I recently dyed my hair and it came out a LOT more luminous Purple than the box suggested. I panic dyed over the top more near my natural colour. Problem is every time my hair gets wet, the original purple runs colour everywhere! Both dyes were permanent ones. I went to work with my hair wet this morning. Came home and noticed my shirt was purple from where my hair has been. I must have washed and rinsed my hair ten times since the purple dye. Why is purple coming out? I’m supposed to go swimming tomorrow. How can I stop the dye running?!
