Excellent product. Typical status quo shipping time. Competitive pricing.

I am very happy with my Kiierr helmet. I have been using it for several years now. My hair remains fuller than it was when I started. There is a big difference and I notice when I stop using it for some time my hair becomes thin again. I have also noticed that my hair grows faster in general- not just filling in the thin areas. I also recommend the extended warranty. I had a problem with my unit at 4 1/2 years. The company quickly addressed the issue and helped me identify which part was defective. They sent me a replacement part immediately. This has been a very good company to work with.

This cap has really saved my hair! I have been using it every other day as recommended for just over a year. A while back I had suffered from a stress event which left my hair shedding of clumps every day for months!!! I was so distraught and spent hundreds on hair care. I finally did more research and found Kiier!! I will never be without my cap again. My hair is thicker and fuller. You can even see the sides filling in nicely.

I purchased a Kiierr 272 model in 2022. I had just begun a sudden big downswing in hair density, the kind most men experience somewhere in their 30s. I had already been on minoxidil and anti-dandruff shampoo, but it was no longer enough. My dermatologist suggested finasteride and red light therapy, but I was nervous about the finasteride side effects, especially as we were trying for a child at the time. So instead, I purchased the Kiierr and used it ~3 times a week since then, setting reminder alarms on my phone to be sure I didn't miss a session. Within about 6 weeks of starting, I saw a halt to the increasing hair loss, and then a few weeks later, the beginning of some regrowth. 6 months later, my wife randomly commented that the change was noticeable. So for something totally non-invasive, that was all pretty amazing. I've continued using it plus minoxidil since then and have seen minimal additional hair loss, now into my 40s. I even contacted Kiierr support when the battery died, 4 years in and out of warranty, and they were able to make things right. Overall it's hard to imagine how they could have done things better, either in product or service.

I was skeptical at first. But I have to admit my crown is getting fuller. I have a ways to go but I am optimistic about future. The Kiierr cap definitely works. Ben A
