First, take a deep breath. You didn’t do anything wrong. Blonde hair turning yellow is as natural as your favorite white t-shirt turning grey after too many washes.

The biggest culprit? Heat styling. That curling iron you love? It’s frying the color right out. And let’s not forget your trusty, cheap shampoo that smells like a piña colada—it’s probably doing more harm than good.
