Around 7 million in the US and 160 million globally have experienced alopecia areata (a kind of hair loss). This dire number is the reason the demand for hair growth devices has exploded in the last few years.
However, with so many options in the market, choosing the right one can be overwhelming. So, this guide will help you make a choice.
How do Laser Hair Growth Devices Work?
Laser hair growth devices use low-level laser therapy (LLLT) or red light therapy (RLT) and deliver effective wavelengths of light to the scalp that promote hair growth.
The light, when absorbed by the scalp, stimulates cellular activity within hair follicles. This energizes dormant follicles into the growth phase and may even reduce hair shedding.
Familiarizing with Types of Laser Hair Growth Devices
The common types of laser hair growth devices are:
Laser Caps and Helmets
Laser caps and helmets are the most advanced type of hair growth devices on the market. They have tens to hundreds of laser diodes, distributing red light of appropriate wavelength across the scalp to promote hair growth.
Specific laser cap and helmet models use both laser and LED technology to enhance scalp coverage and the ability to penetrate into the deeper layers of the scalp.

You generally have to wear these helmets for up to 12-30 minutes for each session. The exact timeframe varies depending on the product design and power.
Pros
- Full scalp coverage
- Hands-free application
- Consistent application for every session
- Most effective of all devices
Cons
- High upfront expense
- The device may feel bulky for some
Laser Bands and Combs
Laser bands and combs are handheld products that function the same way as caps and helmets. You don’t have to wear them and instead need to run them across your scalp manually during treatment.
Pros
- Much more affordable than caps and helmets
- Portable and compact, so no chance of missing sessions if you travel frequently
Cons
- Needs manual effort in repositioning for full scalp coverage
- A treatment session is usually longer
LED Therapy Hats
These devices have only an LED red light and no lasers. Similar to baseball caps, these are ideal for discreet use. LED lights are less concentrated than medical-grade lasers. But they function within the commonly used wavelengths of photobiomodulation therapy.
Pros
- Can be used discreetly
- Can be worn during daily activities
Cons
- Not as effective as laser devices
Key Features to Look for Before Buying
Next, you must focus on the following to choose the right device.
FDA Clearance
When choosing a laser hair growth device, pay attention to its safety standards. Some devices on the market have received regulatory clearance for treating pattern hair loss in both men and women.
FDA clearance never promises success rates, but it at least gives you peace of mind regarding product safety and performance standards.
Number of Laser Diodes
In the market, you will find a range of laser hair regrowth devices. Some have hundreds of lasers and LEDs to deliver even light treatment for the entire scalp. On the other hand, the smaller devices have a minimal number of lasers and LED light sources.
You should choose a device with maximum diodes to ensure wide scalp coverage and short treatment time, ensuring more consistent therapy. In addition, you must also consider the device design and power output while evaluating the device.
Treatment Duration
The next thing to consider is the length of the session. With high-quality devices of appropriate power, you can be done with daily sessions of around 10-15 minutes. On the other hand, when using devices of lower power, you may need around 30 minutes of sessions more than once a day every week.
Comfort and Usability
Hair restoration treatments take months to years to offer lasting results. So, comfort is the next important factor. The more comfortable you feel with the device, the more likely you are to stick to regular schedules.
You must look for a device that has an adjustable fit, good ventilation and airflow, a lightweight build, and hands-free function for the best experience.
Warranty and Return Policies
Hair regrowth takes time. The slow process needs you to use your device for at least 6-12 months consistently, and only then will you notice obvious results.
For this reason, you must look for a product with a satisfaction guarantee, a reasonable return window, and a multi-year warranty. These policies minimize the financial risk of trying a device for the first time.
Conclusion
Now that you’re aware of the common laser hair growth devices and the most important features to prioritize, start researching your options. Invest in one that is aimed at your specific hair loss condition.
