I like wavy hair, personally. When I was younger I actually got a perm once a year because my hair had almost no waves. After moving 25 years ago, I lost my hair dresser and started doing everything myself, so no perm. Now my hair has natural waves. I spritz with Royal Hawaiian Sandalwood hydrosol and scrunch and get nice waves (not quite as nice as Keri Russel, though).

You look nice either way, so do whatever makes you feel good or mix it up occasionally.
