FEATURED IN
DHT shrinks follicles and cuts off their blood supply, leaving them weak and unable to produce thick, healthy hair.
Kiierr's laser therapy fights back by boosting circulation at the follicle level. This delivers a surge of oxygen and nutrients that help repair DHT damage and restart the growth cycle.
The result is stronger, thicker hair without drugs, needles, or complicated routines.
Recharge the “Battery” Inside Your Hair Follicles (ATP Boost)
As we age, our follicles don't die, they run out of energy. Blood flow slows, nutrients decline, and DHT further weakens the follicle by shrinking it and restricting circulation. ATP (your cell's energy source) drops so low that follicles enter a dormant, thinning phase.
Kiierr's medical grade lasers recharge that follicle "battery." They stimulate ATP production inside the follicle, restoring the energy it needs to wake back up & grow thicker, healthier hair again.
This is how dormant follicles become active follicles, naturally.
By age 40, men and women lose up to 40% of scalp circulation, starving follicles of oxygen and micronutrients. Add DHT into the mix and hair loss accelerates. Kiierr reverses that.
The laser light increases micro-circulation around each follicle, counteracting DHT damage while delivering the oxygen and nutrients needed to repair, strengthen, and rebuild thicker strands.
This creates the ideal environment for real regrowth without drugs, surgeries or complicated routines.
Backed by Decades of Research & Clinical Studies
Low level laser therapy isn't new, it's been rigorously studied, FDA cleared, and used by top dermatologists & hair restoration clinics for years.
The science is ironclad: clinical trials consistently show it stimulates regrowth, reverses thinning, helps counteract DHT damage, and reactivates dormant follicles.
Kiierr took that proven technology and made it accessible. Since 2018, we've delivered medical grade laser caps to thousands of people who wanted real results without the clinic visits, prescription drugs or side effects.
No drugs. No appointments. No downtime. Just put the cap on for your session while watching TV, relaxing, or scrolling your phone.
The cap does all the work: increasing circulation, boosting ATP, and helping follicles resist DHT damage while reactivating weak follicles with consistent use.
Over time, you'll see fuller, thicker, healthier looking hair without changing your lifestyle.

It’s a worthwhile investment!
I started using my Kiierr cap almost 4 years ago at 63. After the first 6 months or so, I noticed that there was less hair caught by my shower drain strainer than in the past. My temples and the thinning hair on my crown have filled in.
Frank L
My hair is thicker than it’s ever been!
I suffer from hormone-related hair loss. It was devastating to see my hair become thinner & thinner. I have been using Kiierr for 10 months now. At first I was skeptical (was this too good to be true?), but I was astounded when I started seeing growth after 6 weeks!
Denise C
My hair is a lot thicker!
Thicker hair on my crown has been the most noticeable change since starting with Kiierr. Over the last several months, my hair has visibly thickened, especially in areas that were previously thinning.
Mark R
My hair is thicker and fuller!
After contracting COVID, I experienced severe hair loss. I tried the Kiierr Laser Cap and after 5-6 weeks, new hair began growing on my bald spots. By two months, my hair became thicker and fuller. After three and a half months, I was thrilled with the results and highly recommend!
Marsha W
Nothing worked until Kiierr!
After spending 10 years trying other hair growth products, I heard about the success of laser therapy after researching. As you can see, during the 3 year process of using the Kiierr Hat, I could see remarkable results after only 6 months.
James R
The Kiierr Cap really helped!
I've always had thin hair in the crown but 3 months after having Covid, my hair started coming out in handfuls. The Kiierr cap was what helped along with Kiierr’s shampoo, conditioner and biotin.
Karla P
Recommended by my doctor!
I suffered from a mold exposure that caused excessive hair loss, and this treatment was recommended by my doctor. With continued use of the cap, the vascularity of my scalp has improved. The cap has helped significantly in promoting new hair growth.
Jenna P
Reversed my menopause thinning!
