Eyelash extensions

So I've been using eyelash extensions for about 2 months before the whole quarantine thing started. My last fill was about a month ago. Now that most of the extentions fall off, I noticed my real lashes are waaaaay shorter and thinner than what they used to be. I also have been using latisse way before the extentions (which worked amazing) and while having them on as well, but it seem despite that my lashes are just so short now. I also take good care of my lashes, rarely if ever wear eye makeup since getting them, and cleanse them regularly.

What do you ladies do to care for your lashes while having extentions?
