11 best red light therapy hair growth devices, reviewed
Red light therapy hair growth devices are the craze right now, and if longer, thicker hair is on your 2026 wishlist, one of these tools could be the missing piece. If you’re already committed to the best LED face masks or you’re a fan of the best LED neck masks, it makes total sense to bring that same tech into your hair routine too.
Unsurprisingly, one of the most talked-about options is CurrentBody’s LED Hair Growth Helmet. Glamour’s Lian Brooks tested it for a full month and shared her honest thoughts in her CurrentBody LED hair growth helmet review. CurrentBody founder Laurence Newman describes LED hair growth devices as “non-invasive, painless, and free from the side effects often associated with pharmacological treatments,” adding they can be “a fantastic option for many” people experiencing hair loss, and there are, unfortunately, a lot of us.
In fact, research suggests up to 50% of women will experience hair loss at some point, whether it’s down to genetics, conditions like PCOS, autoimmune issues, or even post-COVID shedding. Personally, I’m still not entirely sure what kicked off my own hairline breakage, but after scalp serums and biotin supplements did very little, I wanted to see what red light therapy for hair loss could actually do.
Glamour's best red light therapy hair growth devices, at a glance:
I’ve always been into LED face masks, so trying an LED hair growth helmet felt like a natural next step. Alongside bond-building treatments and shampoos for thinning hair, I’ve been testing and researching these devices for months. With input from experts and the wider Glamour team, many of whom have dealt with hair thinning too, this is my edit of the best red light therapy hair growth devices to buy for 2026.
- What are the leading causes of hair thinning and hair loss?
- What wavelength of light is best for hair regrowth?
- What colour LED light is best for hair growth?
- What kind of devices are best for your scalp?
- Are red light therapy devices for hair loss safe?
- How often can you use red light therapy on your scalp?
- How long does it take to see hair growth with red light therapy?

How I tested red light therapy for hair loss devices:
I have taken care to test as many of the red light therapy for hair loss devices in this edit as possible, as I am well aware they are not cheap purchases. However, it's worth noting that LED masks for the hair and scalp are relatively new to the market, so we are still in the process of testing these over longer periods of time to gauge results. For example, both Sophie Donovan (pictured) – Glamour's Senior Commerce Writer, and Lian Brooks, Glamour's Senior Audience Development Manager, are in the throes of testing the CurrentBody hair growth helmet.
When testing, we have been assessing against a number of functionality criteria, from practical wearability features to the tech behind each device. For example, comfort and wearability are crucial; how does this device sit on the head or get used? Is it handheld, or are there straps to keep it in place? And how does this impact its ease-of-use and practicality?
Testers have also taken note of the wealth of knowledge we have from testing the best LED face masks – and transferring that to their assessment of the potential efficacy of LED helmets. For example, we remember not to be fooled by a huge number of bulbs or multiple colours. Hannah Measures and Laura Ferguson, founders of The Light Salon, said that “clinically-proven wavelengths of light are key; they should be seen as the ingredients you look out for in your skincare, such as Vitamin C, Hyaluronic Acid, Niacinamide. The most clinically-proven wavelengths of light are 633 nanometers & 830 nanometers.” We also look at coverage across the entire scalp, the distance away from the scalp that the bulbs sit, and how often the brand recommends using each device. With all this in mind, we came up with the following shortlist.
Why you can trust me:
It has been my job to test beauty and wellness products for the past eight years – so I've seen an array of beauty trends come and go. I've attended press days, interviewed doctors, MUAs, dermatologists and optometrists – and I've tested hundreds of products. As such, I know more about brands, new releases and which products are worth your money than your average beauty fan.
Red light therapy is a trend that seems to have stuck around, so I've done a lot of research into LED benefits, how to use LED face masks, LED eye masks and LED devices for lips. I've reviewed countless devices, from LED neck masks to the UKLash LED face mask – and I've not given coverage to hair growth devices that I didn’t like. Helmets that have been discounted from appearing this edit, as a result of not passing testing, include the Solaris Laboratories Intensive LED Therapy Hair Brush. Read more about why it wasn't featured.
