Eyelash extensions, when done correctly, should only touch natural lashes and should never cause a stye. Eyelash extensions can cause cross-contamination and the formation of styes. That's why it's essential to never give eyelash extensions to a customer with a stye. You don't want to transfer the eye infection to another customer.
Whether you get a stye or not boils down to hygiene, not an eyelash lift. Eyelash technicians who don't clean well can spread bacteria to your eyelids, making you more likely to get a stye. However, professional eyelash technicians with high hygiene standards won't give you a stye while lifting your eyelashes. The following are the most common types of eyelash extension infections you may notice and their symptoms.
