Heat-Based Hair Styling Emerges as a Major Indoor Nanoparticle Pollution Source, Study Reveals
A newly published study in Environmental Science & Technology has uncovered surprising risks associated with common heat-based hair styling activities, such as straightening, curling, and waving. Researchers from Purdue University found that these routines can generate astonishing concentrations of airborne nanoparticles, identifying a significant but previously overlooked source of indoor air pollution. The investigation measured emissions […]
