I'm pretty sure Meg Ryan's hair is naturally wavy, but that particular style probably had some help from a curling iron. Like someone else said, actresses have to have consistent hair for multi-day shoots and we all know how wavy hair can vary dramatically from day to day...

It is absolutely gorgeous though, I wish my hair would do nice regular waves like that! Instead I have spots that are 3a corkscrews and others that are almost straight ... and the exciting part is I never know which part will do what on any given day!
