The former Lizzie McGuire star showed off her turquoise locks again this week when she appeared on E! News on Monday (6 April) to promote her new show, Younger. And while there's usually nothing better than freshly coloured hair, we have to say, her slightly fading locks looked better than ever.
Hilary, who plays Kelsey in the upcoming American comedy-drama series, has been doing the rounds in the last few weeks attending the premiere in New York last Tuesday and appearing on various shows in the U.S.
And after revealing on The Ellen DeGeneres Show how her dramatic hair makeover was inspired by the ocean (not, in fact, Kylie Jenner's 2014 dip-dye!) we've been keeping a keen eye on her turquoise mane.
Hilary had her hair coloured three weeks ago at top, West Hollywood salon Nine Zero One – a favourite hair hang-out for the likes of Vanessa Hudgens, Leona Lewis and Emma Roberts.
Her fans were pretty complimentary of her new look, but we have to admit, we weren't immediately convinced that green was the right colour choice for Hilary's skin tones.
Blues and greens are tricky shades to pull off in the world of hair – just ask Katy Perry – but now that Hilary's colour has faded and is revealing signs of blonde tones through the turquoise colour, we think it suits her so much better.
Will Hilary do a Kelly Osbourne though, and really own her new hair colour?
It's got definite keeper-potential if she goes down this slightly paler, ombre look – but then again, everyone loves a blonde...
