Air pollution can cause hair loss
We know that dirty air damages our lungs and poses a serious threat to our health in general. It looks like air pollution can also cause hair loss and baldness. A new study found that exposure to common pollutants is associated with hair loss in humans.

We know that dirty air damages our lungs and poses a serious threat to our overall health. It looks like air pollution can also cause hair loss and baldness. A new study, presented at the European Society of Dermatovenereology Congress in Madrid this week, showed that exposure to common pollutants is associated with hair loss in humans.
In a new Korean study, scientists exposed cells taken from the bottom of scalp hair follicles to microparticles that pollute the air from traffic and industrial operations.
The results showed that exposure to PM10 microparticles (10 micrometers or less) and diesel combustion products reduced levels of β-catenin, a protein responsible for hair growth. The scientists also found that three other proteins (cyclin D1, cyclin E, and CDK2), which are responsible for hair growth and maintenance, were reduced by the same substances.
“While the link between air pollution and serious diseases such as cancer, chronic obstructive pulmonary disease and cardiovascular disease is well established, there is little research into the effects of specific substances on human skin and hair,” says lead author research by Hyuk Chul Kwon of the Future Research Center in South Korea.
According to the authors, their work explains how air pollutants can act on hair follicle cells and lead to hair loss. Research has shown that the risk of baldness is dose-dependent, meaning that increased pollution leads to increased hair loss.
The investigated microparticles are a mixture of solid particles and droplets found in the air. These pollutants fall into two categories: PM10 (particles with a diameter of 10 micrometers or less) and PM2.5 (particles with a diameter of 2.5 micrometers or less). Both PM10 and PM2.5 are considered major air pollutants and are associated with a variety of serious diseases such as heart and lung disease, cancer and respiratory diseases. These particles are formed from the burning of fossil fuels such as gasoline and coal, and from the extraction of minerals and the production of building materials such as cement, ceramics or bricks.
