Imagine watching your beautiful hair start to thin and then progress to falling out to the point of no return. Losing hair is certainly not the most exciting of experiences. However, it is a common condition, and it does have a cure


Alopecia (pattern baldness) is a common disorder affecting over half of the world’s population – both men and women. According to research, Androgenetic Alopecia (AGA) is the most common kind of alopecia, affecting up to 50% of men above 40 years and about 75% of women above 65 years.


In men, AGA is recognized by a receding front hairline and hair loss around the crown of the head. In women, the hair around the crown of the head begins to become notably thin. Alopecia also tends to result in lower self-confidence, especially in younger patients. 


Can androgenetic alopecia (pattern baldness) be cured?

Fortunately, there are methods for curing AGA. There are options for medications and prescriptions, and presently, the two approved drugs for this are minoxidil and finasteride. There are also hair transplants and laser treatments. Every day, new hair loss products, treatments, and quick fixes are surfacing on the market, but you need to be careful when choosing a treatment to avoid using fake or ineffective products. 


Several studies have shown that laser hair treatments result in fewer side effects and are a safe and more effective alternative to pills, solutions, and shampoos. More people are becoming open to the use of laser treatments for AGA as a great alternative to prescriptions for hair loss, which is why we have compiled the research for you in this article.


Keep reading for a detailed comparison of the top 5 laser caps to make the best decisions and get the most suitable solution for your AGA. We have compiled this comparison after considering functionality and effectiveness, safety, product quality, design, and price.

What is LLLT, and does it work?

Low-level light therapy (LLLT) is a technology that uses concentrated light emissions tuned to a particular frequency and wavelength to target skin cells and hair follicles. It is an efficient method of regrowing hair with LEDs. When the light emissions hit the hair follicles, it re-energizes them and speeds up their metabolic rates, helping them grow faster. The wavelength of the red light is very effective at 650nM.


Controlled clinical trials have been conducted and have shown that LLLT is indeed effective in stimulating hair growth. This treatment is non-invasive and does not cause any burning sensation, unlike other laser treatments, because it uses ‘cold’ lasers. 


One of the reasons why a lot of people are comfortable with LLLT is because these lasers can be used in the convenience of your home. There is no need to book a session in clinics, you can simply perform a diagnosis online, find out your peculiar condition, purchase the right laser cap and use it while adhering to instructions at your own convenience.  


How LLLT works to stop hair loss

The exact working mechanism of LLLT is not evidently fully known. However, exposure to the laser likely causes an increase in the flow of blood to the scalp. This increased blood provides additional nutrients to the follicles of the hair and strengthens them, helping them grow rapidly. 



An evidence-based review has shown that LLLT is a safe and effective procedure. The reviews have shown that these lasers can cure both female and male hair loss, and it’s been discovered that it is easier to treat moderate-level hair loss than severe hair loss. This is why it is best to take note of your hair loss in time and start treating it as soon as you notice it – the earlier, the better. 


Can LLLT be combined with other chemical treatments?

So far, there have been no negative reports from combining LLLT with other hair growth solutions including prescription medication that’s topical or taken as a pill. Remember that the program is non-invasive and focuses on the scalp. In some cases, the combination of LLLT with other effective chemical and topical treatment emissions speeds up the rate of treatment. 


Are there dangers associated with using LLLT

LLLT is FDA-cleared – it is a safe and effective treatment, so you need not worry about side effects. 


However, some recommended safety guidelines should be implemented while using LLLT:


  1. If you are on any form of medication that makes your skin more sensitive to light, then you should avoid using LLLT. 
  2. When using the LLLT caps, avoid looking directly into the lasers. The light being emitted has substantial amounts of energy that is too sensitive for your eyes and can cause damage. 


Is LLLT worth it?

Yes, laser treatment might be expensive. However, because of its high level of effectiveness, most patients consider it worth the cost. Laser caps have extended life spans, and compared to most topical or oral treatments that you must continue to take over years and years, they are well worth it in the long run. 


Take finasteride or minoxidil, for example – they both need to be used for as long as you want to keep your hair, which can add up over time. If you stop taking them at any time, the hair you’ve regrown in any area will fall out just as fast as it grew in. With laser treatment, while you do have to continue use to keep your hair, you can drop to a maintenance schedule of once or twice a week after you get to a point where you’re satisfied with your regrowth.


Basically, you’re comparing a one-time purchase to a lifetime of monthly solution purchases. The worth might depend on the level of your hair loss and your budget. Some alternatives are cheaper, but many of these alternatives are not half as effective as laser treatment, and you might find yourself in need of another treatment after a short period. 



What are our top picks for laser caps in 2022?

There are numerous laser treatment products available, each having its unique design and efficiency. In the following sections, we will evaluate our best 5 laser caps for hair loss.