Editor's note:
September 2025 update: We removed the Solaris Laboratories Intensive LED Therapy Hair Brush from this guide because — although we appreciated the massage and volume right after use — we found that it didn’t thicken our hair the same way that other devices on this list.
Ahead, the very best red light therapy hair devices and LED helmets for hair loss 2026.
CurrentBody LED Hair Growth Helmet
- Type: Hair growth helmet.
- Uses: Red light (620-660nm).
- Treatment time: 10 minutes per day
Why we love it: CurrentBody’s futuristic-looking device is the best red light therapy hair growth device for at-home use, according to our testing. FDA-cleared and backed by board-certified dermatologists, it offers a lazy girl option to hair restoration if you want to regrow hair and go hands free synonymously. Just don't forget to remove it before your work Zoom meeting.
Designed to keep hair follicles in the hair growth phase in order for new strands to grow effectively, the helmet comes in two sizes (small-medium and medium-large) – and is designed to be used for ten minutes per day, emitting a spectrum of red light (620-660nm) to best stimulate hair growth at the scalp. These are the scientifically-backed wavelengths of light which should be used for optimum results via LED therapy.
It has dozens of five star results and reviews (including some that confirm it can be effective for androgenetic alopecia, or female pattern hair loss), and promises a noticeable difference in hair thickness, hair health and hair growth within 12 weeks. The brand has put their device through rigorous testing with clinical trials that suggested an increase in hair count by 33% in only 16 weeks. Lastly? It’s worth noting that this helmet offers full scalp coverage – much more promising than most hair growth serums.

Pros & ConsPros- Offers full scalp coverage.
- 10 minutes per day.
- Promises hair growth within 12 weeks.
Cons- Expensive.
Currentbody LED Face & Hair Kit
- Black Friday deal: The Currentbody LED Face & Hair Kit - worth £1,049, now £755.99.
- Type: Hair growth helmet & LED face mask.
- Uses: Red light (620-660nm).
- Treatment time: 10 minutes per day.
Why we love it: If you’re serious about LED, this is hands down Currentbody’s best deal for Black Friday. In this duo, you’ll get the upgraded Series 2 Face Mask and CurrentBody LED Hair Growth Helmet – so if good hair and skin’s what you’re after, this is the duo to invest in.
Now, we’ve already raved about the helmet, but the viral face mask (yes, the one known for being in that Emily in Paris scene), really is worth the hype. It’s landed number one spot in our best LED Face Mask guide, and Glamour's Senior European Commerce Editor Sophie Cockett, even tested and reviewed the futuristic-looking gadget in her in-depth review.
Dermalux Flex MD LED Light Therapy Device
- Type: Band.
- Uses: 3 clinically proven LED wavelengths: blue (415nm), red (633nm) and near-infrared (830nm) to reduce the visible signs of ageing, redness and hyperpigmentation.
- Treatment time: Daily, in 1 to 30 minute sessions, depending on goals (this advice is for skin).
Why we love it: If money is no object, this Dermalux offering is ‘the world’s most powerful portable LED system for home use.’ And look, it's certainly pricey, but bear with us while we go through its – pretty tempting – specifics.
This device is first and foremost, designed for the face, but because of its shape and size can be used on the body and the hair and scalp, in theory. Perhaps justifying the price a little more, this makes the Dermalux more versatile and thus more appealing – but we'd definitely recommend thinking long and hard about this purchase and possibly trialling too, before you part with your hard-earned cash – as mentioned, it is promoted as a device for the face over anything.
The Dermalux uses blue (415nm), red (633nm) and near-infrared (830nm) light, making it incredibly dynamic and effective for a myriad of concerns.
Pros & ConsPros- Can be used for hair, body and scalp.
- Combines three clinically proven wavelengths
Cons- Expensive.
- Large - takes up a lot of space.
- Type: Cap.
- Uses: Red light.
- Treatment time: 10 minutes per day.
Why we love it: Hands-free, easy to use and – dare I say it – kind of cool, Higherdose's cap is perhaps the most fuss-free way to reap the benefits of red light at the scalp.
