The Growcomb uses patented ETG technology to help stimulate the hair follicles, and optimise hair follicle growth phase. See user results below.

Cuong's results:

Cuong had severe diffuse thinning over the entire top scalp, with the crown being the worst area with the most visible scalp. Without improvement the best option may have been a shaved head.

After using the Growcomb, Cuong had noticeable thickness and density improvement with an approximate +65% overall increase in visible hair coverage.

What is ETG?

It's funny to think, but there's a very specific and scientific reason that our hair starts receding and thinning at the front first. 

It's known as as the Hamilton-Norwood scale. 

Take a look at the picture below and see which stage you're at:

The thing is, unless you do something about it now at the root cause, in two years time you'll probably be at the next stage.

Back to the pattern thing... 

Why does hair loss happen in this very specific pattern? 

Take a look at this image below:

Jeremy's results:

Jeremy was a NW4 with severe widow's peak and balding crown area with the condition continuing to worsen. The crown area thinning was approximately 6cm in diameter.

After using the Growcomb, Jeremy's bald crown area reduced from a diameter of 6 cm to 2.5 cm with the centre also regrowing new vellus hairs. Frontal hairline was improved in thickness and density with temple area moving visibly forward.

Aman's results:

Aman's centre parting was becoming larger and more obvious every month. The scalp was clearly visible and overall the hair quality was quite thin and getting worse. The visible scalp extended right from her frontal hairline to the back of her head.

After using the Growcomb, Aman's centre parting reduced in size from 1.5 cm to just  0.5 cm as well a reduction in length. Her overall hair quality thickness and volume increased noticeably too.

Eric's results:

Eric had severe thinning at the frontal area and mild to moderate thinning over the rest of the top of the head to the point where completely shaving it off may have been the best choice.

After using the Growcomb, the mid section of the top of Eric's head improved the most as hair thickness improved. Generally the hair was observed to be growing through thicker and stronger. The frontal area went from being almost completely bald to shows signs of strong new growth.

Ken's results:

Ken was losing significant hair around his crown area, although his hairline remained fairly strong, there was some minor general thinning on top.

After using the Growcomb, his crown bald spot had become much less visible and reduced in size from about 5cm to 2.5cm. The overall hair quality on the top had improved in thickness and lustre

1: Choose your power setting.

The Growcomb comes with 4 power settings. To get started you'll want to choose power setting 1 or 2, until you get used to the sensation of the pulsed electrostatic field. Once you become familiar with the feeling you can move up to setting 3 or 4. The sensation can be described as a little bit tickly, but also quite pleasant.

2: Gently comb your hair.

Once you've chosen your setting simple comb through the areas of your hair where you would like the hair to grow thicker. You'll want to lightly brush the scalp and move in circular motions allowing the ETG technology to work its magic.

3: You're all done!

After 10 minutes of use the Growcomb will automatically turn off. You're all done for today. Just make sure you cover all the intended area in 10 minutes. You'll only need to recharge the battery less than once every week. For extra fast results, comb before bedtime and then apply the Scalp Elixir after.

Frequently Asked Questions

Does this work for women too?

Clinical studies showed that scalp tension relaxers worked extremely effectively for both men and women, causing a significant amount of regrowth for both genders.

How long before I start seeing results?

Initial tests show that after 3 months results start becoming visible. Typically the treatment works like this: 30-60 days: Hair loss is stabilized, with less hairs coming out and hair follicles preparing for the growth phase. 60-180 days: Hair regrowth kicks in and the hair follicles increase in both number, thickness and tensile strength. Hair looks thicker, stronger and healthier with higher overall coverage. 180 days onwards: Continued maintenance and continued thickening, strengthening and regrowth. Individual results may vary.

How long will it take to arrive?

International delivery takes 2-14 days. We currently ship from the U.S. and U.K.

Are there side-effects from using the Growcomb?

There are no known side effects that come from scalp tension relaxers like the GrowBand. 

Some people have reported a temporary increase in sebum production which usually decreases after a few weeks. Minor swelling or irritation is also a possible minor side effect, especially to start with. However this usually resides after the scalp gets used to it. 

In general, scalp tension relaxers are a much safer treatment option than minoxidil and finasteride, both of which have significant side effects because these drugs affect the body on a biochemical and hormonal level, artificially manipulating the body. 

Scalp tension relaxers directly fights the true cause of hair loss, which is lack of blood flow making it an incredibly effective and low-side-effect treatment.

Can I use other treatments as well?

We strongly recommend using the other Hairguard products such as the Scalp Elixir, Dermastamp, Supplement and Laser Cap whilst using the GrowBand. 

However, they are not necessary to see results. In the clinical studies on the effectiveness of scalp tension relaxers, no other changes were made to the participants diet, lifestyle and hair care regime.
