My favourite part of dry shampoo is that when I need a lot of it, it turns my roots completely grey (something age is also doing with alarming expediency) and I get to have a sneak at what I'll look like when I'm old, minus wrinkles, though neither of my parents really have them anyway, so I like to think it's pretty true to form.

And then I get all smug and want to high-five future husband, like I'll still have this ass in 30 years.
