Especially since western film makes it hard for actresses to keep very long hair.
Phoebe Thomas - English actress who had classic length red hair for a while
Sophie Marceau - Rumor has it that she wasn't wearing a wig in Braveheart.
Julie Ormonde - beautiful long hair right up until Sabrina. In First Knight she was epic. Possibly assisted by extensions, but maybe not
Madeleine Stowe - had thick long hair back in the 90's
Amanda Seyfried - got it about as long as hollywood would allow back in Gone. Kind of counts?
Danielle Fishel - had hair past her hips until the show she was on made her cut it
Danielle Chuchran - once claimed while her hair fell to her waist that she'd been terrified when, for a movie, she'd been made to have a foot cut off. See what I mean?? Freaking hollywood. It was waist length AFTER that cut.
Ashley Slalina-Davies - UK Soap actress with flowing hair for a while (until once again it was cut off for the show she was on)
Kristina Wagner - had gorgeous blonde hair to her hips on a soap opera in the 80's. Too gorgeous, because once again, off it went in one episode, likely for a ratings boost.
Russia/Ukraine/Poland - check here. tons of long hair past waist, thick as waterfalls. Those countries know what's up when it comes to long hair!
