We've all heard about the Olympic diving pool turning green - but what about Ryan Lochte's recently bleached hair?!
The American swimmer was snapped with his gold medal after winning the men's 4×200-metre freestyle relay with his team mates Michael Phelps, Francis Haas and Conor Dwyer - but something was amiss.
This is him looking all excited about his new 'do' before heading to Rio.

And this is him now, post-chlorine swim, modelling an unmistakably green hue on his head.

People can't believe no-one warned him bleach and chlorine do NOT mix well together.
Why did Ryan Lochte dye his hair platinum blonde RIGHT before Rio?Does he not know the chlorine will turn it green pic.twitter.com/bImwAAfvWZ

Y'all Ryan Lochte lightened his hair before the Olympics and now it's green I can't breathe hello chlorine ?

I don't think @RyanLochte realizes what chlorine does to bleach blonde hair. Get a good purple toning shampoo sweetie! ?

It's kinda growing on some people, though.
