Your serum is sitting on the surface.

Topical serums lose 95% or more of their active ingredients to the skin barrier. They sit on the stratum corneum — the outermost layer of dead skin cells — and never reach the dermal papilla where hair growth actually happens. Our 0.5mm micro-infusion system creates hundreds of microchannels that deliver the full formula directly into the upper dermis. Your actives reach the follicle. Every single one.

The Science

6 biological pathways.
One system.

  • DHT modulation — Procapil + Capixyl inhibit 5-alpha-reductase at the follicle level
  • Stem cell activation — Redensyl targets outer root sheath stem cells (ORSc), reactivates dormant follicles
  • Growth factor signaling — GHK-Cu triggers Wnt/β-catenin pathway for follicle regeneration
  • Anagen prolongation — Adenosine at 0.75% extends the active growth phase
  • Anti-testosterone support — Caffeine counteracts testosterone-driven follicle suppression
  • Vasodilation — Arginine + Caffeine increase blood flow to the follicle bed

Redensyl — 84-Day Study

17% increase in anagen hairs

International Journal of Cosmetic Science, 2014

Full Transparency

Every ingredient. Every percentage.

We publish our concentrations because we have nothing to hide. Every active is dosed at the exact level used in published clinical studies.

Redensyl

3.0%

Targets hair follicle stem cells (ORSc), reactivates dormant follicles, promotes anagen re-entry. Completes the RCP trio.

View study

Capixyl

2.5%

Acetyl Tetrapeptide-3 + Red Clover Extract. ECM remodeling and DHT modulation via biochanin A isoflavone.

View study

Procapil

2.5%

Biotinyl-GHK + Apigenin + Oleanolic Acid. DHT inhibition, follicle anchoring, and scalp vascularity support.

View study

Adenosine

0.75%

Anagen prolongation at the exact concentration from the landmark Japanese clinical trials. Extends the active growth phase.

View study

GHK-Cu (Copper Tripeptide-1)

0.05%

Follicle regeneration via Wnt/β-catenin signaling. Stimulated hair follicle elongation and DPC proliferation in vitro (Pyo et al., 2007).

View study

Caffeine

0.5%

Counteracts testosterone-driven follicle suppression. Enhances blood flow to the follicle bed in combination with Arginine.

11.5% total active load — published and verified

Three steps. Five minutes.

One session every 7–10 days. No daily routine.

01

Open

Tear open the sterile foil pouch. Each cartridge is single-use and pre-filled with 5ml of clinical-grade serum.

02

Apply

Press the device against thinning areas. 0.5mm microneedles create channels while dispensing serum directly into the dermis.

10d

03

Repeat

One session every 7–10 days. Full results at 6+ months of consistent use. Hair biology is slow — anyone promising faster is lying.

Frequently asked questions

Delivery. Topical serums lose 95% or more of their active ingredients to the skin barrier (stratum corneum). They sit on the surface and never reach the dermal papilla where hair growth actually happens. Our 0.5mm microneedle system creates hundreds of microchannels that deliver the full formula directly into the upper dermis — right where the follicle stem cells and dermal papilla live. Lower concentration, higher efficacy. Delivery matters more than dosage.
Reduced shedding: 4–6 weeks. Visible new growth: 3–4 months. Full results: 6+ months of consistent use. Hair biology is slow — the follicle growth cycle takes months to complete. Anyone promising visible results in weeks is lying. We'd rather set honest expectations than overpromise and disappoint.
The 0.5mm needles create a mild tingling sensation. Most users describe it as a light scratching feeling — far less uncomfortable than a tattoo or blood draw. The needles are thin (32-gauge, 0.23mm diameter) and only penetrate the upper dermis. Mild redness is normal and typically fades within 24–48 hours. The Allantoin in our formula supports post-treatment recovery.
Different approach. Minoxidil is a vasodilator — it works through one pathway (blood flow). We target six pathways simultaneously: DHT modulation, stem cell activation, growth factor signaling, anagen prolongation, anti-testosterone support, and vasodilation. Minoxidil has decades of FDA-approved data. We have ingredient-level clinical evidence at published concentrations. Many customers use both — they're complementary, not competitive.
We haven't run one yet — and we'd rather be honest about that than pretend. Every individual ingredient in our formula has published clinical data at the exact concentrations we use. We cite those studies directly and link to them. Running a proprietary trial on the complete formulation is on our roadmap, but we won't make claims we can't back up.
We offer a 90-day money-back guarantee. If you don't see any improvement after consistent use, contact us at hello@follicleand.co and we'll issue a full refund. Not everyone will respond to peptide-based treatments — genetics, stage of hair loss, and consistency all play a role. We say that upfront because honesty matters more than conversion rate.
