Let's review the celebs who've worn or are currently wearing this attention-grabbing look.

Katy Perry is definitely the clearest example. She's worn her hair all kinds of colors - pink, blue, and right now, purple. But even when she had natural brown hair, she couldn't resist adding a few colorful streaks, like you can see in photo 7.

Selena Gomez also tried out this trend. For a few weeks, she was wearing dark purple streaks. But it didn't last too long - she changed it up again and is now rocking a lighter brown shade than usual for summer.

Jessie J tried out purple too, but instead of wearing streaks, she went for a head of hair that was half purple, half brown.

And the latest stars who've tried out this look are Ashley Tisdale, Demi Lovato, and Vanessa Hudgens.

Demi Lovato dyed her tips pink just a couple weeks ago.

Ashley Tisdale went for a similar style, but she dyed less of her hair.

And Vanessa Hudgens added a few blue-purple streaks to her mane of hair.

Wambie girls, what do you think of this trend? Would you rock colorful streaks in your hair?
