I think "busy" styles are best left to kids and young girls. I saw this older black lady today that had one of those fake spiral ponytails on top of her head and it was gray to match her real hair. I had that exact style when I went to my senior prom!
Excessive beads, barrettes, 50-11 accessories, etc. also look pretty silly on someone grown.
I just think as you age your styles should become more classy, sophisticated, and sleek.
On the other end, I don't like seeing little girls with grown up hairdos.
