This one would certainly require several different nail brushes and polishes, but the end result is breathtaking. Not for someone just beginning with nail art, however.
This one would be perfect for anyone, no matter how unsteady your hand is - just paint with a solid neon color, then use a Q-tip and another polish to make zig-zag lines across the nail.
This one's another time-consuming, but gorgeous option. A coat of neon, a layer of glitter, and finally, the nail stickers and rhinestones.
These fishtail-inspired nails have to be my favorite. It would really only require three polishes and a nail brush, but the finished product looks like a million bucks.
