I can happily say I’ve been a repeat customer of Kiierr products including the laser cap and I have had wonderful results. I would definitely recommend this company to anyone desiring an improvement in their hair and scalp. Also, Kiierr customer service is top-notch with an exemplary response time. Lastly, their website is easy to use and has a variety of your favorite products to select from for safe shipment. Kiierr staff works seamlessly allowing you to reach out to customer service at any time. I can confirm that you will receive an almost immediate response and support from Kiierr. This company not only has great products, but they also really do go above and beyond to support their customers.

new to the program. Bought the cap. Unfortunately had a bad battery pack. But, within the day, I was notified that a replacement was on its way. Excellent service and standing behind the product. Much appreciated.

I am extremely happy with the results I have achieved with my Kiierr International laser cap. I purchased my hat in 2018 and have been using it regularly since then. I have seen so much improvement, and if I had not been using it I feel that I would have lost most of the hair on the top of my head. I would highly recommend a Kiierr International cap to anyone looking to restore their hair growth.

The customer service is the best I have ever experienced with any company. I retired from a dermatologist office and I have bought and sold many products. I have used your vitamins, shampoo and conditioner for years. I have one of your first laser caps, the wand and mask. My mom will be 96 in a few weeks and give her the vitamins too. My daughter also uses your serum, wand and ipl. WW The packaging is solid, I have never had an issue with damaged products. The best part about this company is their customer service. They truly stand by their products. I have reached out to them on a few occasions helping me with the use of a product. They are very courteous and quick to respond which in resolving my issues everytime. I trust this company.

My 302 Flex cap has been exactly what I needed for my hair loss. Within only a few months, I noticed significant results!

During menopause, I started losing my hair in a male pattern baldness way. So I tried the Kiierr helmet. I have a group of women over monthly and they all think I’m “cool” to have this device. When they come over, they all want to try it too. I have noticed a big change in my hair growth and thickness. I have used it over 5 yrs. , I have used their shampoo and conditioner, and I will continue to use it. Thank u Kiierr!!

I thhink this might b e worth doing a study with. I have been using a 272 premium cap for about 2 months. In addition to lossing less hair I am a person who has had a lot of migraines. In the last few weeks I have only had a couple of them instead of 2 to 4 a week. Nothing else has changed besides the cap. I wonder if others have experienced this. You may want to check into this???

The Kiierr company is conscientious, courteous, and painstakingly diligent. They stand behind their products and will right any wrong. I will not hesitate to to purchase their products again, and I have no hesitation, whatsoever, in recommending them HIGHLY! I am a very satisfied and happy customer.

I have been using the Kiierr 272 premier MD laser cap since May 2022. I use it for 30 minutes every other day while watching TV or riding the stationary bike. The battery pack allows approximately 4-5 30-minute sessions. I have not experienced any side effects from using the Kiierr laser cap. At first I didn't see much change, but consistency started to pay off. Unfortunately, I had a medical diagnosis requiring radiation and am now on a medication for several years that causes hair loss. I continue to use the cap every other day in the hopes that not all hair will fall out and will help keep some hair and regrow where it has been lost. The cap is comfortable, but I wonder if I should have gone up a size in the cap because it is a little tight and wobbles on my head.

I purchased the Kiierr cap a couple of years ago and I have noticed a considerable difference in my part area of my crown. It seemed as though my part was getting wider and wider in that area and after using the cap, it has filled in again. I also just love to wear the cap because it feels nice on my scalp and it brings me a sense of relaxation at the end the day.

I purchased my Kierr laser cap in 2021 and have been a long time Kierr customer. I started to see signs of hair loss during menopause and decided to try the laser cap. After using the cap pretty religiously every other day it has helped me regrow my hair. In addition, the customer service is excellent! Thank you Kierr!

There is a remarkable difference between my before & after pictures. The cap is easy to use & using it only 30 minutes every other day was a great choice compared to taking another medication. I recommend this to all my friends. Thank you.

