Best Red Light Therapy for Hair Growth

It was a matter of time before lasers beamed their way for hair growth to swerve. So today, we will shine the spot or shed light on red light therapy for hair restoration.

We all know about hair loss. It can happen for various reasons like age, genetics, medical conditions, diet, stress, etc. Thankfully, this new method may prevent, treat, or slow it down.

You are probably puzzled with questions about this innovation and don’t worry cause we will help you understand how red light therapy works and what it does for regrowing hair.

Red light therapy may repair muscle, cell, and skin tissue damage and promote regeneration and strength using near-infrared light, infrared therapy, or another type.

This treatment is revolutionary because it exposes the parts of your body to low levels of infrared light, which may help the damaged hair follicles and promote new hair growth.

Therefore, we will list the best red light therapy for hair growth products that customers who are struggling with hair loss swear by.

Red Light Therapy For Hair Growth


How We Made This List

Before we start with the product reviews, we will talk about how we picked the products and which features we looked for.

These were some of the most critical factors:

Device design 

These devices come in two options: caps and helmets. In our opinion, the caps are a more discreet option than the laser hair growth devices since they look like regular baseball caps.

We thought many individuals would prefer this option since they can be worn everywhere without drawing attention. 

They can be set to work between 6 to 30 minutes and can be used daily or weekly. These are convenient to wear while you run your errands or do your work. 

We’ve also included helmet types of devices. Even though they are a bit bulkier and more noticeable than caps, they would benefit individuals with severe hair loss since they tend to have more substantial power. 


The FDA approval was an absolute must while we picked the products. We checked whether they were rigorously tested for safety and met specific quality control and operational standards.

We strongly avoided devices that weren’t FDA-approved since they imposed a great possibility of malfunctioning or overheating and causing great harm to users. 

Device size 

We decided to include products that fit the standard capsize so that they would suit the majority of users.

These products are painfully tight and uncomfortable to wear in most cases, so we ensured they might be adjusted to accommodate unusual head sizes and shapes. 

Hair loss extent 

Helmets and cap types of red light therapy devices are excellent options for everyone who wants to treat the whole head. Therefore, we looked for those devices that can cover the top of the head and the sides. 

Cycle time 

Usually, these devices are programmed to work for 20-30-minute sessions two to three times a week or shorter sessions of 3-10 minutes a couple of sessions daily.

The products we selected can be adjusted to the program according to your needs if you have a busy schedule.

Also, we have included those options that have longer sessions for anyone looking for more intense treatment. 


We understand that many people would like the idea of carrying these devices when they are traveling for work or a holiday and can easily store them in their bags.

The products on our list are best for at-home use; however, some of the options can be easily carried in your luggage.

Price range 

This wasn’t the most crucial factor we looked for because we gave more advantage to the quality. However, the top-priced options aren’t necessarily the best, so we chose some affordable options.

Factors to Consider When Buying RLT for Hair Growth

Type of the laser device

As you can see, there are many types of laser devices – helmets, caps, combs, and bands, and they work differently.

Laser helmets

Laser helmets are mostly recommended for individuals who experience baldness in the scalp area and crown region.

They are effectively targeting the receding hairline, which is mainly concerned. The number of laser diodes working on these products usually varies between 50 and 120.

Lase caps 

Lase caps are mostly recommended for people that are balding all over their head, including the back of the scalp.

In most cases, these products are more effective and, with that in mind, more expensive since they have an increased number of working laser diodes.

Laser bands

Laser bands are used as any other band, except they treat the parts of the head where the hair falls the most and help it grow back.

They are mostly recommended for everyone that struggles with receding hairline issues. They are also useful for concentrating the laser direction on any particular patch. 

Laser combs

Laser combs offer more control over the laser. If you have an irregular heart count or bald patches, these products would be the most suitable option.

They might concentrate the laser on a particular spot and give you the freedom to light other scalp regions. However, if you are a beginner to these devices, laser combs aren’t recommended much since you might go overboard with them.

