Taking care of my ugly nails

Ever since I was young, my fingernails have had a tendency to spread out to the sides. To put it simply, you could call them fan-shaped. I always kept them long because I heard that cutting them short makes them look shorter, but it didn't really have any effect. So lately, I've been using a nail strengthener, and while it doesn't have a dramatic effect, I feel like it's improving a bit.
