Had an issue with the battery. Problem was diagnosed quickly and a new battery was sent right away!

After using the red light cap for a couple of years and loving that, I also used the DHT blocking shampoo and conditioner and have recently tried their new hair dye shampoo. It’s been great so far! I find it much better than constantly dying my roots and it’s a more natural and subtle look that the skunk line I used to have. Kiierr has great customer service and I’m super happy with all the products I’ve tried! The photo is 5 weeks of grow out which usually is a silver line down my part.

The Power Bank for my Kiierr Laser Cap failed after 2 months. I contacted the Company by e-mail and was immediately provided troubleshooting instructions. With no success the Company is shipping me a new Power Bank. . . . . . All this accomplished in same day. Thank you Steven (Service Manager). . . . . . . . Great product and equally great customer service.

I bought a few products from Kiierr. I love them all and have had amazing experiences with this company! This cap works! My hair grew so fast and came in thicker. This is a quality cap and the best on the market, backed by science. I highly recommend! I am feeling 10-15 younger, getting my confidence back! Thank you Kiierr!

I have had this product for 1 year. It does make my existing hair grow faster but the jury is out if I am getting NEW follicles. But I still like it for the FAST growth. I know because I color my hair and now I have to color it more frequently (4 weeks instead of 6) because the gray roots show up much sooner! That said, this review is for Kiierr standing behind their warranty. I received help from Steven, Tech Manager. My battery would not charge past 1 bar, which means you are not getting the full strength of the lasers, per the manual (they recommend keeping it charged between 2 - 4 bars). I thought I would have to wait for a new battery to be shipped. Steven responded quickly, and gave me a couple of solutions to try. The first one worked perfectly. And I didn't have to wait long for a response (2 days) so I didn't lose ground on my treatments! Very happy. Tip, just make sure to save your ORDER NUMBER as they confirm your warranty off of that. My warranty is for 2 years from date I received the cap.
