Extensions or implants, which do you believe is better for having longer eyelashes?

There are implants for eyelashes but they harvest hair from your head and implant it in the lid, down side is that the hair grows longer than the lash necessitating the need to have your lashes trimmed and curled. Won’t trimming the lash leave the ends blunt and thus fake looking? The only other alternative seems to be extensions but they last about 2 months +/- if you baby them, and they cost a lot of bucks for the upkeep. Is there a hybrid between the two, synthetic lashes that an be implanted so you have longer lashes that you won’t have to keep cutting off? And anyone had one or the other and what do you like best about the choice you made out of implants or extensions?