Laser wavelength 

The wavelength of the laser mainly determines the efficacy of the product. It’s measured in nanometers.

It’s recommended chiefly to choose red light helmets and capes with a wavelength between 630nm to 650nm

Our recommendation is to stick to the lowest wavelength since going above might be harmful to you. 

Number of laser diodes 

When choosing the best red light therapy for hair growth, you should stick to the products with a minimum laser diode of 50. However, more is always better.

This means that the laser diodes may have better coverage, and the light might be more evenly distributed and get more abundantly soaked in the hair follicles. 

It’s always good to look for uniformity in distribution and read the product instructions first to understand better how it works. 

Usage duration

If you think that you are starting to lose hair because of stress, then it’s most likely that you aren’t looking for a device that you can wear for a more extended period of time and use daily. 

This is why it’s good to look for a device that doesn’t demand too much of your time or you can wear it discreetly.

In this case, caps are appropriate for you. However, if you still want to choose a helmet type of product, pick those that don’t demand spending more than half an hour wearing them.

Frequently Asked Questions 

How does red light laser therapy work?

Red light laser therapy devices work by stimulating the cellular activity in your follicles by slowing down and minimizing hair loss while supporting hair regrowth. 

They are safe and effective and a straightforward method that you can use in your own home. Some of the most important benefits may be: 

  • Stimulating hair regrowth
  • Increasing hair density
  • Reducing further hair loss
  • Improving the condition of the hair

How long will it take to see the results from red light therapy devices?

It is said that the devices that have extra lasers provide a more comprehensive scalp coverage, which automatically means that they might produce effects faster.

However, this isn’t proven since several other conditions determine how much it will take to see the effects.

It’s believed that with regular use of hair loss, red light treatments might have the ability to increase hair density and reduce hair loss within 12 to 24 weeks.

Studies show that the first visible results are usually reported after eight weeks but are still also different from one individual to another. 

Can red light therapy devices be used with other hair loss products?

Yes, in most cases, these devices are strictly recommended to be used in combination with other remedies and treatments.

Experts report using biotin serums to maximize the effectiveness of these devices. Still, you should read the instructions first and see whether there are any other types of productions that the brand recommends. Also, it’s recommended for them to be used alongside finasteride or minoxidil.

Some studies claim that red light therapy devices have no adverse effects when used and are FDA-approved medications in both male and female cases of androgenetic alopecia. 

However, we recommend using red light therapy first and then applying the topical treatments afterward to prevent the risk of burning or irritating your scalp.

Does using red light therapy for hair growth hurt?

Red light therapy for hair growth doesn’t hurt. You shouldn’t even feel warmth since the lasers used in these devices are low-level and are considered “cold” as they don’t generate heat. 

The entire process is painless and discomfort-free since there is no itching, vibration, or prickling sensation. 

Are there any possible side effects from using red light hair loss treatment?

There shouldn’t be any serious side effects when using these devices. However, if you wear them for a prolonged period of time, they might put some pressure on the scalp and pull your hair.

This might increase the presence of scalp bacteria, which may result in itching, dryness, flaking, or scalp irritation. 

Is a prescription required when buying these devices?

No prescription is needed to buy a red light therapy device. However, it’s always wise to talk with a dermatologist first and ask for their advice. 

On the other hand, if you want to use them with minoxidil, you’ll need a doctor’s prescription since it’s an over-the-counter treatment.

Biotin can be bought in every supermarket and is usually available in every pharmacy. 


When you type in the best red light therapy for hair growth in your search engine, you’ll be flooded with many products, and it can be overwhelming to pick which one would be the best for you.

Many types of devices work on different mechanisms, so finding which one is suitable for your condition is especially important if you want to have satisfying results.

So, to make it easier for you, we chose the best red light therapy for hair growth devices available on the market. All of these options are safe and FDA-cleared, so you can rest assured that you won’t face any adverse effects. 

However, before you start the treatment, make sure to choose the most suitable device for your condition. Otherwise, you might not get the expected results.
