Red light therapy masks and LED devices for hair growth aren't cheap. These gadgets can cost hundreds, sometimes thousands, of dollars, which is why Amazon Prime Day is one of the best times to buy one. I've combed through the sale to find the discounts actually worth your attention, and every device on this list is one we've tested and genuinely recommend.

You'll also find some noteworthy deals on products that are currently being tested by our WIRED team or are still waiting for a full review, but the discounts were too good not to mention.

Best LED Mask for Quick Sessions

The Dr. Dennis Gross DRx SpectraLite FaceWare Pro has been one of our favorite red light therapy masks for years, and this Prime Day discount makes it a lot more compelling. The hard-shell design is completely cordless, so you can move around the house during sessions. That said, you probably won't have time to multitask, as the treatment sessions last just three minutes. That makes it one of the best ways to squeeze self-care into a busy routine.

At 20 percent off, you're saving $91, which brings the cost below our top pick and many of its competitors.

Best Red Light Therapy Helmet for Hair Growth

The CurrentBody LED Hair Growth Helmet is one of our favorite hands-free devices for hair restoration. After 12 weeks of consistent use, WIRED product tester Molly Higgins spotted new growth along her scalp and sideburns. Her hairstylist commented that her hair felt thicker, and she noticed less breakage and fewer strands getting caught in her brush. She also convinced her balding roommate to try it, and he reported new growth around his scalp, too.

The biggest drawback has always been the price. There are cheaper LED caps and helmets out there, but Prime Day knocks 10 percent off the price, saving you about $90. That's still an investment, but it's easier to swallow if you've been eyeing it.

An All-in-One Facial Device

If you're looking for a facial device that does a little bit of everything, the Lumeo SkinLift 4D Current Red Light Therapy Kit is worth a look. It's a 4-in-1 product that combines red and near-infrared light therapy, microcurrent stimulation, low-intensity electroporation for deeper serum absorption, and massage therapy in a single tool. After two months of testing, WIRED reviewer Molly Higgins noticed her skin looked smoother, brighter, and more radiant overall. While multipurpose facial devices can sometimes feel like they're doing too much, this one delivers a genuinely beneficial experience. The discount helps, too.

Best LED Hairbrush

Like the Lumeo facial device, the Laduora Duo takes a multitasking approach, but for hair growth. The brush-like device combines red and near-infrared light therapy, microcurrent stimulation, sonic vibration, and thermotherapy into a single tool that's easy to work into a daily routine. It also uses serum-filled pods designed to support cell renewal and scalp health. The catch is that you'll need to buy replacement pods directly from Laduora if you want to keep using them. But the good news is that the device still works without the serums.

After four weeks of testing, reviewer Molly Higgins noticed visible improvements in her scalp and hair. The serums left her hair looking shinier, and she started seeing baby hairs sprouting along the crown of her head, with more fullness around her temples. It's also pleasant to use. The combination of heat and vibration makes every session feel like a scalp massage, and a hairbrush is far more convenient than strapping on a helmet.

Fastest Treatment Sessions for Hair Regrowth

Instead of a traditional cap or helmet, this flexible 3-inch headband uses 82 medical-grade lasers (rather than LEDs) to deliver targeted light therapy directly to the scalp. The biggest advantage here is speed. Each treatment takes about 90 seconds, and you only need to use it three times a week. Compared to devices that require daily sessions, that's a much easier routine to stick with. The headband design also lets you focus the treatment exactly where you need it the most. The trade-off is that if you're treating your entire scalp, you'll need to reposition it as you go.

It's definitely one of the pricier hair growth tools out there, but this $170 discount makes the investment a lot easier to justify.
