what do you think the process is of doing lana's evil queen hair?

i just now asked a similar question about ginny's snow white hair but now i wanna know about the process of doing lana's hair as the evil queen. i mean like ginny, lana's hair is shorter then her character seen in the enchanted forest. i mean is it a wig? extensions? i mean i've seen scenes in episodes where it really does look like her hair! most notably when regina has it just plan down. it doesnt look like its even possible that she's wearing extensions or anything but she must be since her real hair is shorter. i would really love to see a video of the process of doing both ginny's and lana's hair for the enchanted forest scenes!
