pure laser technology (2025)

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.

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!

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!

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.

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.

Recommended by my doctor!

I suffered from a mold exposure that caused excessive hair loss, and this treatment was recommended by my doctor. With continued use of the cap, the vascularity of my scalp has improved. The cap has helped significantly in promoting new hair growth.

Reversed my menopause thinning!

Noticeable menopause thinning led me to try Kiierr’s hair cap. After using it consistently three times a week for several months, I began to see real results. My hair started growing back. Even my friends & hair stylist noticed the improvement!

I love my Kiierr cap!

I use it faithfully and have really seen a difference in my hairline. It was receding on the sides, temples and front, but has definitely stopped and is actually filling in with hair! I would definitely recommend a Kiierr Cap

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.

This cap made me look younger!

After 5 months of using the Kiierr Laser Cap, my hair is fuller, and I feel years younger. I was skeptical at first, but after speaking with their helpful team, I decided to try it. To my surprise, it really works! Plus, their customer service is fantastic. Highly recommend!

Significant hair growth!

I have been using the Kiierr Hair Restoration Cap for the past 18 months. I have received significant hair growth. Attached are my before and after photos showing the hair growth. I highly recommend the Kiierr Cap.

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.

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.

It really does work!

After using the Kiierr laser cap, I have regrown a large amount of hair. I am so happy with my results and plan to continue use forever! If you are considering Kiierr, I definitely recommend it. It really does work.

The Kiierr cap really worked for me!

I purchased the Kiierr cap 4 years ago. I was losing a great amount of hair every time I shampooed. The cap really worked for me. I recently went to my dermatologist and mentioned the cap & he said that “good laser caps really do work!”

Noticeable hair growth with Kiierr!

I was skeptical at first, but after weeks of using the Kiierr Laser Cap, my hair became thicker, and new growth was visible. I’m convinced it works and will keep using it to maintain my results. Thank you, Kiierr!
