"Hun har bølger i håret."

Translation: She has waves in her hair.

[ArankaBloemberg]

As in, she has curls?

[fveldig]

Wavy hair is less curly.

[AlatheaAnd]

"She has wavy hair" implies that the waves are natural. "She has waves in her hair" sounds as though her hair has been styled with artificial waves. Does the Norwegian suggest one or the other, or can it be both?
