Is your bathrobe giving you skin irritation? Experts say you probably aren't washing it often enough and advise this surprising frequency

There are few things cozier than slipping on a fluffy bathrobe after bathing. You wouldn’t be alone in thinking that putting one over your freshly laundered pajamas, or straight on after bathing, means these coverups generally stay quite clean.

However, dermatologists and laundry experts warn bathrobes are more disgusting than you think, gathering dead skin cells and oils. And, how often you should wash your bathroom comes down how you use it (and how often), with the rule of thumb being, somewhat surprisingly, after every four wears.
