Let’s jump right in.

 

1. Laser Hair Growth Treatment Effectiveness and Coverage

In general, the 2 key factors that influence the treatment effectiveness and coverage of hair growth devices are:
 
(a) Quantity of Lasers / LEDs / Diodes / Modules. Higher quantity and density of these laser components in the hair growth device can basically cover larger scalp area for better treatment effectiveness and coverage in general.

(b) Wavelength of Low-Level Laser Therapy (LLLT). Dallas hair transplant surgeon Dr. Sam Lam discussed the proven and painless LLLT in presentation below.
 

 
 
As revealed in the video, scientists found LLLT at wavelength between 630 nm and 670 nm has produced good hair growth results. So it is not surprised that most of the LLLT hair growth devices are using the wavelength in this optimized range.
 

Product Name	Quantity of Lasers / LEDs	LLLT Wavelength	Details
CapillusPro	272	650 nm
illumiflow	272	650 nm
Hairmax Laserband	82	655 nm
Theradome	80	678 nm
iRestore	51	650 nm
iGrow	51	655 nm

 
iRestore laser hair growth system treats hair loss by using 51 medical-grade lasers and LEDs. They also aid in the restoration of thin air and the lasers work at the 650nm wavelength. It is highly portable and comes with the LLLT helmet style.

iGrow device is designed with the same LLLT helmet style. Utilizing both red laser and LED light diodes, iGrow comes with 21 lasers and 30 LEDS at 655nm wavelength. With these total 51 medical-grade components, iGrow is FDA certified medical device in the 510 class helmets.

Theradome is designed with a Cold Laser Phototherapy proprietary clinical strength. It has a total scalp-coverage and uses 80 proprietary lasers. Its 678 nm laser light has the ability to blast your scalp and reach the base of your hair follicles.

Hairmax laserband uses 82 medical-grade lasers (no LEDs) and their patented hair parting teeth to help delivery of light energy to the follicles. However, unlike all the other devices, Hairmax laser band has a narrow coverage and needs to be adjusted at different points above your head.
 
 

 
 

2. LLLT Treatment Frequency / Time Needed Per Day

iRestore recommends to use the device every other day for 25-minute sessions. While the low-level light-therapy should give you visible results in the first 12 to 24 weeks of continued use, iRestore gives optimal results after 6 months of consistent usage. After this period, you may notice thicker and fuller hair.

iGrow incorporates the Apira Science’s proprietary dual light laser and LED design. The iGrow’s recommended treatment time is 20 minutes every day for 6 months. You may notice some baby hairs within 4 months when used daily, while you can also continue the treatment until you achieve the results you want.
 

Product	Treatment Instruction	Average Time per Day	Details
Hairmax Laserband	90 seconds x 3 times a week	~0.7 minutes
Theradome	20 minutes x 2 times a week	~5.7 minutes
CapillusPro	6 minutes x 7 times a week	~6 minutes
iRestore	25 minutes x Every other day	~14.3 minutes
illumiflow	30 minutes x Every other day	~17.1 minutes
iGrow	30 minutes x 7 times a week	~30 minutes

 
Capillus laser cap usually takes about 4 to 6 months to see a clinical effect. This gives the laser enough time to slow down the progression of hair loss. It is simple to use at home as it only requires 6 minutes of treatment daily while you go about your everyday activities.

Hairmax laserBand works slightly different than the full-coverage hair treatment and helmet-style devices. Place the laser band on your head, and gently glide the device to the back of scalp according to manufacturer instructions. Repeat the same procedure for 90 seconds, 3 times in a week. You should start seeing a new growth after 12 to 16 weeks mark.
 
 

 
 

3. Laser Hair Regrowth System – Ease of Use

Hairmax laserband is slightly different because of its head treatment coverage. You place it on the head for 30 seconds at the front, 30 seconds at the middle and 30 seconds at the back of your head – some people may find this procedure relatively troublesome vs other options. It produces a beep sound which means that the treatment time is enough for the day. It takes 90 seconds for each treatment, 3 times per week.