Order The ordering process was straight forward. I got my order delivered within a few weeks from ordering. My pet peeve is, they didn't include an appropriate power adaptor for my country, Singapore. The 3rd party multiplugs come with an inherent risk of arcing and loose contacts and are generally frowned upon in my country. Battery Life: Right from the start, the battery life was quite acceptable. For a 30 minute session, it can last up to 5 times when the batteries are fresh and fully charged. Over the past 2 years, the battery life however is less than acceptable, lasting only 2 sessions maximum. Efficacy: There's definitely an improvement in my hair density and thickness. I have gone for an hair transplant earlier and I had very thin hair even from the donor site. In order to avoid losing the transplanted hair, I started using Kiier and the results have been pretty amazing. I do however take Oral Minoxidil regularly and that could have played a part as well. Warranty I paid for a full comprehensive 5 years warranty. When my battery failed, they refused to honour the warranty and asked me to pay for the replacement battery at a heavily discounted rate instead of a full RMA. The rest of it can be seen from my before and after pictures uploaded here.

After six plus years using your cap and DHT shampoo and conditioner, I have substantially regrown much of the hair loss in the crown area. I receive comments all the time from my hair stylist and even my former coworkers, at 70 I was the only one with a full head of hair!

I was a skeptic who thought that using the Kiierr helmet and similar ones were scams. Was I wrong!!! After much research, I decided to purchase a Kiierr 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 Kiierr 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 Kiierr 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 Kiierr 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 Kiierr!! For me, there's no turning back! You'll feel the same way after you've used the helmet. The only issue I've had has been with the battery. . . it stopped working a few times. That was no problem; however, as Kiierr's customer service is responsive, helpful and courteous. They replaced the batteries free of cost! That's one more reason to purchase a Kiierr helmet.

I'm in my early 30s and have been using the Kiierr 272 cap since mid 2022 for early stage androgenetic alopecia and scalp dermatitis. While I haven't seen significant regrowth, it has absolutely helped slow down the rate of shedding over this time and made my existing hair look and feel healthier overall. One unexpected benefit is that my scalp is far less itchy and irritated when I use it consistently. At one point, I stopped using it for a few months and noticed a major increase in shedding and discomfort. This cap is the most important safe and effective tool I've found to fight my hair loss and keep my scalp healthy. Plus, the customer service was really helpful when I reached out about a battery issue. Highly recommend!

My wife purchased this for me five years ago. I doubted that it would work but decided to give it a go instead of complaining about losing my hair. It was easy to use, and within a few weeks I saw results. Since using the cap I have stopped losing my hair, have seen it thicken and I think it as helped prevent my hair from turning grey. My friends, family and even my hair dresser think I dye it but I don't, I credit the cap for this and for my hair being thicker and no longer falling out.

Several years ago, I purchased a Kiierre cap, and I must say that it has significantly improved my thinning hair. Furthermore, their customer service is exceptional, surpassing that of most companies. They promptly respond to calls and emails and consistently resolve issues. As a highly satisfied customer, I am now considering purchasing a red light skin therapy. I am confident that they will provide exceptional customer service assistance and intend to purchase all of my products from them. On Jan 22, 2026, at 8:48 PM, Kiierr International wrote:

The Kiierr helmet seems to work. I also use oral Minoxidil. I’ll let the pictures speak for themselves. First one is before and the second one is after. The reason for only 4 stars is because I purchased in 2020 and it stopped working after 5 years. I was hoping it would last longer. Customer service responds quickly and is helpful in troubleshooting.

Excellent cap that is easy to use, reliable and has give me good results. Trick is to remain consistent and you will see that shedding slows and then some gains will appear. I mix it in with my protocol of minoxidil and micro needling and the three combined have given me great results. I’ve been using the kiierr cap for about 5 years now and have maintained the initial gains I got in year 1. Could recommend more highly.
