Hello and good afternoon. Just had the privilege of chatting with representative Steven , who was very courteous and informative. Recently my Mother purchased a laser cap for me on Christmas. As she realized how much my hair loss was affecting my self esteem . And that I had become quite frustrated with all my failed attempts at various shampoo's , vitamin supplements, ect . I'm proud to say this has been an amazing experience with most excellent results. I've really noticed a considerable difference. And that my existing hair even feels stronger ! Sadly ,my Mother has since passed on. She was a most incredible and thoughtful soul. . Not just to her children but to all she met . And I'm proud to say I still use the Kiierr laser cap 4 days a week . It's truly the gift that keeps on giving !

I have the miracle wand and the full silicone mask — both have various settings and colors for specific cell rejuvenating and healing. I was skeptical at first but using the wand at least once a week especially on blemishes and sun spots showed to be real— the mask is all in one and highly recommend the product.

I’ve been using my Kiierr red light therapy hat consistently for about six years now, and I can honestly say it’s one of the best investments I’ve made for my hair. When I first started, I was dealing with noticeable thinning, especially around the crown and temples. I wasn’t expecting miracles, but over the first several months I began to see less shedding and subtle regrowth. Fast forward to now, my hair is noticeably thicker, healthier, and much more stable than it was before I started. What I really appreciate is how easy it is to use. The sessions are short, completely painless, and fit easily into a busy schedule. It’s become part of my routine without feeling like a chore. The build quality has also held up really well over the years, which speaks to the durability of the device. Consistency is definitely key with this kind of treatment, but if you stick with it, the results can be very real. For me, it’s been a reliable, non-invasive option that actually delivered long-term improvement. Overall, I highly recommend the Kiierr hat to anyone dealing with hair thinning who is looking for a low-maintenance, drug-free solution that works over time.

I have used the 272 for several years and was happy with the it. I wanted to upgrade to the newer product so I ordered the 312. I had some problems with it and Kiierr helped me to troubleshoot the entire process. It turned out the cap was defective. I returned it and received a replacement immediately. Throughout this process Kierr was timely and very responsive to my situation. I am now looking forward to using my 312 and seeing improved results in a few weeks.

I highly recommend the Kiierr Laser Cap. I first started using it in 2020 when I noticed a receding hair line and some increased overall hair loss. It does require patience and consistency, after a few months I began to see a reduction in hair loss, followed by regrowth in the front. Over time, the results continued to improve, I am a strong believer in this product, I have been using it now for over 5 years and plan to continue it long term.

The red light cap and vitamins really do work! I give it a 10/10. My bf been using it 2 months and we see a significant difference. Thank you Kiierr.

I had a great experience with Kiierr International’s customer support team. When the power bank for my device stopped working, they responded quickly and immediately sent me a replacement without any hassle. Their communication was prompt, helpful, and very professional, which made the whole process smooth and stress-free. As for the product itself, I’ve been using the laser cap consistently and so far I’m seeing positive results. It seems to be working well, and I’m looking forward to even better improvements over time. Overall, I’m very satisfied with both the product and the excellent customer service. Highly recommend!

My dr told me to buy an LLLT cap so I told her I had one sitting in the closet, which I'd forgotten about. lol. I pulled it out and started using it again to promote new hair growth. You can see in my pics from Sept, 2025 to now, April, 2026 that the hair is growing . When I blow my hair dry, I see alllll of the various lengths of new hair all over my head. I can hardly wait for it all to grow out long enough to cut to the same length. I wear my hair long and right now my ends are very thin, but once all of that new hair grows out, my ends will be thick. Many thanks to the Kiier LLLT Laser Cap for helping me along my journey.

Using this device consistently has made a real difference for me. Over time, I’ve noticed my hair becoming stronger, fuller, and healthier, with significantly less shedding than before. The changes didn’t happen overnight, but with fidelity to the process, the results have been steady and noticeable.

I just received my cap, so I can not say how effective it will be, however I am very hopeful. My experience with Kiierr so far has been excellent. My questions have been answered very promptly and kindly. I received a sale price that came out the day after my order was completed and it was given me without hesitation and enthusiastically. I have really felt like they want to help me with this process. Thank you so much!

Both my wife and I started using the laser cap in November. She was concerning with thinning at the front of her scalp and I needed overall increase hair growth on my scalp. We have both had significant increased growth to where I would say my hair has more than doubled and my wife's concerns are greatly improved as well.

The Kiierr helmet is so comfortable and easy to use. My puppy even fell in love with it AND chewed my charge cord. Of course, it is too early to see the results, but my scalp already feels as though the therapy is working. I am not young, so it may take a bit longer for it to show obvious improvement. Please send me a new cord, ASAP, because I am on the every other day therapy.

I started using the cap a few years ago and I still have hair on my head.

I give them 5 Stars before even starting treatment! I'll reserve the final evaluation for several months when I'm on my way to regrowth. I haven't received my cap to date and am excited to begin. I had a distressing concern after I had placed an order for a supplement. To my overwhelming satisfaction, they returned my email the same day and resolved my concern the same day (unbelievable). I know many other companies that would not have accomplished what they did with my issue. Please be advised that you could do no better elsewhere with such stellar service if you would ever need. it.

I'm just starting my treatment journey, but I wanted to review the pre-purchase and unboxing experience here because it's been genuinely impressive. The website is one of the better ones I've encountered for a considered purchase like this. The comparison between models is clear, the science is explained without being dumbed down, and I left feeling like I actually understood what I was buying and why the 302 MD Ultra was the right call for my goals. No guesswork, no vague marketing fluff. Email support was equally strong. Responsive, knowledgeable, and they treated me like someone capable of handling real information rather than a liability to be managed with boilerplate. That matters when you're spending serious money on something like this. The unboxing experience was legitimately thoughtful. Well-organized, professional presentation, everything clearly labeled and logically sequenced. It felt like a premium product before I even powered it on. If the product delivers like the customer experience has, and I believe it will, I'll absolutely continue to be a fan.

I am very happy with the results using the Kiierr laser cap. I'm enclosing results after about 10 months of use.

I've had a really good experience with Kiierr so far. The cap itself is easy to use, and their customer service has been especially helpful and responsive when I had an issue. They made the process smooth and stress free, which I really appreciate. Looking forward to continuing the treatment!

Kiierr has the best red light laser caps! Their caps are very affordable compared to other brands, all while providing excellent quality, comfort, and effectiveness. I've had great results with my laser cap, and Kiierr truly has the greatest customer service. I recommend the Kiierr Laser Cap to anyone experiencing hair thinning!

Had a problem with shipping. Steve the product manager took control of the situation and upgrade my order and I received it in 2 days "wow". I have dealt with many companies in the past but Kiierr went above and beyond to get this cap to me. Highly recommend this product. After 6 minutes of use you can still feel your scalp tingling with joy. Can't wait to see results. Thanks again Steve you are the best!

I have been using a number of Kiierr products for several of years including a cap to promote hair growth. I have been very pleased with the results to date and have been especially pleased with Kiierr’s prompt to any and all questions I have regarding product use.
