Theradome Review: Is It Really Worth It?

By HighYa Editorial Team

Updated on: May 24, 2019

If you’re one of the 80 million men and women in the U.S. who suffers from hair loss, Theradome is a laser-powered helmet that claims to help grow new hair, increase the size of your hair follicles, and to slow—or even stop—hair loss. In fact, the company claims that.

The company features two different levels of hair restoration helmets, with one using more lasers than the other, a distinction we’ll discuss in a few minutes.

According to a document provided to HighYa, the treatment is effective enough to where four out of five hair loss professionals recommend the treatment.

The company is based in the Bay Area and claims to be the first company to produce an FDA-cleared, wearable laser hair therapy device you can use at home.

In our review, we’ll talk to you about how Theradome works, the effectiveness of laser hair therapy, what the device costs, what customers say about it and how it compares to similar products.

How Theradome Works

At its most basic, Theradome is a laser treatment intended to be worn on the head that the company claims has been developed over 5 years of research by biomedical engineers and doctors.

The company offers two helmets. The PRO LH80 requires two 20-minute sessions per week and uses 80 medical-grade lasers, whereas the EVO LH40 requires four 20-minute sessions per week with 40 medical-grade lasers.

The Theradome helmet weighs less than 16 ounces and is claimed to fit 98 percent of the population, but provides the same power, light level, and concentration as in-clinic lasers in the comfort of your own home.

Theradome’s proprietary lasers emit a very specific wavelength of light, remain cool when used, and are controlled through microprocessor algorithms. The company says their lasers contain more energy (joules) than any other laser light therapy and have a narrower beam for deeper penetration.

In addition, Theradome’s proprietary lasers emit a very specific wavelength of light (680nm) that has been shown to be ideal for clinical strength rejuvenation, remain cool when used, and are controlled through microprocessor algorithms. These lasers penetrate 5 millimeters, which is about the length of the average hair follicle.

Theradome claims that the helmet increases blood flow to the scalp and hair follicles, stimulates protein synthesis and cellular metabolism and promotes thickness and density. With this in mind, the helmet is claimed to result in three primary benefits:

  1. Grows new hair.
  2. Doubles the follicle diameter of existing hair (reverses miniaturization).
  3. Slows (and even stops) hair loss.

If used as directed, Theradome claims to halt hair loss within 18 to 26 weeks, to regrow hair within 28 to 52 weeks, and to provide fuller, thicker hair after 100 weeks.

Theradome features soft rubber pegs and foam pads for comfort, as well as a built-in speaker, while the automated treatment counting system keeps track of the total number of treatments you’ve undergone.

Theradome is claimed to result in zero side effects, and that it can be used with most hair-loss medications, and 30 days after surgical hair loss treatment.

Do Lasers Really Help Your Hair Grow?

We reached out to medical experts to get unbiased opinions about how effective these types of lasers are in helping hair grow.

Researcher John Satino, an expert with a long history in researching the benefits of laser light therapy, told us that this type of treatment is effective in helping your existing hair grow.

“However, this is no magic bullet. Nothing can grow back hair in a totally bald area only a hair transplant can do that,” he said. “I recommend the laser for patients with thinning hair, or first stages of loss. (Also), it works better with Rogaine and finasteride”

Dr. Dan Danyo, the owner of NA Hair Restoration, said that light therapy does indeed help with thinning hair but that it’s most effective for certain people.

“Research points to efficacy for improvement in the number/ density of follicles, the thickness of individual hair shaft diameter, and restoration of dormant follicles into an active growth phase,” Danyo said. “Laser light therapy is not likely to be useful in individuals with long-term and progressive balding.”

He also pointed out that laser therapy may not be an option for those who have dealt with skin cancer.

Pricing and Refund Policy

The Theradome PRO LH80 is currently priced at $895, and the Theradome EVO LH40 is $595. Both include free shipping. With your order, you’ll receive one Theradome laser helmet, AC charger, foam pads, and a protection bag.

Theradome comes with a six-month money-back guarantee, which begins from the date the helmet is delivered. However, this guarantee only applies to U.S. customers. All international orders are considered final. Details and requirements for processing returns can be found in the FAQ section of Theradome’s website.

Theradome hair loss helmets come with a one-year manufacturer’s warranty against defects in workmanship, although you can purchase an extended three-year warranty if you choose.

What Other Consumers Have to Say

At the time of publishing, HighYa and Amazon were home to numerous Theradome reviews.

At the time of publishing, the product had 36 reviews on HighYa with an average rating of 3.2 stars and 58 percent of users would recommend it to a friend. The most common complaints we saw were that the helmet didn’t work.

