ElectroTrichoGenesis (ETG), also known as Cosmetic TrichoGenesis (CTG), is a little known hair loss treatment that makes some very lofty hair growth claims. How does ETG work and is it really clinically proven to treat androgenic alopecia(genetic balding)?
ETG is promoted as a safe, painless and non-intrusive. Treatment is administered via an “ergonomically shaped couch with a semi spherical hood” manufactured by Current Technology Corporation in Vancouver, Canada.
The patient reclines on the chair and the hood (with disposable liner) is placed over the head but does not make contact with the scalp. This special hood contains electrodes that deliver “specified pulsed electrostatic energy” delivered passively to the scalp by the low-level electric field generated within it.
ETG is believed to stimulate the regrowth of hair through the positive influence of the pulsed electrostatic field it generates. This field is said to stimulate “changes within the hair bulge and the follicle, stabilizing hair loss and stimulating new hair growth”. Patients receive a single 12 minute session weekly.
The following three studies on the efficacy of ElectroTrichoGenesis (ETG) as a treatment for thinning hair have been published in peer-reviewed journals:
Maddin, W. Stuart; Bell, Peter W.; James, John H. M. (1990).
"The Biological Effects of a Pulsed Electrostatic Field with Specific Reference to Hair Electrotrichogenesis". International Journal of Dermatology29(6): 446–450.Benjamin, Benji; Ziginskas, Danute; Harman, John; Meakin, Timothy (2002).
"Pulsed electrostatic fields (ETG) to reduce hair loss in women undergoing chemotherapy for breast carcinoma: A pilot study". Psycho-Oncology11(3): 244–248Maddin, WS; Amara, I; Sollecito, WA (1992).
"Electrotrichogenesis: further evidence of efficacy and safety on extended use". International Journal of Dermatology31(12): 878–80
According to the 36-week comparative, controlled study conducted on male subjects at the University of British Columbia and published in The International Journal of Dermatology, 96.7% of those treated experienced cessation of hair loss and/or hair regrowth. Decreased hair loss was seen as early as 4 to 6 weeks but many patients required more time for results.
The pilot study conducted on women undergoing chemotherapy for breast carcinoma and published in Psycho-Oncology,showed that twelve out of 13 participants had good hair retention throughout the chemotherapy period and afterwards with no reported side effects.
As with the clinically proven medical hair loss treatments Rogaine (minoxidil) and Propecia (finasteride), ETG is said to be most effective in the early stages of balding.
Although the data put forth in this article seems to paint ETG as a clinically proven and highly effective hair loss treatment, it’s important to note that the procedure is not new. The studies referenced above were published more than 13 years ago. If ETG truly works to stimulate hair growth and suppress the advancement of hair loss, why has it not become a fixture in the world’s leading hair restoration clinics? Where are all the glowing, unbiased reviews?
With no reported side effects, there may be no harm in giving ETG a try if there is a provider in your area and the fees are reasonable. However, balding men and women are encouraged to consult with an experienced and reputable hair restoration physicianin order to diagnose the cause of their thinning hair and learn about the outstanding medical and surgical options available today.
Use of low level laser therapy (LLLT) devices for treating hair loss has been heavily debated for some time by reputable hair restoration physicians and patients on our hair loss forum. While some physicians reject its use entirely, others use laser hair treatment as a regular part of their practice. Additionally, some physicians believe that laser light therapy can assist with postoperative healing after hair transplant surgery.
Shortly after the first working laser was invented in 1964, a researcher from Semmelweis University of Budapest named Andre Mester developed a theory that exposure to cold laser light (similar to UV radiation emitted by the sun) may eventually lead to cancer. To test his theory, Mester shaved a group of mice and trapped some of them in a cage with constant cold laser light exposure leaving the other half unexposed as a control group. To his surprise, the light didn’t cause cancer in any of his animal subjects. Instead, mice that were exposed to the laser light therapy grew back their shaved fur much faster than the control group. Mester named his discovery photo-biostimulation. His theory was that somehow, the laser light had stimulated the hair cells into an accelerated state of hair growth.
Today, low level laser therapy is being used as a hair loss treatment. To treat baldness with laser light therapy, laser rays are directly applied to the scalp by a mechanical device so that red blood cells are stimulated. Lasers are said to work by converting ATP (Adenosine Triphosphate) to ADP (Adenosine Diphosphate), releasing energy and causing cellular metabolic changes. During this process, additional nutrients and oxygen are provided to the scalp assisting the normal chemical processes performed by those cells, increasing overall blood circulation. Lasers, when applied to the scalp and hair, have been said to improve overall hair quality, promote hair growth, and increase hair shaft diameter.
