Air pollution linked to hair loss

Research presented at the 28th EADV Congress in Madrid shows for the first time that exposure to common air pollutants known as particulate matter (PM) is linked to hair loss in humans. The Korean study was conducted by exposing cells from the human scalp to various concentrations of PM10-like dust and diesel particulate. Results showed that the presence of PM10 and diesel particulate decreased levels of β-catenin, the protein responsible for hair growth.