On Amazon, there were 47 reviews that gave Theradome’s PRO LH80 an average rating of 3.6 stars. Recent reviews of the product were mixed, with several people saying that the helmet worked and some saying it didn’t.

In general, we believe that whether or not Theradome works for you has a lot to do with your own specific hair health and how many of your follicles are dormant and how many are dead. As Theradome states, their product works only on follicles that are dormant and not ones that have died. In other words, it works with the existing hair you have.

The Bottom Line

As the experts with whom we corresponded pointed out, laser hair therapy is proven to help thicken existing hair and activate dormant hair follicles.

However, they also pointed out that the product won’t work for areas that are already bald. Also, one of the experts noted that laser hair therapy may not be effective for those who’ve had “long-term and progressive balding.”

In that context, we believe that Theradome could be an effective hair therapy tool for the right person. For example, one HighYa reviewer said that the helmet produced results within 90 days and that it was welcomed alternative to pills or spray-on hair therapy.

Keep in mind, though, that customer reviews indicate the device’s effectiveness is really polarizing. The majority of reviews were either five stars or one star, which means the helmet seems like there isn’t much middle ground. Either it works well, or it doesn’t, the general review consensus seems to say.

As a parting bit of advice, we think the insight one of our experts provided is helpful. You may want to try Theradome with a combination of Rogaine and finasteride.

Love my Theradome!

By Susan R., Auburn, CA, Verified Reviewer

Before discovering Theradome, I went and bought a wig because my hair was thinning so badly on top. But now I've been using the Theradome for 2 years faithfully for 20 minutes 4 times a week and I don't have to resort to my wig at all! I'm so glad I discovered this wonderful, easy-to-use product!

Hope for hair loss!

By Dee A., Washington DC, Verified Reviewer

My thin, fine hair was threatening to give away my age as it continued to thin out and recede over the years. In desperation, I begged my dermatologist for a solution, and she recommended Thermadome. It totally works! My husband stopped teasing me about my “ET helmet” as he began to notice my hair improve and my smile return. Used regularly it makes a noticeable difference. I pack it up and take it everywhere.

It has been a miracle for me

By Mela R., Alberta, Canada, Verified Reviewer

I have been using Theradome for about 3 years (332 treatments so far). I use it twice a week and also use Rogaine every day. I started seeing results about 3 or 4 months after starting to use it. Since then, my hair has stopped falling and has grown stronger and denser. It's healthy and shiny. My husband is amazed at the difference. Me too. I highly recommend it.

A gift from heaven

By Dominique M., Toulouse, France, Verified Reviewer

I was a lucky woman due to my special hair — very very fine and blond hair.

What was a young advantage has become a real problem in my life. Because the hair was falling out, and very quickly it was noticed due to my poor hair density.

Fortunately, one of my friends was one of the first Theradome sales representatives in France. We trusted it because there was urgency.

Intense use at the start, then weekly maintenance means that after 8 years later, at 66 years old, I am reassured having found normal hair. Even more, because the natural color has remained incredibly original (no white hair). Very spectacular for a grandmother

In conclusion, Teradome has become a daily tool as essential as my toothbrush.

Length of Use: 2+ years

Bottom Line: Yes, I would recommend this to a friend

Grateful for Theradome!

By Eileen H., The Woodlands, TX, Verified Reviewer

I noticed my hair was thinning over the course of a few years. I assumed there was no treatment. I learned of the Theradome from my doctor and I was evaluated and found to have hair follicles. The Theradome was a recommended treatment and after using it for several years I can say it is effective in promoting hair growth and decreasing the hair loss I was experiencing. I highly recommended this product. Hair growth occurs soon after beginning treatment but I did not want to write a review until I had confidence in it and could share a true well-documented review. I write very few reviews but this product is very important to me and has helped me avoid the disappointment and embarrassment of hair loss.

Length of Use: 2+ years

Bottom Line: Yes, I would recommend this to a friend

My Theradome Pro works again!

By Diana K., Boston, MA, Verified Reviewer

Lori was a wonderful guide for figuring out what was wrong with my device and working to get it back online again. She was patient, resourceful, and kind. She stayed with me until the problem was resolved and it did take some time. I know she was helping other people at the same time, but she certainly gave me and my Theradome Pro the attention we needed. I love my device and have seen results in more hair growth and stronger hair with less hair loss. Thank you Theradome and thank you Lori.

Length of Use: 1–2 years

Bottom Line: Yes, I would recommend this to a friend

Pros and Cons

I am able to connect and get help when needed

The device works

Their commitment to helping people restore their hair loss, which is a terrible problem for a woman
