When struggling with hair fall or thinning, you might often find yourself researching solutions that can help you regrow hair.
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 uses 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, or if it’s 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 feels similar to a sunburn. Sometimes, you don’t even feel the light on your skin.
Low-level lasers are generally safe and FDA-cleared for treating a range of medical conditions. Also, synergizes well with other products, with a fewer side effects. They’re especially effective in treating androgenetic alopecia and are often used alone or 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 influences 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 in the Kiierr system emit light at a 650nm wavelength to safely reach the scalp tissue.
- Step 2 (Cells activate): Hair follicles absorb this light energy to trigger cellular activity.
- Step 3 (Blood flow increases): This stimulation creates better circulation to deliver essential nutrients and oxygen to your roots.
- Step 4 (Inflammation reduction): The anti-inflammatory effects help create a healthier environment for growth, as inflammation is often linked to hair loss.
- Step 5 (Follicle transition): 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.
You’ll typically notice reduced shedding after six to eight weeks. Significant results usually take at least seven months of consistent use.
About the brand
Kiierr is a leader 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). After seeing success with low-level light therapy himself, the couple decided to share this solution with others. So, they founded Kiierr International,
The Kiierr laser cap aims to restore hair growth by targeting hair loss-causing follicles in the scalp. Their personal connection to the product means they truly care about their customers and the results they achieve.
Many experts recommend the Kiierr hair cap as an option for treating hair loss, and the FDA approves it.
A non-invasive, painless therapy, Kiierr works quite fast, delivering significant results as quickly as possible.
Most patients undergoing treatment for hair loss and baldness have given positive feedback. 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 different models based on your level of thinning. While all share a similar design and technology, the number of diodes changes the coverage area.
| Feature | Kiierr 148 Pro | Kiierr 272 Premier | Kiierr 302 MD Ultra Flex |
| Ideal for | Mild hair loss | Moderate hair loss | Severe thinning |
| Laser diodes | 148 | 272 | 302 |
| Coverage | A bit narrow | Maximum scalp | Full scalp |
| Price point | Budget-friendly | Mid-range | Premium |
The 148 Pro is suitable for early stages of thinning. However, it does not cover enough area to treat extensive baldness.
For more severe cases, we recommend the 272 Premier or the 302 MD Ultra Flex. These models provide a greater coverage area and a faster treatment effect because of the higher laser count.
Purchasing the complete system, which includes a hair vitamin, shampoo and conditioner will help speed up the treatment process.
What’s included in the Kiierr System?
When you unbox your Kiierr hair growth system, you will find a complete kit designed for ease of use.
- Laser Helmet: This is the core module containing either 148, 272, or 302 medical-grade diodes.
- Plain Black Ball Cap: The module fits perfectly inside this hat, making the treatment discreet.
- Portable Power Pack: This battery allows you to move around your home during your session.
- USB Cord and Wall Charger: You use these to keep your power pack ready for action.
- Stretch Fit Headband: This helps keep the cap secure if you have a smaller head.
- User Manual: A simple guide that explains the FAQ and usage instructions.
The system is designed to be plug-and-play. You do not need any special technical knowledge to get started.
How to Use the Device?
Using the cap is surprisingly simple. Before starting a session, just ensure your scalp is clean and free of any products.
Charge the battery: Connect the power pack to the wall charger. Use only the portable power pack included in the kit and never directly into an outlet. Charge it fully before your first session for a healthy battery life.
Assemble the cap: Fit the laser module into the provided black ball cap or any standard ball cap of your choice. It clicks into place quite easily.
Connect the power: Plug the USB cable from the cap into the portable power pack.
Start the session: Place the cap on your head and switch it on. The device will blink to indicate it is working.
Automatic shut-off: The cap will run for 30 minutes and then turn itself off. This prevents you from over-treating the area and makes the process entirely hands-free.
Aim to use the cap for 30 minutes every other day for a minimum of 6 months. Consistency is the most important factor in seeing results with any LLLT device.
Here’s our review of this device so you can get a better feel of it.
Review of Kiierr Laser Cap
The cap is easy to wear because it looks like a regular baseball cap. It’s lightweight and fits most heads comfortably.
The body of the module is made of sturdy metal which feels much more durable than the plastic helmets offered by some competitors.
The cap has a small rubber cushion to protect it when not in use, and the 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’s 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.
