The jury's out about whether it's actually healthier to wash your hair everyday or not. Everyday stimulates the scalp and the hair follicles which is good for growth, but over-washing can make dry hair drier and greasy hair even more oily.

Yesterday, a good friend of mine confessed that she hasn't washed her hair for eight days now. Today is day nine and counting... Her dry, wavy hair actually looks great, and surprisingly isn't greasy at all. She did admit she'd used dry shampoo on day seven – but only the once. Helena Christensen, who always looks beautiful, often talks about how she tries not to wash her hair that often.

At the other end of the scale, I know girls who wash their hair twice a day, and there's still a certain stigma in admitting you don't wash your hair every single day. My friend, for example, practically begged me to keep her anonymous! Honey, you know who you are...

So do tell - how often do you really lather up?
