I have this thing with my nails, especially my thumb and index fingernails where they split on the sides. It's annoying because it splits right on the "quickline" (i'm not sure if that's the official name of the part of the nail, but it splits right where the quick starts). I'm currently trying to grow out my nails to be stronger and longer but when your nails always break at a certain length, it can get really challenging.
noticed my nails are feeling so much stronger. So hopefully as time goes on the problem will go away completely! I've only noticed one split and that's the one on my thumb right now! So fingers crossed it'll go away completely. As far as it making my nail polish stay on longer, meh... it's okay. I would say it lasts just as long as any other basic base nail polish would. I'll give another update later on!
