When people talk about to eyelash lice, they are actually referring to mites, which are known medically as Demodex. "Demodex mites are tiny mites that live around hair follicles," explains Dr. Shotter. "Since eyelash extensions have boomed in popularity, so has a rising problem with Demodex mites living in the eyelashes," she continues.
"True eyelash lice are very uncommon and are normally transferred from the pubic area." Demodex mites, on the other hand, can be found all over your body and are often the cause of rosacea.
