The truth is, there is no ‘one size fits all’ rule for people to follow about washing your hair. But Dr. Anthony Rossi, an assistant attending dermatologist at Memorial Sloan Kettering Cancer Center in New York City says that people need to give themselves a chance to have dirty hair and see how it goes. Maybe your scalp and hair won’t become instantly greasy after a day or two. Washing too often can dry or dull hair. The length between washes can depend on multiple things including hair type and style, how oily your scalp tends to get, age, and your activity levels. Dr. Rossi tells his clients to only wash once or twice a week, but definitely once if you have treated or bleached hair. Teenagers may need more washes due to access grease during those years, but on average MOST people don’t need to be using shampoo and conditioner everyday. No go take Dr. Rossi’s advice and see how long it takes your hair to actually get nasty.
