The evidence
100 men. Same treatment. One difference.
Twelve weeks. A hundred men with male-pattern hair loss, all on the same topical at the same dose. One group also had micro-channels opened in the scalp once a week — a route in. The other rubbed it on and hoped.
Hair count told the same story: +91.4 hairs vs +22.2 in the measured area.
Same formula. Same dose. The route changed. That was all.
Microcirculation After Usage
10 Minutes (After Application)
Before you get excited, read the fine print. We did.
Both groups in that study were using a drug-based topical, and the researchers used a 1.5mm roller — deeper than we build, for reasons you'll see in a second. It is not a trial of our product, and we won't pretend it is. You'd find out in ten minutes anyway.
What the study isolates is one variable, cleanly: hold the formula constant, change only the delivery route, and the outcome moves by an order of magnitude. That result doesn't belong to any ingredient. It belongs to the route.
That explains the route. It doesn't explain us. Two things do.
First: depth is a window, not a dial. Too shallow and the serum dries on the surface like everything you've already tried. Too deep and you're past delivery into injury — inflammation, the one thing a struggling follicle needs less of. When researchers compared depths head-to-head, the shallow needle beat the deep one: 0.6mm produced significantly greater gains in hair count and thickness than the control, while 1.2mm didn't reach significance on either.
That's why our head is fixed at 0.5mm. Not adjustable. Not pressure-dependent. Not “however hard you pressed this morning.” A hand-rolled device can't hold that line, and the line is the product.
Second: an open channel is only worth what you send through it. Which brings us to the formula.
Too shallow
Never crosses the barrier. The serum dries on the surface — like every foam before it.
0.5mm — fixed
Through the barrier, then stop. The actives ride the channel down to the follicle.
Too deep
Past delivery, into injury — inflammation a struggling follicle doesn't need.
Three actives. Three human trials. Three matching doses.
Naming an ingredient with a study behind it is easy — everyone does it. The study only applies if the bottle contains what the trial tested. Ours does, three times over.
Procyanidin B2
1%
Apple-derived polyphenol, tested double-blind against placebo in men with pattern hair loss. Six months: +6.68 hairs per measured area vs +0.08 on placebo (P<0.005). Terminal hairs — the thick kind that cover scalp — up 1.99 vs a loss of 0.82 on placebo.
The trial used 1%. So do we.
Adenosine
0.75%
Trialled in 102 men over six months: significantly more thick hairs, 80% reporting marked improvement vs 32% on control — replicated in a second, placebo-controlled trial.
The trials used 0.75%. So do we.
Caffeine
0.2%
210 men, six months, head-to-head against the leading 5% drug topical: non-inferior — 10.59% vs 11.68% anagen improvement, about one point apart, without the drug.
The trial used 0.2%. So do we.

A dormant follicle didn't die.
It's been producing a finer hair each cycle, and it responds in stages. Judge the system on this schedule, not on week one:
What to expect, and when to judge it
Shedding slows
You'll notice it in the drain before you see it in the mirror.
The pillow stays clean
The morning check stops turning up strays.
Fine hairs at the temples
You'll blame the bathroom light the first time you see them.
The photo tells you
Put it next to your day-one photo. Now you know.
Other people notice
Before you tell them. The 120-day guarantee covers the whole window.
The supporting cast — no inflated claims.
Niacinamide — scalp barrier and comfort between sessions. No growth claim; the research doesn't support one, so we don't make it.
D-Panthenol — measured in fibre testing to raise break stress, so new growth doesn't snap off before it counts.
Sodium hyaluronate, non-crosslinked — small enough to enter the channels and hold the actives there instead of drying on top.
The receipts
Check every number on this page.
Every figure above names its authors, its journal and its PubMed ID — you can hold all of them in your hand in four minutes. We told you the sample sizes, the designs, and the fine print that doesn't flatter us, because a page that shows you half a study isn't evidence. It's decoration.
Now do the same to the rest of your shortlist. Ask what's in it, at what concentration, and which trial used that concentration. Most brands can't answer the second question and won't answer the third.
We just answered first.
