While various devices are available that promise new hair growth, one that seems to be gaining popularity is the new laser cap by Kiierr, which harnesses the power of low-level laser therapy (LLLT) to potentially stimulate hair growth and restore what’s been lost.
Looking to buy this acclaimed, non-invasive hair growth system but unsure if it really works is it is worth the money?
In this Kiierr Laser Cap review, we will look into the science behind LLLT, explore the cap’s features, pros, and cons, what sets it apart from similar hair growth devices on the market, and provide an in-depth review to help you decide if it’s right choice.
but first, let’s explore LLLT’s use for hair growth.

What is Low-Level Laser Therapy for hair?
Low-level laser therapy (LLLT), aka red light therapy or cold laser therapy, is a non-invasive treatment for hair loss.
It involves a low-powered, specific-wavelength laser that the hair follicle absorbs.
This gentle stimulation helps improve blood circulation to the scalp, reduce inflammation, and encourage dormant hair follicles to re-enter the growth phase.
It’s similar to a sunburn. Sometimes, you don’t even feel the light on your skin.
Low-level lasers are generally safe and FDA-cleared to treat a range of medical conditions. Also, synergizes well with other products, with a few mild side effects. They’re especially effective in treating androgenetic alopecia and are often used alone as a complementary treatment to minoxidil and finasteride.
While the laser is so low-powered that it has little effect on the hair itself, it can influence the body’s response to hair growth and induce hair to grow naturally in thinning areas.
Laser hair growth caps are one way of receiving LLLT for hair growth, and a safer, less invasive alternative to hair transplant surgery.
Laser hair growth caps, like Kiierr’s hair device, can help you deliver LLLT therapy without leaving your house.
The science behind
- Step 1 (light penetrates): Medical-grade laser diodes within the Kiierr laser cap system emit specific wavelengths of light (typically around 650nm) that safely penetrate the scalp tissue.
- Step 2 (cells activate): By absorbing this light energy, the hair follicles stimulate cellular activity.
- Step 3 (blood flow increases): The stimulated follicles trigger extra blood circulation to the scalp which delivers essential nutrients and oxygen.
- Step 4 (inflammation reduces): LLLT’s anti-inflammatory effects help create a healthier environment for hair growth, as inflammation is often linked to hair loss.
- Step 5: A combination of increased circulation, nutrient delivery, and reduced inflammation induces dormant hair follicles to move from the resting (telogen) to the growing (anagen) phase. Ultimately, this leads to new, thicker, and stronger hair growth.
This treatment can take at least seven months, but you’ll start noticing reduced hair shedding after 6-8 weeks. Usually, it takes four to eight weeks for the laser cap to start working.
About the brand
Kiierr is a pioneer in the development and application of hair growth lasers.
Founded by Mike and Jolene Anderson in 2018, Kiierr is a husband-and-wife team. Due to Mike’s personal experience with losing his hair, the couple was driven to heal others through low-level light therapy (LLLT). As someone who has been helped by the therapy, they decided to share their story with other people. That’s why they founded Kiierr International since they truly care about their customers.
The laser cap aims to restore hair growth by targeting hair loss-causing follicles in the scalp.
A number of experts recommend the Kiierr hair cap as an option for treating hair loss, and FDA approves it. With this device, people suffering from hair loss issues have been able to increase their hair count and grow a full head of hair.
A non-invasive, painless therapy, Kiierr works remarkably fast, delivering significant results as quickly as possible.
Most patients undergoing treatment for hair loss and baldness have given positive feedback: they highly recommend the Kiierr laser cap. However, its effectiveness before and after use is controversial, and many are skeptical. Even so, the effectiveness is scientifically proven.
Kiierr Laser Cap Models
The brand offers three models:
- 148 Pro: ideal for mild hair loss or early stages
- 272 Premier: more powerful, suited for moderate to severe hair loss
- 302 MD Ultra Flex: the most advanced with more laser strength and maximum scalp coverage
All the models are similar, boasting a similar design, advanced laser technology, convenient features, flexibility, and operating modes.
Compared to the Kiierr148Pro Laser Cap, which contains 148 laser diodes, the Kiierr 272 Premier laser cap has as many as 272 laser diodes. And 302 MD Ultra Flex features 302 diodes. As a result, the Kiierr148Pro offers narrower coverage than the Kiierr272Premier and MD Ultra Flex. Because of fewer lasers than its counterpart, Kiierr148Pro is more suitable for treating mild alopecia, new hair loss, or minor hair loss.
With many lasers, the Kiierr272 Premier and MD Ultra Flex provide a greater coverage area for more severe hair loss and baldness cases. Moreover, the stronger output of these models also provides a faster treatment effect.
The Kiierr272Premier costs nearly twice as much as the Kiierr148Pro Laser Cap. The KIIERR148Pro is a bargain for people who wish to receive laser treatment in the comfort of their own homes. However, it does not cover enough hair to treat baldness.
To treat severe hair loss, we recommend the Kiierr272Premier or 302 MD Ultra Flex with Complete System, which includes a hair vitamin, shampoo, and conditioner that help speed up the treatment process.
How to Use the Device?
Before using the treatment, you must have a clean and healthy scalp.
Step 1: Unbox and connect the charger to the power pack. Use only the portable power pack included in the kit and never directly into an outlet. Charge it completely in advance.
Step 2: Place the cap module into the ball cap. Fit the Kiierr Laser Hair module into the black ball cap provided or any standard ball cap of your choice.
Step 3. Connect the USB power adapter and the laser hair cap module. Make sure the USB cable is fully plugged into the cap. Do not attempt to connect the USB by force as it may be upside down.
Step 4: Switch on the cap once you’ve placed it on your head. When it is on, the device will blink and then turn itself off after 30 minutes. Do not look directly at the lasers.
Depending on the severity of your hair loss, you should use this cap every day for a minimum of six months.

