Kiierr Review | Beware the Hype

While their product is FDA-Cleared, there’s got to be a red flag coming up in your mind when you hear that an entire laser cap business popped up overnight with the infrastructure necessary to properly conduct quality control and comply with the many regulations of the laser cap industry.

Other brands, including Kiierr have sprung up, leveraging illumiflow efforts, directly or indirectly, as the predicate for FDA clearance.

Here’s a simple timeline using data from the FDA records of when Kiierr FDA clearance was granted. Note that Kiierr was granted FDA clearance through a laser device which gained its FDA clearance from illumiflow, effectively making illumiflow the grandparent predicate device.

The takeaway here is that some laser device websites are not established companies and may be operated by internet marketers who chase profits first with quality control and support infrastructure a second thought.

Of course, this is just opinion, but the optics are NOT good, so it’s worth doing your research before buying online.

“Fast” isn’t good when it comes to start-up laser cap brands

Running a laser cap company is expensive by nature, requiring infrastructure to support a team who can tend to endless assessment of emerging and current technologies, science and health, and customer service, all while remaining compliant to regulations. Meanwhile, to some companies, FDA clearance is just another startup cost.

The most obvious signs that Kiierr is operated by internet marketers and not people who are passionate about hair loss:

When Kiierr first launched its website, they used misleading information to project the image of a longstanding company with a history of sales and support. Most such information has since been removed – after websites like this one called them out online. Here are a few examples, some of which can be seen by stepping back in time on websites like

  • They recently removed customer reviews on their website predating their FDA clearance.
  • The badges on their homepage for CNN, DATELINE, TODAY, The DOCTORs are misleading and link to the Kiierr product page, not to actual press information. Here’s the original website presentation from earlier in 2019:
Kiierr Laser Caps
No disclaimer here! (February 2019)

Later in 2019, they updated their website with a small disclosure reading “LLLT Has Been Featured In:” See the image below. It’s circled in red so you can see it.

This is a common internet marketing tactic.

Note the additional disclosure is in light gray text, intentionally hard to read, which basically says that they’re toeing the line, but this isn’t necessarily for the shopper consumption.

Note the new disclaimer… but the media icons still don’t link to relevant press information! (Current date)

Since their recent FDA clearance, they’ve flooded the internet with pop-ups and retargeting ads, a clear message of where time, energy, and money are being spent, marketing.

Kiierr basically copied content and concepts from other established brands websites.

See the examples below, listed oldest to newest.

Very similar, right?  This is not necessarily illegal or wrong in general, but it is very telling as to who set the standard in this industry and which brands are “fast-followers”.

While we can’t be sure what’s going on at Kiierr headquarters, in general when so much is spent on marketing in the early days of business, areas such as customer support, product safety or quality control can take a hit.

Established companies like illumiflow, Capillus, and iRestore (full iRestore review here) are safe bets for both quality, safety, and service, so if you’re buying your first laser cap, it might make the most sense to stick to these original brands who were built on a solid foundation.

Illumiflow (our #1 recommendation) is very open about taking FDA clearance seriously—you can read their blog post about it here.

  1. The advertisement says “no risk, money back guarantee 100%” It does not say, “if” There are several ifs. You will see the cap is not recommended for ALL patterns of hairloss. Mine is not covered. I tried to return the cap and had not registered even though they have records of my purchase. They will not take back their product. BEWARE !!!!!!

    • I’m really sorry to hear that happened to you with Kiierr, Cheryl.

      So they didn’t live up to their 7-month Money Back Growth Guarantee?

    • She is 100% accurate. I had the exact same experience. This company is a huge scam and their product does not work. FDA approval is meaningless. All that shows is the product won’t hurt your body. It won’t help your hair growth at all. There are so many IF’s on their return refund policy, they should be prosecuted as the biggest bait and switch companies around. SCAM SCAM SCAM

      • Hey Jeff,

        Thanks for sharing and I’m really sorry to hear you’ve had a bad experience with Kiierr. I do want to clarify that LLLT devices like this don’t have FDA approval but rather FDA clearance.

        That said, while we don’t have experience with using a Kiierr laser cap device personally (I use another brand myself) LLLT laser cap devices have been shown to help regrow hair.

        Depending on the individual and cause of hair loss though it may not be effective for everyone, which is why we recommend going with a company that has a good return policy, top-notch customer support (phone support), and an easy to use money-back guarantee like; illumiflow, Capillus or one of the one’s we talk about here.

