The cap arrived as promised.

The cap arrived as promised. I purchased the cap on the 19 and it arrived by the 22nd. The instructions were easy to follow. The battery was charged to 75% and I was able to use the cap within a couple of hours. It fit and felt good. Fingers crossed for a positive result.

Professional and Customer Focused

Initially, I had some issues with the product and the process, but the company not only issued me a full refund, they also went a step further by sending additional vitamins to support my journey. I truly appreciate the effort they put into ensuring customer satisfaction, and their professionalism has left me with a very positive impression. They genuinely wanted me to feel treated fairly and happy — much appreciated!

Recommend this red light gear for hair - easy to use and charge

Gear is easy to use and charging is a breeze. It can be used while doing other things as the battery is very portable and I love the mirror on the battery - very useful s. My order for the lowest level type was delayed and I was upgraded for only $75 to the next level hat/cap. I think I am seeing a little more hair growth already after 2-3 weeks.

On April 11th 2023 I got a brain…

On April 11th 2023 I got a brain operation done, where they removed a benign ( good) tumor of 6.5 cm x 5 cm out of my little head. It started with vision loss in my right eye. I could only see about 5-10%. After an MRI of the head, they discovered this “little friend” living in my head, which was pressing on my R optical nerve, and because of that, I was losing vision!No panic!! I had an amazing team of doctors and nurses who took care of me. What was supposed to be a 6 hour operation, turned into an 8h 20 min operation from the time of incision.The neurosurgeon told me that I might have a few issues after the operation, of which my hair not being able to grow back where they cut me open in the hairline, from L ear to R ear. Long story short….. God had other plans….Where I was supposed to stay 5-7 days in the hospital, and of that 1 day ICU, turned out that I stayed 2 days in ICU and I was strong enough to go back home!! I wasn’t allowed to wash my hair in the beginning. Later on with only Johnson and Johnson baby shampoo and conditioner. No coloring of the hair… Weeks went by and I recovered pretty quickly. But all of a sudden, I noticed a lot of loss of hair. Losing hair in huge bundles….! I got scared and in a panic mode….Even worse, when my friend asked me if I was losing hair…. I asked how she knew, and she said that there was a huge “hole” in the back of my head with no hair. So I started to investigate what I could do to help myself!!One of my neighbors was sharing with me, that she was selling these LED light brushes in her salon and with great results.Knowing myself…. I started to investigate many different products and why one product to say yes to and run from the next one.So I ended up on Kiierr.com, after my research. I was happy to find out that Kiierr had Medical grade Laser in the helmet, and that was what I was looking for!!I bought one and started to use it every day. Honestly…. I would wear it a few time longer, after the 7 min beep told me that it was time to take it off. Now the volume slowly came back. What I mean with that is, that you could pretty much see through my hair, like a sheer curtain hanging. Now there is some volume back. Not where I want it to be yet…. But I know it will get better, after seeing from where I came from! I wished there was something that I could use to make it grow faster and longer, because I had to cut it a lot shorter, because of the way it looked…. I miss my long curly hair…. And can’t wait to get the curls and length back!!But if you want to know if this really works…. Don’t ask…. You know the answer already, after sharing my story with you!

Easy online ordering

Easy online ordering. I am also happy with customer service. The registration asks for a photo of the persons hair, and based on the website language I thought that was for the warranty, rather than the 7 month hair guarantee. (I am very sensitive about my hair issues). Customer service reached out to me and addressed the misconception.

Great product

Great product, great price point. Also, the warranty does not require several registration steps upon receiving the laser cap

Just received my Kiierr laser cap…

I received my Kiierr cap just this week so I have only used it twice. I received a personal message after ordering thanking me for my order and letting me know the company was available for any questions or concerns. That was unexpected and very nice. I am looking forward to seeing some new hair growth over the next few months.

There was a slight delay on delivery but Louder was very proactive in ensuring I was informed about status and status changes.