Laser treatment devices have a similar appearance to a hood hair dryer which is placed over top of your head. The low level laser toll will rotate allowing laser rays, usually red in color, to be discharged into your scalp. Hand held devices such as the Hairmax comb have also been developed and resemble a brush in appearance.
Promoting healthy hair growth however, is not the same as the regrowth of miniaturized hairs brought on by genetic female hair loss or male pattern baldness (MPB). So what clinical evidence exists, if any, that laser therapy is an effective treatment? Below we take a closer look at the available data including exclusive interviews of leading hair restoration physicians.
Physicians have long shared varying views on whether or not laser treatment is viable. While some well respected physicians reject its use entirely, some believe that LLLT can provide marginal benefit for men and women suffering from androgenic alopecia (genetic baldness). Additionally, some physicians believe that laser hair treatment can assist a hair transplant patient’s postoperative wound healing process and expedite hair growth.
Dr. Charles (one of our well respected members of the Coalition of Independent Hair Restoration Physicians) believes it may provide similar hair loss prevention benefit to Rogaine in the mid vertex area and crown. Benefits in the frontal area include an increase in overall hair quality rather than hair loss prevention.
Dr. Charles believes LLLT works better when combined with Propecia (finasteride) and Rogaine (minoxidil). Like Propecia and Rogaine, he believes low level laser therapy may help some patients more than others and works better in patients with only minimal thinning hair.
Dr. Charles believes in helping balding men and women develop and maintain realistic expectations and he doesn’t oversell its benefits. Because lasers are free from side effects, he always tells his patients that the biggest risk is the money. Dr. Charles believes more research on laser hair treatment is needed.;
Dr. Williams of the Coalition has been using laser hair treatment as a regular part of his practice for over 2 years and feels quite confident in its success in some patients. In his experience, LLLT promotes healthy hair growth and can increase hair shaft diameter of miniaturized hair affected by genetic female hair loss and male pattern baldness in some patients.
Dr. Williams offers 16 free laser therapy sessions to local males following hair transplant procedures and encourages his female transplant patients to undergo laser light therapy for one full year at a highly discounted rate. Dr. Williams usually notices faster transplanted hair regrowth and a quicker resolution of postoperative telogen effluvium or “shock loss”, if it occurs.
Because androgenic alopecia is a progressive condition, Dr. Williams encourages male patients to use Propecia while encouraging out of town females to use the Hairmax laser comb to help maintain their existing hair. Dr. Williams would like to see more formal studies defining the benefits of lasers as a hair loss treatment, but he is encouraged by his experience with it to date.
Dr. Alan Feller (also a member of the Coalition) is one doctor who remains skeptical. "Medical lasers work in only one way, and that is to deliver energy to a target. When it strikes the target the energy is absorbed and converted to heat. That's it". Dr. Feller believes that more compelling evidence is needed to promote low level laser therapy (LLLT) as a hair regrowth solution or to stop hair loss.
study presented at the last International Society of Hair Restoration Surgery (ISHRS) meeting in Las Vegas (2007) by Maria A Muricy, MD, confirms increase in hair shaft diameter, fullness, and overall quality with laser hair treatment alone. Additionally, some statistically significant evidence reveals that low level laser therapy when combined with 5% minoxidil (the active ingredient in FDA approved Rogaine) provided noticeable cosmetic benefits for women in particular. However, this study also showed that laser hair loss treatment alone produced no statistically significant new hair growth in both men and women.
Another important issue to consider is the significance and meaning of the FDA clearance (not approval) of the Hairmax laser comb. Though some have proposed the Hairmax laser comb was only approved for safety, apparently the FDA did require Lexington International (who funded the study) to provide it with a study on its efficacy (effectiveness) in treating baldness. But this study and its results have not been released to the public since Lexington International had the option of submitting the study to the FDA privately. The obvious question then is – why would Lexington hide their study from the public if it proved the efficacy of laser hair regrowth?
While the Hairmax laser comb device was found by the FDA to be safe based on its “substantial equivalence” to previously approved laser light therapy devices and thus “cleared” (not “approved”), it was unclear to what extend the FDA reviewed or cleared it based on its effectiveness in treating hair loss. To learn more about the FDA standards for “approving” food and drugs and for “clearing” medical devices visit www.fda.gov
It appears that much of the laser hair treatment industry is now promoting their devices as “FDA Approved for Hair Loss” as if they are on par with the two only FDA approved hair loss solutions Propecia (finasteride) and Rogaine (minoxidil). However, until laser hair treatment provides compelling public evidence of its effectiveness in treating hair loss, it is quite possible that the effectiveness of low level laser therapy may be oversold by some companies. We expect that time will tell.

