Despite very serious delivery issues with FedEx France, Kiierr’s customer service was absolutely outstanding. Responsive, professional, transparent, and fully committed to resolving the situation until the end. A rare and genuinely excellent level of customer support that deserves recognition.

Using the 272 cap consistently has significantly helped me control my scalp Psoriasis.

I have used the Kiierr Laser Caps since 2020. I use the laser cap for 30 minutes per day, every other day. The red light therapy on the scalp helps hair growth, and neutralizes hair loss. My hair is thicker and fuller since using the Kiierr Laser Cap. Very satisfied with the product and encourage any men who struggle with hair loss to try the product

I successfully use the Kiierr Cap to stop hair loss

I tried all sorts of medications for hair growth that did not work for the bald spot on the crown of my head. I read all the positive customer reviews of the Kiierr laser caps and decided to give one a try. It was very easy and convenient to use. Within 3 months, I started to grow hair! After one year, my bald spot was noticeably covered! I am very pleased with the results!

I have been using the 272 cap for almost 7 years now and it is clear to me how much it has helped put hair back on my head. During this time I have also used the Kiierr shampoo and conditioner as well as used Rogaine foam. I must add that I used just Rogaine foam for years before adding the cap and I believe I just loss hair at a slower rate of speed. Adding the cap and hair care products from Kiierr made the growth difference for me. Thanks Kiierr!

I’ve been using my Kiierr red light hair growth cap for about three years now, and I’m very pleased with my results. I originally started using the cap due to noticeable shedding, which was concerning and prompted me to look for effective hair growth solutions. After consistent use, the excessive shedding stopped, and my hair feels healthier and stronger overall. The Kiierr cap has become an important part of my hair growth arsenal, and I truly believe it has contributed to maintaining my hair and improving its condition over time. I appreciate how easy it is to use and how seamlessly it fits into my routine

Great product!!

Great product! You can definitely tell the difference in both texture and thickness of your hair. It would be 5 Stars if they made the Cap a bit larger. The 272 Premier is fantastic except for being a tad small on the head.

I’ve been using the Kiierr 272 Premier Laser Cap, and I’m genuinely impressed with the results. After an extended illness, I had extreme hair loss. My hair stylist recommended I look into laser hats for regrowth. I found the Kiier 272. I was skeptical at first, but after consistent use, I can confidently say that my hair grew back very nicely. I noticed reduced shedding first, followed by visible regrowth and thicker-looking hair in areas that had been thinning. The cap is easy to use and comfortable to wear, and I appreciate that it fits into my routine without being time-consuming. I also like that it’s a drug-free option for hair regrowth, which was important to me. What really stands out is that the results look natural—my hair feels healthier, fuller, and stronger than before. Friends and family even commented on the improvement before I mentioned I was using anything. If you’re willing to be consistent and patient, the Kiierr 272 Premier truly delivers. I’m very happy with my experience and would absolutely recommend it to anyone dealing with hair thinning or hair loss. Kiiers customer service is prompt and professional as well. I’m a very happy customer😁

I received a device that did not work. Once I reached out, I was given help by Steven to rectify the situation; once all efforts were exhausted I was instructed to return the device for either repair or replacement. Within days, I received my new device and it works perfectly. My experience with customer service was excellent- particularly since most of our communications were during the holidays. Many thanks!

I am a very satisfied customer using the laser cap (on a consistent basis) for more than 3 years. I highly recommend the product to anyone looking to improve thinning hair and their hair's overall health, The customer service is also of the highest standard. During my interaction with Steven, Kiierr's customer service personnel, I felt like a valued and supported customer. He answered my question quickly and resolved the issue very much to my satisfaction. I am highly satisfied with the product and the customer service I received. I will be a Kiierr customer using my laser cap for many years to come!

I had a severe case of covid 19. 4 months after recovering my hair began to fall out in large clumps and my crown was completely bald. I read that red light therapy would help and the Kiierr CAP was rated highest among the many products available. I purchased it and used it per instructions and my hair began to grow back. Within a few months it returned to my preCovid level. I had another bout of COVID and will be repeating this process. I am grateful to have solutions like this marvelous cap to reduce the stress and concerns that come along with unexpected illness and know there are remedies that support my return to normalcy.

I have been using the Kierr Laser 272 cap for several years and have been delighted with the results. The "before" picture shows how I was continuing to lose hair from the top of my head, with larger and larger patches of skin showing. The "after" picture taken just a few days ago shows that I now have an even growth of hair on that area of my head. I use the Kierr Laser cap for 30 minutes each day in the morning. Nothing could be easier for such nice results!

When I started using my Kiierr laser cap 3 years ago, I wasn't sure what to expect but now - I can honestly say it was one of the best decisions I've made for myself. It took several weeks to start to see results and with regular use of the cap my hair is now fuller, stronger and healthier. I am extremely pleased with the results. The cap is lightweight, comfortable and super easy to use. I just pop it on while watching TV or reading and it does all the work. There's no pain, no mess and no complicated setup. If you’re struggling with thinning hair or just want to boost your hair’s health, I can’t recommend this enough. It’s an investment, but for me, it’s been worth every penny. I will continue to use the cap regularly for many years to come!

I have been a dedicated customer since 2018. I was in my early 50s and started having menopausal hair loss. I saw the science that backed the claims and decided to give it a try. Over these last seven years I have consistently used the cap. I’m so pleased with how rich and full my hair is. Also, when I have had any issues whatsoever, which have been limited, the customer service is immediately responsive. This is an incredible company with a great product that delivers.
