The best advanced laser helmet for hair loss treatment- Theradome Pro LH80 vs iRestore Professional

Which device is better for professional-grade hair loss treatment - Theradome Pro vs iRestore Professional

When it comes to our appearances, hair plays a major role. It also adds a great deal to our confidence levels. So, be it a moderate or severe hair loss problem, it automatically has a psychological impact on us. 

Like hair itself, ‘hair loss’ also has different types. For most of them, professional help is the way to go. However, it is not always possible to take time out from your busy schedules. It is no surprise that laser caps and laser helmets have thus become a go-to substitute for clinical hair restoration treatment (for hair regrowth for men and women). 

In this post, I’ve compared 2 FDA-cleared laser helmets- Theradome PRO LH80 vs iRestore Professional. Read on to know which of the two professional-grade LLLT treatments is a better pick to regrow your hair. 

I have compared these laser helmets on the following factors:

  • Technology
  • Power Output
  • Comfort
  • Portability & Convenience (Corded / Cordless)
  • Treatment Time
  • Cost, Return Policy & Warranty
  • Safety (FDA Clearance)
  • Brand’s Market Experience
  • Customer Reviews
Theradome Lh80-Vs-Irestore-professional

Theradome PRO LH80 Vs. iRestore Professional


Both hair regrowth devices work on LLLT (state-of-art) technology. For effective results, the light treatment has to reach the hair follicles and be administered consistently at a particular wavelength.

While Theradome Pro has 80 medical-grade proprietary lasers embedded inside the cap, iRestore Professional contains 82 lasers and 200 LEDs. Many studies have concluded that LEDs are not as powerful or efficient when it comes to penetrating the scalp and stimulating the follicles. 

Technology Winner: Theradome Pro LH80

Power Output

How would you determine the strength of these laser helmets? 

It is basically the sum of three things:

  • Power output, i.e., measured in mW
  • The wavelength (nm)
  • Number of lasers in the cap

On the one hand, iRestrore Professional generates 1410 mW at a 650 nm wavelength; on the other, Theradome Pro generates 727 joules at a wavelength of 680 nm (penetrates up to 5mm). 

Power Output winner: Theradome


Both helmets have a foam pad beneath the light layer to give them a snug fit. 

Portability & Convenience

Aside from the lack of time, why else would you use a laser helmet instead of going for an in-clinic experience? 

Flexibility has to be one of the reasons. 

You are probably looking for a hands-free LLLT treatment and both these brands offer that. However, when it comes to mobility, the best choice is a fully wireless device. It will keep the annoying tangles and the extra weight at bay, helping you move freely while a session is on. 

Theradome Pro LH80 is a U.S-made cordless laser helmet with an in-built rechargeable battery (lasts up to 9 sessions/ charge). No more excuses to miss work or run errands during hair regrowth treatment! 

It also has a 20-minute auto shut-off mechanism in place. This means you don’t need to keep a tap on the time when you use it and simultaneously ensure you receive the treatment for the required time. 

iRestore Professional- It is a corded hair loss treatment device. Since there are no rechargeable battery slots inside, you need to plug it into a power outlet during each session. 

This one has a built-in LCD display telling you the remaining time per session to pause and restart accordingly. 

Portability Winner & Convenience: Theradome

Treatment Time

Be it in following the regimen or power output; consistency plays a key role in determining the time taken by a laser device to reverse hair thinning issues. 

As per clinical studies and consumer use, it usually takes the first three months of use for hair thinning to stop; and the next three to show signs of new regrowing hair. This might not be the same for all because both timeline and results depend on how individual scalps respond to the treatment. 

Here’s the brand-recommended regimen:

  • Theradome Pro- 20 minutes session (twice a week). If used in less than 20 minutes, the optimal energy density may fall short of reaching the base of the follicles. Maximum participants of the clinical trial saw dynamic results in 8 weeks. 
  • iRestore Professional- 25 minutes session (every other day). Participants of their clinical trial have shown 40 percent hair regrowth in 4 months. 

Note: You get full-scalp coverage from both products.

Treatment Time Winner: Theradome

Cost, Return Policy & Warranty

LLLT treatment for hair loss is not an overnight process. As mentioned earlier, it takes a minimum of 6 months to start showing results. So, knowing about the warranty and return policy of these devices always comes in handy. 

Let’s see how Theradome Pro and iRestore Professional compare.

Theradome Pro

  • Price- $ 995 
  • Trial Period- 6 months money-back guarantee
  • Warranty- 1 year ($149 extra for extended warranty)

iRestore Professional

  • Price- $1,195 (Check price on Amazon)
  • Trial Period- 12 months (does not include restocking or return shipping charges)
  • Warranty- 1 year (additional charge for extended warranty)

Theradome’s warranty is auto-added to the official website purchases. If you buy from Amazon or other authorized sellers, visit to complete registration and avail of the product warranty. 

Note: The money-back guarantee of both is only for official website purchases. We are not sure about other stores. Be sure to check with them beforehand. 

Trial Period Winner: iRestore Professional

Warranty Winner: Tie


Both these laser helmets are FDA-cleared and are safe to use to fill your receding hairline. No harmful side effects have been reported after using this natural hair growth method. 

Market Experience

Time on the market matters when it comes to trusting a brand. The same goes for laser caps. The iRestore Hair Growth System was launched by Freedom Laser Therapy in 2003. Clearly, they’ve been in the business for quite some time now. 

Theradome, as a brand, is younger since they have been on the scene since 2014.

Time on the Market Winner: iRestore 

Customer Reviews

To save you time, I’ve gone through the customer feedback of the products from multiple platforms, including their official websites and Amazon. Here is what I found:

Theradome Pro- After combining ratings and reviews on major eCommerce platforms and review sites, it can be concluded that Theradome Pro LH80 has an overall 70.5% of positive reviews. 

iRestore Professional- Even though the iRestore 282 cap has only 82 lasers, the percentage of positive reviews on irestore is pretty high at 78%. Even one of my favorite travel vloggers, David’s Been Here, has reviewed this product with positive after-use results! 

Common Complaints:

  • iRestore works, but it has a longer recovery time and is not as portable. It does not come with a battery charger and has to be bought separately. 
  • Theradome Pro- No negative reviews as such.


This is a really tough choice to make for iRestore Vs Theradome since iRestore has a one-year trial period and has more positive ratings than Theradome. Theradome, on the other hand, uses only lasers, applies the maximum wavelength, and is the only device that claims to be effective on dark-skinned people. It is also used in clinics. For example, the Cleveland Clinic uses Theradome Pro to treat in-clinic patients suffering from hair loss. Therefore, I would choose Theradome Pro if I first choose a laser-based helmet for hair regrowth.  Also, it is more affordable than iRestore and comes with a money-back guarantee.
