After using the red light cap for a couple of years and loving that, I also used the DHT blocking shampoo and conditioner and have recently tried their new hair dye shampoo. It’s been great so far! I... Voir plus

The website is user friendly. Easy to find their research and confirm their claims. Product is easy to use and set up. Length of treatment is reasonable. Good rebate offer if needed. Took two weeks to deliver the product after ordering.
Amazing customer service and the product works. Been a customer for over 7 years!! Happy customer!!
Great product, and great customer service. They were so prompt with emails back.
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.
The customer service was invaluable and friendly and assisted me with upgrading my cap
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!
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. 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.

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.

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.
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.

I bought one of their laser hats. It was too small for me, and for some reason wearing it made me intensely nauseous.
I asked if I could return it I was told I would have to use it for 7 months first (which of course I can't do since I could tolerate it for less than a minute).
The also asked me if I wanted to pay them another $300 for a bigger hat.
UPDATE: After 2 months I have finally gotten a refund, which seems to be entirely due to publicly shaming them here.

Réponse de Kiierr Hair Growth
Excellent customer service. Delivery was efficient and very easy to use. I am excited for the potential results.

Réponse de Kiierr Hair Growth
Personal customer service that answered my questions prior to purchase and continues!
Thank you!
