I can honestly say this red light therapy headpiece has been one of the best investments I’ve made for my hair journey. I’ve been using it consistently for several years now and the difference from when I first started to today has been incredible. My hair has grown so much from the roots, feels healthier overall, and I’ve seen such a noticeable improvement in thickness and regrowth over time. What I love most is that this wasn’t an overnight result — it truly came from consistency and trusting the process. I made it a priority to wear it exactly as directed and stay disciplined with it, and the outcome has absolutely been worth it. I still have more growth goals, but seeing the transformation through my progress photos from the beginning until now is honestly amazing. If you’re patient, consistent, and committed, it really does make a difference. I’ve recently added their hair vitamins because you can’t go wrong…. overall I’m impressed, thank you Kiierr!

Hello. I give this product 5 stars because it's super easy to use and has helped me care for my hair. Plus the Support Team at Kiierr is very responsive and helpful. I've been using it for several years and I also referred Kiierr to my aunt who is also using their products. My dermatologist is the one who recommended the helmet to me so I feel it's safe to use and effective.

At 51, I had major hair loss and decided to give Kierr a try. I began to wear my Premier 272 cap for 30 minutes every other day, no matter where I am (the hardshell travel case is great), and I started to see real results in weeks. Four years later, my hair is fuller and healthier than it was 20 years ago. The "before" photo was taken in June 2022. The "after" photo is May 2026.

I have been using the Kiierr 272 Premiere for 3 months now and am beginning to see the signs of new hair coming in. I tried the Theradome for 1 full year and did not see any improvement. In fact, the before and after picture showed further recession. I am optimistic about my results so far and my wife has noticed much less hair falling out once she started using the kiierr device as well. We are happy with the results this far.

I’ve had a very positive experience with this laser cap overall. The device has been easy to use, comfortable to wear, and simple to incorporate into a regular routine. I appreciate the convenience of being able to use it at home without disrupting my day. Over time, I’ve noticed improvements in the appearance and fullness of my hair, and I value that the treatment is non-invasive and straightforward. Customer service has also been responsive and helpful throughout the process, which made the experience even better. I would recommend this product to anyone looking for an easy and consistent option to support hair growth and scalp health.
