This Works’ Advanced Red Light System is being promoted at £144, reduced from £244, with a complimentary body wrap valued at £100. The device is marketed for scalp and body concerns, including hair thinning, and uses red and near-infrared light alongside a power serum. This Works cites a 12-week panel of 22 participants, while several users report less shedding, thicker hair and new growth, including one whose hairdresser noticed more baby hairs. One reviewer said the product made hair greasy and recommended using it twice weekly. Competing LED hair-growth devices from CurrentBody and Solaris Labs are also noted.
