Nails (More beauty threads.)
What kind of condition are yours in?
Mine are always short (not shorter than the length of my finger) and never seem to grow. But are always painted. I have nail varnish of almost every colour.
I went through a phase a few years ago of putting on false ones, but they are impossibly impractical, quite expensive to upkeep and don't even look that nice to make them worth it.
