Stars never stop experimenting with their hair, whether it's trading long tresses for a pixie cut or going from honey blonde to a vibrant red. And right now, one of the hottest hair trends in Hollywood is punchy highlights in pink, purple, blue, and other bold hues.

Jordin Sparks has sported purple-streaked strands in the past, but went dark all-over for awhile. Now the singer has brought back her violet pieces, which are evenly dispersed throughout her mane of black hair.

On the other hand, Kesha, who is no stranger to beauty and fashion risks, dons just one piece of blue hair in the pic to the left. This style is better suited for commitment-phobes who don't want to have a whole head of highlights since you can opt for a synthetic clip-in.

Other celebrities who have tried out this trend include Britney Spears who sported blue and pink She by So.Cap. USA clip-on extensions in her "I Wanna Go" video, and Lauren Conrad, who debuted her (temporary) pink, purple, and blue-dipped ends on her blog July 2.
