Skin LED Hair Growth Helmet.

"The CurrentBody Skin LED Hair Growth Helmet claims to increase hair thickness, density and fullness with ten minutes of daily use. It uses 120 LEDs with a wavelength CurrentBody describes inconsistently as 640 nm on the website and 660 nm in the handbook, and its irradiance of about 5 mw/cm2 on the head is on the lower end of the spectrum, with one outside test measuring it even lower at 3 mw/cm2. After six months of daily use she saw no real difference in her frontal hairline, a mixed result on her middle parting (less broadening in the back but more scalp showing in the front), and the biggest improvement on a thinning patch at her right temple, where there was more hair and it felt less fine. Overall she called it a mixed bag, seeing positive changes but only subtle ones and less than she had hoped for, possibly because of missed days, the device's low irradiance, and a surgery and bout of Covid during the test period that could have caused extra shedding. She found the helmet convenient and easy to stick to, but flagged that it is quite expensive at 786 euros, the plastic cracked when dropped since it only weighs about 1.5 kg, the bluetooth speakers felt like more of a gimmick than necessary and caught her hair, the side panel showing treatment duration can't be seen while wearing it, and there is no charge indicator so it can shut off mid session. She said whether it's worth the money depends: it's an option if you have age related thinning without significant hair loss and other treatments haven't worked for you, but topical Minoxidil is better value for money, and since she personally could not tolerate Minoxidil she ended up happy enough to keep using the helmet given the subtle results it gave her."

"LED helmets do help thicken thinning hair. These helmets work by flooding your scalp with non-heat producing LEDs. The energy from these LEDs helps hair follicles enter a growth phase. The CurrentBody LED hair growth helmet uses two clinically proven wavelengths, 620 nm to calm surface inflammation and 660 nm to penetrate deeper, energizing hair follicles, increasing circulation, and stimulating growth. Most other helmets only use one wavelength. The CurrentBody helmet has 120 LEDs for full scalp coverage, and it comes in two sizes, so you'll get a perfect fit. One study showed that in just 12 weeks, users experienced a 123% increase in hair growth and a 26% increase in hair thickness. It's super easy to use: just 10 minutes a day and you can even connect it via Bluetooth to listen to your favorite music or podcast while you treat your scalp. It's FDA approved, HSA, FSA eligible, and it comes with a 60-day money back guarantee."
