The days are getting shorter and, it seems, so is everyone's hair. Thanks to celebrities like Rihanna and Jessica Chastain, a chic bob is officially the haircut of the summer.

But they aren't the only ones in on the trend. Other musicians, actresses, models, and teen activists are all giving the short hairdo a chance this summer, ranging from the near-shoulder-length lob, as in the case of Margot Robbie, to almost-pixie, as seen on Alicia Keys. And who can blame them for shearing some extra length? They say three's a trend but 14 makes it a movement, and these 14 celebrities provide the perfect blueprint for anyone thinking of chopping their hair into a bob or lob before autumn rolls around. Why bother sweating through the dog days of summer, when you can just cut your hair off and give your neck a break?
