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.

Das sagen Bewerter
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.
I have been using the Kiierr laser cap since 2020. During this time I have more growth on the crown and temples of my head. My hairline has doubled in thickness. I use it every other day for 30 minute... Mehr ansehen
No Customsr Service or Support. I purchased my cap, the most expensive one they sell, during Black Friday sale 2025. I’ve been using it daily since purchasing for 4-1/2 months now. The cap... Mehr ansehen

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.

The device came on time and works as advertised.
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.

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 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.

Antwort von Kiierr Hair Growth
Just arrived
I just started using the product, which arrived faster than expected. I'm hopeful that the product will start producing results within the next few months.

Antwort von Kiierr Hair Growth
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 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.

Antwort von Kiierr Hair Growth
Quick & Clear response
Appreciate the Quick and clear response to all my questions.

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.

I’ve been using this laser hat for the last 5 years religiously to help regrow my hair and I’m super happy with the results. This device stimulates hair follicles to grow and when used in combination with minoxidil it gives fantastic results. I’ll be using a laser hat for the rest of my life! Thanks Kiierr!
