Don’t wash it!

The Hollywood
actress says she’s so devoted to her hairdresser Serge Normant that
after a trip to his salon she refused to wash her hair for up to two
weeks.

“One of the tricks I’ve learned over the years is that I can
milk a great style to the last possible second. Honestly, after he does my hair, I won’t do anything to it for - wait
for it - two weeks. My hair doesn’t get greasy very fast, so I can go a
good ten days without washing it.”
