Lasted 6 Months+ NO LIE
This dye stayed in my daughters lightened hair, and unlightened hair for more then 6 months! We had used MP but that was washing out in three days, hated it. The down side is I didnt wash it out very well because her skin turned pink and it was left on the sheetsfor about a week or so after but....... After that initial staining her hair stayed BRIGHT PINK for months! I could not believe it!  Even the unlightened parts of her hair stayed pink.
