CurrentBody LED Hair Growth Helmet Review: Hairy Babies (2026)

Almost everyone I know he’s unhappy with their hair in some way. All my straight-haired friends want curly hair, and all my curly-haired friends want straight hair. I’m very jealous of people with thick hair, as well as people with fine, thin hair that gets tangled easily.

My hair also grows very slowly. I got a short haircut in the spring of 2011, and my hair didn’t touch my shoulders until the end of 2013. Plus, because my hair is so thin, when I pull it back, it separates, and you can see my scalp underneath. Because it is so soft, it tangles and breaks often, leading to chronic dry ends.

In general, I’m unhappy with my hair and its lack of growth or fullness, so I wanted to see if CurrentBody’s Bluetooth Wire-Free LED Hair Growth Helmet would solve a slew of hair issues. Similar to red light therapy devices for hair Red light therapy masks For your face, using red lights to increase hair growth and promote a healthy scalp. You need to use the device for just 10 minutes a day, and CurrentBody claims that you will see results within 12 weeks. Although my results weren’t very visually dramatic, I did notice that my hair felt thicker while shampooing, and I saw a lot of “baby hair” appear at my hairline after about three months of testing.

Unlike more discreet red light hair growth devices, e.g Hair Dose Red Light Hat (See our full review here), the input of the CurrentBody is a complete helmet, lined with 10 strips of 12 red lights each with a 620 to 660 nm range (nma unit of measurement for the wavelength of visible light). This works similarly to Red light therapy facial maskswhich aims to improve skin condition and stimulate new cell growth using red light therapy in the mid-600 nm range. 620nm red light helps improve scalp health by promoting blood circulation, and 660nm red light goes deep, reaching through the epidermis and dermis to the subcutaneous, where it stimulates growth and repair at the follicle root.

Red light wavelengths are clinically proven to stimulate hair follicles; Improve blood flow in the scalp. Reduce inflammation. Low dihydrotestosterone (DHT) Hormone levels that cause hair loss and thinning. Supporting the production of adenosine triphosphate (Professional tennis players) which helps store and release energy into cells. This wavelength of red light stimulates follicles to remain in the hair growth phase by providing oxygen and blood flow to the scalp.

Rinse, red light, repeat

The helmet is FDA approved (meaning it has been determined to be equivalent to a legally marketed similar device) and is FSA (Flexible Spending Account) or HSA (Health Spending Account) righteous With a letter of medical necessity. It comes in two sizes: medium for a skull circumference of 21.3 to 23.2 inches, or large for a skull circumference of 23.3 to 25 inches. (I chose the medium, and it was still too big for my head.) The device sits on a dock and charges via a USB-C cord. It takes about three hours to fully charge the helmet, 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 below the charging port.