Capillus laser hair cap is worn like any other cap and its power cable streams from the rear middle to the power source. Once you have activated the button, it works effectively and can be used anywhere as it operates with a battery. Same applied to the illumiflow laser cap.

Unlike the handheld laser combs, the hands-free helmet style hair growth system like IGrow and Theradome do not require you to hold it with your hands throughout the hair treatment process.
 
 

Taking iRestore laser hair device for example, it is easily usable by both men and women for treatment of hair loss and restoring thinning hair.

As shown in video below, iRestore is simple to operate since you only need to place the helmet on your head, click the activate button and use it every day for 25-minute sessions, that’s it.

4. Design and Special Features

iRestore features an ergonomic design with its sturdy helmet that distributes weight evenly around your head, making you comfortable during hair treatment. It is manufactured in the GMP-certified facilities, tested to maximum compliance by the Intertek Testing Services and meets the high ISO standards.

Theradome laser hair growth system was designed by a medical therapy company in Silicon Valley. It features a full-scalp coverage design and the 80 laser diodes that emit light energy at the optimal wavelength for hair growth. It was designed with a proprietary clinical strength Cold Laser phototherapy that offers impressive results.

CapillusPro	Laser Cap	-
illumiflow	Laser Cap	-

The built-in customizable headphones make the iGrow distinctive from other brands since you can listen to your own playlist during treatment sessions. Put on the device on your head, turn it on and you can crank up your tunes as you allow the lasers do their work.

Capillus and illumiflow feature flexible fitting design with a low-level laser therapy cap. They use a distinct style from other brands with its Cap design that offers an adaptable fit to the user. Their innovative design help each cap to adapt easily to most scalps which encourages consistency of use and optimal hair regrowth results.
 
 

 
 

5. Portability and Convenience of Laser Hair Therapy Device

iRestore laser hair growth system uses a portable LLLT helmet style with a wide coverage. It features a lightweight design at only 1.7 lbs, with dimension of 10.7 x 9.2 x 6.1 inches. If you travel often, you can purchase a separate mobile pack to use the system while you are on the go.

Theradome is comfortable to wear and can be used for laser hair restoration in the comfort of your own home. It laser helmet has proven effectiveness from the experts and many patients exhibit visible hair thickening. It is convenient since you only use it two times in a week.

Hairmax laserband is easily portable due to its narrow, head coverage design. Comfortable and lightweight at 2.6 pounds, this laserband is convenient for home use and while traveling.
 
 

 
 

6. Cost, Warranty, and Money Back Guarantee / Refund.

While Theradome LH80 PRO laser helmet offers 1 year warranty, it only comes with a 7 days refund window. This is not favorable when compared to other laser hair growth systems.

For instance, HairMax laserband comes with a 5 month money back guarantee and 2 years warranty, while iRestore offers 6 months money back guarantee and 1 year warranty.
 

Product Name	Product Cost	Money Back Guarantee	Device Warranty	Latest Price
iGrow	$$	6 months	1 year
iRestore	$$	6 months	1 year
Hairmax 82	$$$	5 months	2 year
Theradome	$$$	7 days	1 year
illumiflow	$$$	30 days	1 year
Capillus202	$$$$	5 months	2 year
Capillus272Pro	$$$$$	5 months	3 year

 
Product costing wise, the laser caps are among the most expensive laser hair growth systems – mainly because they are equipped with the highest amount of lasers (eg. 272 lasers) that are significantly more than the other laser helmets (eg. 51 lasers/LEDs) for better treatment effectiveness and greater coverage, as reviewed earlier.

Capillus laser cap devices offer 5 months money back guarantee, alongside 2 years (Capillus202) to 3 years (CapillusPro) of warranty period. This is more favorable compared to illumiflow laser cap that offers 30 days period of money back guarantee and 1 year warranty.
