Kiierr Hair Growth Recenzje 

Throughout the research time period, the Q&A, the delivery, and the after sale, they were always there and always kind.

My order was delayed due to them being so busy, but customer service was super prompt in answering questions and keeping me updated. The cap itself works well-it's a little more generic than I expected, and the fabric "baseball cap" looks absolutely ridiculous on me. It is not inconspicuous as they mention, and I will not leave the house with it on. I don't even like other family members to see me wear it. It's difficult to tell if it is actually on because the lights only work if it is on your head. So I always check in a mirror to make sure it is on after I've turned it on. Also, if the battery dies mid-session, you have no idea until after you sit there for over the session time and no beep occurs. I've only had it a few weeks, so time will tell if it was worth the money. I do wish I had read the fine print on the warranty registration because this is such an expensive product. You need to register with a picture not only for the money-back guarantee, but also the warranty!! There is a limited window after the 7 months to contact them as well.

The process is straight forward. Just 6 minutes a day at a regular fixed time. I chose the 272 dualwave. This model was specially created for someone with a moderate budget. The high end model was a little pricey for me, whereas the cheaper model required wearing the cap for 30min a day which I could not afford. This model just required 6 minutes a day, easy peasy. I appreciated that an email was sent to me once the order was made encouraging me to decide on a regular time of the day to have my 6 minutes of treatment, before the cap arrived. The therapy does not hurt. I can feel my scalp warm up towards the end of 6 min. Do consider getting this model yourself!

So far, the initial sending of product and communication has been really good.

I received the product promptly and the package tracking was very good

Came delivered quickly. Seems very quality cap. Fit is snug and 6 minutes is easy each. Have seen improvement in first month

Super easy and quick to use the 6-minute daily sessions make it simple to stay consistent without disrupting my routine. The cap is comfortable, well-designed, and feels like a high-quality device backed by solid technology.

I bought the laser hat in the 1st of Dec 2025. Reading reviews here I also was tricked by their 2 day postage service. They do have fine print due to busy take 10 days. We are way past that now. Not a fan of fine print tricks by companies. Now I have reached out and no replies. They are happy to keep sending spam emails to buy more stuff. In Australian dollars this has cost me over $2k. That’s not small money. You expect replies to emails, updates on postage or delays. Giving it one more day and will go through PayPal get my money back and buy the irestore hat like I should have. Stay away from this company
Update: they did finally reach out say would cancel order. Then silence again. No answer as to when. Or how being paid. I just got money back through PayPal.

I just bought this last week and am very happy with the customer service and the quality of the product. Over time will see the results, they do offer cash rebates for leaving reviews so worth keeping that in mind when reading all these.

I just received my Kiierr 272 laser cap and my experience with the company has been great so far. Ordering was easy, shipping was prompt, and the packaging felt premium and well thought out. The cap itself is comfortable, solidly built, and clearly high quality.

Kiierr does a great job with clear communication, education around the product, and standing behind their technology with a strong warranty. Everything from the setup to the instructions felt straightforward and professional.

I’m excited to start using the cap consistently and see results over time. So far, the experience has been smooth and I’m glad I chose Kiierr.

My Kiierr 272 Premiere arrived earlier than expected. That's a good start. I've used it a few times since I received it. Set up was easy, Charge the battery, (mine was already charged), then plug the cap in and Press start. It beeps every 10 minutes until it hits 30 minutes, then it turns itself off. I like the recommended use of 30 minutes every other day, as opposed to having to use it everyday. The device fits the top of my head well, hitting all my thinning spots (Crown and receding hairline). The baseball cap that sits on the actual device looks kind of funny. I will not be wearing it in public. Other than that, the Kiierr 272 Premiere seems to be made pretty durable and feels warm and relaxing when being used. I haven't used it long enough to see any hair growth yet, but I have high hopes.

*Updating this review* I strongly regret purchasing from this company and wish I'd read the critical reviews more carefully first.

I received a Kiierr cap that doesn't fit despite my head being well within their advertised sizing. The product is much smaller than specified and sits awkwardly high. After immediately contacting customer service with requests for a refund and support, I have received no response to any of my attempts at resolution.

The cap I received is unbranded and looks nothing like the marketing photos. It appears identical to generic Chinese white-labeled products available on xxxx for a fraction of the price. When I raised this with the company, their response was that "customers prefer" unbranded caps - a claim I find impossible to believe given the premium price point.

Examining the review patterns raises serious concerns: most five-star ratings come from accounts with only one review, posted shortly after purchase. There's minimal evidence of long-term use or actual results, and hardly any genuine user photos. Just generic praise about shipping and ordering that tells you nothing about whether the medical device actually works. Meanwhile, negative reviews about fit, sizing, and returns receive no meaningful reply or resolution.

Kiierr charges premium prices for a product they refuse to support or service properly.

Based on my direct experience, I cannot recommend this company due to their non-responsive customer service and what appears to be a rebranded generic product sold at a significant markup.

Also notice the brand new review from a customer who has owned the product for 1 month, who claims it fits his large head.

I don't think that that review is a coincidence. Do what you will with that information.

When you write and ask a question or have a concern this company is quick to write you back. I had a few questions and each time within the SAME day I got an answer. I am sure sometimes they may have to investigate your question, but on all my questions, I got fast responses. Tell me, how many companies do you know that has that reputation.

The item arrived in pristine condition but as it arrived from USA, I had to go out and get a USA to UK adapter.
I charged up the battery and used it for the first time, for 6mins, all good and very high quality product.

The device came on time and works as advertised.

I could not give it 5 stars yet. So far so good though. I just received the 272 Dual Wave Laser hat several weeks ago so I have not seen its hair growing affects to date, but I do know that my right knee felt a little pain i.e., tweaky so I used it over my knee and it has seemed to have recovered. No more pain, so it indicates to me that the laser is working. More details to come on the hair growth side in the future.

I have a pretty big head and it fits me well. Ive only been using it for about a month so I have a while before I know if it actually works. I'll update the review after a few months. I actually find it relaxing to wear and nod of sometimes.

I wrote customer service regarding the size of the hat which sits rather high on the crown of my head. The ad says the 272 premier hat is 23 or 23.5 inches in circumference. In reality they measured the outside perimeter of the hat. The actual inside perimeter seems to be closer to 22 inches. Mt head measures 23.5 inches and it concerns me that the hat sits high on my head and although I asked customer service about this, 5 days later I have received no response.

Product arrived in a timely manner. I appreciate the opportunity to guarantee hair growth.

I really enjoyed using this, noticed a lot of thickness along my hair line! Very relaxing to use too!
