How Kiierr Laser Caps Work
No tech skills needed! Just wear the cap and let the FDA-cleared low PureLaser™ Technology stop the loss and regrow your hair, whether you’re at home or on the go.
Hair Loss Stops
In the first few weeks of using the cap for 6-30 minutes (depending on the laser strength in our caps) every other day, you’ll notice less hair loss as the low-level PureLaser™ Technology wakes up your hair follicles and stops them from shrinking due to Androgenic Alopecia.
New Hair Starts Growing
As you keep up with your routine, you’ll begin to see new hair filling in where it was once thinning. The laser light increases blood flow and delivers all the nutrients your hair needs to grow stronger and thicker.
Enjoy Thicker & Healthier Hair
After 7 months of consistent use, you’ll finally see what you’ve been waiting for: thick, full, and strong hair covering the areas that were previously thinning or bare. To maintain these amazing results, keep using the cap regularly.

I feel like myself again!
Kiierr's laser cap has been amazing! You can tell the difference in the volume of my hair since starting to use it. I've been using it since 2021. I had tried many other products and this has been the best one. It's definitely worth the purchase.

Seeing a difference especially at temples
I've been using my laser cap faithfully for 4 months and am really starting to see a difference in the fullness of my hair. I have lots of new growth at my temples and my part is beginning to fill back in.

Good product and service
My experience with the Kiierr cap has been good. I have also purchased many supplemental products including shampoo, conditioner, vitamins, and hair cream many times over since purchasing the laser cap.

Seemed like it was too good to be true
Ive been using the laser cap for 5 months and it has made a huge difference. I’m getting older and the hair loss made me feel even older than I am. After using the cap I feel like I look years younger. I was hesitant to purchase it because it seemed like it was too good to be true. But I called Kiierr and talked to a very nice and

Details
Kiierr laser caps, powered by our exclusive PureLaser™ technology, utilize only high quality medical grade laser diodes (no LEDs) to deliver precise, effective LLLT at 650 nm for optimal hair regrowth.
With options of 148, 272, or 302 diodes, and total power outputs of 740 mW, 1,360 mW, and 1,510 mW respectively, Kiierr caps offer targeted stimulation for fuller hair. Simply use the 148 and 272 models for 30 minutes every other day, or the 302 model for 6 minutes daily, and start seeing results in as little as 6–8 weeks, with significant improvements typically visible within 4 to 7 months.
How It Works
This advanced, FDA-cleared LLLT technology penetrates the scalp to stimulate hair follicles at the cellular level, enhancing blood flow and nutrient delivery to dormant follicles. The result is a revitalized scalp environment that supports natural hair growth cycles, promoting thicker, fuller hair that’s clinically proven to be effective. With over 100,000 satisfied Kiierr customers and a money-back guarantee, there’s no reason to wait. Experience the transformation for yourself and watch your hair thrive!
