In 2025, red light therapy has become a go-to solution for a wide range of beauty concerns—from acne and uneven skin tone to textured skin. But its benefits don’t stop there; it’s also gaining popularity for encouraging faster hair growth. According to Dr. Karan Lal, a double board-certified dermatologist, the most effective way to address hair loss is with a multifaceted approach that includes supplements, medications, and light therapy tools. To further support your scalp, you can incorporate products like hair serums, growth oils, and volumizing shampoos, all while giving your scalp regular red light therapy sessions.
Hair loss can stem from many factors—stress, traction alopecia, or genetic conditions like male- or female-pattern baldness. Pinpointing the exact cause can be tricky, but red light hair growth devices have shown promising results regardless of the underlying issue. Just keep in mind: this isn’t a quick fix. Like most skin and hair treatments, consistency and patience are key. Some users start to notice improvements in just a few weeks, as red light boosts circulation and reactivates dormant hair follicles, resulting in fuller, healthier hair over time.
That said, these devices can come with a hefty price tag, and not all are equally effective. To make your decision easier, we consulted with top dermatologists and analyzed countless user reviews to compile a list of the eight best hair growth devices available today—along with expert advice on tackling hair loss head-on.
CurrentBody Skin LED Hair Regrowth Device
Scott Lacey, describes this hair regrowth helmet as “very easy to use and comfortable.” It works by using red light therapy to reactivate shrinking hair follicles, helping stop hair loss and encourage regrowth. According to Dr. Finney, a cosmetic dermatologist and hair loss specialist from New York, “The CurrentBody device is powerful, hands-free, and even comes with Bluetooth speakers—which is a really nice bonus.”
You only need to use it for 10 minutes a day, and clinical studies have shown it can help reverse hair loss in about four months.
- Red light wavelength: 640nm
- Recommended use: Daily
- Customer rating: 4.6 out of 5 stars
One happy customer shared:
“It’s super easy to use and fits perfectly. I love how the timer and Bluetooth connect on their own. It’s light, comfortable to wear, and the materials feel strong and well-made. The light gives off a gentle warmth that’s really pleasant.”
Theradome PRO Laser Hair Growth Helmet LH80
This helmet doesn’t claim to work overnight, but it does promise faster results than many other hair growth devices. Using laser technology, it helps improve hair thickness, volume, and encourages new growth—sometimes in as little as one month. Unlike most devices that need daily use, the Theradome only requires 20-minute sessions twice a week.
Dr. Karan Lal also recommends it, saying, “The Theradome PRO LH80 is easy to use and offers a painless at-home treatment.”
- Red light wavelength: 680nm
- Recommended use: Twice a week
- Amazon rating: 4.3 out of 5 stars
Here’s what one Amazon reviewer had to say:
“This helmet saved my long, beautiful hair. I lost a lot after finding out I had a brain tumor and going through surgery. I had bald spots and thinning on top of my head, and nothing worked for over a year. But after 3 months with Theradome, I started seeing baby hairs come back. Now, after a year of use, my hair is about 80% back and still growing. I never want to be without this helmet!”
HigherDose Red Light Hat
This red light therapy hat is a great low-key option that’s still very effective. It only takes 10 minutes a day and is designed to help with hair loss in both men and women. Most users start noticing new hair growth around five to six months of regular use. At first, you might see a bit more hair falling out than usual—but that’s normal. According to the brand, it just means the weaker hairs are making room for stronger, healthier ones.
- Red light wavelength: 650nm
- Recommended use: Daily
- Customer rating: 4.9 out of 5 stars
One user shared:
“Before using this hat, I used to lose handfuls of hair in the shower. Now, I notice a lot less shedding. My scalp isn’t as visible anymore, and I can see new hair growing in!”
Aphrona Advanced Hair Regrowth System
If you’re looking for a more affordable option, Aphrona’s FDA-approved red light therapy cap is a solid choice. Even though it’s budget-friendly, many users say they started noticing results just a few weeks after using it. All you have to do is wear it for 30 minutes, three to four times a week.
- Red light wavelength: 650nm
- Recommended use: 3–4 times a week for 30 minutes
- Amazon rating: 4.4 out of 5 stars
Here’s what one Amazon reviewer shared:
“I’ve been using this red light hat for six months and wanted to leave a review. I’m in my mid-40s and started losing more hair than usual. Since I had a good experience with red light for my face, I decided to try this for my hair. I felt a slight tingling when I used it, and I could easily wear it while working from home or doing chores. After about two months, I noticed some new hair growing on top of my head. I stopped using it for a month while traveling and did see more hair falling out again. Once I got home and started using it again, my hair looked fuller and healthier in my latest photo.”
HairMax Hair Growth Laser Band 82 ComfortFlex
This device looks like a large headband, and it works hard to reduce and even reverse hair loss. Whether you’re using it as a preventive tool or to treat thinning areas, it uses red light therapy to help support hair growth.
Dr. Finney recommends it especially for people in the early stages of hair loss—especially those with thick hair—because the built-in teeth part the hair, making it easier for the light to reach the scalp.
- Red light wavelength: 655nm
- Recommended use: Three times a week
- Amazon rating: 3.9 out of 5 stars
Here’s what one Amazon reviewer had to say:
“This device is really good and works fast! I saw results pretty quickly—my hair started growing back and getting thicker. It even seems to be helping my grey hairs turn back to their natural color. I love it and definitely think it’s worth the money!”
iRestore Essential Laser Hair Growth System
If you’re unsure about spending money on a hair loss device, the iRestore makes it easy to feel confident. Clinical studies showed that 100% of men in the trial saw noticeable results. Plus, if you’re not happy with it, you can return it up to six months later. The device is comfortable to wear, with soft padding and hands-free design, so you can go about your day while using it.
Dr. Lal says, “I like the iRestore Essential. My mom uses it, and it’s very comfortable and simple to use. It has both laser and LED lights, is affordable, and the company responds well to customers.”
- Red light wavelength: 655nm
- Recommended use: Three times a week
- Amazon rating: 4 out of 5 stars
One Amazon user shared:
“I’ve been using iRestore for almost two months along with Rogaine once a day, biotin vitamins, and alternating hair-loss shampoos. I thought using everything together would work best. I’m happy to say my hair is growing back nicely. I’m no longer embarrassed about my hair because I see lots of new baby hairs that are my natural dark color—not the white that most of my hair is. I believe the iRestore helmet is the main reason—it’s working better than Rogaine alone did for me before.”
HairMax Ultima 12 LaserComb
This isn’t just any comb—it has 12 medical-grade lasers that shine directly on your hair follicles to help make your hair thicker and stronger. Unlike the hands-free caps, you need to hold and use this comb yourself, but it’s great for reaching spots your cap might miss.
- Red light wavelength: 655nm
- Recommended use: Three times a week for 8 minutes each session
- Amazon rating: 3.9 out of 5 stars
One user said:
“I was surprised it really worked! My hair went from thin and fragile to much thicker, and I even noticed new baby hairs growing. I’m really thankful for what this comb has done.”
Breo Scalp3 Scalp Massaging Brush
Massaging your scalp every day helps increase blood flow, which supports hair growth. Adding oil to your scalp is helpful too, and this brush lets you do both at the same time. Plus, it includes red light therapy to boost hair growth even more.
- Red light wavelength: 850nm
- Recommended use: Daily
- Amazon rating: 4.1 out of 5 stars
A happy customer shared:
“I love massaging my scalp with this. It feels great and applies oil while using red light therapy. I totally recommend it!”
