Taylor Swift [1] has been channelling a unicorn-inspired style to promote her upcoming Lover album, and it's included a bevy of hair colour changes [2]. The singer first unveiled a pastel pink bob [3] in her video for "Me!" and later wore a rainbow wig in her video for "You Need to Calm Down." [4]

More recently, Swift posted a photo of herself to Instagram with dip-dyed blue ends and a glittering heart painted around her eye, and her hairstylist Riawna Capri [5] just posted another image of the singer with pink ends.

If you're wondering how Swift is changing up her look so quickly, we have a hunch. It's possible that she's been using temporary, wash-out colour (like the L'Oréal Paris Colorista Spray [6] ($5, originally $7)) to achieve the pretty pastel hues. Regardless of how she's doing it, we can't wait to see what colour she'll try next.
