The Fame:The Candy Warhol wig,the straight levander one with the bangs and the Paparazzi long bob.
The Fame monster:The classic yellow wig with the locks and the dark roots which she wore at the Monsterball.
Born this way:All the teal wigs and the ones with the cruella highlights.I also like The Marry the night era short blonde bob with the spiky bangs.
ARTPOP:The "Venus" wig (with or without the dark pink highlights),The G.U.Y looong white one,her natural black hair back in the July/August of 2013 and the green wig from the MJH performance of the ArtRave..I know they are a lot but when it comes to Fashion/Make up/Hair i just can't choose!!
