I purchased my Kiierr laser helmet sometime in 2021. I only used it occasionally for the first few years and didn't get much from it which was my own fault. About a year ago my hair was looking terrible so I decided to buckle down and use it consistently for 20 minutes at a time, 5 days per week. After 6 months I noticed a considerable difference both with new hair growth and strengthening my existing hair.

The laser cap works very well. This is my 2nd hat. I have a problem with the battery holding a charge on this order but they are sending me a new one. I am pleased by their customer service.

I started experiencing significant hair loss after Covid in 2021, and then it compounded after a surgery that stressed my body. After researching my options, I purchased a Kiierr cap as well as their DHT blocker supplements, both of which I continue to use. I firmly believe these products have helped me to restore most of my hair over time and has reduced my regular hair loss.

Speedy customer service to bromide a missing headband. Impressive response.

SERVICE: amazing, i recieved my order incomplete email them, answer in 24 hrs and fix it right away! It turn on and everything have used it just a couple of days need more time to try it! I payed the expedite shipping and it came so so fast i couldn’t believe it

Nearly two years ago, I received a Kiierr helmet as a gift, and since then, I've observed noticeable improvements in both the fullness and overall appearance of my hair. Although my results haven't been dramatic, the thinning at my crown has lessened gradually over time, which leads me to believe that my hair loss has mostly stopped. I am genuinely pleased with these ongoing changes. In addition to the product's effectiveness, Kiierr's customer service has consistently exceeded my expectations. Whenever I encountered issues, such as problems with my travel brush or when the battery failed after two years, their team responded quickly and resolved everything efficiently. Their reliable support has made my experience even more positive. And that is worth all the hair in the world! Thank you, Kiierr!

I was a skeptic who thought that using the Kierr helmet and similar ones were scams. Was I wrong!!! After much research, I decided to purchase a Kierr helmet because it seemed to be the best on the market. I've never regretted that decision! The photos attached depict my unbelievable hair growth journey. The first one was taken before using the Kierr helmet and the 2nd and 3rd ones were taken after using it for 8 and 12 months respectively. My hair grew longer and thicker than it was before; to the point that I was even able to braid it (see photo taken after 2 years using the helmet). I became so confident about the results of the Kierr helmet that I felt comfortable cutting my hair (last photo) because I KNEW that, with the Kierr helmet, and normal hair care, it would grow back. When my dermatologist saw the results of using the Kierr helmet, she stated, "That's a head of hair!" She was right!!! Now, I'm no longer self-conscious because of bald patches and feel confident changing my hairstyle; all because of Kierr!! For me, there's no turning back! You'll the same way after you've used the helmet. " The only issue I had was with the battery. . . it stopped working a couple of times. That was no problem; however, as Kierr's customer service is responsive, helpful and courteous. They replaced the battery free of cost both times! That's one more reason to purchase a Kierr helmet.

For many years, I accepted the progression of male pattern baldness based on genetics was an inevitable part of life for most guys. In 2022, I decided to give a Kiierr laser cap a try. At the time, my bald spot was quite apparent and growing. I did not expect the cap to regrow all the lost hair in the bald spot. Based on what I had read about hair restoration, I waited too long and hence did not think that was realistic. Using the cap as directed, I now have some fuzzy downy strands of hair in the most problematic area (image 1). However, and more importantly, the cap has significantly slowed the progression of male pattern baldness. I have maintained a reasonable hairline when viewed from the front, which as my hope (image 2).

We ordered the hat for my father who's hair was thinning. He was reluctant to try it (at first) but then started using it as instructed and was consistent. Lo and Behold at the age of 78 years old his hair was growing back! The hat works and it is really easy to use as he would sit and watch tv with it on. We highly recommend this product.

Attached is my before and after, this is Jan. of 2020 on the right and Nov. of 2025 on the left. I am obviously very happy that I purchase the Kiierr cap and the results you see speak for themselves. I would hate to see where my hair loss would be without the Kiierr cap. It is wellworth the money and a simple, easy and effective way to help with hair loss.

I am definitely a satisfied and longtime Kiierr customer since March of 2022. My Kiierr cap has been easy to use and very comfortable. It definitely helps me minimize any hair thinning and loss, and aids regrowth. I have found it to be a important tool in my hair regrowth journey. I recommend it.

I have been using Kiier laser cap since March 2022. I am happy with the product and the service from the company. After about four years of continuous use, the battery started having a small issue. The problem was resolved to my satisfaction as soon as I contacted Kiierr. I would say the product and the company both are very reliable. They have my full confidence.

My wife entered menopause a few years ago and she started to have hair loss. She saw a dermatologist in our area that ordered lab work for wife. After results came in, nothing unusual came up. So, the dermatologist mentioned that my wife could try Kiierr laser cap as an additional help for hair loss. So, we bought the cap in 2021 and my wife (and I…) have been using it every other day. We’d say that this device has been helping us with our hair. My wife feels that she has much fuller hair than before and, in my case, I feel that the use of the laser cap has slowed down my thinning hair process. Thanks. Paulo Borges

I use the cap as directed and it's easy to use.

The results I achieved with regular use of the cap were quite remarkable. The regrowth is not quick but it is consistent. It took about 3 months of regular use to start to see results but it was worth the effort. I would highly recommend this method. It works! And stop putting useless and expensive products in your hair. They don't work.

I have been using Kiierr Laser from November 2020. I have used the cap, the shampoo and conditioner and the supplements all this time. When I started I was combing out hair and my comb had hair on it. After I used the Kiierr products, the hair stopped coming out and it felt stronger. My barber noticed a significant difference and mentioned it me. I have been so thankful to find this produce and the help it has provided.

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!!)

Dear Kiierr, I just want to thank you for your product. I have been using the laser cap 302 for over 6 months now and I have seen drastic differences. I travel quite a bit for work and I always make it a priority that I bring my Kiierr on planes and train. The 6 minutes a day is quite convenient and goes by very quickly as I am normally on my phone or reading a book. Thanks!

I have been using a Kiierr laser cap and hair supplements for five years now and I have seen such a difference I will never go back!
