Effects of Ultraviolet Rays and Particulate Matter on Hair Porosity in Damaged Hair

This study investigated the effects of ultraviolet (UV) rays and particulate matter on hair porosity, particularly in damaged hair. The research found that UV radiation increased hair porosity over time, with significant changes observed 3 hours after exposure. While particulate matter alone did not affect hair porosity, its combination with UV irradiation significantly increased porosity. These findings suggest that environmental factors like UV exposure and pollution can exacerbate hair damage, highlighting the importance of maintaining healthy hair to mitigate these effects.
