There are many products on the market today aimed at restoring hair loss, from topical treatments to medications to hair transplants. Rather than opting for one of the traditional methods for hair growth, an amazingly effective and safe technology is now available to use in the comfort of your own home.

Low-level laser light therapy (LLLLT) used to only be accessible through clinics. Not only is it convenient, but it’s an amazing and effective hair loss treatment! 

Low-level light therapy has been scientifically proven to restore your hair follicles, giving them increased energy and blood flow. LLLT improves cellular respiration and stimulates your hair follicles, producing thicker and healthier hair.

So, if you have hair loss, whether it is severe or mild, low-level light therapy has the potential to help you in a truly significant way. Despite the fact that this technology is unfamiliar to some people, a lot of people are already using it with great results. 

Is Low-Level Light Therapy Safe? 

Many people wonder about the safety of using low-level light therapy. After all, shooting laser beams into their own head is not something that most people are accustomed to. 

But, the good news is that it is completely safe. In fact, there have been extensive scientific studies conducted by scientists, doctors, and medical researchers to thoroughly test the safety of using low-level light therapy for hair loss. 

Studies such as this one have concluded that LLLT is completely safe to use for the treatment of the scalp for hair loss. This study also demonstrated a 37% increase in hair growth for people who used LLLT compared to the placebo, proving the effectiveness of LLLT. 

So, essentially using LLLT laser caps for hair loss treatment is completely safe and is scientifically proven to get great results for hair growth. This makes it one of the most promising hair loss treatments available on the market. 

Comparing LLLT Products 

There are many LLLT products on the market all claiming to be the best ones to treat hair loss, but some of these laser hair caps are significantly better than others. 

Below, we’ll compare in-depth two laser cap companies, Kiierr vs. Illumiflow, to give you better insight and reveal the advantages of each brand. After reading this Kiierr vs. Illumiflow review, you should have a much better idea of which is the better company for LLLT-based hair growth. 

**Clinical research and studies like this have confirmed that Low-Level Light Therapy (LLLT) is safe and has been used in clinics for decades with wonderful results.

Comparing Kiierr vs. Illumiflow: Differences & Similarities

Illimiflow v. Kiierr image with all details


  1. Diodes. Kiierr and Illumiflow both use medical-grade laser diodes, not LEDs, which is beneficial for both products.
  2. LLLT. Both companies use low-level light therapy science for the best hair growth treatment possible.
  3. Automatic Shut Off. Both laser caps have programmed sensor technology to automatically turn off the cap. Therefore, you can keep the cap on, no matter what activity you’re busy with – including sleeping (it automatically turns off when you sleep).
  4. FDA-cleared. Devices like laser hair growth caps utilize laser components for medical treatment and are required to comply with safety regulations overseen by both the U.S. Food and Drug Administration (FDA) and the Center for Devices and Radiological Health (CDRH). When it comes to purchasing a medical device, it is vital to protect yourself and look for FDA clearance. Click here, for more information on FDA clearance.


  1. Guarantees. Kiierr offers a 7-month guarantee or your money back, while Illumiflow only offers a 6-month guarantee.
  2. Warranties. Kiierr gives a 2-year warranty with each cap, allowing you to feel protected with your purchase. They will send you a new unit, absolutely free, in case there happen to be any issues related to the cap. Illumiflow on the other hand has a 5-year warranty, and if any issues arise, they will send you a new one for the cost of shipping. So, although you don’t have to pay for the device in the case that it breaks down, you will still need to pay shipping for a malfunctioned device.
  3. Products. While both companies offer a 148 and 272 laser diode laser cap, Kiierr offers other hair growth supplements to assist in hair restoration. Such as DHT blocking shampoo, Biotin gummies, dermal restorative hair growth cream, a laser cap carrying case, and more.
  4. Return policies. Kiierr offers customers a 14-day window to return their laser cap upon receiving it. Whatever the reason may be, you are allowed to return your cap within the first 14-days for a small restocking fee. Illumiflow on the other hand allows no returns until the 6-month growth guarantee period is up.

Sizes. Illumiflow has a “one-size-fits-most” laser hair cap. While Kiierr offers two different sizes, regular and XL, for a more comfortable fit.

Testimonials: Kiierr Laser Cap

“After years of experimenting with several products (which almost always left me with a long price tag & short-term results). I decided to invest in the Kiierr Laser Cap: 272 Premier Model; not only is the battery life incredible (providing multiple treatments with ONE charge) but after only SIX months of continuous use there has been a remarkable improvement in the strength, structure, and integrity of my existing hair with noticeable growth in those previous ‘problem areas.” -Mark G.

Testimonials: IllumiFlow Laser Cap

“I’ve meticulously tracked my results for over a year now. At 6 months, I can’t say the visible results were what I was expecting, but I felt that my condition wasn’t getting worse, so I stuck with it. After a year, my current hair is definitely of better quality and some new growth in both the crown region and “widows” peak has become more prominent.” –Jeffrey H.
