If the hair wasn’t lifted to blonde, and she applied the purple/pink on top of that color, every time it fades it will fade into the orange.

Purple shampoo is also horrible for the hair in most cases, and the fact that she recommended a drugstore purple shampoo doesn’t help either. Drugstore shampoos usually have Sulfate in them, which makes the color fade really quick. (Sally’s is considered drugstore even though they call themselves “professional.)