Here’s our review of this device so you can get a better feel of it.
Review of Kiierr Laser Cap
Plain black, the cap is easy to wear because it looks like a regular baseball cap. Lightweight and measuring 23.5 inches in circumference, it fits most heads.
Unlike most caps, it contains no plastic, which is a real plus. The body is fully metal and quite sturdy. The cap has a small rubber cushion to protect it when not in use, and its design makes it easy to wear and take off.
The wall charger comes with a USB cord, so you can connect either the USB cable or the power outlet. You only need to charge the portable power pack that’s attached to the laser cap, not the cap itself.
Four light indicators indicate how much charge is left in the power pack. As soon as the power pack is fully charged, you connect it to the laser cap itself, so you can use the device without being tethered to a wall outlet. With a portable power pack, you can move around while using the cap, just like with a power bank. While the portable power pack allows mobility during treatment, it’s recommended to remain still for optimal results.
About 300-350°F is the ideal temperature for this cap. The Kiierr laser cap for hair growth distributes heat evenly throughout the hair shaft. Moreover, it is non-invasive and painless, so there is no burning.
With the automatic shut-off timer built in, the cap automatically shuts down after 30 minutes.
When you use the cap for the first time, you will lose more hair than usual. If this happens, you shouldn’t stop using it immediately since it’s quite normal—the laser light will quickly remove the hair that falls out to make way for new hair.
Wear the cap for 30 minutes every other day doing your thing, and you’ll begin to notice some improvement within a few weeks. It’s best to consistently try the treatment for at least seven months before expecting huge results.
You can use it alone or combined with other treatments such as Minoxidil, hair serums, and hair growth supplements.
There is a 93% success rate for this hair device in clinical studies, proving that it works both for men and women.
If you have any issues with the device, you can contact Kiierr right away. The website offers a chatbox and a hotline, so it’s super convenient. Also, Kiierr’s laser hats come with a 2-year manufacturer warranty.

How long does it take to work?
Using laser caps may not give immediate results overnight or even after a few days. Taking care of your hair from the inside out takes time, so it won’t happen immediately.
While not all clients find the same level of success with their cap treatments, the average is about 6 to 10 months.
It may take longer to get the same results when you have damaged hair, redness, white spots, or thin hair.
Treatment with Kiierr’s cap should last between four and twelve months, every other day. After that period, you can maintain the hair’s quality by continuing sessions once or twice a week.
We have found that the Kiierr Laser Cap price is affordable, and it is an excellent device for people with hair growth cycles that are too quick.
As a result, it is ideal for keeping unwanted hairs from growing or improving hair regrowth.
Is it safe? What about the side effects?
Kiierr uses a low-level laser light, 560nm, that is not harmful to the skin and scalp.
No side effects have been reported at this point, but lasers around the eye should be used with caution. Don’t turn the cap on until you wear it.
