Devices like a red light showerhead or a red light hat can range from $450 to nearly $3,000, though, so you want to make sure you pick the one that will be a good investment for your needs. We put three of the most talked-about devices to the test, checking to see which ones are worth a professional’s time and money, and will fit into your daily wellness routine.

Heads Up

Hair loss treatment is a slow, gradual process, and results rarely happen overnight. Most clinically backed options need consistent daily use for several months before meaningful changes become visible. Our own testing is still in the early stages, so any observations so far are preliminary. As more time passes and we collect longer-term data, updated insights and results will be shared here.

Best Overall Red Light Therapy Product for Hair Growth: HigherDOSE Red Light Therapy Hat

Our Thoughts on HigherDOSE Red Light Therapy Hat

The HigherDOSE Red Light Therapy Hat is our pick for the best overall red light therapy product for hair growth because it comes cleverly disguised in a baseball cap. This way, you can wear it during a workout or while you WFH. This hat doesn’t look like a medical device, so no one will know. This red light therapy hat has a built-in automatic timer, too, so there’s nothing to track or remember while using it. It’s also FDA-cleared, meaning that the FDA has deemed it safe, as it is similar to other cleared products already on the market.

Ryan tested the HigherDOSE Red Light Therapy Hat, rating the ease of use a 5 out of 5. “This red light therapy hat is easy to use, has a built-in timer, and covers the head fully,” he said.

He rated the effectiveness of this red light therapy device a 4 out of 5. “I noticed it reduced hair loss and enhanced hair growth. My hairline has improved, and overall, I feel like my hair is healthier,” Ryan said.

“The list price of the HigherDOSE Red Light Therapy Hat is $450,” Ryan noted. “Based on my results, I’d consider this a worthwhile investment. Seeing as this is a one-time cost, I believe it is well worth it. Especially compared to other hair growth options (e.g., supplements or prescriptions) that are subscription-based. I would prefer to pay once and own it outright, rather than paying indefinitely,” he said. Ryan rated the warranty and returns a 4 out of 5, as the warranty is only one year long.

Specs:

• Best for: Professionals who want a discreet way to regrow hair
• Wavelengths: 650 nm
• FDA clearance: Yes, FDA-Cleared
• Treatment schedule: 10 minutes daily for 4 months, then maintenance

Best Red Light Helmet for Hair Growth: iRestore Laser Cap

Our Thoughts on iRestore Laser Cap

The iRestore Laser Cap is our pick for the best red light helmet for hair growth because it has the highest irradiance on our list: 2,500mW/cm². This is a great option if you’ve done the research and want the strongest treatment available rather than a mid-range option. It includes 500 diodes (both lasers and LED lights) and is FDA-cleared, meaning that the FDA has deemed it safe, as it is similar to other devices already on the market.

Ryan tested the iRestore Elite Laser Cap. He rated the ease of use a 5 out of 5. “The device is very easy to use,” he said. “It has a built-in timer (12 minutes), and it fit my head well.”

He rated effectiveness a 3 out of 5, keeping in mind that patience is an important part of red light therapy. “I’ve only been using the device for two weeks,” Ryan said. “It’s been a pleasant experience, but I haven’t noticed any immediate results. The operations guide suggested it can take up to six months to begin seeing new hair emerge, so I’m keeping this in mind,” he said.

“On the brand’s website, the list price is $2,699. The cap is noticeably larger than similar products,” he said. “iRestore also offers a 36-month warranty against defects in material or workmanship. You must validate your warranty. They offer financing programs for 3, 6, or 12 months with 0% APR promotions available,” Ryan noted. Keep in mind that the warranty is three times longer than the HigherDOSE hat. If you’re going to pay a premium, this flexibility and extended coverage are nice to have.

Specs:

• Best for: Professionals who want a powerful at-home red light treatment
• Wavelengths: 650 nm
• FDA clearance: Yes, FDA-Cleared
• Treatment schedule: 12 minutes daily

Best Red Light Shower Head for Hair Growth: HigherDOSE RLT Shower Head

Our Thoughts on HigherDOSE RLT Shower Head

HigherDOSE RLT Shower Head is our pick for the best red light shower head for hair growth because it combines red light therapy with your daily showering routine. It’s a filtered showerhead and also delivers 650 nm of red light for 5-, 10-, or 15-minute increments. This showerhead is a great way to simplify your hair growth regimen without adding an extra step to your day. Keep in mind that this showerhead is not FDA-cleared, so if regulatory clearance is a deciding factor for you, that’s a meaningful difference to weigh against its convenience.

Emily tested this showerhead, rating its ease of use a 4 out of 5. “It was easy to set up in my shower, and I feel like the water pressure significantly improved,” she said. “The red light covers the whole body while in the shower. It was also nice that it came with goggles to protect your eyes.” However, she hasn’t been able to figure out how to use the remote control. “There is a power button on the actual showerhead, which allowed me to still use it; I couldn’t pick the amount of time,” Emily said. 