Noticeable menopause thinning led me to try Kiierr's hair cap. After using it consistently three times a week for several months, I began to see real results. My hair started growing back. Even my friends & hair stylist noticed the improvement!
Karen N
I love my Kiierr cap!
I use it faithfully and have really seen a difference in my hairline. It was receding on the sides, temples and front, but has definitely stopped and is actually filling in with hair! I would definitely recommend a Kiierr Cap
Lisa L
Kiierr saved my hair!
At 65, my hair started falling and I was nearly bald. I didn’t want a transplant and couldn’t see a doctor during COVID. I tried Kiierr, and it truly helped. Thickened my hair and stopped the loss. I recommend it to everyone facing hair loss.
Jorge V
This cap made me look younger!
After 5 months of using the Kiierr Laser Cap, my hair is fuller, and I feel years younger. I was skeptical at first, but after speaking with their helpful team, I decided to try it. To my surprise, it really works! Plus, their customer service is fantastic. Highly recommend!
Significant hair growth!
I have been using the Kiierr Hair Restoration Cap for the past 18 months. I have received significant hair growth. Attached are my before and after photos showing the hair growth. I highly recommend the Kiierr Cap.
John J
It’s a game-changer for my hair loss
Easy to use cap which I have been using for about 5 years now, every other day. My hair strands have become thicker & have less shedding. I would definitely recommend the Kiierr cap, especially due to the scientific backup.
Vincent R
Highly recommend all Kiierr products!
The laser cap definitely helped regrow hair over the balding spot on the crown of my head and on my thinning/receding front hairline! I also use the Kiierr shampoo, conditioner and vitamins. I highly recommend all Kiierr products!
Dennis F
Amazing for male pattern baldness!
I highly recommend this product to anyone with hair loss. Male pattern baldness started in my 20s with a receding hairline and thinning crown. I have seen awesome results with red light therapy and it was worth every penny.
Seth G.
It really does work!
After using the Kiierr laser cap, I have regrown a large amount of hair. I am so happy with my results and plan to continue use forever! If you are considering Kiierr, I definitely recommend it. It really does work.
Abby A
The Kiierr cap really worked for me!
I purchased the Kiierr cap 4 years ago. I was losing a great amount of hair every time I shampooed. The cap really worked for me. I recently went to my dermatologist and mentioned the cap & he said that “good laser caps really do work!”
Pauline C
Noticeable hair growth with Kiierr!
I was skeptical at first, but after weeks of using the Kiierr Laser Cap, my hair became thicker, and new growth was visible. I’m convinced it works and will keep using it to maintain my results. Thank you, Kiierr!

Laser Cap Questions
Will this product work for me?
Kiierr laser caps are designed to help both men and women experiencing hair thinning or loss caused by common conditions such as androgenetic alopecia (male or female pattern baldness), postpartum hair loss, menopause-related thinning, stress-induced shedding, or general hair weakening with age. The caps use low-level laser therapy (LLLT), a safe, non-invasive technology that stimulates hair follicles, increases blood flow, and supports stronger, thicker hair growth over time. It works best for those who still have active follicles, meaning some existing hair is present. While results vary from person to person, most users who stay consistent with their treatment see visible improvement in hair fullness and scalp health.
When can I expect results?
Everyone’s hair growth cycle is different, but most users notice early improvements within the first few months. During the initial phase, you may experience some light shedding as weak hairs make way for stronger new growth. Visible thickening and regrowth typically begin around the 3-6 month mark, with the most noticeable results appearing between 6-12 months of consistent use. Continued use helps maintain and enhance your results over time.
What model should I choose?
Kiierr offers several laser cap models so you can choose the one that fits your needs and goals.
The 148 Pro model is a great entry-level choice for those just starting their hair growth journey. It is used every other day for 30 mins and fits up to 23.5" in circumference.
