Weighing just 7 ounces, the LaDuora is shaped like a compact brush that uniquely combines red light therapy and microcurrent with a scalp massage and therapeutic warmth for the ultimate at-home self-care treat. It is fantastic for someone with a low bandwidth for self-care, as each treatment sesh is only five minutes—and even a busy doctor like Finney highlights it as one of his picks because LaDuora combines several modalities.

Finney says that good scalp care reduces oxidative stress and subsequent hair fall—and using this tool can help promote a healthier scalp. He calls LaDuora a unique red light therapy device because it directly reduces inflammation by combining red light therapy with the scalp massage, warmth, and microcurrent functions.

Using the DUO is surprisingly straightforward. Each kit has two pink and two blue circular pods filled with nourishing ingredients. The pods simply snap into the center of the device. After I hear a clicking sound indicating the pod is locked into place, I remove the six protective caps on the bristles to ensure the serum at the pod’s base can be released. Lastly, to turn on the device, I’ll push the front button, and it powers on.

I appreciate the flexibility of using the device on dry or damp hair, though I prefer to brush onto my dry strands since I find my dehydrated hair soaks up the included serums better. Each device comes with two types of pods called Scalp and Hair Elixirs: Balance, a pink liquid that contains rose, argan, raspberry seed, and castor oil, and Boost, a blue-green liquid that is a blend of vitamin B-3 (sometimes called niacinamide), caffeine, peptides, blue tansy, and green tea leaf extract. (You can purchase replacement pods separately.)

I was also worried the device heating up to 108 degrees Fahrenheit would be overwhelming, but found the warmth was rather relaxing. I also enjoyed the scalp massage functionality because I can feel my light tension headaches start to melt away, so I’ll reach for this device when I’m tired or leading up to my menstrual cycle. If my headaches are rather intense, this tool won’t do much, but for lighter tension headaches it has helped me feel more relaxed.
