How does the idea of regrowing your hair with a simple brush sound to you? No matter how crazy this may sound, it’s now possible, thanks to low-level laser therapy (LLLT). Today LLLT devices exist to help your hair grow faster, thicker, denser, and healthier. While most systems are designed in the form of helmets and caps, some can also be found as combs — which are more affordable. So if you are looking for the best laser combs for hair growth you are in the right place. Keep reading this post as we answer all the questions surrounding laser treatment, how it exactly helps hair growth, and the best products you can use at home.

First, laser devices are meant to help people suffering from hair loss. But they can also help prevent breakage and thinning hair, which is why they are useful for anyone looking to improve hair appearance, and not necessarily to make it grow faster. According to a 2019 study, laser combs are an effective treatment for androgenic alopecia and other forms of thinning hair in men and women with minimal adverse effects.

Did we get your attention? Good, as there’s more to find out about these laser combs for hair growth!


What is a laser comb? 

A laser comb is a handy and easy-to-use device that works with low-level lasers to penetrate the scalp layers and heat the hair follicles, which helps stimulate hair growth. The light triggers biochemical changes within body cells, and the effect is similar to the process of photosynthesis in plants. 

How laser combs promote hair growth?

The combs generate light from low-power lasers that, when absorbed by the hair follicles, enhance cell metabolism rate, and improve scalp blood circulation, allowing follicles to receive more oxygen and nutrients. Studies confirmed that laser irradiation might cause an increase in blood flow volume in the scalp, thanks to which hair becomes healthier while grows quicker and thicker. 

Research also found that LLLT may prolong the growing phase’s duration and prevent hair follicles’ premature aging. Yes, these lights actually heat up your scalp to the point where it reactivates the inactive follicles encouraging them to grow new healthy hair. And it’s all pain-free!

Does laser comb really work?

John L. Satino tested the effectiveness of LLLT using a HairMax Laser Comb. He chose 28 men and 7 women with androgenetic alopecia to take part in the test. After six months of regular treatment, a new 55% hair count was observed in women, respectively, 74% new hair count in men.

With a different approach, Zarei M., along with four teammates, has searched through PubMed, Google Scholar, Medline, Embase, and other databases to find comparative studies regarding LLLT and hair growth. “We found that the LLLT devices are both safe and effective in treating pattern hair loss especially for those who did not respond or were not tolerant to standard treatments.” In other words, if nothing worked for you yet, then there is more likely that a laser comb will make difference. 


However, if your hair follicles are too damaged, don’t expect miraculous results. “If you’ve got a shiny bald head, a laser comb for hair growth won’t do anything,” says Michael Hamblin, associate professor of dermatology at Harvard Medical School, for WSJ.

The best laser combs for hair loss of 2021

Perhaps you want to reduce hair loss, or you aim for denser hair, so we bet that one of these best laser brushes for hair growth can help you a lot.

HairMax Ultima 12 Laser Comb for Hair Growth

HairMax Ultima 12 Laser Comb

HairMax is the pioneer of at-home laser hair regrowth treatments and is the undisputed global leader in the field, bringing doctors-recommended devices in the comfort of your home.

HairMax Laser Comb does not use LEDs but 12 medical-grade lasers that need eight minutes per day to make your hair appear thicker. It’s definitely the best laser comb for hair growth out there. Besides, the device is FDA cleared for home use and is clinically proven to encourage hair growth and reverse the thinning process. Also, it includes a hair parting teeth mechanism to help deliver maximum light energy to your follicles. Without teeth, hair can block laser light from reaching the follicles. More good news: the laser diodes are closely placed within the devices to provide consistent and uniform light delivery.

It’s practical, cordless, and comfortable to use everywhere, with a lightweight design. Like the previous device, it features exclusive hair parting teeth incorporated, making it more efficient in reaching your scalp for maximum benefits. It’s enough to use the comb for 11 minutes daily until you get the hair you want. Then, you can still use it every other day to maintain your hair healthy and strong.

Glemme Laser Hair Growth Brush

Best Laser Hair Growth Brush

Another best laser hair growth comb comes from Glemme, which promises to bring you transformative results with no less than a 39% increase in hair density after 20 weeks. What’s special about this one compared to other devices is that it has a small tank where you can add minoxidil to increase treatment effectiveness. Once this brush touches your scalp, it’ll feed your hair follicles not only with lasers energy but minoxidil too. And don’t worry as minoxidil actually works well with laser devices and together they are more likely to get you fuller hair.


3-IN-1 Phototherapy Laser Comb for Hair Growth

3-IN-1 Phototherapy Scalp Massager Comb

You get three types of therapies in one device — yes, that’s true! This is possible with Yeamon comb that uses high-frequency, red light, and blue light to make your hair just perfect. Hair loss, greasy hair, and knots will no longer be a problem with this comb. The high-frequency silent vibration helps muscles relax and stimulate cell activity, strengthening your hair, while the soft infrared light boosts blood circulation so that more nutrients and oxygen can be sent to hair follicles. At the same time, the blue light relaxes the scalp muscles, having anti-inflammatory effects while regulating sebum production. Definitely a win-win!

NutraStim Professional Hair Growth Laser Comb

NutraStim Laser Comb

NutraStim made a simple and safe (FDA-cleared) device that uses 12 cutting-edge low-level lasers to stimulate hair growth from the roots. Brush your hair three times a week for 8 minutes with this comb, and you’ll see how your hair will grow ticker — BTW, using it more often won’t accelerate the process, just be patient. It’s important to have your scalp clean before treatment to prevent oil build-up or blockage in the pores so hair follicles will absorb the light. Finally, you should know that the device is not suitable for severe or mild hair loss, but moderate mostly and it’s great for those who want to prevent it.
