Best Laser Hair Growth Devices 

What is Laser Therapy?

Laser therapy or Red light therapy is a modern technology that transmits photons to the scalp tissue. These photons are absorbed by weak cells to promote hair growth. 

Hair growth laser devices produce red light between 630 to 670 nanometers. It penetrates a few millimeters into the skin and triggers follicles to grow hair if they are in the telogen stage and reactivate it.

This type of therapy has been clinically proven to be effective against hair loss. [1]

The devices available on the market emit infrared or red light on the scalp to improve blood circulation to accelerate hair growth.

A 2016 study found that the FDA cleared Low-level laser therapy (LLLT) devices are appeared to be safe and effective in male pattern hair loss (MPHL) or female pattern hair loss (FPHL).

According to a reliable source from a study, low-level laser therapy is safe and effective for hair growth in both men and women.

Another study examined 41 men aged 18 to 48 found that laser hair treatment increased hair growth by 39% over 16 weeks.

study suggests that low-level laser therapy appeared effective in males with androgenetic alopecia. Other studies also show that LLT is safe and effective for hair growth in both males and females.

Based on these research studies, yes, laser therapy can regrow your hair, but the results are inconsistent and may not work for all.

What is the best laser cap for hair growth?

Different laser hair growth devices are available on the market, and all use medical-grade lasers. Some of the best laser hair growth devices are the iRestore laser hair growth system, Capillus hair growth cap, and Theradome PRO LH80.

They all work on the exact mechanism as they all use lasers, but we recommend you always choose a device approved by the FDA and always check the laser’s wavelength used in the machine. A wavelength between 600-700nm range is considered safe and effective.

Are laser therapy devices safe to use?

FDA will never approve a device if it is not safe for your health. A 2016 study found that the FDA cleared Low-level laser therapy (LLLT) devices are appeared to be safe and effective in male pattern hair loss (MPHL) or female pattern hair loss (FPHL). Please avoid direct contact with your eyes as it may affect your eyes.

What to consider when choosing the best laser hair growth device?

Before purchasing a laser device, you need to know what makes an exceptional device. You will need to be ready for the lengthy process. It takes time to work on the hair, and the results may vary between people depending on certain factors. Here are some crucial points you need to check before purchasing a laser device. 

Is It FDA Cleared?

When the FDA clears a device, it means that it is safe to use. The Food and Drug Administration would not falsely approve a device. They determined that these laser devices would not burn the skin and are generally safe. 

How many low-level lasers are used?

The more layers you have, the more benefits you will see. More lights provide better coverage of the scalp. If you are using the comb, you will not need as many lights because you are moving it. The lights will hit all parts of the scalp. So always purchase a device that has more lasers. 

What is the severity and type of hair loss?

If your affected area is less, you can choose a comb or less laser device, but you need to buy more lasers if your hair loss is more. The amount of hair loss you have will practically dictate the device. A helmet or cap can cover an entirely bald head, and hair loss around the crown or thinning on your part can benefit from a headband. 

Are They Safe To Use—Side effects?

The FDA also monitors the device’s side effects. If the device burned the skin, they wouldn’t approve it. It is essential to know the machine. Some people may claim that their skin has blackened or burned, and it isn’t very likely since the FDA controls laser devices. Generally, this type of therapy is safe with no serious adverse effects.

Always check the device’s nanometers.

When shopping for laser helmets or caps, ensure that the legitimate devices match the average nanometer reading. It must be between 630 nm and 670 nm, and it is the standard quantity for low-level laser therapy devices. 

How much time does it take to show the results?

The way you will see the results is to use them frequently. You should be ready to spend time wearing the helmet, caps, etc. It may take 25 to 30 minutes a day for months to see improvement.

Verdict—Best Laser Hair Growth Device

All of the above-discussed Laser caps have proven effective and are the best laser hair growth devices for regrowing hair. They are safe to use and can be used in the comfort of your home. Since many laser hair loss devices have a satisfaction guarantee, you risk a little more than a few minutes a day to try one.

Kiierr is our top pick because of its affordable price, auto shutoff technology, and 7-months money-back guarantee. Capillus hair growth cap is also a great company committed to your success, and it has also been featured in numerous magazines and newsletters. The iRestore is another best hair growth device because it is one of the hot-selling brands with 1300+ positive customer reviews, and it also has some pretty nifty features.
