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
CapillusPro272650 nm
illumiflow272650 nm
Hairmax Laserband82655 nm
Theradome80678 nm
iRestore51650 nm
iGrow51655 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.

Editorial Pick: WINNER of Treatment Effectiveness and Coverage

Capillus laser cap is FDA-cleared for hair loss treatment, it offers the highest number of lasers when compared vs the other LLLT hair growth device brands.

Operating at the optimized 650 nm laser wavelength, CapillusPro (formerly known as Capillus272) contains 272 lasers while Capillus202 model has 202 lasers to cover the whole scalp.
Indeed, illumiflow laser cap and HairMax ReGrowMD Laser 272 Laser Cap are other similar LLLT hair regrowth devices that offer 272 laser diodes at relatively lower price than Capillus.

These alternative FDA-cleared laser caps also deliver the clinically proven 650nm wavelengths of low-level light beams to stimulate hair growth.


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.

Treatment Instruction
Average Time per Day
Hairmax Laserband90 seconds x 3 times a week~0.7 minutes
Theradome20 minutes x 2 times a week~5.7 minutes
CapillusPro6 minutes x 7 times a week~6 minutes
iRestore25 minutes x Every other day~14.3 minutes
illumiflow30 minutes x Every other day~17.1 minutes
iGrow30 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.

Editorial Pick: WINNER of Treatment Frequency / Time Needed Per Day

Theradome LH80 PRO hair growth helmet is used for 20 minutes a day, two times in a week.

While this is translated to about only 5.7 minutes of treatment time daily, the required treatment frequency of 2 times per week gives its user certain flexibility in term of scheduling because not everyone can commit to use the laser hair growth system faithfully in daily basis due to their busy life style.

Theradome promotes healthier hair in the first 1-3 months of usage, with the user should see hair growth after 6 months.

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.
