The Growcomb: A Review

There are plenty of devices on the market that promise to treat hair loss and reverse balding.

The majority of these devices, while they may seem effective in the short-term, are typically just temporary solutions for a lifelong problem.

The fact is, there is no cure for hair loss. You can work to treat the underlying cause, however. One way to do that? With the Growcomb.

What is the Growcomb?

The Growcomb is a device that emits electrostatic pulses to the scalp. These pulses stimulate the nerves, just as your body’s own bio-currents do as part of the healing process.

Let me explain.

When the body is injured, it releases its own bio-currents as a way to stimulate the healing process. These currents are so insignificant that they’re indistinguishable to humans. What matters, however, is that the nearby nerves pick up on these signals and get to work.

The nerves send the currents to nearby tissues so as to signal them to begin repair. This is mediated by the nervous system. The body’s natural healing process will then begin.

If the body already does this naturally, then why the need for a Growcomb or other such device?

In those with pattern baldness, these signals may be inactive.

This is likely a result of scalp calcification which occurs during the progress of pattern hair loss. With the bio-currents unable to effectively travel to the nerves, there is no way for the surrounding tissues to signal their need for repair. The skin will continue to calcify and fibrose if not treated.

You may be wondering how the Growcomb’s currents can be delivered if the body’s natural ones cannot.

The use of the Growcomb can help to reverse scalp tension which is believed to be the cause of pattern baldness. It can also increase blood flow to the area, which ensures efficient oxygen and nutrient delivery.

The Growcomb, then, will remediate the long-term issue while ensuring the repair of damaged tissues and reverse the effects of pattern balding.

The Science Behind the Growcomb: ElectroTriGenesis (ETG)

To understand how the Growcomb works, you must know more about its technology.

The Growcomb uses ElectroTriGenesis (ETG) technology as a way to stimulate the body’s natural electrostatic pulses.

What does this mean?

ElectroTriGenesis literally means “the use of electrostatic pulses (electro) to stimulate new (genesis) hair follicles (tri, or trichology).”

The Growcomb’s patented ETG technology is thought to help stimulate hair growth where pattern baldness has taken place.

Scalp Tension: The Underlying Cause of Pattern Baldness?

There are quite a few theories when it comes to the cause of pattern baldness, also known as Androgenetic Alopecia (AGA).

The current most commonly believed theory is the DHT Sensitivity Theory.

Dihydrotestosterone (DHT) is an androgen sex hormone that is catalyzed in many tissues throughout the body. These include the prostate gland, skin, hair follicles, liver, and brain.

The main role of DHT is that of secondary male characteristics, or what most people think of when they think of “maleness.” For example, facial hair, a deeper voice, and increased muscle mass.

Both men and women produce DHT (which is formed from the interaction between testosterone and the enzyme 5-alpha-reductase), though men have it present in higher amounts.

If DHT is supposed to be present, then, how can it cause pattern baldness?

The theory posits that high levels of serum free DHT may be the cause of pattern baldness in men and women with androgen sensitivity. This is because the more DHT there is within the bloodstream, the more chances it has to connect with androgen receptors at the hair follicle.

When this happens in men and women with androgen sensitivity, the hair follicle will miniaturize as a result. This means that the follicles will become less capable of supporting hair growth and, over time, the miniaturized hairs will shed.

You’ll notice that many hair loss products on the market are created to target DHT. Their goal is either to block the enzyme associated with its production (5-alpha-reductase) or to block the androgen hormone itself.

These treatments may provide you with temporary results, but the side effects (such as loss of libido, inability to ejaculate, etc.) aren’t often worth it.

In addition to these short-term treatment options, there are also questions that the DHT Sensitivity Theory doesn’t answer. For example:

  • Why are DHT levels higher in AGA-prone scalp tissues?
  • What causes the classic pattern of hair loss?
  • Why does androgen suppression stop AGA, but it doesn’t regrow all hair?

That’s where the Scalp Tension Theory comes in.

Scalp tension refers to a tightening of the galea layer, which is a fibrous tissue that connects the scalp’s muscles and the outermost layer of the scalp.

According to the Scalp Tension Theory of hair loss, the true underlying cause of hair loss is chronic scalp tension. A brief breakdown of the theory goes as follows:

  1. Chronic tension of the scalp’s galea layer triggers an inflammatory response.
  2. The body recruits anti-inflammatories, including DHT, to the site.
  3. DHT attaches to the androgen receptors found on the follicles.
  4. The presence of DHT leads to the arrival of transforming growth factor beta 1 (or TGFβ-1), a signaling protein which is a precursor to fibrosis (R).
  5. A combination of the tension and the presence of TGFβ-1 triggers further inflammation. As such, blood flow is restricted which causes the follicle to miniaturize and a reduction in nutrient and oxygen delivery.
  6. The scalp will take on the classic pattern of balding. If allowed to progress, the scalp’s tissues will calcify making new hair growth impossible.

