Most women treat their hair. Smart women treat their scalp age. KilgourMD is the only protocol I recommend for it.

18 years ahead of your age of 55
Scalp age is a measure of follicular capacity — how much of your hair the scalp can hold in growth, how reliably it restarts growth after a shed, and how thick a strand it can still build. Yours is showing its age in all three.
Marker 1Shedding Phase
More shedding
The extra shedding you’re noticing? That’s your scalp age pushing hair out of anagen — the growth phase — and into telogen, the shedding phase, too early.
Studies show a young scalp keeps about 9 in 10 hairs in anagen at once; an aged scalp drops to 3 to 5 in 10.

Marker 2Empty Follicles
Less regrowth
The reason your part is where it shows most: an aged scalp stops keeping up with what it sheds. A hair falls out, and instead of a new one starting behind it, the follicle just sits there empty.
Studies found up to a third of follicles sitting empty like this for months at a time — dermatologists call them kenogen, and a landmark paper named them the main cause of thinning.

Marker 3Thick vs Fine Hair
Less thickness
And the hair that does grow back comes in finer: an aged scalp builds thin strands where it once built thick ones.
Studies show the ratio drops from about 13 thick hairs for every fine one down toward 2 to 1.

top responders
Your answers match the women who participated in the peer-reviewed trial behind KilgourMD — published in the Journal of Drugs in Dermatology. It followed menopausal women with similar hair loss you just described.
Matching these criteria does not predict your result. Individual results vary and are not guaranteed.
Tested by DermaclaimFirst, your scalp starts
holding on to more hair
Anagain™
Hair Cycle ActiveThe first job of a young scalp is holding hair in growth. As it ages, that grip fails — the signal telling a follicle to keep growing fades, the signal telling it to stop takes over, and more hair gets pushed out of growing and into shedding.
AnaGain works on both sides of that. It turns the growing signal back up and quiets the one telling follicles to stop. In its own clinical studies, it nearly doubled the number of hairs in the growing phase.
Procapil™
Anti-Shedding PeptideWhile AnaGain resets the cycle, Procapil works on grip. It reinforces the anchoring proteins at the base of the follicle, so healthy strands stop letting go before their time. In its studies, it cut hair fall by up to 46%.
Individual results vary. Not all users will experience these results.
How shedding was measured
In the KilgourMD trial, shedding wasn’t self-reported — it was counted. Women collected the hairs shed during a standardized wash, and an independent lab counted them by hand, at the start and again at week six.
The 68% figure is the drop in that wash count. No estimates, no surveys — just fewer hairs, counted.

Tested by DermaclaimThen the empty follicles
start making hair again
Redensyl™
Hair Growth ActiveThis is the one aimed at the second job — restarting the follicles that stopped. It wakes follicles that have gone quiet and empty, rather than the hair you’ve still got. In its clinical studies, scalps treated with Redensyl grew over 10,000 new hairs compared to untreated ones.
Capixyl™
Density PeptideAn aging scalp runs inflamed, and inflammation shortens how long each hair gets to grow. Capixyl works on both ends of that — calming the inflammation while feeding the root each strand anchors into.
In its studies, it cut scalp inflammation by up to 48% and increased hair density by up to 79% versus untreated — outperforming the leading alternative by 81%.
RootBioTec™
Nourishing ActiveFeeds the follicle at the root and boosts the blood supply carrying nutrients to where hair is made. In its studies, it reduced shedding by up to 31% in two months.
Individual results vary. Not all users will experience these results.
How regrowth was measured
Regrowth wasn’t self-reported — it was graded. In the KilgourMD trial, each woman’s hair density was scored on the Ludwig scale, the standard doctors use to measure female hair loss, by two independent board-certified dermatologists — at the start and again at the end.
A full grade’s improvement means a visible step up in coverage, confirmed by both.

My 90 day pictures
I am happy with my results. My thoughts:
- I washed my hair daily the first three weeks to give the product the best opportunity to work; I now wash it every 2-3 days
- I apply one serum in the morning and the other at night
- I stopped blow drying my hair and let it air dry now and I think that has helped with less breakage
- I am wearing my hair shorter than I ever have which also helps with less breakage
- I just use the applicator provided and dab it on and massage it in; on nights I wash my hair I let my hair dry slightly and then apply the serum and that helps with spreading the product better
- With travel a few times I have missed a day or two applications but other than that I have been very religious about using the serums daily
- My serums each last right around 30 days

Give it 90 nights. If nothing
grows back, you pay nothing
Users report the shedding drops in the first six weeks — the scalp starts holding onto hair instead of pushing it out early. The weeks after that are when it shows: the hairs held back in the growing phase have been growing the whole time, and they come through as density where it had thinned.
Ninety nights is long enough to see both. If your shedding isn’t down and nothing’s filled in, one email and every dollar comes back — and you keep the bottles.
All it asks for is sixty seconds before bed. Two serums, straight onto the scalp. Nothing swallowed, no hormones, no side effects.
And your answers qualify you for
38% off the full two-serum protocol — for a limited time.

