I’ve been using my Kiierr cap consistently for about 3 years. In the beginning, I used it every other day, and after about 9 months, I switched to twice a week. I definitely saw noticeable results within those first 9 months! Over time, I got so used to it that I started wondering if it was still making a difference. Then, about two months ago, my battery stopped working, so I stopped using the cap. A month later, I noticed I was shedding much more hair in the shower than usual, and when I looked closely, I could see my hair thinning again. That’s when I realized—this product really does work! I contacted customer service, and they were wonderful. They helped me troubleshoot the problem and replace my battery quickly—I felt very supported. Now I can’t wait to start using my Kiierr cap again! I’ve included photos to show the difference: the first is before I started using the cap, and the second shows how much regrowth I had along my hairline. And keep in mind—that second photo was taken after I stopped using the cap for 2 months!

I have been using my Kiierr laser cap for the several years sporadically however this year committed to the recommended 30 mins/3 days a week. It is easy to adhere to as the unit automatically turns off after 30 minutes. The results are tremendous: new thick growth and a noticeable decrease in shedding. I even take it on vacation with me, it is so easy to use and travel with. Highly recommend for anyone with thinning hair!

I bought the Kiierr laser cap a few years ago in a state of utter panic, after noticing the sparse growth on my crown area. At the same time, I also ordered a whole bunch of serums, from various reputed companies, After going through bottles of product, month after month, year after year, with barely visible results, I started using my Kiierr laser cap regularly. Within a few weeks, I noticed baby hairs at my hairline and the same baby hairs are now shoulder length! When I stop using the cap, I clearly notice a difference - the cap invigorates the roots and truly provides a volumizing effect on existing hair. Trust the Kiierr caps to work their magic and remember consistency is key! Thank you Kiierr :hands_heart:

These pictures are taken about 2 1/2 years apart. I’ve been very happy with the results that I’ve gotten from my laser hair cap from Kiier in addition to the supplements that I’ve purchased. I’m 50 years old at this point and feel that these therapies would’ve helped me even more if I had started earlier in my hair loss process. My hair loss really began in my late 20’s.

I boght the Laser cap in April 2025 and August of 17 stop working not happy , I call the office NO REPONSE very DISSATISFIED

This is a great company and their have great products! Their customer service is exceptional!

Kiierr is a world class hair regrowth business that sells superior products. I have been using a Kiierr laser cap for over 5 years and couldn't be happier with the results. After 7 months of use I noticed a moderate amount of very fine hair growing on my scalp. Over time the fine hairs became stronger and longer. After several years of use I am happy with how my hair looks. I will continue to use the laser cap as it feels good on my head and I can do my normal activities while wearing the laser cap. Thanks Kiierr for providing a great hair product and for your caring customer service department.

I have been using the Kierr laser cap for 4 years. Before I started using it I had a really annoying itchy feeling at the crown of my head. Since using Kierr that itchiness has stopped. In fact when I stopped using it a couple weeks it has returned so I am confident it is from the laser cap. I am sure it has also helped maintain or improve the hair growth on my head as well, though I have done other things in addition to Kierr for that. Great product.

My Kiierr laser cap saved me from losing my hair I was diagnosed with lichen planopilaris in early 2021. I was told that women often were bald in a year with this diagnosis. You can see I had significant hair loss above my ears. My hairline was also receding. I was told that the kiierr cap might help I ordered one immediately and started using it to help with the inflammation. The hair loss stopped and my hair looks beautiful Thank you Kiierr!!

I've been using the 272 Premier Kiierr cap since February of this year and am seeing good results already, less shedding overall. When I stopped using it for a few weeks when on vacation, I was losing more hair in the shower. I started it again and the excessive shedding stopped. I'm looking forward to seeing future results.

I began losing hair after menopause. I was looking for a way to make my hair healthier when I read about the laser cap. I was hesitant about such an expensive purchase, but as you can see from the before and after photos, it made a difference! (The photos are 4 months apart. ) I have been using my cap for 3 1/2 years now.

