When you spend anywhere between $100 to $150 for a set of eyelash extensions, chances are you want them to last as long as possible. But if that’s just not happening and you are a fitness buff, there could be a very simple reason: your workout. If you enjoy a postgym sauna session or are a fan of hot yoga, you could be damaging the bonds of your lash extensions, which may make the hair fall off earlier than you expected.
Hanna Putjato, CEO of London Lash Pro, spoke to POPSUGAR and explained that these warm environments can be damaging because most lashes are applied using a cyanoacrylate-based adhesive, which can soften in higher temperatures — a reaction she calls thermal decomposition (or bond breaking). Since saunas can range from 140-215 degrees, “the lash glue can become softer and lashes might fall out faster after visiting the sauna,” she said.
However, if you’re not ready to cancel all your upcoming hot yoga sessions, there may be a few things you can do. Putjato recommends not touching or rubbing your eyes while you’re in the warm environment or immediately after, since leaving the extensions alone allows the glue to cool down and polymerize again. Having said this, prolonged use of hot activities could mean your lashes may not last as long as they normally would without them — so feel free to use this as a good excuse to exercise near an A/C unit.
