Customer service is excellent! I asked to buy a new charger, they decided to help me get it working before I spend money. Their service reminded me of A Miracle on 34th st when Santa sends customers to A & S

People with hair loss should try this cap because it work for the people with hair loss ,I think that the cap does wonder for us all

Had an issue with the battery. Problem was diagnosed quickly and a new battery was sent right away!

After using the red light cap for a couple of years and loving that, I also used the DHT blocking shampoo and conditioner and have recently tried their new hair dye shampoo. It’s been great so far! I find it much better than constantly dying my roots and it’s a more natural and subtle look that the skunk line I used to have. Kiierr has great customer service and I’m super happy with all the products I’ve tried! The photo is 5 weeks of grow out which usually is a silver line down my part.

Great service.

We have had the Kiierr system for a little over 2 years and it is definitely helping. We follow the 30 minute every other day schedule. We had a minor problem with the equipment that was handled quickly and professionally by their service department. Kiierr is a good company to do business with

The Power Bank for my Kiierr Laser Cap failed after 2 months. I contacted the Company by e-mail and was immediately provided troubleshooting instructions. With no success the Company is shipping me a new Power Bank. . . . . . All this accomplished in same day. Thank you Steven (Service Manager). . . . . . . . Great product and equally great customer service.

I bought a few products from Kiierr. I love them all and have had amazing experiences with this company! This cap works! My hair grew so fast and came in thicker. This is a quality cap and the best on the market, backed by science. I highly recommend! I am feeling 10-15 younger, getting my confidence back! Thank you Kiierr!

I needed to return my item, and the return process was the best customer service experience I've ever had. Great Company!!

I purchased the Kiierr Laser Cap several years ago using it 3 x a week as recommended and it worked perfectly. Unfortunately, it recently stopped working LONG after the original warranty had expired. While I was disappointed that a product at this price didn't last longer, I decided to reach out to customer service to see what their recommendation might be. I am extremely impressed with the team at Kiierr. Despite being out of warranty, their support team was prompt, professional, and genuinely wanted to help. They didn’t just send me a generic "it's broken" response. Instead, they walked me through troubleshooting steps. When that didn't work, they offered a replacement Kiierr laser cap at a favorable cost. Great performance from the original Kiierr laser cap while it lasted. Phenomenal customer support team. Overall: While I wish the product had lasted longer, the company really stood behind their brand. Knowing they treat customers well even after the warranty expires means I will likely buy from them again. Good customer service makes all the difference!.

I was a little skeptical about whether the Kiieer cap I purchased would actually work. My hair was starting to thin a little and I was concerned about what the future might bring. I used it every other day like they recommended. I took photos every month for the first 6 months to do a comparison. I noticed a difference. It’s not like suddenly a bushy head of hair, but it works. Been using it continually for over two 2 years now and my hair is holding steady. My wife noticed a difference and she started using it about a year ago. I would buy it gain.

I have had this product for 1 year. It does make my existing hair grow faster but the jury is out if I am getting NEW follicles. But I still like it for the FAST growth. I know because I color my hair and now I have to color it more frequently (4 weeks instead of 6) because the gray roots show up much sooner! That said, this review is for Kiierr standing behind their warranty. I received help from Steven, Tech Manager. My battery would not charge past 1 bar, which means you are not getting the full strength of the lasers, per the manual (they recommend keeping it charged between 2 - 4 bars). I thought I would have to wait for a new battery to be shipped. Steven responded quickly, and gave me a couple of solutions to try. The first one worked perfectly. And I didn't have to wait long for a response (2 days) so I didn't lose ground on my treatments! Very happy. Tip, just make sure to save your ORDER NUMBER as they confirm your warranty off of that. My warranty is for 2 years from date I received the cap.

This design is superb for numerous reasons. Firstly it is completely portable. Plug in the battery and place it in your pocket and carry on with whatever it is you are doing. The bleep reminds you when you are halfway through the session and the final bleep let's you know when you are done. I love walking around the house with my laser cap under the Kiierr baseball cap. Everyone is intrigued when I enter the living room wearing it. No one has a clue what's going on and I just have this dead pan look on my face like nothing unusual is going on . . . . until someone blurts out. . . . . why is your baseball cap flashing red? I tell the children that I am speaking to someone from another planet and I tell the adults that it is a special infra red ray that helps me to think. . . . . . that I use it for problem solving. They all smile, but with a kind of curiousity. . . . they want to know more. Eventually I tell them what it is really for, but I certainly have fun with it before I do.

Customer service is great! Just started using hat so not sure yet about my hair

Support service is very good and fast to respond.

My hair loss began ten years ago. There wasn’t anything I didn’t do to fix it, I thought. Minoxidil, hormones, DHT blockers etc. I lived with constant worry and even nightmares about super thin hair and scalp showing. Changing hairstyles to hide the thin areas and baseball caps. Four years ago I noticed that much of my hair although still coming in had a short growth cycle and very fine hairs. After hearing a podcast about the science of red light I decided to research which company to choose and of course found Kiierr as the number one. I purchased the strongest cap and began consistently using it. Well my results are insane! I’m so happy. The after pictures are only after five month. Kiierr is an exceptional company that provided support to me in many ways. Really amazing. Thank you Kiierr

I can happily say I’ve been a repeat customer of Kiierr products including the laser cap and I have had wonderful results. I would definitely recommend this company to anyone desiring an improvement in their hair and scalp. Also, Kiierr customer service is top-notch with an exemplary response time. Lastly, their website is easy to use and has a variety of your favorite products to select from for safe shipment. Kiierr staff works seamlessly allowing you to reach out to customer service at any time. I can confirm that you will receive an almost immediate response and support from Kiierr. This company not only has great products, but they also really do go above and beyond to support their customers.

new to the program. Bought the cap. Unfortunately had a bad battery pack. But, within the day, I was notified that a replacement was on its way. Excellent service and standing behind the product. Much appreciated.

I am extremely happy with the results I have achieved with my Kiierr International laser cap. I purchased my hat in 2018 and have been using it regularly since then. I have seen so much improvement, and if I had not been using it I feel that I would have lost most of the hair on the top of my head. I would highly recommend a Kiierr International cap to anyone looking to restore their hair growth.

The customer service is the best I have ever experienced with any company. I retired from a dermatologist office and I have bought and sold many products. I have used your vitamins, shampoo and conditioner for years. I have one of your first laser caps, the wand and mask. My mom will be 96 in a few weeks and give her the vitamins too. My daughter also uses your serum, wand and ipl. WW The packaging is solid, I have never had an issue with damaged products. The best part about this company is their customer service. They truly stand by their products. I have reached out to them on a few occasions helping me with the use of a product. They are very courteous and quick to respond which in resolving my issues everytime. I trust this company.
