has anyone successfully made their lashes thicker/longer?

Hi, i have naturally downturned, straight, short, thin lashes… i use to get a lash lift but it honestly never did much…. i tried lash extensions years ago and didn’t know there was different kinds aka clusters vs singles.. i had clusters they were WAY to heavy for my eyes and completely ruined my lashes when i asked them to remove them after 2 weeks instead of doing a refill… my lashes “grew back” as in they were still the short straight lashes i knew.

I’ve tried grande lash but it was making my eyes red so i stopped before i could see results. My friend uses this tho and her lashes grew soooo long and pretty! I’m just worried because i have binocular vision dysfunction and I don’t know if it would mess with that!

Recently in the past month i’ve gone back for extensions after YEARS of trying random serums from walmart.. or even a castor oil recommendation from my esthetician.

nothing has done ANYTHING

i’ve gotten my single lash extensions refilled once so far… but tbh it’s not even the money that’s the issue it’s more so time consuming and how often they get sparse!! sitting in a chair with my eyes closed for almost 3 hours every 2 weeks for $70. I’m also very worried about my nature lashes being completely ruined. I follow the care instructions but i can’t help but wish my natural lashes were thick and long!!

before the extensions i have now i can curl them good with a curler as they are and add water proof mascara but they still just look stubby!!

any recommendations?
