You can purchase the wireless Theradome PRO LH80 laser helmet for hair growth from Amazon after reading the customer reviews. It is currently on sale for 10% off.
Also available is the cheaper Theradome EVO LH40. Both devices have a combined 4.3 out of 5 stars average rating as of December 2024, though the PRO LH80 is more popular than the EVO LH40 based on past separate breakouts.
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 increase in hair thickness of 7.50 μm. Also read this systemic review of 32 home-use LLLT devices that had been approved by the FDA as of January 2020.
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, their Facebook page and their Twitter/X 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:
- Theradome PRO LH80 with 80 diodes. Priced at around $900. Use for 20 minutes per day, twice a week.
- Theradome EVO LH40 with 40 diodes. Price usually around $600. Use for 20 minutes per day, four times a week.
Reviews and Ratings
In the recent past, the Theradome PRO LH80 had 350 reviews on Amazon, averaging 4.2 out of 5 stars. The Theradome EVO LH40 had about 100 reviews, also averaging 4.2 out of 5 stars. As of 2025, the reviews for the two devices have been combined. 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.
Clinical trials for the PRO LH80 were completed in December 2016.