Designed to be used once a day for ten minutes per session, the brand promises a number of benefits in increments. During months one to two, for example, you're likely to see an increase in shedding as weaker hairs are replaced with new growth, which is followed by a reduction in shedding and visible new hair growth during months three and four. By months five to six, you'll see even less shedding and more growth, which only continues the longer you use it.
The cap is powered by 650nm red light, which boosts blood flow to the scalp, thus invigorating hair follicles, and therefore reducing shedding and improving new hair growth. Your new favourite accessory? I think so.
Pros & ConsPros- Hands-free, lightweight and easy to use.
- Only 10 minutes per day required.
- 650nm red light targets scalp circulation and follicle health.
Cons- Results take a few months to appear.
- Limited to red light (no multi-wavelength options).
Solaris Labs NY Hair Boost Red LED Hat Supporting Growth
- Type: hair growth cap.
- Uses: Red LED light.
- Treatment time: On clean, dry hair, use the hat for one 10-minute session daily, 3-5 times a week.
Why we love it: A new release which we're in the throws of testing is by Solaris Labs NY – a brand who pride themselves on upgrading modern beauty routines by taking ancient Egyptian techniques and bringing them into the 21st century. The brand stocks a collection of cutting-edge face and body tools that meld holistic practices with new-age technology. And red light therapy is just one example. Built to assist in the maintenance of strong hair and a healthy scalp, the Hair Boost Red LED Hat uses red light to stimulate hair follicles. This cap also uses blue light which is said to soothe the scalp and reduce inflammation. Overall, we love how lightweight this cap feels – and the fact that it's rechargeable, hands-free and easy to incorporate into a already-busy routine.
Pros & ConsPros- Combines red and blue light (stimulates follicles + soothes scalp).
- Lightweight, rechargeable and hands-free.
- Only 10 minutes per session.
Cons- Requires consistent use to see benefits
- Expensive.
- Type: Handheld device.
- Uses: Red LED light.
- Treatment time: daily, in 3-4 minute sessions on each section of the scalp.
Why we love it: For those who want to give LED a go for hair growth and thickness but don't want to spend hundreds upon hundreds, the Foreo Luna 4 Hair is a solid choice. It also allows you to take more of a ‘hands on’ approach if you are keen to include this as part of your self-care ritual.
The device is designed to be used daily, for 3-4 minutes per section of the scalp until you cover your entire head. Its waterproof design means it's easy to incorporate into your existing shower routine, and as well as red LED light, Foreo's tool harnesses the power of T-Sonic™ massage (with 395 ultra-hygienic silicone bristles at your fingertips) to offer a two-in-one red light treatment and massage device for both efficacy and relaxation.
Clinical results by the brand speak to the device's ability to reduce hair loss by up to 41% and increase hair growth and thickness by up to 36%. As well as this, it's designed to target both dandruff and oil-buildup at the scalp, resulting in a healthier, stronger environment for new and existing hair follicles.

Pros & ConsPros- Affordable.
- Combines red LED light with T-Sonic™ massage for a two-in-one treatment.
- Targets dandruff and oil build-up as well as hair growth.
Cons- Handheld design means you have to work section by section (can take longer than a device or cap).
- Results rely on daily, consistent use.
The Light Salon BOOST LED Body Patch
- Type: Handheld device, which also comes with a strap.
- Uses: Red light 633nm and near-infrared light 830nm – “the most clinically proven to promote cellular health, soothe pain and relieve stress,” according to the brand.
- Treatment time: Daily for ten minutes.
Why we love it: The Light Salon's clever patch definitely has a unique selling point: it's so versatile, it can be used everywhere. In fact, the brand proudly proclaims this ‘targets the skin, hair and body from head to toe.' So if you want a device you can also benefit from in other ways, this allows you to get the most bang for your buck.
The device uses red light at 633nm and near-infrared light at 830nm, and has undergone clinical trials to prove its benefits for hair, skin and body. Users reported reduced hair loss following consistent use over just 8 weeks, according to the brand, which promises improved scalp health also.
The device is technically handheld, but it also comes with a strap you can attach pretty much anywhere, including under the chin for use on the head. It can be used a minimum of 3-5 times a week for best results, or daily if you're really committed!

