Meet the “shot” that does scalp mesotherapy at home — no needles, no $5,000 transplant.
A once-a-week biotech treatment built on Exosome, PDRN & NAD+ uses a micro-spicule delivery system to drive the actives past the scalp barrier — the way a clinic’s needles do — and wake dormant follicles back up.
One vial. Once a week. The clinic effect, brought home.
For men losing hair, the options have always been bad or expensive: live with it, take pills with side effects, or pay $5,000+ for a transplant that moves hair from the back of your head to the front.
There was one thing that actually worked at the source — scalp mesotherapy, where a dermatologist injects regenerative actives through the skin barrier with needles, at $300–$600 a session. The catch: needles, repeat visits, and a bill most men won’t touch.
pH Lab’s engineering question was blunt: keep what makes mesotherapy work — delete everything that makes men avoid it. The result is the Scalp Shot.
The breakthrough isn’t a new ingredient. It’s the delivery.
Why everything you’ve rubbed on your scalp never reached the problem.
Hair follicles live under the scalp’s barrier. Topical serums sit on top, so their actives never get in. A needle works only because it physically crosses that barrier. Remove the needle, keep the crossing, and you’ve broken the clinic’s monopoly.
The micro-spicule delivery system opens the barrier the same way a needle does — without piercing your scalp.
Derived from hydrolyzed sea sponge, micro-spicules open thousands of temporary micro-channels the moment the Shot is massaged in — the doorway that lets the actives reach the living tissue where follicles actually live.
Micro-spicule delivery: actives reach the follicle, not just the surface.
3 actives. 3 jobs. One sequence.
Once the channels are open, this goes to work in order.
6,000 PPM — the fuel
A high, measured dose that re-energizes scalp cells drained by age and stress. You can’t grow anything in dead soil — first you power it back up.
Triple PDRN — the repair crew
A three-source complex (Salmon · Cica · Arginine) that rebuilds the scalp barrier and re-anchors roots. The mechanism behind reduced shedding.
Exosome — the wake-up signal
Messenger molecules that signal dormant follicles to reactivate. The layer credited with new growth.
Fuel it, repair it, signal it. That sequence is what a single injection can’t do — but a weekly shot can.
Engineered as a biotech treatment — measured actives, not a botanical blend.
Your hair didn’t die. Your follicles went dormant.
Most thinning isn’t dead follicles — it’s follicles that have powered down: starved of energy (low NAD+), choked by a worn barrier (PDRN), missing the signal to keep producing (Exosome). They’re still there. They’ve just switched off.
A dormant follicle isn’t gone. It’s asleep — waiting for the right signal.
That’s why the Shot is positioned as reactivation, not regrowth from nothing. You’re not importing new hair — you’re waking up what you still have.
The 28-day data is below ↓
A feature no other hair product has: you feel it.
Once a week, massaged in with the applicator and left on — not rinsed.
The tingle is the technology working.
Within about a minute of application, most users feel a mild tingle for 10–20 minutes — the micro-spicules opening channels and the actives penetrating. It’s the rare hair product you can actually feel reach the scalp, instead of one you simply hope is doing something.
The 28-day data
A 3.2× faster growth rate and 87% reporting new growth in four weeks isn’t what you expect from something you do once a week at home — it’s what you expect from a clinic. Backed by a 4.9-star average across 24,000+ verified users.
“I had a transplant consult booked. Cancelled it. Two weeks in the shedding dropped off a cliff; by week four my crown looked denser than it had in years. And you can actually feel it working — that tingle.”

User-reported results over a 4-week cycle. Individual results vary.
How the 4-week cycle works
Channels open, energy surge
Micro-spicules open absorption pathways; 6,000 PPM NAD+ delivers an energy surge. The tingle is strongest here.
Barrier rebuilds, shedding slows
Triple PDRN restores the barrier and strengthens root anchoring; most report visibly less shedding.
Dormant follicles switch on
Exosome signaling activates sleeping follicles; new growth becomes visible and strands come in thicker.

A transplant is five figures. A course of mesotherapy is four. A full 4-week cycle of the same category of actives — delivered the same way — is $34.
Low-risk by design
Every order ships with a 60-day money-back guarantee — even on an empty vial. For anyone weighing a four- or five-figure procedure, testing the at-home option first costs little and risks less.
