"After 4 months I started to see promising changes. My hair feels healthier and I've noticed new growth coming through."

It starts with your hair growth cycle
Every hair on your head moves through three phases. When too many follicles get stuck resting, your hair looks thin and lifeless.
Anagen — the growth phase
Follicles actively produce new hair. The longer and healthier this phase, the thicker your hair.
Catagen — the transition phase
Growth slows and the follicle begins to shrink and prepare to rest.
Telogen — the resting phase
The follicle is dormant. When too many follicles linger here, hair thins out and density drops.
The problem: in thinning hair, too many follicles are stuck in the resting (telogen) phase. The Growcomb is engineered to do one thing — gently nudge those dormant follicles back toward the growth phase.
What is ETG?
ETG stands for Electro-Tricho-Genesis — and the name explains exactly what it does.
The Growcomb emits a gentle, pulsed electrostatic field through a row of glass diodes. As you comb, that field makes contact with the roots of your hair follicles — designed to kickstart dormant follicles back into the growth phase.
- No drugs, no hormones — nothing is absorbed into your bloodstream
- A pleasant, tickly sensation — most users find it relaxing, not uncomfortable
- Certified to the same standard as FDA-cleared electrostatic devices
A precisely controlled, low-level electrostatic field — the active ingredient, minus the chemicals.
From trichology, the science of hair. The field is tuned specifically for the follicle.
The goal: the formation of new, healthier growth from follicles that had gone quiet.

The Growcomb in action — patent-pending ETG technology.
A smarter way to fight hair loss
No pills. No daily chemicals. No ongoing bills. Just a few minutes with a device built to last a lifetime.

Effortlessly easy to use
Simply brush the glass diodes through your hair for a few minutes. No mess, no routine to maintain — most users do it in bed before sleep.

No on-going costs
One payment, then it's yours for life. No monthly refills, no subscriptions, no prescriptions to renew — it simply recharges.

Patent-pending ETG tech
The Growcomb's Electro-Tricho-Genesis technology was developed in-house by design engineer Bernhard Rudert.
Zero drug side effects
Because nothing is absorbed into your body, there's no hormonal disruption and none of the side-effect risk of oral hair-loss drugs.
Rechargeable & built to last
A single charge lasts more than a week of daily use. Automatic shut-off after 10 minutes means you can never overdo it.
For men & women
In testing, female subjects responded just as well as male subjects — making the Growcomb suitable for thinning hair of any kind.
The Growcomb vs typical hair-loss products
Most hair-loss treatments rely on drugs you take forever. The Growcomb takes a completely different approach.
| The Growcomb | Typical Hair-Loss Products | |
|---|---|---|
| Side-effect risk | ✓ None | ✗ Potential side effects |
| Affects your hormonal system | ✓ Never | ✗ Hormone-disrupting chemicals |
| Ongoing cost | $297 once | Expensive, forever |
| Lifespan | ✓ Rechargeable, lifetime use | Runs out — reorder monthly |
| What happens if you stop | Device is yours to keep | ✗ Hair loss resumes |
| Daily experience | ✓ Easy, quick & enjoyable | A chore you can't skip |
Three simple steps, ten minutes
No complicated protocol. Most people use the Growcomb in bed, right before they go to sleep.
Choose your power setting
The Growcomb has four power settings. Begin on 1 or 2 — the sensation is tickly, but most people find it quite pleasant.
Gently comb your hair
Brush the glass diodes slowly through your hair across the thinning areas, letting the electrostatic field reach the follicle roots.
Let it finish
The Growcomb shuts off automatically after 10 minutes. Recharge less than once a week. For best results, follow with Maxoxidil at bedtime.

from the
design engineer
"I built the Growcomb for people the drugs had failed."
Getting a device like this through the full FDA hair-regrowth approval process takes years and millions of dollars — something only the largest pharmaceutical companies can shoulder. So while the Growcomb is certified to the same standard as FDA-cleared electrostatic devices, we don't make formal FDA regrowth claims, and we'd never pretend otherwise.
What I can tell you is why I designed it: I wanted a drug-free option for the people who'd tried everything else and were tired of side effects, monthly bills, and false promises. Every Growcomb is built to that mission — and stands behind a 60-day money-back guarantee.

After using the Growcomb consistently for about 4 months, I’ve started to see some promising changes. My hair feels healthier and I’ve noticed new growth, especially on my crown. Consistency is key so I’m planning to stick with it for at least a few more months before giving it a proper assessment.
losing fewer hairs when I shower
It does work, but you must be consistent with it. After a month, I noticed a very slight change, but after three months, my hair is much thicker and my has grown five inches! I’ll keep going for another six months and post a picture then.
Hair looks a little thicker after a few months using it everyday. I’ll continue to use it while I watch TV in the evening.
Alright, 5 months using the Growcomb and wow! My receding hairline is making a slow but sure comeback. No, it’s not like I suddenly have a full head of hair again, but those thin patches are looking fuller for sure.
