Standardroutine zum Schutz der Haare vor Wärmeschäden kann gefährliche Emissionen verursachen-nur 10-20 Minuten Styling mit gemeinsamen Produkten führen zu rund 10 Milliarden ultrafeinen Partikeln, die direkt in die Lunge eingeatmet werden-ähnlich wie das Stehen neben einer geschäftigen Straße in der Spitzenstunde oder das Rauchen mehrerer Zigaretten.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

Indoor Nanoparticle Emissions and Exposures during Heat-Based Hair Styling Activities

From the linked article:

This daily routine sends billions of hazardous nanoparticles into the lungs

For the first time, scientists quantify the health risks of hair styling

**A standard routine to protect hair from heat damage is actually turning your bathroom into a dangerous emissions zone, as scientists find that just 10-20 minutes of styling with common products results in some 10 billion ultrafine particles being inhaled straight to the lungs – akin to standing next to a busy road in peak hour or smoking several cigarettes.**
