@raphaela Hello, yes it is true Washing too often can do more harm than good. Washing your hair twice a week isn’t bad, besides avoiding washing every day. You can wash your hair every 2 to 3 days. Everyone's hair type is different you should do what suits you. Washing your hair two to three times a week with the right shampoo will not cause you to lose your hair. In fact, keeping your hair clean and removing products, oil, pollutants, and other buildups can actually improve your hair and scalp health.
