COURTENEY,LISA,JENNIFER HAIR
I haven't seen thos episodes you were talking about yet, but as everyone knows, she wore fake hair in every episode for the whole season 5, because her hair in private pics were a short page. I thought it was such a stupid decisions by the execs (?) that Phoebe couldn't wear it short like Lisa. I wonder who was behind that decision. In the beginning of season six her own hair was long enough so she didn't have to wear the extensions, but maybe se has gone back to shorter now, I don't know.
well, Rachel's hair switched from long to short in 614. i noticed she got like 3 inches cut off the bottom. i dunno about monica. but Phoebe has to wear extensions because her hair is about up to her chin. or it was when she had her baby.
I think they want Phoebe to have that neo-hippy look, she'd look too modern with her own sleek short hair.
