Collecting hair

I have been collecting my hair that fell out for over a year. On every different location I have been I created a new ball of hair. All of them have different sizes. The hairball of the city I live has the biggest size, because I have stayed here most of the time. Some of my hairball collecting locations are: Amsterdam, Delft, Kolkata, New York, Berlin, Istanbul, Athens, Ghent, Venice, Paris, Lisbon and Marrakech.
