I have chronically dry hair that grows at a snail's pace. When it does get to my desired length, the ends split and I'm left needing to cut, essentially negating all of the new growth. My hair is also very thin and tends to tangle, resulting in breakage and large chunks that pull out when I brush. While I've mostly given up on my quest for Rapunzel-length hair, I do want to ensure that I'm doing what I can to cultivate a healthy scalp for new hair growth.

I previously tested the CurrentBody LED Hair Growth Helmet, a large, Bluetooth-enabled helmet that uses infrared LED lights to spur hair growth and promote scalp health when used consistently for 12 weeks. Rather than a large red-light wearable (like a red-light therapy mask), the Laduora Duo 4-in-1 Red Light Therapy Scalp and Hair Care Device utilizes the more familiar style of a hairbrush, and uses not only red-light therapy to support hair growth but also incorporates microcurrents, sonic vibration, warmth, and a serum.

So, did all of these extras actually give me longer, thicker hair worthy of a Danielle Steel book cover? Not exactly. I didn't notice my hair growing longer, but I did see baby hairs sprout on my hairline, and the pod serums helped smooth flyaways. It's not your grandma’s hairbrush – it's a complex device with multiple functionalities.

The Laduora Duo aims to support stronger, thicker hair in multiple ways: red-light therapy at 660 nanometers, microcurrents at 330 to 400 microamperes, sonic vibration, warmth, and a serum. Laduora claims you'll see results in as few as four weeks by using the device for five minutes daily, though as you get used to it, you can use it for up to 30 minutes daily.

It's an interesting blend of science and technology aimed at hair care, but may I suggest a bit more TLC with a proper brush and conditioner?