The 272 Premier and 272 Elite XL models provide stronger coverage and are ideal for users with moderate thinning or those wanting faster, fuller results. It is used every other day for 30 mins & fits up to 23.5" in circumference for the standard and 24.5" for the XL.
The 272 DualWave combines 2 laser wavelengths for deeper follicle stimulation and added effectiveness. It is used 6 minutes daily & has a softer, more flexible deisgn.
For those looking for maximum coverage and power, the 302 UltraFlex and 312 DualWave are our most advanced options, featuring the highest diode count and full scalp stimulation. These models are used 6 minutes daily & have a softer, more flexible deisgn.
No matter which you choose, all models use medical grade lasers and deliver the same proven therapy. Higher diode counts simply increase scalp coverage & treatment intensity.
What payment options do you have?
We accept all major payment methods through Shopify, including credit and debit cards, PayPal, and Shop Pay.
You can also use your FSA or HSA account for reimbursement.
Do you have a warranty?
Yes, every Kiierr laser cap comes with a full two-year warranty. If you experience any issues during that time, our support team is happy to help with repairs or replacements. Simply email us, and we’ll make sure you’re taken care of quickly and easily.
What if I don't see results?
Consistency is key with low-level laser therapy. Make sure to follow the recommended treatment schedule and continue using your cap regularly for at least 7 months. Because hair growth happens gradually, it can help to take photos every month to track your progress. If you’ve used your cap consistently and haven’t noticed results after the full treatment period, reach out to our support team. You can read our full policy here.

Bobby T.
A great way to regrow hair without ingesting supplements or using gimmick topical solutions. The ease of use is tremendous and convenient as well. I found it best to pick a consistent time of day to wear the cap every other day and stick with it, so you don't need to worry about forgetting a session. For me it is during lunch break when I know I won't be up and running around. The regrowth was visible and my wife started seeing the results long before I did.
Mick D.
I started using my cap in April 2024. I haven’t taken any other supplements,, just use the laser cap. And as you can see in the pics it helps a lot. I wish I would have started YEARS ago.
Lillian J.
I've had a great experience with Kiierr! The package arrived beautifully and shipping was super fast. I started using the laser cap two years ago, 3–4 times a week for 30 minutes, to address thinning in both corners of my hairline. Over time, I've seen significant hair growth and feel so much more confident. Highly recommend!
Vincent R.
Easy to use cap which I have been using for about 5 years now, every other day. My hair strands have become thicker and have less shedding. Would recommend, espcially since the scientifical backup. Kiierr has been quick in responding to my questions, as well as finding suitbable solutions / offers.
Abby A.
With using the kiierr laser cap I have regrown a large amount of hair. I am so happy with my results and plan to continue use forever!
Mark R.
Service with customer support has been amazing. Shipping also was very fast! Over the last several months my hair has noticeably thickened
Austin W.
6 Months Using Kiierr
Works great, would recommend!
Connie K.
I have had my Kiierr Laser Cap for 3 years now & have been very happy with the improvements that have occurred in my hair density. After 8 months of using the cap, the part had narrowed. You can see how filled in it is along the part on top of my head. I am exceedingly pleased! It is worth way more than the price! I will never be without one!
Kent K.
I have been using the Kiierr laser cap for 4 years. Before I started using it I had a really annoying itchy feeling at the crown of my head. Since using Kiierr that itchiness has stopped. In fact when I stopped using it a couple weeks it has returned so I am confident it is from the laser cap. I am sure it has also helped maintain or improve the hair growth on my head as well. Great product.
Pauline C.
I purchased the Kiieer hair growth laser cap 4 years ago and it is still going strong and maintaining the growth it produced. I was losing a great amount of hair every time I shampooed I hope my before and after pictures convince you to try this product. It really worked for me. I now use it twice a week for maintenance. I recently went to my dermatologist and mentioned the cap and he gave it a thumbs up and said that good laser caps do work.
John J.
