Looking forward to seeing this movie. It's full of curlies! John C. Reilly, Jonah Hill as male curlies, and Marisa Tomei has a head full of curls, too.

She says her hair was curled up, but that her hair is very wavy naturally. The USA Today calls her onscreen character's hair "puffy," which seems pretty yesteryear since so many characters have lovely curls on TV and film nowadays.

USA Today:

IMDB has more hair shots, here's one I like:
2b/3a, fine, "naturally frizzy", non-porous, above shoulders, brunette
Low-poos--faves are Deva and JC, experimenting with CJ Gentle Cleansing Shampoo
Conditioners: faves are Devacare One-C, Jessicurl Too Shea
Leave Ins: Conflicted relationship--no fave
Fave stylers: Aveda Flax Seed & Aloe over Aveda Phmollient mousse, KCCC over anything, Biolage Firm Hold Gelee (HG for spring/summer), CK
