Great customer support. I received answers to my (shipping) questions almost instantly. Kiierr was able to change delivery times to ensure that I was home to receive my nifty laser cap.

Customer service continues to be amazing. I lost my charger and customer service agent went through everything step by step even when this boomer could have driven anyone in tech crazy.

Trustpilot encourages honest customer…

*Updating this review* I strongly regret purchasing from this company and wish I'd read the critical reviews more carefully first.

I received a Kiierr cap that doesn't fit despite my head being well within their advertised sizing. The product is much smaller than specified and sits awkwardly high. After immediately contacting customer service with requests for a refund and support, I have received no response to any of my attempts at resolution.

The cap I received is unbranded and looks nothing like the marketing photos. It appears identical to generic Chinese white-labeled products available on xxxx for a fraction of the price. When I raised this with the company, their response was that "customers prefer" unbranded caps - a claim I find impossible to believe given the premium price point.

Examining the review patterns raises serious concerns: most five-star ratings come from accounts with only one review, posted shortly after purchase. There's minimal evidence of long-term use or actual results, and hardly any genuine user photos. Just generic praise about shipping and ordering that tells you nothing about whether the medical device actually works. Meanwhile, negative reviews about fit, sizing, and returns receive no meaningful reply or resolution.

Kiierr charges premium prices for a product they refuse to support or service properly.

Based on my direct experience, I cannot recommend this company due to their non-responsive customer service and what appears to be a rebranded generic product sold at a significant markup.

Also notice the brand new review from a customer who has owned the product for 1 month, who claims it fits his large head.

I don't think that that review is a coincidence. Do what you will with that information.

Quick to answer or help..............

When you write and ask a question or have a concern this company is quick to write you back. I had a few questions and each time within the SAME day I got an answer. I am sure sometimes they may have to investigate your question, but on all my questions, I got fast responses. Tell me, how many companies do you know that has that reputation.

The item arrived in pristine condition but as it arrived from USA, I had to go out and get a USA to UK adapter.
I charged up the battery and used it for the first time, for 6mins, all good and very high quality product.

I could not give it 5 stars yet

I could not give it 5 stars yet. So far so good though. I just received the 272 Dual Wave Laser hat several weeks ago so I have not seen its hair growing affects to date, but I do know that my right knee felt a little pain i.e., tweaky so I used it over my knee and it has seemed to have recovered. No more pain, so it indicates to me that the laser is working. More details to come on the hair growth side in the future.

Experience so far

I have a pretty big head and it fits me well. Ive only been using it for about a month so I have a while before I know if it actually works. I'll update the review after a few months. I actually find it relaxing to wear and nod of sometimes.

Hat size is misleading

I wrote customer service regarding the size of the hat which sits rather high on the crown of my head. The ad says the 272 premier hat is 23 or 23.5 inches in circumference. In reality they measured the outside perimeter of the hat. The actual inside perimeter seems to be closer to 22 inches. Mt head measures 23.5 inches and it concerns me that the hat sits high on my head and although I asked customer service about this, 5 days later I have received no response.

Hi Gary.

Thank you for sharing your feedback. We truly do respond to every single email, so if you haven’t seen a reply yet, it may have landed in your spam or junk folder. Please check there just in case.

The Kiierr 272 Premier cap has an outer perimeter of about 23.5 inches, but since everyone’s head shape is a little different, it can sometimes sit slightly higher on certain heads while still fitting correctly for treatment. That said, we want you to feel completely comfortable with your cap and results.

If you’re experiencing any issues with the fit, please reach out to our refund department at refunds@kiierr.com. We’ll be happy to review your situation and do whatever we can to resolve it and make sure you’re fully satisfied.

Things Are Looking Up, I Hope

At what has been a stressful time for me, a female, with sudden hair loss, I found Kiierr's website to be very informative, helpful and hopeful for my situation. Ordering was easy, delivery came promptly, and the instructions were easy to follow. I also appreciate their Growth Guarantee policy and the fact that they helped me to easily obtain a Medical Necessity letter so I could pay for their product using my health savings account.

Delivery and customer service are…

Delivery and customer service are great! The cap is sturdy, using the 302 MD Ultra Flex, and after four months of usage I might be seeing results. It’s hard to tell thus far. I have used it daily and not missed a day, and will continue doing so, because from experience bodily change might take time, even if it’s hard to discern clear results at this moment in time.

I had a great experience with kiierr

I had a great experience with kiierr. I had great results with the laser cap, and I liked that it came with the red and blue laser brush. I also liked the shampoo that was given to me as well. The carrying case made it very easy to be able to use it consistently, even though I was traveling. The only downside is how many times that my order was delayed because of how many orders there were.

Super comfortable and hassle free

The laser cap is super comfortable and easy to operate. It automatically turns off after 6 minutes, making the whole experience hassle free. It will warm your scalp a little, which I found very pleasant. Highly recommend this product if you are in the market for laser treatment.

No email receipt received with order…

No email receipt received when I ordered. No tracking number provided for purchase. Package upon arrival required a signature, but I was not aware of that or available when item arrived. A note was left on door for final attempt delivery; I had to contact deliver and arrange to pick up at alternative locations.

Hi James,

Thank you for reaching out and I’m sorry for the confusion. An order confirmation and tracking email were both sent automatically after your purchase, but it’s possible they may have landed in your spam or junk folder.

We do require a signature for delivery to ensure your device arrives safely, though I understand that can be inconvenient if you weren’t aware. I’m glad to hear you were able to arrange pickup and receive your package.

I could not be happier with my results

I could not be happier with my results. They're truly unbelievable, and I never thought they could have been achieved in my case. I have never had a fuller head of hair than I have now. I started using their shampoo and conditioner, which now are my favorite products. Thank you so much, Kiierr family, for your excellent product and customer service (Jami is the best!!)

i was concered with possible hair loss since my father was half bald in his mid 20's. 4 years ago I noticed some thinning in the back of my head. I purchsed your product and used it per instructions for a few years. My barber and say a thickening of my entire head and the small thin spot was filled in. I have a full head of hair ever since and am a believer in the product.