Pros & ConsPros- Can be used on scalp, skin and body.
- Clinically tested red and near-infrared wavelengths (633nm + 830nm).
- Compact and easy to travel with.
Cons- Coverage area is smaller than helmet-style devices.
Solaris Labs NY Intensive Red LED Hairband Supporting Growth
- Type: Wireless LED headband.
- Uses: Red and blue light therapy.
- Treatment time: 10 minutes daily.
Why we love it: A chic hair accessory that doubles as an effective hair growth tool - Blair Waldorf would definitely approve. The headband features red light which wakes up tired follicles and encourages growth while blue light soothes and clams to keep your scalp happy.
It won’t give you magic overnight results, but if used consistently, it supports thicker, healthier-looking hair over time - all good things are worth the wait, right? It’s lightweight, hands-free and rechargeable and stylish enough to wear out the house - a win, win in our eyes.
Pros & ConsPros- Stylish hair accessory & LED device.
- Red and blue LED light therapy.
- Hands-free and lightweight.
Cons- Might not work for every hair type.
- Type: Handheld device.
- Uses: Red light.
- Treatment time: A four-minute treatment, every other day.
Why we love it: Another easy-to-use, handheld device from Foreo, the FAQ 301 harnesses the power of 20 red LED lights (650nm) and offers 6 intensity levels, to stimulate hair follicles and strengthen hair, working to prevent hair loss.
Like its (slightly more affordable) younger sibling, as well as the LED lights, it too features T-Sonic™ massage, providing a pulsating effect (6,500 pulses/min.) which soothes and strengthens the scalp, allowing for healthier growth.
The lightweight and cordless device features an impressive 637 silicone tips and also helps with absorption of scalp products, making it the perfect accompaniment to your favourite scrub or oil.
Pros & ConsPros- Combines 20 red LED lights (650 nm) with T-Sonic™ massage.
- Six intensity levels.
- Lightweight and cordless.
Cons- Only covers a small section at a time, so full-scalp treatment takes longer.
- Requires consistent use to see visible results.
HairMax Laser Hair Growth Band LaserBand 82 ComfortFlex
- Type: Band.
- Uses: N/A, it uses medical-grade lasers.
- Treatment time: 90 seconds, three times a week.
Why we love it: For the busy and time-poor among us, HairMax's laser treatment band may be the answer, largely thanks to the fact you only need to use it for 90 seconds, three times a week.
It can also be worn hands-free, making it a pretty fuss-free device on the whole. Add to the fact it weighs just 6 oz., this is a very lowkey, low-maintenance device.
The product harnesses the power of 82 medical-grade lasers with an energy output of 1230mW, meaning great coverage. It has had eight FDA Clearances, and has 14 Medical Device Licenses, meaning you can feel safe in its use.
Take a look at these Amazon discount codes to shop for the best LED devices for scalp for less.
Pros & ConsPros- Quick 90 second treatment.
- Hands-free and lightweight.
- 82 medical-grade lasers with wide coverage for the scalp.
Cons- Expensive.
- Only targets the scalp (not a multi-use device for skin or body).
- Type: Lasercomb.
- Uses: Red and blue LED light.
- Treatment time: Twice a day.
Why we love it: At just £60, it's easy to see why Skin Gym's cute and clever LED Hair Brush is already on back-order. The affordable device offers light therapy in a unique brush-comb design, which is designed to be used on clean, dry hair twice a day. You simply start at the front of your hairline and sweep backward while brushing, being sure to come into contact with your scalp.
As well as both blue (400-480nm) and red light (620-760nm), the brush uses vibrational massage to stimulate microcirculation at the scalp in order to create a primed environment for healthy hair growth.
This is a great option for those who want something lightweight, Instagram-friendly and somewhat affordable.
Pros & ConsPros- Affordable.
- Combines red and blue light therapy with vibrational massage.
- Lightweight and travel-friendly.
Cons- Requires twice-daily use for best results (time-consuming).
- No hands-free function.
- Less powerful than helmet or cap-style devices.
