Was really disappointed with this color!

I have recently purchased and used Sparks Hair Dye in a bright pink color, I have previously lightened hair that normally retains pigment very well. The packaging and the quality of the dye seemed very nice, everything went well until it came time to rinse the dye. I followed the instructions fully and there was the very slightest amount of pigment left on my hair from the dye. Very disappointing, I had high hopes for this product!
