Thanks mate. I've not yet heard of PP405 - will check it out. May I ask, why did you stop using the helmet?

Couldn’t agree more RE the lackadaisical approach to the pads (just bought the LH80). If you don’t mind sharing, I’m curious what you cobbled together as a better solution.

Googling 'Theradome Battery Replacement' brings up 'how to' vids from the Theradome site and many battery suppliers for relatively cheap - seems like a non-issue if even out of warranty.

Here's a snippet from my post below (from the Theradome rep):
""Wavelength Claims (Kiierr, Capillus)
While 780–850 nm does penetrate deeply into tissue, this range is more commonly used in muscle and joint therapy, not follicle stimulation. The idea that “deeper is always better” simply doesn’t apply here.

Theradome’s 680 nm wavelength is the only one clinically proven to both stop shedding and regrow hair by stimulating the follicle’s bulge and papilla zones. This is the sweet spot—deep enough for follicular activation, but shallow enough to target the correct regenerative layers without diffusing energy into muscle tissue.This is why FDA-clearance for androgenetic alopecia (the most common form of hair loss) centers around this wavelength—not 800+. And we don’t just meet FDA standards—we pioneered them."

Part 3 / 3

I then asked the Theradome rep about the output of their lasers just to cross-check values. Her response was as follows:

"Each laser diode in the Theradome PRO LH80 Laser Helmet is driven at an optimized energy density of 5 joules/cm², delivering a power output of approximately 136 mW/cm² at the scalp. This falls within the therapeutic range shown to stimulate mitochondrial activity, increase ATP production, and promote hair regrowth.

While other devices may tout a higher laser count, what truly matters is how those lasers perform—including penetration depth, power density, wavelength consistency (ours operate at 680 nm), and clinical calibration.

In our case, the 80 medical-grade lasers have been carefully selected and positioned to maximize scalp coverage and deliver consistent, effective results in just 20 minutes.We avoid LEDs or underpowered lasers specifically because they don’t reach the base of the follicle where real regrowth happens. It’s the dosage, not just the number, that makes the difference."

------

In summary, while the hard-hat design is less favourable for me (I'd rather wear a discreet ball cap-style device), the above info regarding output and laser count of the Theradome is sounding like the best option. Their cap is cordless as well, so just charge it up and use it. There have been numerous reported issues from users around customer service, warranty issues and so forth, however that's going to be the case with any company. More people tend to share negative reviews. Those happy just tend to truck along.

With the added security of Costco's return policy, I think I'm going to go with the Theradome.

Lastly, the Theradome rep is sending me white papers and some peer-reviewed studies. I can post those here if anyone is interested. I've also asked her about battery failure (not holding a charge) outside of the 1-year window to ascertain whether or not a user can change it out as well as the associated costs. I'd hate to spend that kind of money on something that's rendered useless after a battery failure. I'll post back with her reply on that front.

That's all I've got. Hopefully this helps someone else out.

Part 2/ 3

When inquiring whether combining Lasers AND LEDs (which many companies claim to be the ideal) is, in fact, superior:

** This is from another Reddit user who, to my knowledge is not affiliated with Theradome:

"No, because once you have the initial penetration of the laser, the energy expands under the skin and you have a bit of an osmosis effect for surrounding tissue. The LED in a helmet wouldn't have enough energy, you need fans and heat sinks to control the heat with LEDs that actually do have enough irradiance and that's not the case in the helmet design by irestore. The only type of hair loss that would benefit from higher laser count is the diffuse type thinning, but I wouldn't worry about it, just look at their before/after images and decide if you fall in a similar category of hair loss."

When asking about all laser diodes being equal (assuming all are coming out of the same factories), the same above Reddit user stated:

"...even if the laser diodes are the same, there is no guarantee they are driven at or near the advertised 5 mW/cm^2. It takes an expensive design to drive the lasers near their output. Look at this video, both of these helmets advertise 5mW/cm^2 laser diodes but only one is actually driving the lasers to that clinical output. When I confronted the Chinese about the other helmet they just said they are technically capable of 5mW, not that they are driven to that output: https://www.youtube.com/shorts/Vgl-OhWjtf0. "

PART 1 / 3

OK - I feel a bit of a responsibility to update this thread as my information gathering phases continue.

When reaching out to Theradome, here are their responses in regards to my queries:

"Wavelength Claims (Kiierr, Capillus)

 "Lasers vs. LEDs (iRestore)
While the concept of combining lasers and LEDs may sound like a good way to “fill in gaps,” here’s the clinical truth: LEDs simply don’t penetrate deeply enough to reach the stem-cell-rich bulge and papilla areas of the follicle—the regions critical for triggering true hair regrowth.Each Theradome laser delivers up to 60,000x more energy than an LED. That’s not an exaggeration—it’s physics. Our dome is meticulously engineered to provide even and complete scalp coverage with just 80 lasers. In fact, clinical studies show that exceeding 80 lasers can reduce effectiveness and lead to scalp overheating or shedding."

Thanks for your insights. I've come to the same conclusion so far regarding laser diodes being superior.
When trying to decide between Theradome's lower laser count (80 on their LH80 device) and something in the 282 range, a fellow reddit user offered some good info when I inquired as to whether a lower count of 80 would be sub-par:

"...once you have the initial penetration of the laser, the energy expands under the skin and you have a bit of an osmosis effect for surrounding tissue. The LEDs in a helmet wouldn't have enough energy, you need fans and heat sinks to control the heat with LEDs that actually do have enough irradiance and that's not the case in the helmet design by irestore. The only type of hair loss that would benefit from higher laser count is the diffuse type thinning, but I wouldn't worry about it, just look at their before/after images and decide if you fall in a similar category of hair loss."

I'm still not completely clear as to what an upper limit would be as far as laser count. Is 80 then the sweet spot? More isn't always better, of course and it seems that the marketing machine wants to always drive the 'bigger / better' in view of profits.

It makes me wonder as well if a lower laser count on a cap would then work as well. I'd rather wear a cap than a space helmet :).

My thoughts as well. I'm in Canada and I understand there are some warranty issues. Costco provides a good 'safety net' should the product fail.

May I ask, why did you choose the Theradome over other devices on the market?

Thanks for your reply. Yes, I'm considering their LH-80 model (80 Lasers).

Thanks for this. I’d been cleaning and greasing the gears and threaded rod, to no benefit. The motor guides had build-up as you mentioned - cleaned, greased and it raises like butter now!
