Wondering how often you should wash your hair? Hairstylists say this is the correct amount

Some questions have neat, definitive answers, but how often should you wash your hair is not one of them. The answer to this age-old beauty query rests on a multitude of factors, from hair type and styling habits to lifestyle and even the area you live in.

And that's probably why so many of us get the calculation wrong. It's all very well having the best shampoo and conditioner for your hair type, but if you're not using them correctly, you can trigger anything from oily roots to rapid colour fade, dry ends or a sensitised scalp.
