly — the same job your scalp’s collagen scaffold used to do before the medication thinned it out. In head-to-head testing it proved 81% more effective than minoxidil. Without the irritation. Without the rebound shedding when you eventually cycle off your medication. That’s why the women in the trial stopped shedding strands their scalp should have been holding.
Every follicle has a command center at its base making one call: hold or release. When the tissue around it breaks down, the command shifts to release — and hair gets evicted years before its time. AnaGain tells the follicle to keep cycling. RootBioTec protects the command center making the call. Together they extend the growth phase by 78% and increase density by 79% — strands per square centimeter, measured by trichoscopy.
Capixyl rebuilds the grip. Vitamin C reinforces the foundation it grips into. Every follicle is anchored into scalp tissue by a network of collagen fibers. On a GLP-1, those fibers fragment faster than they would naturally — the medication accelerates the same breakdown that takes decades on its own. Vitamin C reduced that fragmentation by 44.6% in a placebo-controlled trial. That’s why the protocol works on tissue that’s already broken down.
What Women On GLP-1s Are Saying
- 1Scalp irritation, burning, and itching — reported by up to 38% of users
- 2Unwanted facial hair growth — especially on cheeks, forehead, and upper lip
- 33-month “shedding phase” — increased hair loss for the first 90 days before any regrowth
- 4Dizziness and lightheadedness — from systemic absorption into the bloodstream
- 5Heart palpitations and chest tightness — in women with mild cardiovascular sensitivity
- 6Swelling in hands, feet, or face — fluid retention from vasodilation
- 7Dependency — hair grown on minoxidil falls out when you stop using it

95% Of Women Stopped Shedding In 6 Weeks
The Prevention Serum was evaluated in a peer-reviewed clinical trial conducted by independent dermatologists on women 40 to 65 with aged scalps — the same scalp condition GLP-1 medications create in women fifteen to twenty years younger. Hairs counted by hand. Wash and brush shedding measured 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.

The Journal of Drugs in Dermatology accepted the trial for publication in their June 2026 issue.
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 the medication doesn’t save your hair. It just costs you the weight loss too.
The damage to the scalp tissue is already done by the time you stop. The shedding continues for 12 to 24 months after discontinuation — sometimes longer. And the weight you worked hard to lose comes back inside a year. You lose both.
With hair supplements on a GLP-1, you’re losing the battle before the supplement leaves your stomach.
On 800 to 1,200 calories a day, your body is in nutrient triage. Heart first. Brain first. Liver first. Your hair is the patient sitting in the ER waiting room with a paper cut. He’s never getting seen. Topical delivery is the only way around the triage.

Frequently Asked Questions
A Personal Guarantee From Dr. Kilgour
“Here’s my commitment 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 your brush isn’t almost empty, if the wash-day handful hasn’t disappeared — send back whatever’s left, even empty bottles, and I’ll make sure you get every penny back. No forms to fill out. No questions asked. No ‘proof of use’ screenshots. No hard feelings.
I can offer this because I’ve watched the Prevention Serum work for 150,000+ women — including thousands on every major GLP-1 on the market. Less than 3% have ever asked for their money back. But I’d rather lose a sale than have a woman feel stuck with something that didn’t deliver.
The only real risk here isn’t the serum. It’s another six months of your scalp aging on a compressed timeline while you wait to decide — or worse, quitting the medication and losing the weight loss you’ve worked for, and finding out the shedding doesn’t stop anyway.”
