Many of you were shocked when we reported that British cooking queen Nigella Lawson only washes her hair once a week.

But now it turns out Justin Timberlake is anti-shampoo, too!

He told Allure he washes his hair "once every 10 days or so" and that "it's more manageable with the natural oil."

We're shocked -- we had Timberlake pegged as a wash-and-go guy, and now it seems he's more of a don't-wash-and-go guy.

What do you think, Style-istas? Is it silly (or gross) for a guy to wait 10 days before shampooing? Do you forgive him because he's Justin Timberlake? Or does curly hair (even as short as Justin's) need all the help it can get, even if that means not washing it?