On April 11th 2023 I got a brain operation done, where they removed a benign ( good) tumor of 6. 5 cm x 5 cm out of my little head. It started with vision loss in my right eye. I could only see about 5-10%. After an MRI of the head, they discovered this “little friend” living in my head, which was pressing on my R optical nerve, and because of that, I was losing vision! No panic!! I had an amazing team of doctors and nurses who took care of me. What was supposed to be a 6 hour operation, turned into an 8h 20 min operation from the time of incision. The neurosurgeon told me that I might have a few issues after the operation, of which my hair not being able to grow back where they cut me open in the hairline, from L ear to R ear. Long story short…. . God had other plans…. Where I was supposed to stay 5-7 days in the hospital, and of that 1 day ICU, turned out that I stayed 2 days in ICU and I was strong enough to go back home!! I wasn’t allowed to wash my hair in the beginning. Later on with only Johnson and Johnson baby shampoo and conditioner. No coloring of the hair… Weeks went by and I recovered pretty quickly. But all of a sudden, I noticed a lot of loss of hair. Losing hair in huge bundles…. ! I got scared and in a panic mode…. Even worse, when my friend asked me if I was losing hair…. I asked how she knew, and she said that there was a huge “hole” in the back of my head with no hair. So I started to investigate what I could do to help myself!! One of my neighbors was sharing with me, that she was selling these LED light brushes in her salon and with great results. Knowing myself…. I started to investigate many different products and why one product to say yes to and run from the next one. So I ended up on Kiierr. com, after my research. I was happy to find out that Kiierr had Medical grade Laser in the helmet, and that was what I was looking for!! I bought one and started to use it every day. Honestly…. I would wear it a few time longer, after t...

WE ALL KNOW THAT THESE LASER CAPS ARE WONDERFUL DEVICES THAT CAN HELP A LOT OF PEOPLE GROW BACK SOME HAIR THAT HAS BEEN LOST FOR VARIOUS REASONS. WE ALSO KNOW THAT SOME PEOPLE ARE BEYOND HELP AND NOTHING WILL WORK FOR THEM. I THOUGHT I MIGHT BE IN THE LATTER GROUP. I HAVE BEEN USING THE LASER CAP FOR A LITTLE OVER 3 YEARS. MY SITUATION IS PERHAPS A LITTLE DIFFERENT FROM OTHERS. I DID NOT SEE MUCH HAIR GROWTH. RECENTLY THE CAP WAS DAMAGED AND I STOPPED USING IT AND THAT'S WHEN I REALLY DISCOVERED ITS BENEFIT. THE HAIR STARTED FALLING OUT WITH MORE FREQUENCY AND I CAME TO REALIZE THE CAP WAS THE ONE THING THAT WAS PREVENTING FURTHER HAIR LOSS. WITH THE CAP BACK IN SERVICE I CAN HAPPILY MAINTAIN THE HAIR I STILL HAVE AND CALL IT A WIN.

I have been very impressed with the results of the Kiierr red-light therapy cap. While I do not have "before and after photos" of my results, I have noticed my hair growth has improved with less thinning around my hairline and crown of my scalp. The customer service provided by the company has been outstanding, and I will recommend this product to anyone needing help with thinning hair.

This has been a great addition to my beauty routine. As a woman in my late forties, I purchased the cap when I noticed patches of thinning hair which made me feel very self-conscious. I tried other topical products, but they didn't do much. I have been using the Kierr cap for around 4-5 years now, I have noticed I have more even hair growth in the areas that concerned me (temples and top of head). I feel much more confident. Customer service has been great also for anything I needed to reach out for.

I am absolutely amazed at the results from my Kiierr cap. Not only have I grown fuller hair but it is healthier and thicker. I used to have baby fine hair and now it is naturally thicker and fuller. I will continue to use it because it is so healthy for not just my hair but my scalp.

I've been very impressed with the laser cap I purchased a few years ago. I've also been impressed with the support I've received from the company. Everyone has been very attentive to my needs.

Kiierr Hair Laser Cap definitely improved my hair density and strength over constant use during last 3 years. The cap is very safe and easy to use. It requires only 30 minutes of use every other day and it is simple as wearing a hat – no messy topicals or complicated routines. The treatment is completely painless and has zero side effects. I definitely see my hair improvement and less hair loss over last 3 years, Very active supporter of Kiierr Hair Laser Cap and company's superior customer service.

Well packaged, shipped relatively quickly, when I had questions the team responded quickly and were flexible.

I ordered my 272 Premier Laser Cap directly through the Kiierr website and it arrived very quickly, excellently packaged, brand new, and in perfect shape! I only received my Cap a couple of weeks ago, so it's a little too soon to expect results yet, but so far customer service has been great! They have responded very quickly to my email inquiries! I also ordered some shampoo, conditioner, and vitamins from the Kiierr site to try those as well. I will post an updated review with photos when I start getting results.
