Britney's hair is very iconic. She's known as the platinum blonde all american girl.

Rihanna because it defined an entire era (LOUD). She was consistent with it and it made her Rihinvention for the LOUD era cohesive. Katy's blue wig was just for 'California Gurls' and Gaga's hair bow just popped up here and there during The Fame era. But neither Katy or Gaga were consistent with the looks. Rihanna was. That red hair reminds everyone of her fifth album, and she'll never bring it back because it represents LOUD and LOUD only.

"Wow, Christina is such a great example in terms of success. It's 2011 and I want to just as successful as Christina Aguilera is! She is so successful. I wonder what's the recipe. Let me try the hair! I'm inspired by Christina Aguilera because I've seen it work out greatly for her, since she's so successful."

Blue before Katy -



Red before Rihanna -



By default this makes X hair overall iconic.
