How often should we really be showering?

Some people claim you should wash your hair every day; others say that letting it get greasy will “train” your tresses to stay oil-free throughout the week.

The reality is a little simpler, though. Not only has the “oil training” theory been debunked, but it turns out most of us don’t need to commit to an “everything shower” daily – instead, it seems, the best time to whip out your shampoo is when your hair looks and feels like it needs it.

So what about showering – a habit I’m adamant needs to be done at least once a day, despite not having the cold, hard evidence........