less shedding Balance
tipping More shedding,
less growing
6–12 months ago — You started
Hair is only ever doing one of two things: anagen, growing without interruption, or telogen, where it stops growing and sheds out later.
Studies show a GLP-1 shifts the balance — hair that should have stayed in anagen moves into telogen instead. The calorie deficit pushes more across at the same time. A healthy scalp holds about 90% in anagen. On a GLP-1 it can fall to 40–50%.
3–6 months ago — You noticed it
The first hairs that shifted finished telogen and let go — that’s what showed up in your brush and your shower drain. But that was only the first batch. You were still on your GLP-1, so more kept shifting behind them.
3–6 months ago — You came off
Most women are told the shedding settles once the GLP-1 is out. That’s true of what hadn’t shifted yet — nothing new gets pushed into telogen after you stop.
It isn’t true of what already had.
Today — It’s visible
Every month on your GLP-1, another batch moves into telogen and sheds out. And the follicles they leave behind stay empty — nothing’s pushing them back into anagen while you’re still on it.
So it builds both ways. Which is why your part typically keeps widening — more falling out each month, and less coming back to fill what already went.
Ahead — What the research shows
A follicle can sit in telogen a while and still come back. Past a point, it stops re-entering anagen at all.
You said you’re staying on your GLP-1 as long as it takes. That’s the right call for your health — but it keeps shifting hair into telogen the whole time, and more of it crosses over while it does — and the longer it runs, the more of it there is.
This timeline is an estimate based on your answers, not a medical assessment. Individual experiences vary.
Built by a Stanford dermatologistYour match: six actives that
push your hair back into growing
Before
After
AnaGain™
Hair Cycle ActiveThe one thing that moves hair back out of telogen and into anagen — reversing the shift instead of waiting on it. In its own clinical studies, it nearly doubled the number of hairs in the growing phase.
Redensyl™
Regrowth PeptideGoes after your thinnest spots, where hair has been stuck in shedding longest. It works on the stem cell that has to fire before any of it moves back into growing, and delivers the building blocks a GLP-1 depletes so every hair comes back thicker. In a clinical study, Redensyl™ grew over 10,000 new hairs in 12 weeks, without side-effects.
Capixyl™
Density PeptideYour body feeds hair last in a calorie deficit. Capixyl works on the follicle that sets how thick a strand grows, so the new hair fills in properly instead of coming in wispy. In its studies, hair density increased up to 79% versus untreated.
Procapil®
Anti-Shedding PeptideStops the next batch letting go. It reinforces the grip at the base of the follicle — so fewer healthy strands shift over while you’re still on your GLP-1. In its studies, it cut hair fall by up to 46%.
RootBioTec™
Nourishing ActiveFeeds the follicles left empty behind each shed, boosting the blood supply that carries nutrients to the root — so they can fill back in instead of sitting there. In its studies, it reduced shedding by up to 31% in two months.
L-Ascorbic Acid
Collagen SupportThe most potent form of vitamin C. Supports the collagen the root sits in and shields the follicle from the oxidative stress of rapid weight loss — so the ones still in anagen stay there.

How shedding was measured
Nobody in this category tests the finished bottle. They borrow proof from ingredients studied in a lab.
So we ran the trial on the serums themselves, two ways.
First, exactly as you’d use them. Women at home, both serums, nightly, four months. Not a patch of skin in a lab — the real routine, in a real bathroom.
Second, with something you could count. The lab washed their hair, collected every strand that came out, dried them and counted them by hand.

Day 0
Day 84Redensyl™ was measured on its own, before it went in anything.
Volunteers used it daily for three months. The same small section of scalp was photographed at day 0, day 28 and day 84 — same spot, same camera, every time. Every hair rooted inside that window was counted and marked as growing or shedding, so you could see the same follicles change over twelve weeks rather than a before-and-after of two different heads.

Almost at my goal weight 🤞
Down 47lbs and I’d made my peace with the hair going with it. It went at my temple first, the right side, and I’d been wearing my hair forward for months to cover it. Then I moved up to 5mg and it got noticeably worse. That’s when I started the KilgourMD serums.
There’s a patch of little ones there now. An inch, maybe two, all the same length, standing straight up and they won’t lie flat.
Still on my shot, 87% of the way to my goal weight!!

Shedding down!!!
I used to count strands. I’d untangle the wash-day clump and count it to make myself stop imagining it was worse than it was. 400, 500 sometimes. Six months on the shot and that was my normal.
Got the white and black bottles from KilgourMD. I don’t count anymore because there’s nothing worth counting.

Give it 90 nights. If nothing
grows back, you pay nothing
In the trial, shedding dropped in the first six weeks — fewer hairs in the drain, less in the brush. The weeks after that are when it starts showing: hair pushed back into anagen has been growing the whole time, and it comes through as length and density where it had thinned.
Ninety nights is long enough to see both. If your shedding isn’t down and nothing’s filled in, one email and every dollar comes back — and you keep the bottles.
All it asks for is sixty seconds on the scalp before bed, both serums, nothing swallowed, nothing prescribed, nothing that touches your GLP-1 or slows the weight loss down.
And your answers qualify you for
38% off both serums — for a limited time.
