A comic once said "The true definition of a woman is someone who's hair is never quite right."
Thank God there are a bunch of physicists out there who are just as concerned with hair as women (and some male movie stars).
Raymond Goldstein of Cambridge University and his pals are looking at how the 100,000 strands of hair on the human head turn into a shapely ponytail.

The researchers looked at the properties of a single hair and came up with a "Rapunzel Number" (commenting that they "couldn't resist") based on the properties of density, curliness, elasticity and the eventual length of the ponytail.
They found out gravity makes a difference when it interacts with these properties (duh) and shapes how the ponytail hangs or puffs out.
All they really needed was a loo full of teenage girls who know more about the struggle and triumphs ponytail shape than any bunch of silly Brits with degrees in physics.
