We reckon Scarlett's got more hairstyles under her belt than birthdays (that's 29 as of today, btw). So, in celebration of our hair-oine's big day, we've created the mother of all gifs: a chronological hair-story of Scarlett Johansson. From the blonde mullet (that was a brave move, wasn't it?) to a cascade of ginger curls, this lady's done it all. Have a good one, Scar-Jo! XOXO.
