For many years, I accepted the progression of male pattern baldness based on genetics was an inevitable part of life for most guys. In 2022, I decided to give a Kiierr laser cap a try. At the time, my bald spot was quite apparent and growing. I did not expect the cap to regrow all the lost hair in the bald spot. Based on what I had read about hair restoration, I waited too long and hence did not think that was realistic. Using the cap as directed, I now have some fuzzy downy strands of hair in the most problematic area (image 1). However, and more importantly, the cap has significantly slowed the progression of male pattern baldness. I have maintained a reasonable hairline when viewed from the front, which as my hope (image 2).

We ordered the hat for my father who's hair was thinning. He was reluctant to try it (at first) but then started using it as instructed and was consistent. Lo and Behold at the age of 78 years old his hair was growing back! The hat works and it is really easy to use as he would sit and watch tv with it on. We highly recommend this product.

Attached is my before and after, this is Jan. of 2020 on the right and Nov. of 2025 on the left. I am obviously very happy that I purchase the Kiierr cap and the results you see speak for themselves. I would hate to see where my hair loss would be without the Kiierr cap. It is wellworth the money and a simple, easy and effective way to help with hair loss.

I am definitely a satisfied and longtime Kiierr customer since March of 2022. My Kiierr cap has been easy to use and very comfortable. It definitely helps me minimize any hair thinning and loss, and aids regrowth. I have found it to be a important tool in my hair regrowth journey. I recommend it.

I have been using Kiier laser cap since March 2022. I am happy with the product and the service from the company. After about four years of continuous use, the battery started having a small issue. The problem was resolved to my satisfaction as soon as I contacted Kiierr. I would say the product and the company both are very reliable. They have my full confidence.

My wife entered menopause a few years ago and she started to have hair loss. She saw a dermatologist in our area that ordered lab work for wife. After results came in, nothing unusual came up. So, the dermatologist mentioned that my wife could try Kiierr laser cap as an additional help for hair loss. So, we bought the cap in 2021 and my wife (and I…) have been using it every other day. We’d say that this device has been helping us with our hair. My wife feels that she has much fuller hair than before and, in my case, I feel that the use of the laser cap has slowed down my thinning hair process. Thanks. Paulo Borges

I use the cap as directed and it's easy to use.

The results I achieved with regular use of the cap were quite remarkable. The regrowth is not quick but it is consistent. It took about 3 months of regular use to start to see results but it was worth the effort. I would highly recommend this method. It works! And stop putting useless and expensive products in your hair. They don't work.

I have been using Kiierr Laser from November 2020. I have used the cap, the shampoo and conditioner and the supplements all this time. When I started I was combing out hair and my comb had hair on it. After I used the Kiierr products, the hair stopped coming out and it felt stronger. My barber noticed a significant difference and mentioned it me. I have been so thankful to find this produce and the help it has provided.

I could not be happier with my results. They're truly unbelievable, and I never thought they could have been achieved in my case. I have never had a fuller head of hair than I have now. I started using their shampoo and conditioner, which now are my favorite products. Thank you so much, Kiierr family, for your excellent product and customer service (Jami is the best!!)

Dear Kiierr, I just want to thank you for your product. I have been using the laser cap 302 for over 6 months now and I have seen drastic differences. I travel quite a bit for work and I always make it a priority that I bring my Kiierr on planes and train. The 6 minutes a day is quite convenient and goes by very quickly as I am normally on my phone or reading a book. Thanks!

I have been using a Kiierr laser cap and hair supplements for five years now and I have seen such a difference I will never go back!

I’ve been using this laser hat for the last 5 years religiously to help regrow my hair and I’m super happy with the results. This device stimulates hair follicles to grow and when used in combination with minoxidil it gives fantastic results. I’ll be using a laser hat for the rest of my life! Thanks Kiierr!

My hair had been falling out non-stop due to. 3 years chronic stress. My part continued to widen and I started seeing my scalp through my hair. My hair clogged the drain, all over my clothes, and filled my hair brush. I used to love my hair but I began to dread looking in the mirror. I'm 64 so it was probably only going to get worse. Seemed so ridiculous feeling depressed over something so little compared to other people's problems. But thats what I felt. I spent a lot of money on supplements, exercised, ate the right things, and tried every product that sounded like if would be at least somewhat effective Nothing worked except a serum from a human bio compounding pharmacy specifically tailored to clients. It required a prescription. But results were negligible and cost way too for the outcome. I stopped using it. I gave up and turned to baseball caps and wigs. Was reluctant to purchase a Kiierr Hair Growth cap. Sounded too good to be true but had read a lot about laser therapy for hair growth Decided to try it and I am SO glad I did! Baby hair is growing, and my part is starting to fill in!! Now I'm excited to look in the mirror every couple of weeks to see how it's grown. Kiierr cap is so easy to use. I can take and wear it anywhere. Even running errands, so I'll never miss a day. This product actually works!!!! For realz. A lot of products are poorly (cheaply) made. They either break, or there's some other problem. I'm impressed with how well Kiierr is made. I haven't had a single problem. THANK YOU KIIERR!!!!!

I am amazed at how well the Kiierr laser cap works! I have stopped losing hair and continue to grow new hair. I definitely noticed a change after four months of use. I recommend 100%.

The personnel at the Kiierr laser cap company are the most helpful and service minded people I have ever purchased an online product from. From ordering and purchasing our first Kiier laser cap to purchasing extra batteries for the laser cap. There was never any hold up or lag time concerning getting a response to my email inquiries, ordering the items I needed to the items being shipped to my home. This was also the first online company I have had follow up emails for some of my inquiries.

I used my cap for two years and people, including myself, noticed my was getting thicker. The cap malfunctioned and i kind of forgot about it for a a year. Now i notice that my hair is thinning out again. I am getting a new cap and i am very excited to start using it again. This time i will document it to share with others. Had i realized how well it was working i would have never allowed any lapsed time. My rating would have been five star accept it did malfunction, but Kiierr is standing behind it.

I've been using the 302 MD Ultra for about two weeks. It's too soon to make a report now, but I'm looking forward to sending a positive report in the future!

I purchased the Kiierr 272 cap in april 2021 as a birthday present for my husband. The first cap that I received was too small for his head, I contacted Kiierr and customer service quickly sent me the bigger size one. My husband has been using it as directed and I noticed that his hair is thicker and healthier. The hair loss was basically stopped in its tracks, and I have observed new hair growth. After over 4 years of use I can say that I am very satisfied with the results.
