Hard to Believe?
See for Yourself.

It’s a worthwhile investment!
I started using my Kiierr cap almost 4 years ago at 63. After the first 6 months or so, I noticed that there was less hair caught by my shower drain strainer than in the past. My temples and the thinning hair on my crown have filled in.

Frank L

My hair is thicker than it’s ever been!
I suffer from hormone-related hair loss. It was devastating to see my hair become thinner & thinner. I have been using Kiierr for 10 months now. At first I was skeptical (was this too good to be true?), but I was astounded when I started seeing growth after 6 weeks!

Denise C

My hair is a lot thicker!
Thicker hair on my crown has been the most noticeable change since starting with Kiierr. Over the last several months, my hair has visibly thickened, especially in areas that were previously thinning.

My hair is thicker and fuller!
After contracting COVID, I experienced severe hair loss. I tried the Kiierr Laser Cap and after 5-6 weeks, new hair began growing on my bald spots. By two months, my hair became thicker and fuller. After three and a half months, I was thrilled with the results and highly recommend!

Marsha W

Nothing worked until Kiierr!
After spending 10 years trying other hair growth products, I heard about the success of laser therapy after researching. As you can see, during the 3 year process of using the Kiierr Hat, I could see remarkable results after only 6 months.

James R

The Kiierr Cap really helped!
I've always had thin hair in the crown but 3 months after having Covid, my hair started coming out in handfuls. The Kiierr cap was what helped along with Kiierr’s shampoo, conditioner and biotin.

Kiierr saved my hair!
At 65, my hair started falling and I was nearly bald. I didn’t want a transplant and couldn’t see a doctor during COVID. I tried Kiierr, and it truly helped. Thickened my hair and stopped the loss. I recommend it to everyone facing hair loss.

It’s a game-changer for my hair loss
Easy to use cap which I have been using for about 5 years now, every other day. My hair strands have become thicker & have less shedding. I would definitely recommend the Kiierr cap, especially due to the scientific backup.

Vincent R

Highly recommend all Kiierr products!
The laser cap definitely helped regrow hair over the balding spot on the crown of my head and on my thinning/receding front hairline! I also use the Kiierr shampoo, conditioner and vitamins. I highly recommend all Kiierr products!

Amazing for male pattern baldness!
I highly recommend this product to anyone with hair loss. Male pattern baldness started in my 20s with a receding hairline and thinning crown. I have seen awesome results with red light therapy and it was worth every penny.
