A lot of people giving reviews seems to be fixated on speed of delivery and customer service. This makes me think some reviews here are dubious? Does the thing work!? Surely no one would care if it took 3 weeks to arrive if it solves an issue that can be incredibly depressing

Kiierr Hair Growth Absolute delivers
I began losing my hair 20 years ago and have tried everything vitamin pills, oils, even a few plugs of transplants but nothing has ever delivered the promised results until I found the Kiierr laser hat ! It took about seven months before there was noticeable results! But I was so happy to find a treatment that delivers on its promises . My journey is long but rewarding ! I am excited ! RF
Excellent Customer Service
So far so good! My husband just got it so we don't know if it works for him yet, but the customer service has been great!

Great product
Great product, and great customer service. They were so prompt with emails back.
Great communication
I have received my cap in three weeks as I am in Australia. I did contact them and they responded quickly ,good communication. I have started using my cap ,so far I am happy with the product, hopefully I will achieve my goal. Quality off the cap is good, hopefully well worth the money as it is not cheap.

Came in a very nice package and easy to set up and get started.

The customer service was invaluable and friendly and assisted me with upgrading my cap
The Sales Manager support from Kiierr Hair growth just gets better
I have been emailing with the Sales Manager from Kiierr today and yesterday. She continues to offer the kind of outstanding service, and support that you wish every Sales dept in every company would offer. She offered understanding, acknowledgement, and possible solutions for my specific situation, with great thoughtfulness. She knows how to be a great human being, let alone a tremendous representative for Kiierr Hair growth. So grateful, and so impressed!
Great product!
I'm early in my hair re-growth, but the Kiierr 302 is really easy to use. The battery holds a charge for about 5 days. I use the 302 for 6 minutes a day, and I'm looking forward to getting more hair in my thinning areas.

Easy to navigate site. Helpful chat while making order. Fast shipping and the product arrived as described. The cap fits well and seems to be working as it should.

I purchased the Kierr 302MD
I purchased the Kierr 302MD. The cap has been super easy to use and only takes 6 min/day, so it has been easy to incorporate into my daily routine. It was very simple to use out of the box. The battery is lightweight and holds a charge for 5-6 uses. I did not give 5 stars because the cap took a few weeks to arrive, and Kierr was not clear about how long delivery would take. Everything else has been excellent and it was easy to apply to my HSA account.

So far so good!
Great experince so far. I let Kiierr know I did not receive the headband and it was on back order. Then i received it about a week later. So far, great customer service! Too early to tell on how well this will work.

No hair growth improvement & shameful customer service
Purchased the model 272MD cap Jun 24, 2023 & received it July 2023; submitted a scalp photo (hair loss area) & wore the cap per the instructions. I had a previous cap (different maker) that had a fraction of the infrared diodes of the new, so was not worried about the money-back guarantee as was confident I would see results. Almost 1.5 yrs later, no noticeable improvement.
Emailed Kiierr customer service Feb 2, 2025 with original before AND after cap use photos; rec'd a reply asking if I was seeking a refund; I sent a Feb 10 reply stating I believe the cap isn't working properly & would like to have the cap tested and my callback number & availability; rec'd an email reply ONLY that "if it lights up, it's working properly" (a ridiculous assumption); called them March 4 (no person to person customer service when calling them) & asked for a callback.
To this date, I've never heard back from them.
I would encourage anyone considering red light therapy to check out hair loss clinics in person to confirm what tried & tested brands they use or recommend.
Everything indicates high quality
My shipment arrived on time.
All of the packaging that came along with the product was of very high quality which indicates that the company is not trying to make money on a quick basis & is committed to ensuring that their customers know that they are dealing with quality people.
