Eye doctors are warning women who get eyelash extensions about the danger of getting lice.
Optometrists say they are seeing more cases of "lash lice" due to the new trend. The reason? Many people are afraid to wash the lashes in case they fall out.
Experts say that not washing them can increase bacteria and lead to infection. Even worse, lice can show up and they can spread.
Doctors say cleaning is critical.
"We recommend tea tree based cleanser," Dr. Sairah Malik said. "Any cleanser that has a diluted form of tea tree. And it is a good idea to use it on a daily basis."
Doctors also say that it is a good idea to give your eyes a break from lash extensions every now and then.
