Health & Fit Hair Loss May Be Linked to Air Pollution, According to New Research
New study links air pollution to hair loss
New research has uncovered another negative effect of air pollution on our health, finding that exposure to common air pollutants could cause hair loss.
We all know that air pollution can be detrimental to our health in a myriad of ways, perhaps most notably to our respiratory systems. According to, however, the negative effects of air pollution may also extend to our scalp (which, when you think about it, makes perfect sense). Scientists found that exposure to common air pollutants (called particulate matter, or PM for short) could be linked to hair loss.
To study this, researchers exposed cells from hair follicles to different levels of dust and diesel PM for 24 hours. Afterward, they measured different protein levels in the cells and found that both pollutants decreased the level of a specific protein that is responsible for hair growth (that specific protein, for those curious, is called β-catenin). In other words, they found that air pollution zaps the protein that fuels hair growth from your follicles, which leads to.

"The research found that when the cells on the human scalp were exposed to common air pollutants created from burning fossil fuels, the proteins in the cells that are responsible for hair growth and hair retention were significantly reduced," study leader Hyuk Chul Kwon tells Allure. Chul Kwon, who presented the findings at the 28thCongress in Madrid last week, says, "The more pollutants that the cells were exposed to, the bigger this impact seemed to be."
What exactly is particulate matter (PM), and what does this research mean for those of us who live in large cities? First off, PM is "made up of small solid particles and droplets in the air that we breathe," explains certified trichologist Michelle Blaisure. PM is all of the gunk in the air that constitutes what we consider to be air pollution, otherwise known as "that haze you see in the atmosphere on bad air quality days," Blaisure says.

In Blaisure's opinion, these study findings aren't surprising — but that's not to say that they aren't concerning. "We know that the health of your scalp skin is important in healthy hair growth and pollution can be detrimental to your skin," Blaisure says. "If the skin is compromised, the hair follicle can be affected as the follicle is an appendage of the skin."
Board-certified dermatologistagrees, saying that "although the study's findings are interesting, it's important to remember that this is a laboratory study." Why? Because, as Mudgil points out, "in the actual human body, there are a lot more variables at play."
For starters, one of those variables is that "the skin is a barrier designed to protect from outside invaders," Blaisure explains. Second of all, this is where your hair-care routine comes into play; Just like you (hopefully) wouldn't go to sleep without cleansing the day’s grime off of your skin, the same should apply to your scalp — which is also skin. "It is important to shampoo and use exfoliating products on a regular basis to keep your hair and scalp healthy and free of toxins and pollutants," Blaisure advises.

Lastly, it's also important to remember that the "research was undertaken in a laboratory," Chul Kwon points out, wherein pollutants were directly exposed to the cells from hair follicles for a period of 24 hours. Therefore, "further research needs to be undertaken to understand just how quickly this affects people regularly exposed to pollutants in their day-to-day lives," Chul Kwon says.
Still, the bottom line here is that this research provides new insight into the many ways in which air pollution can harm our health.

In France, air pollution kills (almost) as much as alcohol
The sanitary weight ("burden") of this pollution linked to human activities (transport, industry, heating with fossil fuels such as fuel, agriculture ..), estimated at 48,000 deaths per year, corresponds to 9% of mortality in continental France, according to the impact study of Public Health France (agency resulting from the merger of the Institute of health monitoring with other organizations, ed).
"the burden of air pollution is ranked third, behind that of tobacco (78,000 deaths) and alcohol (49,000 deaths)," said Professor François Bourdillon, director general of this public body.
34,000 preventable deaths
This pollution represents "a loss of life expectancy for a 30 year old who can exceed two years", according to the study confirming its important role on mortality. While the loss of life expectancy is, on average, higher in large cities (15 months or more), it does not spare rural areas (9 months).
Improving air quality would yield significant benefits, depending on the scenarios considered in this work. Thus, more than 34,000 deaths would be preventable each year, if all the communes of mainland France managed to reach the levels of fine particles of the 5% of the municipalities equivalent (size of population) least polluted. People aged 30 would earn on average 9 months of life expectancy, adds Mathilde Pascal, epidemiologist of Public Health France. This gain would exceed one year in the most polluted areas (19.6 million inhabitants).
Chronic exposure more harmful than pollution peaks
The mortality figures of this new study, are of "the same order of magnitude and confirm" the previous results, without it being possible to speak of an increase, according to Sylvia Medina, coordinator of the Air Santé program. The French study confirms the European study Cafe (Clean air for Europe) of 2000 which estimated at more than 40,000 the number of deaths related to pollution in France.
Levels of pollution (PM 2.5) were estimated in 36,219 communes, bringing together 61.6 million inhabitants, for the years 2007-2008 (excluding Corsica and Overseas). Fine particles with a diameter of less than 2.5 microns (PM 2.5 plugs) serve as a "tracer or indicator of air quality". Pollution peaks weigh less on health than chronic exposure, says the study.