Try telling that to 80 million men and women who are suffering from hair loss in the United States. They will laugh at you. Yet on a daily basis we are bombarded with ads for hair loss treatments like Avacor, Hair Genesis, Fabao and Procerin that use misleading advertising to sell their products. Thanks to their persuasive messages promising to regrow hair, consumers will spend nearly one billion dollars trying to find an effective hair loss remedy and fall victim to misleading advertising like this.
Thinning hair is a source of distress for millions of men and women so it is not unusual for them to seek help from anything that sounds like it will work. Most questionable hair loss products use similar, misleading marketing techniques ranging from claims to testimonials and photos.
Many hair loss products claim to be able to restore hair through the use of drugs, herbal lotions or other exotic applications like lights, lasers or electrical fields. While many of these products have been around for years, there is little evidence that they can restore hair.
How are they allowed to make such claims? These products often use small amounts of generic drugs found in Propecia and Rogaine (finasteride and minoxidil) which allows them to make the claim to stop hair loss or they imply hair growth with 'cosmetic' claims.
Some hair loss products lead you to believe that they can stop hair loss by parsing their words. They can't come out and claim to regrow hair or stop hair loss, so they advertise vague claims like "thicker, fuller hair". This is a 'cosmetic' claim that any product can make. Be advised that cosmetic claims cannot restore hair or grow hair because they are not proven to do so.
With the anonymous nature of Internet postings, people posing as users will mislead others with false testimonials. Often, positive reviews are produced by people compensated to post these messages. Since there is no real regulation of online postings, consumers are advised to take testimonials with skepticism.
Most product advertising that claim that you can "Regrow Hair!" or make your hair 'thicker and fuller' and show a photo of a balding person with thin hair next to a photo of the same person with thicker hair covering the baldness. Photos don't lie, do they?
Well, yes they do.
You can prove it yourself. Take a photo of a head with thinning hair using a flash camera and then photograph the same head without the flash. The photo with the flash will look like a bald head and the photo without the flash will look like more hair.
Lighting, length of hair and how the hair is arranged on the head determine whether a photo of a head looks bald or not. Most people go through the same routine as balding advances: they push hair from here to there and hair spray it into place in the hope that no one will notice that we are going bald. To the extreme, this becomes the 'comb-over' hair style.
Review the photos of hair loss products you've seen. In most cases there will be just a few and they will all have misleading elements like lighting, hair style and length of hair in the 'before and after' photographs. If the products or services are really legitimate, there should be dozens of photos, if not hundreds or thousands.
Sadly, we think that the United States Food and Drug Administration and the Federal Communications Commission (agencies who regulate such issues) can stop these scams. Unfortunately, they can't. Since the FDA approved Minoxidil and Finasteride as effective in stopping hair loss, any inclusion of these products in any form enables marketing companies to make hair restoration claims.
Even the studies done for Rogaine and Propecia are not that encouraging. When Rogaine was studied (active ingredient is minoxidil), 16% of the placebo group had measurable new hair growth. Four out of twenty-five people had real, measurable hair growth when they believed they were using something that worked. Both studies were limited in time and scope. To read the studies that were done achieve FDA approval, visit the FDA web site and scroll down to Propecia and Rogaine. (http://www.fda.gov/cder/foi/nda/index97.htm )
If a person is genetically prone to hair loss and balding, FDA proven hair loss treatments may help slow the process if they are used early and often. If you are like many and have already lost more hair than you're happy with, there is only one option to restoring your own natural hair: hair transplants. Hair transplants have become an art in the restoration of natural hair which is genetically resistant to the causes of balding.
Like any surgical solution, your success depends upon the quality of the doctor you choose. Doctors who are successful in restoring a natural looking head of hair are carefully reviewed by the Coalition of Hair Restoration Physicians for membership in this exclusive organization. They must allow access to past patients, confirm their training and provide photos and videos of their patients.
While hair transplants are not possible for everyone, they are now more natural and affordable than ever before.

Follicular unit extraction is a minimally invasive procedure for performing follicular unit hair transplantation. However, unlike the predominant follicular unit transplant procedure, in which a strip of donor tissue is removed and dissected under magnification, the FUE procedure uses a small punch to extract each follicular unit one by one.
Both the strip excision and FUE procedures create 1, 2, 3, and 4 hair follicular unit grafts that are then transplanted into the balding area in the same manner. The primary difference between these two procedures is the technique used to harvest the follicular unit grafts.
The common strip excision method of performing follicular unit hair transplantation involves surgically excising a thin horizontal strip of bald resistant skin from the donor area.
Strip Excision Procedure
This donor area is then sutured together. These sutures (either stitches or staples) are then typically removed about ten days after surgery. Some physicians use dissolvable sutures so that no removal is needed.
