Our study showed the Growcomb improved the thickness and quality of female subjects just as well as male.
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.
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.
How does the Growcomb work?
All hair follicles go through 3 phases known as the hair growth cycle before shedding:
1: Anagen (growth) phase
2: Catagen (transition) phase
3: Telogen (resting) phase
For someone with perfectly healthy hair, the majority of the hairs are in the growing phase, with a much lower percentage in the resting phase.
If too many hairs are in the resting phase, your hair appearance itself will be thin, lifeless, slow-growing and fall out easily.
The Growcomb uses a patent pending technology, known as ETG to optimise the hair follicle growth phase.
Results may vary, but as seen in the before and after photos from our study which you can see here, the results can be thicker, stronger, healthier hair with more life.
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.
Patrick had extreme hair loss throughout the top of his scalp. The crown area of exposed scalp was approximately 6cm wide. And at the front the centre parting was 4cm wide.
After using the Growcomb, Patrick's crown area hair loss had reduced from 6cm to 2cm. At the front, the centre parting had reduced from 4cm to 3cm. Overall hair quality and density was quickly improving.
What is ETG?
ETG stands for electrotrichogenesis.
If we break down this word into its component parts we get:
Electro = using electricity
Tricho = referring to the hair
Genesis = the formation of something new
The Growcomb works by emitting a pulsed electrostatic field through the glass diodes which come in contact with the root of the hair follicle.
This helps kickstart the hair follicle back into growth phase.
Hairguard has developed and has a patent pending on this technology lead by senior product developer Bernhard Rudhert so that anyone with thin, receding and lifeless hair can benefit from this amazing scientific discovery.
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 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.

Alex's 60 day 'hair-selfie' challenge:
Although Alex's 'hair selfies' are of low quality, we can still see just how much his hair improved after 30 and 60 days of using the Growcomb. Starting with photo on the left at day 0, then the middle photo (day 30), and then the photo on the right at day 60. Alex has gone from almost his complete top scalp being visible to almost complete coverage in just 60 days.
