Bald, curly, mullet or Mohican, whether we like it or not our hair plays a crucial role in how we look.
But there's more to our crowning glory than meets the eye.
In Hairy Story Quentin Cooper goes on a quest to investigate the science behind our hair.
Why did we evolve to lose most of the fur that would have covered our ancestors bodies? Why might stem cell research pave the way for a cure for balding and what are top stylist, Nicky Clarke's secrets of a good hair day.
Join Quentin Cooper as he goes in pursuit of the hirsute.
