CurrentBody LED Hair Growth Helmet Review: Baby Hairs Abound (2026)

almost everyone I know he is unhappy with his hair in some way. All my straight haired friends want curly hair, and all my curly haired friends want straight hair. I’m as jealous of people who have thick hair as I am of someone who has fine, thin hair that gets tangled easily.

My hair also grows very slowly. I got a pixie cut in the spring of 2011, and my hair didn’t touch my shoulders until late 2013. Also, because my hair is so thin, when I pull them back, they part, and you can see my scalp underneath. Because it is so fine, it gets tangled and often breaks, resulting in dry split ends over a long period of time.

Overall, I’m unhappy with my hair and their lack of growth or fullness, so I wanted to see if Currentbody’s cord-free, Bluetooth-enabled LED Hair Growth Helmet would work for my many hair problems. Red-light-therapy devices for hair are similar to red-light therapy masks for your face, using red light to enhance hair growth and promote a healthy scalp. You only need to use the device for 10 minutes a day, and CurrentBody claims you’ll see results within 12 weeks. Although my results weren’t overly dramatic, I did notice that my hair felt thicker when shampooing, and after about three months of testing I noticed a lot more “baby hairs” growing on my hairline.

Unlike more discreet red-light hair growth devices like the HighDose Red Light Hat (see our full review here), Currentbody’s entry is a full-on helmet, lined with 10 strips of 12 red lights each on a spectrum of 620 to 660 nm (nanometers, the unit of measurement for the wavelength of visible light). It works similarly to a red-light-therapy face mask, aiming to improve skin condition and promote new cell growth using red-light therapy in the mid-600-nm range. The 620-nm red light helps improve scalp health by promoting circulation, and the 660-nm red light penetrates deeper, penetrating through the epidermis and dermis to reach the hypodermis, where it stimulates growth and repair at the follicle root.

Red-light wavelengths are clinically proven to activate hair follicles; Improves scalp blood flow; reduce swelling; reducing levels of dihydrotestosterone (DHT), a hormone that causes hair loss and thinning; And supports the production of adenosine triphosphate (ATP), which helps store and release energy in cells. This wavelength of red light stimulates the follicles to stay in the hair growth phase by providing oxygen and blood flow to the scalp.

The helmet is FDA-approved (meaning it has been determined equivalent to a similar, legally marketed device) and is FSA (Flexible Spending Account) or HSA (Health Spending Account) eligible with a letter of medical necessity. It comes in two sizes: medium, for skull circumference 21.3 to 23.2 inches, or large, for 23.3 to 25 inches. (I opted for the medium, and it was still too big for my head.) The device sits on a base and is charged via a USB-C cord. The helmet takes about three hours to fully charge and lasts for about a week on a single charge. (The white light on the side flashes while charging and turns solid white when the battery is full.) The device is turned on by pressing the single button located below the charging port.