When it comes to effectiveness, Emily rated the HigherDOSE RLT Shower Head a 4 out of 5.
“I haven’t noticed significant improvements in my skin or soreness, but my hair does feel softer. I am not sure if this is from the red light or the filter though,” she said. Emily’s uncertainty is a fair warning about the multiple capabilities of this device: since it combines water filtration and red light therapy, it might be tricky to tell what is actually driving your results.

“This product is $599, which feels appropriate for a red light shower head that also doubles as a filter. It is recommended that you replace the filter every 75 days, though, and the replacement filter is $45, which feels a little steep,” Emily said. “Another nice value add for this product is that the charging dock doubles as a red light ring stand so you can use it as a mini desk panel for your face.” She rated warranty and returns a 5 out of 5. “It comes with a 120-day money-back guarantee and a 1-year limited warranty.” If you do add the recurring $45 filter cost into your budget, by swapping five times a year, it will cost about $225 on top of the $599 price. This makes this product closer to a subscription than a one-time cost (like the hat).

Specs:

• Best for: Professionals who want to simplify their hair growth routine
• Wavelengths: 650 nm red and 850 nm near infrared
• FDA clearance: Not FDA-cleared
• Treatment schedule: 5, 10, or 15 minute daily use while in the shower

Why the Right Red Light Therapy Products Matter to Professionals 

The health of your hair is part of your executive presence: appearance matters when you’re at the top. If you’ve experienced some hair loss and want to regrow what you can with the help of hair growth treatments, a red light therapy device may fit well into your wellness routine. 

It’s possible that chronic work stress could contribute to hair loss, so trying a red light therapy hat could help counteract the physical effects of the job. These devices are used for about 10 to 15 minutes a day, so you can add them to your already packed schedule without competing for space.

How We Tested and Selected the Best Red Light Therapy Products for Hair Growth

Here’s what we considered when testing the best red light therapy products for hair growth.

Ease of Use 

Testers considered how easy (or difficult) it was to set up their red light therapy device for use. They also noted how the remote worked and whether the device had a built-in, automatic timer. Our testers rated ease of use on a scale of 1 to 5.

Irradiance and Frequency

Irradiance varied across the red light products that our testers considered, ranging from 5 mW/cm² to 200 mW/cm². Wavelength frequency varied as well, though most products tested were around 650 nm. Our testers rated both irradiance and frequency on a scale of 1 to 5. 

Comfort and Coverage

When testing red light therapy products meant to support hair growth, testers checked to see if the devices fit snugly and targeted their entire head evenly while being worn. They also considered how comfortable the device was to wear throughout the entire daily session. Our testers rated coverage on a scale of 1 to 5. 

Perceived Results

Hair loss treatment is a slow, gradual process, and results rarely happen overnight. Most clinically backed options need consistent daily use for several months before meaningful changes become visible. Our own testing is still in the early stages, so any observations so far are preliminary. As more time passes and we collect longer-term data, updated insights and results will be shared here.

Benefits of Red Light Therapy for Hair Growth

Here are some benefits of using red light therapy devices:

• Boosts blood flow to your hair follicles
• It’s a drug-free way to support regrowing your hair for folks who want to avoid prescriptions
• Red light therapy can also be used in combination with prescriptions to enhance hair growth, if you’d like
• When used properly, low risk of side effects

What to Avoid in Red Light Therapy for Hair Growth

Here are some aspects to avoid when shopping for red light therapy devices for hair loss:

• Red light therapy devices that offer instant or overnight fixes
• Red light therapy devices under 650 nm
• Red light therapy devices without eye protection 

How to Find the Best Red Light Therapy Hair Growth Product for You

Here’s what to consider when shopping for the best red light therapy hair growth product for you.

Your Hair Goals

Here are some questions to consider ahead of purchasing a red light therapy device:

• Would you like to slow existing hair loss or actively regrow hair in areas that have already receded?
• Are your hair loss concerns related to specific areas of your head (crown or hairline) or your overall hair density?
• Do you want a red light therapy device that is for your scalp only, or do you want a multipurpose red light therapy product that you can use elsewhere on your body?

Light Specifications

Check both the irradiance (examples: 5 mW/cm² to over 200 mW/cm²) and the wavelength frequency (aim for around 650 nm red light, plus 850 nm near-infrared) when shopping. It can be difficult to find these numbers on some brands’ product pages, so look for product specs or ask customer service prior to purchasing.

Type of Device

Look for a red light therapy device that will suit your needs. There are red light hats, caps, helmets, and showerheads that are specifically made to support hair growth. If you want a red light therapy device that is more multi-purpose, you could consider looking into panels or a mask. You could also pair your red light routine with a scalp massager to support blood flow to the scalp between sessions.

Fortune’s Final Thoughts

Red light therapy products for hair growth require consistent daily use for several months. They’re not a quick fix and often have a high price tag. We recommend doing your due diligence in researching the irradiance, wavelength, and features of a red light therapy device before purchasing. 

When used in combination with topical or oral hair growth prescriptions, or paired with hair growth vitamins, a red light therapy hat or showerhead may help to grow hair where you’ve experienced loss. We recommend talking with your doctor or other healthcare professional for guidance, as well.
