What are Laser Hair Growth Devices and How Do They Work?
Laser hair growth devices are non-invasive products designed for men and women who are experiencing hair loss and want to initiate regrowth. Laser therapy for hair is also referred to as cold laser, red light therapy, or photobiomodulation.
These products emit low-level light therapy, dispensing photons deep into the scalp to activate the hemoglobin and improve blood circulation. They also activate the hair follicles, leading to cell regeneration and additional growth.
About Low-Level Laser Therapy for Hair Loss
A Hungarian physicist accidentally discovered that low-level laser therapy was effective for hair loss in 1967. A study where he used laser therapy with mice had the additional effect of growing extra hair.
Despite this, the first laser therapy for hair removal device didn’t come out until 2000, in the form of a laser comb for use at home. In 2007, the first FDA approved laser comb for men hit the market. In 2011, a similar product for women came out (1).
Research has demonstrated the effectiveness of this technology over and over again. For example, a review of studies published in Lasers Medical Science looked at 21 studies and found that the majority of then showed positive results for hair growth.
A very recent review article from September 2020 in Skin Appendage Disorders showed both the efficacy and the safety of low-level laser therapy for hair loss.
How Does Laser Therapy (LLLT) Work?
Laser therapy for hair loss functions through several mechanisms which stimulate hair growth. The laser penetrates into the cells, stimulating the hair follicles and initiating more cell division, as well as reducing any inflammation.
The device also leads to the release of additional nitric oxide, which improves circulation in the scalp and enhances its health. In addition, the laser can inhibit an enzyme called 5-alpha reductase, which causes testosterone to convert into the hormone dihydrotestosterone (DHT). This substance plays a role in hair loss.
The result of laser therapy for hair growth is that the follicles become more active, leading to hair growth. It also lengthens the active growth phase of the hair.
About Laser Caps for Hair Loss and Regrowth
Laser caps are probably the most common laser therapy for hair growth devices. The are in the form of a helmet or cap you wear on your head for a specified length of time (usually 30 minutes) on a regular basis while it delivers low-level light therapy.
They cover almost the entire scalp and deliver up to 272 diodes. This makes them more powerful than bands or combs. Where they may fall short is for people who have very thick hair, as it may block the scalp from the effect of the laser.
What are the Types of Laser Hair Growth Devices?
Laser therapy for hair regrowth devices may be in the form of a cap you wear on your head for a specified amount of time, a hair growth comb, or a laser band.

Things to Consider When Buying the Best Laser Hair Growth Device
Before you choose laser treatment for hair removal at home devices, consider a number of factors. Initially, you have a device which type of device to buy. Someone with severe hair loss is much better off with a cap or helmet, which covers the majority of their hair. A comb is better for someone with minor hair loss. People with very thick hair should not use a helmet or cap if the hair can block the laser.
Also, consider the price, and what your budget allows for. Some of the helmets are quite expensive. In addition to cost, the safety of the product is important. The technology is FDA approved, and the product should be as well. If it’s not, do not purchase it.
You should check the power of the device, in terms of how many diodes it has. The upper limit is 282 diodes. Make sure you get a powerful product. Finally, check if the manufacturer has listed side effects.
Helmets vs Combs
FDA Clearance & Severity
Time and Dedication
Amount of Low-Level Lasers
Helmets cover your entire scalp, making sure the laser reaches every area. You don’t have to touch it once you’ve turned it on, you just sit and wait. They have up to 282 diodes, which is a lot more than most combs would have. One issue is that they are not good for people with thick hair, as the hair prevents the laser from reaching your scalp.
Combs are smaller and less powerful, but they are a good choice for people who have scalp irritation that they want to itch or massage. The downside is you have to operate them manually. They are much cheaper than caps or helmets.
The first FDA clearances for laser therapy for hair regrowth devices for hair loss were issues in 2007. The technology is FDA approved, as will most of the devices for sale on the market. This is one thing you should check for before you make your purchase.
The prices for the caps vary widely, from about $200 to up around $1500. Sometimes the difference is in the number of diodes, so check that carefully before you buy. Combs are much cheaper, from around $30 to $300.
Low-level laser therapy emits a light which delves deep into the scalp and stimulates follicles and cells. The light may be excimer at 308 nanometers, helium-neon at 632.8 nanometers, or fractional erbium glass at 1550 nanometers.
Low-level laser therapy works, but it takes time for it to really begin to make your hair grow. If you want this technology to help you, you have to make sure you use it consistently for as many months as it takes. If you use the device sporadically, it most likely will not bring the results you want.
There are dozens of different laser therapy for hair devices on the market, so research carefully before you choose one. One key factor in selecting a product is the number of lights it has. More lights mean the device will be more effective at growing your hair. Make this a factor to consider when you decide on which device to buy.
Step-by-Step Guide to Using Your New Laser Hair Growth Device
For a helmet, cap, or band, the instructions for use are quite easy. Before you use the device, wash your hair with a medicated shampoo to lessen any irritation. Follow up with a good conditioner which will prevent hair breakage.
Then dry your hair carefully before using the product. In order to get it to work, you just place the cap on your head. You can do other things at home while you’re waiting for the treatment to end. It usually takes about 20-30 minutes and should shut off on its own when it’s done.
A comb is slightly different in that you have to brush it through your hair for the allotted length of time, about 20-30 minutes.
How to Get the Most from Your New Laser Hair Growth Device
There are some things you can do to really get the most out of your product. These include:
- Study the manual carefully and get to know your device.
- Store the product somewhere cool and dry to protect the mechanism.
- Wash, condition, and dry your hair before you begin.
- Start from the edge of your hairline.
- Follow the instructions carefully.
- Don’t use the device for longer than the recommendation.

What Else Can You Do?
There are some natural ways to encourage your hair to grow which you can try along with your laser hair regrowth device. Try some of these:

- Rinse your hair off with cool water instead of warm or hot. This makes the hair follicles stronger, while hot water could damage the hair.
- Consume plenty of omega3 fatty acids, as they nourish the hair and help it grow. Eat a lot of fatty fish, for example.
- Cut down on or quit smoking if this is your habit. It can decrease circulation in your scalp, making hair growth more difficult.
- Don’t shampoo every single day unless you really have to. Shampooing too much can remove a lot of the natural oils in your hair, making it less healthy.
If you have experienced hair loss, consider purchasing a laser therapy for hair device for home use. Using this type of product on a consistent basis will help your hair grow, and it should come in thicker and healthier than previously. Numerous studies have confirmed the efficacy of this technology.
These laser therapy for hair growth devices are also incredibly easy to use. You place the cap, helmet, or band on your head and go about your business for about 30 minutes while it does its magic. With a comb, you spend about 20 minutes brushing through your hair. We’ve presented a number of good models in this article which can help you to find a product for you.
