I recently purchased my laser cap from Kiierr, and while it's still too early to comment on the results, I've been genuinely impressed by their customer service. They've been courteous, attentive and clearly focused on making sure their customers feel supported and satisfied with their purchase. It's reassuring to see a company that truly cares about customer satisfaction. Overall a very positive experience.

Awesome product that I saw great results within a few months. I've been using it for 5 years now and have kept great volume.

I first tried topical solutions for my thinning scalp, but I hated the smell and the mess. So I looked for other alternatives. I then discovered laser therapy. I saw tests done on their effectiveness so I purchased a handheld laser comb. I tried it for a while but it was time consuming and hard to be diligent to keep combing for the entire suggested time. So I decided to look into laser caps. My research took me to Kiierr and it seemed like one of the best on the market for the price. I purchased the Kiierr 272 Premier Laser Cap. The fact that it was cleared through FDA was important to me. I know that laser therapy for hair loss doesn’t work for everyone, but I have confidence in the effectiveness of Kiierr. If laser therapy will work for me I felt certain that Kiierr was my answer.

I’ve had thinning hair in the front of my scalp for some years and I was worried about it all falling out at some point. So I’ve been using the Care laser, red light therapy cap and not only is the hair stain, but it’s actually thickening. We all get old and nobody wants to look old so I’m happy that I have my hair. Thank you very much.

I absolutely love Kiierr! Their products are top-notch and deliver real results, and their customer service is outstanding—responsive, friendly, and genuinely helpful. From start to finish, they make the entire experience seamless and stress-free. It’s rare to find a company that combines quality products with such exceptional support, and Kiierr truly stands out. Highly recommend them to anyone looking for reliability and care!

I have been using a Kiierr cap for 5 years and have seen amazing results! I wear the hat every other day and the density of my hair has increased. I’m extremely satisfied with the results and would recommend these caps to anyone experiencing hair loss and thinning.

Before trying Kiierr i was very skeptical and apprehensive. After using for a couple years, i have experienced some hair growth but more importantly for myself, I have not lost anymore hair. I would highly recommend this product m

I've been a customer of Kiierr for almost five years and have absolutely loved the product, seen strong hair growth on the front region of my scalp. Their customer service was very responsive while troubleshooting a simple fix on the device. Great company.

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.
