I could not be happier with my results
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!!)

i was concered with possible hair loss since my father was half bald in his mid 20's. 4 years ago I noticed some thinning in the back of my head. I purchsed your product and used it per instructions for a few years. My barber and say a thickening of my entire head and the small thin spot was filled in. I have a full head of hair ever since and am a believer in the product.

I’ve been using this laser hat for the last 5 years religiously to help regrow my hair and I’m super happy with the results. This device stimulates hair follicles to grow and when used in combination with minoxidil it gives fantastic results. I’ll be using a laser hat for the rest of my life! Thanks Kiierr!

After three weeks of researching the science and customer reviews I choose Kiierr.
When I ordered online I made a pricy mistake and the company more than corrected it for me.
I am truly grateful and will have warm heartfelt feelings each time I wear my Kiierr laser cap.

Finally getting my hair back!!!!
These days it seems like the most products are poorly made using cheap materials, They don't look or function as advertised. Customer service by phone is usually someone reading responses from a script. Email often does not provide very helpful answers that address the question. I was reluctant to purchase Keiirr Hair Growth Laser cap based on past experiences. The product sounded too good to be true. But I read a lot about laser therapy for hair growth and, although skeptical, I decided to try it because I was desperate to find a solution to my hair loss I am 64 and experienced nearly 4 years of non-stop chronic stress. My hair had fallen out to the extent of clogging the drain, filling my hair brush, and was all over my clothes. The part continued to widen and started to see my scalp. Once the stressors were finally eliminated I thought my hair would grow back. After two years it still hadn't. I spent a lot of money trying every supplement and product I could find. Nothing worked.
Then I discovered Keiirr. The results from using their laser cap was amazing. I started seeing baby hair and my part is beginning to fill in. This product is well made and lives up to what the company says. I used it every day and not had a single problem with it. The cap so easy and convenient to use that I never miss a day. I can run errands while wearing it. Plus Kiierr customer service is terrific. They are responsive and truly care about providing a great customer experience. I tried to think of some constructive criticism but I've come up empty handed. I'm just excited to look at my hair (instead of avoiding it) and see how its grown. I'm even more excited to finally get my hair back. SO glad I tried Kiierr. I had given up. With Kiierr, you don't have to give up. It really does work! THANK YOU X 100 KEIIRR!!!

I've used Kiierr products for years now! I love the vitamins, shampoo and conditioner and the laser caps! I have actually purchased 4! I have chronic hair loss, which means I'll practically go bald in different areas up on top and then it grows back.. over and over again. I was diagnosed with Talogen Effluvium in 2020 thanks to COVID. My hair was thick and curly and had been below the shoulders and in just 3-4 months it was up to my ears, with bald spots all through my scalp. Thats when I bought my first cap. Slowly but surely it grew back! It's just above my shoulders but thick again. I bought a cap to leave at my daughter's house, who lives in another state, and have upgraded twice during their awesome sales events! Their customer service is the best! FAST response, FAST shipping and GREAT products!

Received as a birthday gift
Received as a birthday gift, started using May 30th, 2025 havent missed a day yet. Use cap for 6 minutes followed by brush of 10 minutes. Very easy to use only 16 minutes a day, definitely making a difference.

272 Dual Wave - Well made with accessories
Just received my 272 dual wave unit. Shipping was fast and it came very well packaged. This unit comes with the rigid storage case as well as a battery and charger. The laser LED units are contained within a separate shell that gets inserted into the cap. This allows for washing of the cap if necessary and also makes the unit more durable. I'm looking forward to giving this an honest try, especially since it's only 6 min a day. It came with a 7 month hair grow guarantee, so it's really low risk. You have to submit a before photo when registering your unit to qualify. If I can get even modest improvement, it will be well worth the money spent.

The 7 month growth guarantee really made me feel confident in trying this cap out. Knowing that if it didn’t work I could just return it. But the results were actually amazing. My hairline is back to what it was before and I could not be happier. This came from 5 months of consistent usage every other day.

Just had the cap several weeks, but its easy to use. Looking forward to great results!
I was skeptical at first
I was skeptical at first, but after consistent daily use I’ve noticed my hair feels thicker and healthier, with subtle but clear improvements. Definitely glad I gave it a try.
Kiierr 272 laser cap review
Although the laser hat did not grow new hair it may have slowed my hair loss. I believe it will regrow hair with some forms of hair loss.
They have always been quick to provide support and even extended their guarantee window in the hopes later results would be achieved. In the end, they were willing to provide a full refund. They stand by their product.
Great Support Team
Kiierr has been wonderfully responsive and supportive. I’m excited to start my hair growth journey with their cap and other treatments!
Give it a try
Product is easy to use. they offer rebates and a growth guarantee. Been using for 2 weeks, will update in about 6 months.

I ordered one it didn’t fit they said they would send me a larger one and they haven’t 4 weeks later the company is a scam and won’t refund my money or anyone’s money outside of narrow guidelines they can wiggle out of! Do not trust this company buy from another company

It’s pretty easy to use, would have like to not have to walk around with a battery pack though

Received promptly. Easy to read instructions. I had a bald spot from cryosurgery with 50/50% chance of regrowth as per Dr. I have been using cap for 4 months and have about 1.5” of hair on the once bald spot!.. seems to work as my hair has always grown very slowly.
