It's not just us non-celebrity folk that don't have time — or, erm, simply forget — to get our roots dyed. In an interview with People on the SAG Awards red carpet, Charlize Theron confessed she couldn't fit in a salon appointment, so her hairstylist, Adir Abergel, improvised by adding a Tiffany & Co necklace along her centre part. Now, we might not be adding real diamonds to our roots the next time we need a touch-up, but this is definitely a hair concept we can get on board with.