The Scalp Tension Theory doesn’t completely invalidate the DHT Sensitivity Theory. Instead, it explains why there may be increased levels of DHT at the scalp and how its presence, in addition to chronic tension, may trigger the pattern of baldness characteristic of AGA.

So, how does scalp tension come about?

As suggested by Robert S. English Jr., this tension is “mediated by pubertal and post-pubertal skull bone growth and/or the overdevelopment and chronic contraction of muscles connected to the GA (R).”

Now that you understand the Scalp Tension Theory, you may be wondering if there’s an effective way to combat it.

There are a few possibilities when it comes to reducing scalp tension and reversing its effects. One tool in particular is the Growcomb.

A Look At the Research

It seems that ETG technology has only become more popular in recent years. There is one research study from 1990, however, that sheds some light on how the device might work.

The study followed two groups of hair loss sufferers. The first group was the control group, and the second group was the treatment group.

The treatment group received administration of a pulsed electrical field over the course of 36 weeks.

To determine the efficacy of the treatment, the mean hair count of both groups was taken at baseline and then at the end of the study.

After 36 weeks of treatment, the treatment group saw a 66.1% hair count increase over baseline. This is in comparison to the control group who only saw a 25.6% increase over baseline.

What’s more, the majority of the treatment group (29 out of 30 subjects, or 96.7%) exhibited signs of hair regrowth or no further hair loss during the treatment period.

The researchers had a few theories as to how the treatment worked.

They posited that the electrophysiologic effect had a similar effect on the hair follicle as has been documented with respect to bone fracture and soft tissue repair enhancement. They further suggest this may “cause increased cell mitosis through calcium influx, involving both the hair follicle sheath and dermal papilla cells.”

Another thing of note from the researchers is the lack of side effects associated with the treatment. This is fantastic news for hair loss sufferers who are coming off of bad experiences with hair loss drugs.

How the Growcomb Can Reverse Scalp Tension

The Growcomb is thought to work in two ways.

First, it delivers the electrostatic pulses through the scalp’s hardened tissues as a way to break down calcification and reverse its effects.

It does so by targeting chronic areas of tension and increasing localized blood flow. In this way, the scalp is able to regain its proper function, and the hair follicles are once again able to receive the blood, oxygen, and nutrients they require.

As part of this process, new hair follicles may also be able to establish themselves.

Second, it stimulates the hairs to grow thicker and fuller. This leads to healthier overall hair growth.

Are you worried that the electrostatic pulses won’t be strong enough to make their way through the hardened skin? The good thing about the Growcomb is that it varies the intensity and duration of its pulses. The scalp will never become accustomed to these pulses.

The Growcomb is not an immediate fix for hair loss.

Instead, when used consistently, the device aims to reverse the damage caused by years of scalp tension so your scalp can once again grow hair as it was meant to.

How to Use the Growcomb

The Growcomb is easy to use, and it only takes 10 minutes per day.

The Growcomb should only be used on dry hair.

Begin at the hairline. Place the teeth of the comb against your scalp, and gently begin to move the comb in small, circular motions. The motions should become just intense enough to make your scalp tingle.

The motions will start at the hairline, and then you’ll move to the crown, vertex, and base of the scalp. You want to be sure to hit all areas of the scalp with equal intensity. This will ensure excellent blood flow throughout the scalp.

The entire process should take you just 10 minutes each day.

Setting Your Expectations

When you first undergo a new treatment, it’s common to be filled with many hopes and fears.

It’s important to understand that the Growcomb device, and ETG in general, doesn’t promise miraculous results. You won’t see regrowth overnight, and you’re unlikely to see full regrowth if you’ve been bald for any number of years.

What the device does offer, though, is a combination of technology and physiology as a way to treat the underlying cause of your hair loss.

So if you’re looking for a long-term answer to a permanent problem, the Growcomb may be right for you.


Is the Growcomb a legitimate hair growth device?

While there is still much scientific research to be done, there is promise in the few trials and studies which have been carried out on the technology.

Of course, you shouldn’t expect the Growcomb to treat your hair loss overnight. Years of chronic scalp tension have brought you here, so it will take time to reverse its effects.

The Growcomb only requires a few minutes of your time each day, so there’s no risk but lots of potential.
