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.

For more information, see the manufacturer’s Youtube channel and Twitter.

CurrentBody LED Hair Regrowth Device

I have covered a number of popular laser hair growth devices on this site in the past. Including the LaserComb and Theradome.

While the vast majority of these devices make use of laser diode light, a new FDA-cleared product called CurrentBody LED hair regrowth device uses only light-emitting diode (LED) light.

LLLT and Hair Growth

In general, readers are skeptical about the hair growth benefits of wave based treatments such as low level light therapy (LLLT) and sound therapy for hair loss.

However, LLLT continues to be covered at every single major hair loss conference. Moreover, new studies keep coming out that tout the benefits of light energy and photobiomodulation (PBM) on scalp hair growth and quality. Including a 2021 one from L’Oreal that found LLLT to downregulate scalp inflammatory biomarkers in men with androgenetic alopecia.

Among the things that laser light can do for scalp health and hair quality include:

  • Stimulate the mitochondria via photon absorption.
  • Reduce inflammation and improve circulation.
  • Increase synthesis and production of adenosine triphosphate (ATP).
  • Increase nitric oxide (NO) synthesis.
  • Impact gene expression in a number of ways.

CurrentBody LED Hair Regrowth Device

The CurrentBody LED hair regrowth helmet device makes use of 120 red LED bulbs that deliver full scalp coverage. The average power of 18 J/cm² compared to an industry average of 6 J/cm² makes this device three times stronger than other devices on the market. It can be used by both men and women suffering from hair loss.

Note that LED diodes are nowadays much stronger than in the past when it comes to wattage output. They can even power car headlights. Historically, laser diodes were always preferred to LED diodes when it comes to LLLT devices. However, this is no longer true due to technological advancements in LED technology. Laser phototherapy (LPT) devices only use laser diodes.

The wavelength of the red light from this device is 640 nm. See my past post on laser therapy for hair loss and wavelength. Red light wavelength ranges from 400 nm to 700 nm.

The device comes in two sizes:

  1. Small/Medium (Head Measurements: 54cm – 58.7cm).
  2. Medium/Large (Head Measurements: 59.7cm – 63.5cm).

It is charged via a USB cord (but no mains plug is provided). You need to use the device for 10 minutes per day for 16 weeks for visible results. The device won “Best New Product” in the “Tools” category for the Marie Claire 2023 Hair Awards. It was also featured on the UK show “This Morning” as one of Nadine Baggott’s top products to beat hair loss.

The company sent me the below before and after image that shows a very good responder to this treatment. Note that this man is also using topical Minoxidil.

My Experiences with CurrentBody’s LED Device

I started using the CurrentBody LED hair regrowth device two days ago. I have never used any other laser device in my life. It was extremely easy to use the helmetlike machine right out of the box. It is also relatively lightweight when considering the large quantity of LEDs inside. Note that the device should never be used on wet hair per the user manual instructions.

After my first 10-minute treatment session, I got a slight burning smell, but I did not see any smoke or melted plastic anywhere! After my second treatment, I got a milder burning smell, but it could also be from my shirt as I had been to a bar earlier. No obvious difference in hair texture in just two days of use.

The 120 LED lights make this product look very futuristic. I used it for 10 minutes and it then shut itself off automatically based on an in-built timer.

Due to the short duration of treatment, I did not try to connect the headphones with my phone via bluetooth. That in-built option is available in case you want to listen to any music or podcasts during the 10 minutes of daily treatment.

I have not yet needed to recharge the device, but will probably try charging it via my computer USB port. If that does not work or is too slow, I will recharge via using a USB adaptor connected to an electric wall outlet.

Do note that I am also currently using 0.5 mg Dutasteride twice a week and 2.5 mg oral Minoxidil once per day for my hair loss. The oral Minoxidil seems to be working quite well and I only started using it in November 2022. I have been using the Dutasteride for a few years. So my results with the laser device could have some bias when I update this post in the future.