I have received significant hair growth over the past 18 months using my Kiierr hair restoration cap.
Brad S.
I’ve been using the laser cap for 2 years and I’m thrilled with the results. Not only has it stopped my hair loss, I have actually grown more, which has been a shock to me. This device has been a game changer for me. My hair looks and feels thicker. It’s easy to use and fits seamlessly into my routine. I was skeptical at first, but it’s definitely been worth the investment. Highly recommend to anyone struggling with hair loss!
Karen O.
Noticeable menopause hair thinning brought me to Kiierr's hair cap, after several months of usage 3x a week, I started to notice my hair growing back as did my friends and even hair stylist!
Karen H.
For Christmas 2020, knowing how much my hair loss bothered me, my husband Stan bought me the Kiierr cap. I was diligent about using it as instructed. Within months, my hairdresser noticed the growth of new hair. It grew back thick & healthy.
Ronald P.
After spending over 10 years trying "other hair growth products", I heard about the success of using Laser Hats and chose Kiierr. As you can see, during the 3 year process of using the Kiierr Laser Hat, I could see remarkable results after only 6 months. Now, after approximately 3years, I’m enjoying the full benefits that surface with a full head of hair! My hair stylist complimented me along the way as she noticed the improvement in my hair growth. Furthermore, she stated out of all the clients she has with hair loss, I’m the only client she has with such a noticeable difference! I am thrilled I chose Kiierr!
Stacy J.
I began losing hair after menopause. I was looking for a way to make my hair healthier when I read about the laser cap. I was hesitant about such an expensive purchase, but as you can see from the before and after photos, it made a difference! (The photos are 4 months apart. ) I have been using my cap for 3 1/2 years now.
Martha T.
I've been using my Kiierr MD Laser caps for about 3 years. In 2020 I lost almost all my hair due to Talogen Effluvium. I tried Rogain, pills, and another popular companies laser cap. Nothing. I was stuck in a chronic phase of hair loss. Friends would ask if I was having chemo! Then in 2022 I started using the Kiierr Laser Cap along with the Kiierr supplements and shampoo/conditioner. . . my hair started growing back! Slowly but surely. I still am using my cap and my hair isstill growing. . . slowly but surely! Their customer service is also wonderful!
Frank L.
I’m a 67 year old male in excellent health and I started using my Kiierr cap almost 4 years ago. After the first 6 months or so, I noticed that there was less hair caught by my shower drain strainer than in the past. This has continued to this day. Over time, my temples and the thinning hair on my crown have filled in somewhat. As a result, I don’t wear a cap nearly as often as I used to which is kind of liberating. The purchase of the Kiierr cap was a very worthwhile investment for me.
Karen C.
I had lost a considerable amount of hair in my late 30’s and early 40’s to the point I was so self conscious I kept my hair super short. I heard about red light therapy helmets from a hair specialist and started my research. I found Kiierr was more affordable and offered natural supplements and hair care products which was in my line of preference. After about six months I started noticing a big difference. I now have been growing my hair out and feel exceptionally more confident in how I look, thanks to Kiierr!
Danita T.
I have been very pleased with my Kierr Cap, my hair was thinning on top from hormone medication. I started using my cap and my has thickened and grown significantly over the last 2 years. Customer service is great, when I had an issue with the cap functioning they sent me the replacement part needed quickly. I have been pleased.
Denise C.
I suffer from hormone related hair loss. It was devastating to see my hair become thinner & thinner. I began researching the laser technology and could not be happier selecting the Kiierr cap. I have been using it for 10 months. At first I was skeptical but I was astounded when I started seeing growth after 6 weeks! Every couple of months, we would take a new picture and the results kept getting better and better. My husband agrees that my hair is thicker than it's ever been. My hairdresser was amazed and plans to recommend it to other clients.
Kevin K.
