Started using the Kiier Laser Cap in 2021 after losing a fair amount of hair due to Covid 19. Saw significant improvement after 6 months, and with consistent use of the laser cap over the last several years, my hair is noticeably fuller and healthier. I really believe the Kiier Laser Cap made a difference in my hair growth and would highly recommend Kiier.

After years of use, my laser cap suddenly stopped! I wasn't sure if anything could be done but I emailed Kiierr customer service. Within a few hours, I had a reply and suggestions to diagnose the problem and find a solution. To my delight, the cap is back in service and it never left my house! I would rate the service as exceptional.

I've had the 272 diode cap since March of this year. Great product I have significant hair regrowth. Recently ordered the face mask. The products from this company are excellent. Plus the customer service is above and beyond. They get back to you exceptionally quick and always make sure your issue is solved. They actually care about their customers. Thanks Kierr. So glad I bought my cap from your company and not somewhere else.

I have been using Kiierr hat for about a year. I must say that Kiierr's after sales support is excellent. There was some technical issue with the hat. Support department called me and checked the hat over the video chat. They sent the replacement right away. After using it for a while I think my hair looks healthier now.

I purchased my Kiierr laser helmet sometime in 2021.   I only used it occasionally for the first few years and didn't get much from it which was my own fault.   About a year ago my hair was looking terrible so I decided to buckle down and use it consistently for 20 minutes at a time, 5 days per week.   After 6 months I noticed a considerable difference both with new hair growth and strengthening my existing hair.
