## Description

desertcart.com : Theradome EVO Laser Hair Growth Helmet LH40 – 100% Laser, No Ineffective LEDs – FDA-Cleared Red Light Therapy for Hair Regrowth 4x Week – Made in the USA : Beauty & Personal Care

Review: Quality Product. Realistic Expectations... Consistant use has brought great results. - March 2018: Arrived on time, comes with sturdy carry case. Unit is well made. Easy to use, just charge the Li-ion battery and press the button to start. It talks to you, but it's not annoying, 'Ready for treatment, place on head', ...'Five minutes remaining', ...'Treatment No. 2 completed.' If you take it off your head during treatment the lights go out. With it back on the head the lights come back on, and she says, “Treatment resumed.” It shuts off after 20 minutes. Overall very good design. No discomfort. My wife is using it also. I plan to start with one treatment per day, five times a week, M to F. If any negative results, will reduce to three treatments a week, M-W-F. The instructions say to use it at least twice a week, and allow a full 24 hours between treatments. I expect to see some improvement in existing hair strength after two months, 50 treatments. I expect to see new hair re-growth after 12 months, 260 treatments. I am 58 years old, and get my hair cut about once every ten weeks,... so not much happening up there in one month. April 2018: I plan to update this review each month with progress, if any. May 2018 update: It's working. Using six days a week. After 42 treatments I see stronger hair, the wavyness is coming back, and small new hairs coming in. I have a small red birth mark on my upper forehead, my hair line was well above this mark,, now I see fine hair next to and in front of it again,... the birth mark is not moving up my head! The hair line is moving back down. Increased to 5 stars. February 2019 Update. We continue to achieve great results. More thicker stronger curlier hair. The hairs that come back are the same color and texture as before. For several years [from about age 54 to 57] I was going about ten weeks between haircuts. Last year I after I started using the Theadome red laser hemit I got my hair cut every six weeks. Now, after nearly a year of treatment, I get my hair cut every three weeks, as I did when I was in my thirties,, the computer at GreatClips is keeping track. The lady at GreatClips can easily see the difference and told me, “Just keep doing exactly whatever you are doing.” The customer service at Theradome is excellent. The company stands behind their products. Dec 2022 Update. Still going strong after 1017 treatments. The battery was easy to replace. We were traveling over seas for a while and when my wife, 74 years old, got back to her regular hair dresser she screamed, “Oh my goodness! Honey, where did you get all this hair?!” Nov 2023 Update. The battery charger finally quit. Everything is still working, but the helmet can’t charge the battery. Theradome sent me a replacement battery and power adapter for free; when that didn’t fix it they offered me a replacement helmet at a 25% discount and free extended warranty. Determined to make it work, I dug the little circuit board out of the end of the battery, bought a battery holder, battery charger, and several new 18650 rechargeable batteries from Batteries Plus. I twisted the wires together, plugged it back in, stuck the battery holder to the helmet with double-stick tape,… “Ready for Treatment, Place on Head.” It’s not pretty, but it works. About once a week, I need to pull out the battery and swap it with the one in the charger. The reason there are three wires for the battery is the over-temperature alarm; when you hear the helmet say, “Error, Temperature High,” I believe she’s referring to the battery. Some cheap Chinese batteries don’t have over-temperature protection, even though there are three wires, the battery is telling the helmet everything is Ok even when it’s getting close to thermal run-away. Always buy Theradome replacement batteries. You could save $20 on a cheap battery, but your helmet could catch fire. Lithium-Ion batteries can be very dangerous. For my external battery setup, the charger on my nightstand has over-temperature protection built in.
Review: Great Results and Outstanding Support - I started using the Theradome helmet after experiencing hair shedding from a prescription treatment, and it’s been a game-changer. The helmet is comfortable, easy to use, and feels well made. I’ve already noticed my hair feeling stronger and healthier. When I had questions, the support team was incredibly helpful and responsive. Overall, I’m really happy with both the product and the company’s customer care.

## Questions & Answers

**Q: I feel like the lasers are hitting the same spots with each use.  is that ok, or should i shift the helmet a little with each use? (model evo lh40)**
A: Actually, each time you wear the Theradome the lasers are hitting slightly different parts of your scalp.  But the way lasers work, once they hit the scalp, each laser beam spreads out, similar to water hitting a sponge,  so it absorbs then scatters.  Therefore you do not have to worry about trying to move the Theradome around to try to hit all spots on your scalp.  After 20 minutes all the lasers light will have spread around fully around your scalp as well as penetrated deep within your scalp to hit the hair follicles.  Hope this helps.  Theradome Support Team

**Q: Is there a way to turn off the speaker?**
A: Thanks for your question! Please press the master switch to turn the helmet on. Then double click the master switch to adjust the volume. The word “Theradome” will be spoken at your chosen volume level. You may double click the switch to lower the settings, which will decrease from loud, medium, soft, and silent before looping back to loud.

**Q: Are the hard spikes supposed to poke into my scalp when I use it? Or should I be using the enclosed pad to have it lifted more off my head?**
A: Si

**Q: Can the battery be replaced myself if it dies or will it have to be returned to manufacturer for battery replacement?**
A: Changing the battery is straight forward and you don't need to send your helmet back to us to replace. We have simple instructions and a video if you prefer to go through how to replace.

### ⭐⭐⭐⭐⭐ Immediately register the helmet with Theradome
*by C***C on October 22, 2025*

Still early in treatments but hair loss seems to have lessened. Looking forward to see what happens after a few months. Only problem so far was the power cord failed after 21 sessions. Stephanie at customer support was really great helping us get a new cord and then following up with to ensure all was working properly. She truly went the extra mile for us. Note…to overstate the obvious, be sure to immediately go on Theradome’s website after it arrives and register the helmet.
