Why am I losing eyelashes only on the upper eyelids, one eye at a time? (Photos)

Three months ago, eyelashes from my right upper eyelid began to fall out (beginning from the middle, outward) over a few weeks. Only a select few seem to grow back. I have no other visible hair loss anywhere on my body and my lower lid lashes do not seem to be affected. I once had a bald patch on my head at the age of 10 and lost a small chunk of lashes 3 years ago (18). Blood test was healthy. The makeup I have, I’ve been using for years. *I do have asthma and sensitive sinuses.
