Good dye young

OH MY GOD I am someone that avidly will temporarily dye their hair for fun but jesus i have never had an experience where i had to shampoo my hair 10times just to stop the dark run off. Maybe its the colour i used (All in This Together) but everything was dyed and ruined because of its runoff. I literally had to stand and wash my hair until there was a light watery pink run off. Am i the only one thats had this issue? (I am a natural dirty blonde)
