Built for the man who's tried everything.
Foam, pills, shampoos, and companies that kept the money whether they worked or not.

Seven years. 34 formulas. One system we'd actually use.
No finasteride. No minoxidil. No hidden blends. Three growth actives with real human trials behind them, at full clinical strength, delivered through 0.5 mm micro-infusion past the barrier that stopped everything else you tried. And if it doesn't regrow your hair in 120 days, you don't pay.

If you only read one thing
Most of what you rub on your scalp never reaches the follicle.
It's not a willpower problem. It's a delivery problem, and that's what we spent seven years solving.
Procyanidin B2 1% · Adenosine 0.75% · Caffeine 0.2%.
The exact strengths used in published human trials. Read every one yourself, below.
Regrow your hair in 120 days, or don't pay.
Every dollar back, and you keep the kit.
How it started
It started with one question nobody could answer.
Minoxidil foam. Finasteride. Thickening shampoos. Gummies. Most men who find us have tried at least one, and when it didn't work, most were told the same word: genetic.
In 2017 we put the most popular hair-loss products side by side and asked the question none of their labels answered: how is any of this supposed to reach the follicle?
Your scalp has a barrier, and it does its job a little too well. Foams, serums and shampoos sit on the surface, where most of the active never reaches the follicle that actually grows the hair. The ingredients weren't the whole problem. They just never arrived.
And every one of those companies kept the money anyway. Not one of them had to answer for the result.
So we stopped asking “what's the best ingredient?” and started asking “what's the best ingredient that actually gets there?”
That question took seven years to answer properly. We went through more than 200 published hair studies and kept only the actives with human trials behind them. Then we put each one in at the exact concentration the trial used. No trace dosing. No hidden blends. The serum went through 34 versions before one stayed stable at full strength and still felt like nothing on the scalp.
The stamp was its own fight. The first heads went too deep and nobody wanted to use them twice. The next ones were so shallow they did nothing. It took until 2022 to lock a fixed 0.5 mm head: deep enough to get the serum past the barrier, shallow enough that it feels like tapping a fingernail on your skin. Five minutes, once a week.
Before we sold a single kit, 142 men used the system for 16 weeks each in 2023 and 2024, and told us what worked and what didn't. That was real-world testing, not a clinical trial. We haven't run our own clinical study yet, and we won't pretend otherwise. The evidence we point to is the published research on each active, linked further down this page.
We launched in 2025. Seven years from the first question to the first box.
The one idea behind everything we make
The problem was never your hair.
It was the delivery.
That's why we built a system, not another bottle. The stamp opens the way. The serum goes through it.
01
Clear the Path
0.5 mm micro-channels open the scalp barrier, clearing buildup and boosting blood flow to oxygen-starved follicles.
02
Activate the Root
The serum reaches the follicle, where procyanidin B2 and adenosine signal dormant roots back into the active growth phase.
03
Anchor the Strand
The hair shaft thickens, the root strengthens, and daily shedding drops.
How to tell we're not another scam
Six things we refuse to do.
If you've been burned before, you already know the tricks. Here's every one of them, and what we do instead.
Trace dosing
Full clinical strength
1% · 0.75% · 0.2%, the exact doses the trials used. Not a pinch so it can go on the box.
Hidden blends
Every dose, disclosed
The concentration of each studied active is published on our product page. Many brands never disclose a dose at all.
Hormonal trade-offs
Drug-free · non-hormonal
No finasteride. No minoxidil. No daily drug or hormonal trade-off.
Unproven claims
Every study on PubMed
Linked, with the trial size and its limitations. Read it yourself.
Subscription traps

Online, from your account. No phone call, no fees.
Fine-print guarantees
120 days or every dollar back
No visible change? We refund every dollar, and you keep the kit. The full terms fit on one page.
The studied formula. At full strength.
Don't take our word for it. Take theirs.
Most brands say “clinically proven” and hope you won't ask where. We give you the trial, the dose it used, what it found, and what's weak about it.
1%
Procyanidin B2
The trial Kamimura 2000 · Phytomedicine · 29 men · 6 months · double-blind, placebo-controlled
What it found +6.68 hairs per 0.25 cm² on 1% procyanidin B2 vs +0.08 on placebo.
Limitation Small cohort (19 active / 10 placebo). Supported by Takahashi 2001.
0.75%
Adenosine
The trial Watanabe 2015 · Int J Cosmet Sci · 102 men · 6 months · double-blind, randomized
What it found 80% reported at least fairly marked improvement vs 32% on the control lotion.
Limitation Comparator was a control lotion. Replicated placebo-controlled in Iwabuchi 2016.
0.2%
Caffeine
The trial Dhurat 2017 · Skin Pharmacol Physiol · 210 men · 6 months · randomized, multicenter
What it found Non-inferior to 5% minoxidil: +10.59% vs +11.68% change in anagen hair ratio.
Limitation Open-label design: no blinding, no placebo arm.
These are published trials of the individual actives, at the concentrations we use. They are not trials of the American BioLabs system, and we have not completed our own clinical study.
Honest fit
Who this is for. And who it isn't.
We'd rather lose a sale than sell you something that can't work for you.
It's built for you if…
- You're thinning at the crown, temples or hairline, or all over
- You've tried minoxidil or finasteride and want zero hormonal trade-offs
- You can give it five minutes, once a week, for 120 days
- You want to judge it by your own photos, not our promises
It's not for you if…
- You've been completely smooth for many years. If the follicles are gone, nothing you put on your scalp brings them back, and we won't pretend otherwise.
- Your hair is falling out suddenly or in patches. That's a different problem, and this isn't built for it. See a doctor first.
- You want a result in two weeks. This takes months, and we'll tell you that up front.
One last thing.
If you've been burned before, you're exactly who we built this for. The foam, the pill, the “it's genetic” shrug, the products that kept your money either way. That's why we spent seven years on this before we sold a single kit.
We can't promise it'll work for every man alive. Nobody honest can. What we can promise is that you'll know in 120 days, and if it doesn't work for you, you get every dollar back. Try it with nothing to lose.
And if you ever want to tell us how it's going, good or bad, write to us. A person reads every email.
