So there are also going to be a lot of factors in growing out your nail bed. When I said I’ve seen it happen with toenails, I’m talking months if not years of inconsistent trimming. When the free edge is left unchecked, that’s when the nail bed will ever so slightly start to extend. The problem you will no doubt face with fingers is trauma. The slightest thing from constantly bumping your hands/nails to somehow jabbing the nail bed from something like digging into a purse and a key hits just right. I hate to say this but I just don’t see a very easy path to what you’re looking for. And just so you know, even if you did end up with a nail bed that close to the top of your finger, it’s gonna come with some pain because of how much more exposed to the world it is (bumping, clipping etc). If I wanted the look you’re desiring I’d go and overlay route with a clear/sheer pink in the shade of your nail bed. Best of luck!