Once this linear incision is fully healed the patient is left with a thin horizontal scar in the back of the head. This scar is typically hard to detect since the surrounding hair conceals it, even when the hair is cut short.
To view a video of an actual strip excision surgery.
With the Follicular Unit Extraction or FUE procedure 1, 2, 3, and 4 hair follicular unit grafts are carefully extracted one at a time using a tiny punch of one millimeter or less. Often the surgeon requires the patient to buzz cut a portion of their donor area so that they are able to see the patient’s scalp.
The follicular units are extracted by placing the punch around a single follicular unit and cutting a small circle through the skin around that follicular unit. The follicular unit is then gently pulled up and away from the loose tissue underneath the skin.
The small hole left behind after the follicle is extracted then heals over the following week. Normally this small round incision contracts as it heals making the resulting round scar smaller than the size of the 1mm punch that made the incision. The FUE patient ultimately ends up with hundreds of small round white scars, which are normally not detectable once the patient’s hair grows out.View a video of an actual FUE surgery.
Advocates for the relatively new FUE procedure claim that this procedure produces less noticeable scarring and no tightness or numbness in the donor area since no donor tissue has been pulled together and sutured. Many patients and physicians find the claim that FUE produces less visible scarring to be debatable.
Some physicians and patients also have concerns about the relatively new FUE procedure, such as the lack of formal studies regarding the percentage of follicles that may or may not be transected during the sight unseen extraction process.
In addition, since the physician must personally extract all follicles, one by one, the FUE procedure is very physician dependent and thus very expensive. The FUE procedure also requires considerably more time in surgery to move a given amount of hair to the balding area.
The standard strip excision procedure has the advantage of utilizing a collaborative team to carefully create the grafts once the donor tissue is removed in a strip. This collaborative approach enables a well trained staff to do sessions of 2,000 to 3,000 all follicular unit grafts in a single day. This team approach enables a patient to get a much larger number of grafts/hairs in one sitting at a much lower cost per hair than with the FUE procedure.
However, some believe that despite being relatively costly the FUE procedure may be appropriate for patients who have very limited elasticity in their donor area or who only need a small number of grafts.
Soon after the Middle Ages wigs became popular for women. Then in the 1600’s the flamboyant and incredibly vain King Louis XIV of France lost his hair from a severe illness and took to wearing gigantic wigs thus setting the fashion for most men of his day.
These enormous creations featured such items as cages with live birds and could weigh up to 20 lbs.!
By the 1700’s England made another contribution to bad hair loss concealers. This was the age of the long, curly, and powered wigs. Even today, English judges and lawyers continue this practice. Thus the expression for those in authority – “Big Wigs.”
The early 1800’s is renowned in hair loss circles as the age of the con men. There were hundreds of so-called “hair loss solutions” and many lasted well into the late 1900’s.
These treatments were marketed by fast-talking “doctors,” skilled only in bravery and possessing nerves of steel considering they were conning hardened cowboys and outlaws!
The salesmen hawked their products from the safety of their side shows and “Wild West” spectaculars. They used endless tricks to get people to buy their products, including rubbing grease into their hair to make it look thicker.
During the past several decades, superstition, old wives tales, and guess work has gradually been replaced by science.
In 1939, a Japanese dermatologist, Dr. Okuda, published a revolutionary method in a Japanese medical journal that would lay the ground work for modern hair transplantation.
This method involved using hair transplant grafts to correct lost hair from various areas, including the scalp, eyebrow, and moustache areas. However, this study didn’t make an impact in the Western Hemisphere due to the interruption of World War II.
In the late 50’s one physician in particular, Dr. Norman Orentriech, began to experiment with the idea of relocating or transplanting the hair on the back and sides of the head to the balding areas.
Dr. Orentriech’s experiments showed that when bald resistant hairs from the back and sides of the head were relocated, they maintained their bald resistant genetic characteristic regardless of where they were transplanted.
This principle, known as “Donor Dominance”, established that hair could be transplanted from the bald resistant donor areas to the balding areas and continues to grow for a life time. This laid the foundation for modern hair transplantation.
During the 60’s and 70’s surgical hair restoration grew in popularity. However, the standard procedure used large grafts that were removed by round punches and often contained many hairs.
Completed Result after Multiple Sessions of Large Grafts
This now outdated technique could achieve a full look if a patient completed all planned sessions. However, a patient was typically limited in the manner they could style their hair.
Patients who stopped short of completing all planned sessions were left with hair loss solutions that looked obvious and unnatural.
Such uncompleted hair restoration results are some times referred to as “barbie doll hair” or “corn rows”.
Many who have had these older techniques now refine or complete their hair transplants with today’s very refined techniques to achieve a natural look that they can style in any manner.
