WHAT THE INFRARED DOES Independent electron-microscope analysis by CIMAV, a Mexican federal research laboratory, compared human hair before and after four passes with a CROC infrared iron at 380°F. The report found the cuticle "better sealed or aligned, resulting in a visually smoother surface." (CIMAV report SEM 20-2453, 3 December 2020.)