  2. No results for me after a year of Kiierr cap use. I used the cap judiciously for a full year and saw little to no results, in fact I think my hair loss got worse during that time. The first 3 months I also took the Kiierr supplements. After 6 months my cap stopped functioning, and they replaced both the cap and battery pack. I mistakenly thought that the “guarantee” for hair growth required a year of use (rather than 7 months), and so attempted to get a refund after a year but was told I had missed my chance. If you want to use their “guarantee”, be sure to read all of the requirements when you first get your cap. You need date-stamped pictures both at the beginning and end of the 7 month period and have to register your purchase within 45 days of purchase.

    • Bill, thanks for sharing your experience with using the Kiierr supplements and laser cap. It’s these kinds of Kiierr reviews that help others who want to regrow their hair know what may or may not help them.

      Also, thanks for letting others know the hoops they have to jump through or the steps they need to have in place so they can even get a refund should the product not work out for them.

  3. I purchased a Kiierr cap and when it arrived I found it would not come close to fitting my size 7 1/2 head. I contacted Kiierr, received a return authorization, and immediately returned it. Other than the cap nothing in the original packaging was touched. When I asked for a refund based on an unusable product I was told that there was a 20% restocking charge. I questioned this based on the “100% satisfaction guarantee.” I was told that this only applied if I kept and tried their product for seven months. Buyer beware! In my opinion there should be NO restocking charge for a product that was not usable from day one.

    • Hey Bruce, thank you for letting us know your review of Kiierr.

      I can imagine that was quite frustrating and seems like a pretty high restocking fee if you ask me.

      I appreciate you sharing so others know.

    • I had the exact same thing happen, the cap would not work properly as it was no where near the proper size. When I contacted Kiieer they told me that they had a better, newer version that would fit for an additonal $300+ cost. I never even used the cap an was withing 5 days of purchase and delivery. I told them I did not want to pay more for a cap that would fit and work and they said I could return it with a 20% restocking fee. Stay away from Kiierr, their customer service sucks! They are only about making money.

      • Hey Russ, we appreciate you sharing your Kiierr review and experience. I’m really sorry to hear that you had this experience as I can imagine how frustrating it is to invest a significant amount into a product to assist with hair loss or hair regrowth only to find out you are actually unable to use the product.

        I’m not really sure why they wouldn’t be willing to just work with you to get this sorted out in a more reasonable manner but it seems like the customer service is offered mostly via email. Is that right? Or were you able to speak to someone?

        I know others here who bought Kiierr products before needed to communicate via email as that’s what their ‘return policy’ page stated.

  4. Someone here must have it in for Kiierr laser caps. I’m trying one myself but I don’t think I can slam it until I know if it’s good or bad first. You are supposed to use this for 7 months before deciding whether to return it or not and it doesn’t seem to be any different than all the other caps out there so I’m going to try it first. And it may not work I don’t know for sure. I did have to get them to replace the battery and charger cord but they did so as I would expect them to. Hopefully it will work as described soon.

    • Hey Danny, I think the issue that many seem to have with Kiierr is their actual return policy, which has many many steps to it. If you don’t follow things to a T they appear to not give you your money back. Also, they make the return window very short after the 7 months so make sure you actually pay attention to that. I’m not sure about you but like the individual whose cap didn’t fit you’d be pretty upset if they wouldn’t give you a refund because you didn’t use a product that didn’t fit.

      I know I would, which is why I decided to use a different company.

  5. Scam Scam Scam, this product burned my head and they won’t take it back! Do not purchase this item the company does not stand behind it!!!

    • Hey T.M., I’m really sorry to hear about that. Did Kiierr give a reason about why they wouldn’t take it back as a return? I’m guessing you were still within their refund period, correct?

  6. Yes i too iam experiencing some. Heart ache from returning this product which did not work i followed the refund policy to the letter what happened to me was when i purchased this product a few months later my card was stolen. After the 7 months i reached out to them threw email they do not have a real person to chat with in the refund department i explained the situation to them they emailed me back very unprofessional saying we sent it to your bank they will figure it out ive been to my bank 2 i ‘ve email them multiple times my bank that i have a great relationship with emailed spoke to visa i think my next step is to call the attorney that my brother works for and send out a letter to the Ftc. Iam. Having a meeting with my lawyer cause of all the stress this has cause me

    • Hey Jesus, really sorry to hear about all of these headaches. Did they send you any proof of refund of your Kiierr purchase or anything like that?
