iRestore Elite Laser
New iRestore Elite laser device for hair growth.

In my post on the best laser hair growth devices, one of the products I covered was the iRestore laser helmet from Freedom Laser Therapy. Until 2023, the company made two devices that they call laser hair growth systems. Sometimes they also use the terms “laser cap” and “laser helmet”.

  • The iRestore Essential with 120 lasers and LEDs (light-emitting diodes). Current average rating of 3.9 out of 5 stars across 3,800 reviews on Amazon. On sale for $500 after $100 coupon.
  • The iRestore Pro with 282 diodes (both laser and LED). Current average rating of 4.2 out of 5 stars across 940 reviews on Amazon. On sale for $800.

iRestore Elite Laser Helmet with 500 Diodes

In 2023, Freedom Laser released the newest iRestore Elite model with a huge 500 combined laser and LED diodes. The white color of prior models has been replaced by a sleep black appearance.

This device is FDA cleared for home use for hair regrowth purposes.

According to the company’s website, the iRestore Elite comes with the following features and advantages

  • 500 diodes (Lasers & LEDs). The most in any home-use laser hair growth device on the market. I have not tried to verify this claim.
  • 2500 mW total power output.
  • Brief daily 12-minute treatment time.
  • Unique triple wavelength red light technology (625/655/680 nm) for deeper scalp stimulation. Make sure to read my post on low-level laser therapy (LLLT) and wavelength.
  • Proprietary Lumitech™ red light therapy.
  • Advanced vertical-cavity surface-emitting lasers (VCSELs).
  • A patented extended scalp coverage for maximum effectiveness. It stimulates hair follicles in the temples, crown and hairline regions of the scalp.

The lasers are medical-grade VCSEL with a wavelength of 680 nm. The LEDs are medical-grade with wavelengths fo 625 nm and 655 nm. Kevin Chen, the president of iRestore, says that the Elite is the most powerful hair growth device for home use. It is sometimes called the “Ferrari of Hair Growth Devices.”

The iRestore Elite device can be purchased for $1,900 after a $600 off discount offer with a promo code. You can also buy a rechargeable battery pack that is on sale at $89. A 3-year warranty is included, and it can be extended to 5 years for an additional fee.

What’s Included

The hands-free helmet (not cap) itself has a ventilated design with adjustable soft foam pads so as to fit every head size perfectly. IT weight only 1.2 lbs.

  1. The iRestore Elite device.
  2. A universal power adaptor.
  3. A controller with timer display.
  4. User manual.

The Theradome Laser Helmet for Hair Growth

Theradome PRO LH80 Laser Helmet

You can purchase the wireless Theradome PRO LH80 laser helmet for hair growth from Amazon after reading the customer reviews.

Also available is the cheaper Theradome EVO LH40. Both devices have a 4.1 out of 5 star rating, though the PRO LH80 is far more popular than the EVO LH40.

A 2020 study of a helmet-like low-level light therapy (LLLT) device used in balding South Koreans, there was a significant increase in both hair density and hair thickness after 16 weeks of use. The 30  participants who got treated with the laser helmet saw an average increase in hair density of 41.90  hairs/cm2 and an average inrease in hair thickness of 7.50 μm.

Theradome Laser Helmet

Among the various laser hair growth devices and systems, the Theradome helmet stands out for its unique appearance. Other well known laser helmets include the iRestore and iGrow. On this blog, I interviewed this product’s inventor Dr. Tamim Hamid in 2015.

Since the HairMax Lasercomb first became popular a decade ago, a number of new laser products and contraptions have entered the market. Among these include the Revian Red cap for hair growth.

The Theradome (released in 2013) was the first one that received as much publicity. As of 2020, they now have two models that are discussed further below. More product details and historical information can be seen on the FAQ page on the company website. Also see their Instagram page and their Facebook page for regular updates.

Low-Level Laser Hair Growth Popularity

What really strikes me about low-level laser therapy (LLLT) is that so many people are willing to splurge for these devices. The proven benefits of LLLT when it comes to hair growth are limited. Even today, there are disputes about the appropriate wavelength of low-level laser devices.

Theradome raised close to half a million dollars via crowdfunding on Indiegogo in 2013. Quite surprising, considering that it was a new device with few ratings and reviews at the time. On the campaign home page, you can see a tab for number of founders, and the total is 1,266. The vast majority of those names are “anonymous” with no country of origin displayed.

All the people who bid $395 in the campaign were given the laser helmet in return. The campaign’s initial funding goal was $50,000, which I thought as somewhat optimistic. Perhaps my opinion is clouded by seeing the weak results of numerous other kickstarter crowdfunding campaigns.

Theradome EVO LH40 vs. PRO LH80

As of 2024, there are two models of the Theradome available for purchase:

  1. Theradome PRO LH80 with 80 diodes. Priced at around $900. Use for 20 minutes per day, twice a week.
  2. Theradome EVO LH40 with 40 diodes. Price usually around $600. Use for 20 minutes per day, four times a week.

Reviews and Ratings

The Theradome PRO LH80 currently has 350 reviews on Amazon, averaging 4.1 out of 5 stars. The Theradome EVO LH40 has 96 reviews, also averaging 4.1 out of 5 stars. Clinical trials for the PRO LH80 were completed in December 2016. On Trustpilot, the average rating is an excellent 4.8/5 stars. You can also purchase these laser helmets from Costco.

Theradome FDA Clearance

The Theradome laser is advertised as being the “First and Only FDA OTC Cleared Clinical Strength Laser Hair Therapy for Home Use”. It has been given FDA 510(k) clearance and is not likely to result in any serious side effects with correct use. The device comes with a 1-year warranty, and you can order replacement parts and batteries from the manufacturer.
