Those who cut everything
Many have gone to the short haircut this year.
Léa Seydoux, Stéphanie de Monaco or Demi Lovato have all fallen for a pixie cut that completely reveals their face.
Even Jessica Alba and Selena Gomez have given up their lengths by opting for the trendy short bob of the moment, the "bob".
More radical, Iris Law, the daughter of Jude Law shaved her head for her very first role in a series.
In video, what haircut to change your head?
Bold colorings
The stars have shown us all the colors this year.
There are those who have gone from brown to blonde (like Maisie Williams and Kate Mara), or the other way around (like Billie Eilish and Katy Perry).
Those who have assumed their white or gray hair in the limelight like Andie MacDowell, Kristin Scott Thomas and Sarah Jessica Parker.
Others dared more daring colorations like Hilary Duff and her neon blue look, Shakira and her flash red or Jennifer Lopez and her pastel pink hair, which set the canvas on fire.