I have been using the Kiierr 272 Premium Laser Hat since Oct 2020. I have seen significant hair growth. Others have noticed too, some people even think I've had a hair transplant! I'll definitely keep using the cap and would recommend to others. It is pretty easy every other day while watching TV in the evening!
Faye S.
I received the Kiierr laser cap as a birthday gift in June 2021 when I was 84 years old, and have continued using it ever since. As you can see in my pictures, there was good growth after roughly 1. 5 years, and even more now, almost 4 years later. I have been really pleased with the regrowth, though I do still have very fine hair.
Elvira W.
I have been using the laser cap for over 2 years now and have noticed significant improvements in my hair growth. My hair is fuller and thicker, with increased growth at the hairline. I’ve gone through a major life transition in the past few years and the helmet has saved my hair! As a woman in her early 40’s who had long and luscious hair all her life, it was difficult to watch the change in my hair so I knew I had to do something. The Kiierr helmet was just the device I needed! If you’re thinking about it, do not hesitate as it is a great device which is easy to use, and will bring back your hair along with your confidence! I highly recommend it!
Penny T.
I have been using the Kiierr Cap for 15 months and have seen a noticeable improvement in the fullness on the crown of my head. There are many new hairs consistently growing in and it has made a huge difference in my self esteem.
Clayton B.
At 19 my hair began thinning. By 32 I'd lost most of the hair along the hairline. I first tried Rogaine that offered some improvement, but later stopped it and began using Kiierr. My hairline has dramatically improved. I feel the hat has been essential in improving the overall thickness and health of my hair and have been a regular user since 2021! I intend to use the laser hat for the rest of my life and expect it will continue to improve my hair and stop my hair loss!
James R.
Ive been using the laser cap for 5 months and it has made a huge difference. The large spot that my scalp was showing is really filling in now. I feel like I look years younger. I was hesitant to purchase cause it seemed like it was too good to be true. But I took a chance on it and to my surprise it definitely did work! Awesome company and awesome product. Im now a believer in laser therapy.
J. H.
My hair feels thicker, healthier and I’m not seeing as much scalp near my part.
Rochelle A.
I have been using Kiierr hair growth cap for a few years now consistently. I started getting bald areas along the crown and my hair line. Not sure what was causing it. But after some research I learned that red light therapy was good for follicle stimulation. And in a few weeks I started to see some small growth. So I continued for months and it definitely started to fill in. My part and hair line are no longer see-through and thinned out. I still use the cap every other day- I feel it really helps keep my scalp / hair follicles healthy.
Steve J.
I have been using the Kiierr 272 Premium Laser Hat since Oct 2024. I have already seen tremendous hair growth. I feel the Kiierr hat definitely helps with better blood circulation contributing to hair growth. Worth giving it a try and backed by their guarantee.
Samantha G.
After giving birth I experienced a lot of postpartum hair shedding, which was really hard to deal with. It started to take a huge toll on my confidence. That's when I discovered the Kiierr laser cap. I was honestly amazed at how quickly I began to see results. After just a few months I noticed less shedding & even some regrowth in the areas that had thinned out the most. My hair feels fuller, and I can see a visible difference in its thickness. Getting my hair back has been such a huge confidence booster.
Hess S.
I love my Kiierr cap. It gave me my life back! I also love Kiierr’s customer service.
Jeffrey L.
I've been extremely impressed and pleased with my results from using the cap. My hair was thinning on the front and top of my head but has since noticeably filled in from consistently using the cap.
Samin E.
I was skeptical at first but I looked up university studies through PubMed & saw there was a direct relationship between alopecia, and laser therapy so I made the purchase. I first went through a mild shedding phase after the first month. At months 2-6 is when I noticed a significant difference. I’ve since halted my hair loss completely and am very pleased with the Kiierr brand & appreciate that they’re based here in US

I’ve been using Kiierr for over a month now and have seen a noticeable improvement. My hair feels thicker, healthier and I’m not seeing as much scalp near my part. It definitely feels stronger and I seem to have less breakage.
