The service team at Kiierr is super responsive and helpful!

My husband and I have been using our Kiier cap every other day as recommended for a year and a half! We see a lot of new hair growth around our faces and our overall hair thickness has increased! We love our Kiier cap and happy with the customer service we have received.

I've had a great experience with Kiierr! The package arrived beautifully and shipping was super fast. I started using the laser cap two years ago, 3–4 times a week for 20 minutes, to address thinning in both corners of my hairline. Over time, I've seen significant hair growth and feel so much more confident. Highly recommend!

I have been using a Kieerr cap for a couple years now. The hair on the crown of my head had been thinning for years. After a few months of using the cap, I noticed new hair growth coming in and less shedding of my hair. It has filled in a lot more than what I previously had, and not shedding nearly as much. I am quite happy with the results of using my Kieerr cap.

Been using Kiierr laser cap for a few years—definitely made my hair thicker and fuller. Right after using it, helps take out the frizz. It works great as an addition with other haircare routines and I use it every other day to keep up the balance with some breaks of not using every other few months.