1. iRestore Pro

The iRestore Pro cap has undergone rigorous testing, and its durability has been confirmed. Clinically proven and dermatologist recommended, the iRestore Pro cap offers a 43.2% increase in hair count and is a non-invasive hair growth solution with the best scalp coverage on the market.


It has a shelf life of 5 years, so it’s safe to say that it’s worth its high cost. It has 282 medical-grade lasers and LEDs and an excellent full-scalp coverage encompassing the entire scalp, including the back and the sides. It functions effectively when placed on the head for 25 minutes, 3 days a week. 


It weighs 1.27lbs, and it has an AC adapter. The automatic shut-off, timers, and display present in its design give it a hands-free experience. Every iRestore Pro product undergoes a 24 hours “burn-in test” where it’s turned on and left for 24 hours. Only the products that make it through this stage are sent into the market. 



iRestore Pro is FDA-cleared, so you can feel rest assured of both its safety and its effectiveness. It’s known for the extreme comfort that it provides – with slits and cutouts on the sides and back to produce proper ventilation and soft foam pads on the insides of the cap for comfortability, you can leave it on your head for the duration necessary with full comfort. 


iRestore provides a 12-month money-back guarantee with the shipping fee covered if returned. The iRestore Pro costs $1195. However, there is a current discount that takes off a whopping $400, leaving the price at $795. This is one discount you don’t want to miss!


2. HairMax PowerFlex laser cap 202

The HairMax PowerFlex is another effective laser. It has 272 laser diodes, but no LEDs. The cap has full-top scalp coverage and can be placed on the head for about 15 to 30 minutes, 3 days a week, for effective functionality. 



The HairMax has a portable design, likening the cap to a normal baseball cap. This means that the outer part of the cap is made from fabric material, which is not as sturdy as other models. With a total energy output of 1360 mW, it comes with an AC adapter and a rechargeable battery pack so that you can use the cap on the go.


It has clinically proven technology, and it is also FDA-approved. The HairMax is $1899 and has a 6-months money-back guarantee (with a 20% restocking fee).


3. Kiierr 272 Premier

The Kiierr 272 Premier is an excellent laser cap. It has 272 laser diodes and no LEDs. It is FDA-approved and has a 2-year product warranty to make you feel safe about your purchase, along with a 7-month money-back guarantee.



Kiierr weighs 2.4 lbs and also has a baseball cap design, giving it a comfortable (but again, less study) fit. It has a very simple operation and a strong battery life that can take up to 5-7 sessions between charges. The treatment time is 30 minutes on alternating days. Kiierr is also very durable, lasting up to 15,000 hours in its lifetime.


At $875, the Kiierr 272 Premier is a cost-effective model if you’re in the market for a laser cap.


4. Theradome Pro

The Theradome Pro has full scalp coverage and is designed to be both portable and power-efficient. It is also FDA-approved and provides effortless and convenient hair growth. Designed with proprietary clinical strength cold therapy phototherapy, its lasers can supply up to 678 nM of laser light from the 80 lasers. 



Theradome Pro requires a treatment time of 20 minutes per week 3 to 4 times weekly, for effective results. The battery is durable and can conveniently carry up to nine 20-minute sessions before requiring a recharge. 


It has been clinically proven to restore hair growth, and there are several positive reviews about Theradome Pro. At $895, it is a bit expensive, but because of its proven effectiveness, it’s worth the price.


5. Capillus Pro

The Capillus Pro is a highly recommended laser cap that has been clinically proven to provide results. It has 272 lasers and total light energy output of 1360 mW. The unit comes with an AC adapter and is battery-powered, just like the other products.



It provides full scalp coverage and only needs to be placed on the head for 6 minutes daily. The outer part of the Capillus Pro cap is made from fabric, which does reduce its sturdiness, and there is no timer display to let the user know how much time is left for the session to be over. Although a small lapse that may seem inconsequential, this is a major reason for users’ preference for other products in its stead. 


The Capillus Pro costs $2999, making it the most expensive on this list, but its efficacy makes up for the price. It has a 12-months money guarantee (with a 25% restocking fee), along with a 3-year limited warranty.


How to use laser caps

The working principle of laser caps is quite simple. All you need to do is put on the cap and attach the pack to your waist. Press and hold the power button for a few seconds, and the device will be turned on. When the session for the treatment is over, turn off the device. Some of the caps are designed to automatically go off after the session time is elapsed.  



The Verdict: Which laser cap is best for hair regrowth?

These are our top picks when it comes to laser caps. Each of these products has its pros and cons. In our opinion, the iRestore Pro is the best laser hair cap on the market now as the most powerful model with many remarkable features, a durable design, and the most complete scalp coverage for your hair regrowth.

With the current discount of $795, you’re saving a major $400 from its original price, making it even more desirable right now. And, with a 12-month money-back guarantee, you’re making a choice that you can feel good about.