What are the leading causes of hair thinning and hair loss?
Almost all men, and over half of all women, will experience hair loss in their lifetime – and the most common cause of this hair loss in all genders is “androgenetic alopecia”. Genetics can be at play, of course, and lifestyle factors like pregnancy and stress can lead to hair loss (telogen effluvium is a post-stress form of hair loss), but androgenetic alopecia is the most common cause.
What wavelength of red light is best for hair growth?
For red light therapy to encourage the stimulation of hair regrowth, the optimum wavelength range is considered to be between 620 and 670 nanometers (nm). CurrentBody's device emits a spectrum of red light between 620-660nm which is, more specifically, the most effective within that range.
What colour LED light is best for hair growth?
What are the effects of red light therapy, and how does it work for hair thinning and hair loss? “LED (light-emitting diode) therapy, particularly in the form of low-level light therapy (LLLT), has been studied for its potential benefits in promoting hair growth,” begins Dr. Raj. “This therapy is thought to stimulate hair follicles, increase blood circulation in the scalp, and enhance cellular metabolism, which can lead to improved hair density and thickness.”
He explains that “studies have shown positive results for individuals with androgenetic alopecia (male or female pattern baldness) and other types of hair loss.”
From a trichologist's POV, Kingsley explains that, “there is limited evidence on the guaranteed results of using LED, although there is no harm in trialling this option” as a part of your hair loss/growth journey if you so choose. She echoes the idea that devices using low-level laser therapy (LLLT) [also known as photobiomodulation] have more backing in terms of studies, but that any device is best used in tandem with other hair loss solutions, such as minoxidil, “to gain the maximum benefit.” This way, your hair regrowth journey for thicker hair will not rely on just one thing - it will be part of a full treatment plan.
What kind of LED devices are best for the scalp?
“There are many available on the market, from caps, helmets to combs,” says Dr Raj, who believes the best are “ergonomic, easy to use devices that can be used in smaller areas more consistently.”
As you'll see, many brands offer solutions, ranging from caps you wear on your head, to small handheld devices you massage your scalp with. The latter can help to stimulate circulation at the scalp where hair grows, and can sometimes be used alongside scalp scrubs or oils, making them potentially doubly as effective.
But it's really down to preference and budget in terms of which hair loss treatment is best for you. LED devices just offer a great non-invasive treatment option, no matter which you choose.
Are red light therapy devices for hair loss safe?
Experts I quizzed agreed that genuine, high-quality devices (such as the ones we've reviewed) are safe, and you should not experience unwanted side effects. That said, you must always follow the specific product's instructions.
“Some users may experience mild irritation, redness, or discomfort on the scalp; however, these symptoms are often temporary.” Dr Raj adds that consulting with your doctor or derm is essential if persistent reactions occur.
How often can you use red light therapy on hair?
This is very dependent on your particular device, but in general, “consistency is vital across all home use tech and none more so than with hair growth,” according to Newman, who adds that the CurrentBody Helmet, for example, should be used daily.
Newman explains that “regular usage is key to seeing results, and frequency typically depends on the device type and treatment goals. For example, many LED devices are designed for daily or every-other-day use for 10–20 minutes per session, though specific guidance will depend on the model." He adds: "Consistent use is critical to achieving and maintaining the desired effects, whether for skin improvement or scalp treatments.”
Ferguson and Measures recommend that for their The Light Salon device, you should use it “three to five times a week.” They conclude: “used this often, the number of treatments amounts to 240 a year, making an LED an amazing investment.” Elsewhere, the FAQ 301 device is best used on alternate days.
How long does it take to see hair growth with red light therapy?
Unfortunately, there is no solid answer to this – due to varying factors. “Hair type, the level of hair loss and hair density will all contribute to how quickly you see results,” explains Newman. “Also, you would need to consider any other treatment therapies you are using alongside devices, such as oral minoxidil.”
“Results from red light therapy for hair growth can vary among individuals,” confirms Dr Raj, who adds: “Generally, users may begin to notice improvements within 12 to 24 weeks of consistent treatment. However, the full effects often take several months to manifest.” In other words, it's crucial to be patient!
