Exosome, PDRN & NAD+ — the 3 actives behind scalp mesotherapy, now needle-free at home.
A micro-spicule delivery system drives all three deep into the scalp — the way a clinic’s needles do. NAD+ re-energizes tired cells, Triple PDRN rebuilds the barrier, and Exosome signaling wakes dormant follicles back up.
The Scalp Shot is applied directly to the scalp once a week — and left on to work.
If you’ve tried shampoos, serums, and supplements and watched your part keep widening, here’s the uncomfortable reason why: almost none of it ever reached the problem.
Your follicles don’t live on the surface of your scalp. They live inside it — under a skin barrier built to keep things out. So when a serum sits on top, the actives mostly stay on top. That’s the wall ordinary hair care can’t get past.
Dermatologists found one way through: scalp mesotherapy — using fine needles to inject regenerative compounds straight into the living tissue. It works. But it’s $300–$600 a session, it takes a course of them, and… needles. In your scalp.
The science was never the problem. The needles, the appointments, and the bill were.
So a pH Lab biotech team asked a sharper question: what if you could get the same three actives past the barrier — without a single needle? That’s the entire reason the Scalp Shot exists.
01How it gets in — without needles
The Exosome, NAD+ & Triple PDRN Scalp Shot isn’t a shampoo and isn’t an ordinary serum. It’s a concentrated, leave-on cellular treatment — one 15 ml vial, once a week, across a 4-week cycle. You don’t rinse it out; it stays on so it can work.
What lets it act like a clinic treatment instead of a cosmetic is the delivery system — the part every other serum is missing:
Micro-spicules: microscopic plant-based channels that open the scalp barrier the same way a needle does — so the actives actually get in.
Derived from hydrolyzed sea sponge, these micro-spicules create thousands of temporary micro-channels the moment you massage the Shot in. Those channels are the doorway — and the doorway is the whole game. Without it, even the best actives never reach the follicle. With it, all three go where mesotherapy needles put them: into the living layers of your scalp.
Micro-spicule delivery: actives reach the living tissue instead of resting on the surface.
023 actives, 3 jobs — working as a system
Once the channels are open, this isn’t a random “hair vitamin” blend. It’s three signal-grade biotech actives, each fixing a different point of failure — in the right order.
NAD+ · 6,000 PPM — the fuel
Aging and stress drain the cellular energy a follicle needs to grow hair. This high, measured 6,000 PPM dose floods tired scalp cells with NAD+ to switch their energy production back on. Dead soil can’t grow anything — first, you re-energize it.
Triple PDRN — the repair crew
A three-source DNA-fragment complex (Salmon · Cica · Arginine) that rebuilds the broken scalp barrier and re-anchors each root. This is why shedding slows: hairs stop letting go.
Exosome — the wake-up signal
The breakthrough layer. Exosomes are the body’s own messenger molecules; here they carry one instruction to sleeping follicles — reactivate. This is what turns dormant follicles back on.
Protein & peptide complex — the finish
Reinforces keratin bonds so the new hair that comes in is visibly thicker, stronger, and more resilient — not fine and fragile.
Fuel it, repair it, signal it, strengthen it. That sequence is what a single needle can’t do — but a weekly Shot can.
03Your hair didn’t leave. Your follicles fell asleep.
This is the part almost no one tells you — and it changes everything about whether you can get your hair back.
Thinning is rarely about follicles that are truly gone. Far more often they’ve gone dormant: starved of energy (low NAD+), choked by a broken barrier (where PDRN comes in), and missing the signal to keep producing (where Exosome comes in). They’re still there. They’ve just powered down.
A dormant follicle isn’t dead. It’s asleep — waiting for the right signal to switch back on.
That’s the whole design of the Shot. It doesn’t promise growth out of nowhere — it does something far more believable: it re-supplies the energy, repairs the ground, and sends the exosome signal that tells follicles you’d written off to wake up. You’re not starting from zero. You’re reactivating what’s already yours.

04You’ll feel it working in the first 60 seconds
The tingle isn’t a side effect. It’s the proof.
Every shampoo and serum you’ve tried felt like… nothing. That’s the tell — nothing was getting in. The Scalp Shot is different: within a minute of massaging it in, you’ll feel a mild tingle for 10–20 minutes. That’s the micro-spicules opening channels and the actives moving below the surface, exactly as designed. It’s the first hair treatment you don’t have to take on faith — you can feel it reach the place that matters.
05The 28-day data is hard to argue with
This is where biotech separates from beauty marketing. In independent 28-day testing, the numbers weren’t soft:
A 3.2× faster growth rate and 87% reporting new growth in four weeks is not what you expect from something you do once a week in your bathroom. It’s what you expect from a clinic — which is the entire point. Backed by a 4.9-star average across 24,000+ verified users. See what they reported →
“I’d looked into clinic mesotherapy and nearly fainted at the price. This gives me that same ‘it’s actually penetrating’ feeling — the little tingle — for a fraction of it. By week three my part wasn’t the first thing I saw in the mirror anymore.”
Renata M., 46 — Seattle, WA
User-reported results over a 4-week cycle. Individual results vary.
06The 4-week cycle, week by week
One vial = one 4-week cycle. Activation → repair → reactivation.
The channels open
Micro-spicules open absorption pathways; the 6,000 PPM NAD+ delivers an energy surge to the scalp. This is when the tingle is most noticeable.
The barrier rebuilds, shedding slows
Triple PDRN begins restoring the scalp barrier and strengthening root anchoring — most users report visibly less shedding by now.
Dormant follicles switch back on
Exosome signaling activates sleeping follicles; new growth becomes visible and strands come in thicker and more resilient.
“I’m a scientist by training, so the PPM and the actual delivery mechanism are what sold me — this reads like a biotech product, not a beauty product. Four weeks in, the baby hairs along my hairline are undeniable.”
Dr. Priya N., 51 — Boston, MA
07Clinic mesotherapy vs. at-home Scalp Shot
| Clinic mesotherapy | Ordinary serum | Scalp Shot | |
|---|---|---|---|
| Bypasses the skin barrier | ✓ (needles) | ✕ | ✓ |
| Exosome + Triple PDRN + NAD+ | varies | ✕ | ✓ |
| No needles, do it at home | ✕ | ✓ | ✓ |
| Cost | $300–$600+ / session | $20–$60 | $34 / cycle |
| Money-back guarantee | ✕ | ✕ | 60 days |
One clinic mesotherapy session can cost more than a year of the Scalp Shot — and you’d need several sessions. A full 4-week cycle of the same three actives, delivered the same way, is $34. That’s the math that’s pulling women out of the waiting room.
Run a full cycle. Risk nothing.
Try the complete treatment. If you don’t see and feel the difference, return it for a full refund within 60 days — even an empty vial. The risk sits with pH Lab, not you.
Here’s the honest way to think about it. You’ve already spent on products that sat on the surface and did nothing. This is the first one engineered to get past the surface — fueled by NAD+, repaired by Triple PDRN, signaled by Exosome — with 28-day data and a 60-day guarantee behind it. The only thing left to lose is more time.
