Let’s start with the obvious culprit: your shampoo. You know that stuff that smells like a tropical vacation and foams up like a cappuccino? It’s likely stripping your scalp’s natural oils. (I’m talking to you, sulfates.)
If you wash your hair every single day, you’re basically power-washing the protective barrier off your head. It feels clean for ten minutes, then the itchy desert returns. Switch to a sulfate-free shampoo or try a “co-wash” (conditioner-only wash) a few times a week—your scalp will send you a thank-you note.
