Great customer support. I received answers to my (shipping) questions almost instantly. Kiierr was able to change delivery times to ensure that I was home to receive my nifty laser cap.

Customer service continues to be amazing. I lost my charger and customer service agent went through everything step by step even when this boomer could have driven anyone in tech crazy.

Easy to use & good customer service

Thus far, I have had no problems with this device. It is comfortable to wear (although it’s good to know that the hat is not “flexible”; rather, it is has a hard shell that fits into the baseball cap cover). I have a sensitive scalp but have had no irritation. Customer service is very helpful (although I did have initial difficulty getting into contact with them, once I did, they were very attentive). Easy to register the device (don’t forget to upload your before photo)! Great money back guarantee in the case that you do not see results (no restocking fee if you document your progress with photos). All in all, a great experience thus far.

Very easy order process

Very easy order process, communicated well about shipping times, and the instructions that came with the product were easy to follow. They also sent a personalized video of support, thanking me for my purchase and offering customer support if needed.

I ordered and received my 272 cap last…

I ordered and received my 272 cap last week. Arrived within 4 days of order. I ordered this as an update to replace my
IGROW unit that had stopped working due to a failed connector the week before. This cap is so much more comfortable to wear, as I don’t have to balance it on my head (limited mobility) like the IGROW helmet. This cap has many more lights, and the coverage on my scalp is much larger, so I am hoping this will provide improved growth support to the rear crown portion of my scalp. It is also easier to wear during treatment since the cap cord plugs into a handheld battery pack, as opposed to connecting to an outlet. This sense of freedom is most appreciated. Looking forward to excellent results. Time will tell.

The device took 20 days to arrive, mostly due to ‘processing time’

The device was eventually delivered but it took 20 days from the time it was ordered, which in my case meant that I won’t be able to use it for a couple of months because I am now abroad.

The three stars represents the slow/lacklustre delivery. I think the company needs to be more upfront about how long it takes to arrive. The headline “two day shipping” leads one to think it would arrive in a week or so, although if you drill down into the finer print it says there might be some delays because they are busy. I didn’t see that until after I had placed the order but either way 20 days is a relatively long time. The shipping itself appears to have only taken two days from when it was ‘processed’ but it took about 18 days after they received the payment to process it, which I find a bit odd.

I also think that Kiierr should require a signature on delivery because these days packages can easily get stolen.

Eventually when I actually have the device in my hand (when I am back from abroad) I intend to use the device and if it works I will increase the rating but the shipping experience wasn’t good. There was a customer service rep who was polite so I give them credit for that at least.

We’re very sorry for the delay you experienced. This was due to a temporary slowdown in processing times, and we’ve since resolved the issue to prevent future delays. We truly appreciate your patience and are glad the device arrived safely. We look forward to hearing about your results once you begin using it :)

Woww

Wow, these diodes are bright! I received my cap within a week and the financing option with affirm made it an easy decision to prevent my hair from thinning more. I have been using the cap for about 2 weeks and my wife says its already working. I have photos from the day I began using it. Only time will tell from here.

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.

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.

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.

Réponse de Kiierr Hair Growth

Hello! I understand your concern and I’m sorry if this wasn’t made clear. The registration and photos are only required if you choose to participate in the 7-month growth guarantee. They are not needed for the 2-year product warranty. Your 2-year warranty is automatically valid starting from the date of delivery and does not require any registration.

If you ever need service for a defect or repair, your original purchase will be all that’s needed. No photos or proof of hair progress are required for that. I hope this clears things up, and I truly apologize for any confusion caused earlier.

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!

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!

Thieves and a Robotic CS

Do not buy from this company. They sell products that are never in stock and expect you to wait months and hope you forget! They never keep you up to date on status of orders and their customer service is abominable! Every reply is less than 5 words and unhelpful or lies! Stay away from Kiier you can get these supplements from another vendor easier and cheaper on Amazon and actually get the product!

I order the hat and it was allegedly delivered. I never got my package. I tried talking to customer service. They won’t talk to you over the phone. Only email and they pretty much brushed it off. I lost around $700.
Never got a replacement or a refund.
Do NOT waste your money.
Get your cap from a different company.

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.

The hair cap has helped so much with hair growth. I have lots of baby hairs, so I know it is working. The Kiier cap is as good as Rogaine only much easier to use (and less messy). I would totally recommend the hair cap for hair growth. Also, the customer service from Jami is always 5 stars/excellent!!! :)

Definitely try this!

This has been a great addition to my beauty routine. As a woman in my late forties, I purchased the cap when I noticed patches of thinning hair which made me feel very self-conscious. I tried other topical products, but they didn't do much. I have been using the Kierr cap for around 4-5 years now, I have noticed I have more even hair growth in the areas that concerned me (temples and top of head). I feel much more confident. Customer service has been great also for anything I needed to reach out for.

Kiierr 270 MD and the face masl

I purchased Kiierr 270 MD and the Kiierr face mask in early July (living in BC Canada) and received them in about 10 business days. It was all smooth and easy. I've been using them for about two weeks, and expecting to see initial results in 4-5 months.
