Do you remember this photo? It was taken a week ago, when we visited a water park in Saigon. What we didn’t know at the time was that three days later the girls’ hair would turn green! After soaking their hair most of the day in what was obviously a pool full of strangely-chlorinated water, everything seemed normal. But then, two days later a sheen appeared on their hair, which turned into what looked like bright-green highlights on the third day. Well, it certainly made the Vietnamese stare a bit more than usual. After a week of living like this, we’ve finally found some better shampoo and conditioner that has sorted it out, and turned them back into blondes, but it’s a warning to anybody that fancies a cooling day in an Asian water park.
