Query: Horrible stuff

I bought this shampoo after my red started fading faster than usual; I wanted to rescue what color was left so I purchased this in the hope that i could salvage my color.Unfortunately, this shampoo left a sticky, nasty buildup that left my hair feeling completely damaged. It went completely limp, felt oily and literally sticky and dried out like I'd over bleached/processed my hair or something. I couldn't even run my fingers through my hair without it snagging on massive mats and knots in my usually stick straight and slippery hair:(After about a week of this mess I decided to give up on what was left of my color and use a baking soda and vinegar solution to strip the residue (whatever it was!) out of my hair. It took three days to work this stuff out of my hair and it's finally back to normal. Thankfully what was left of the color wasn't harmed after 'stripping' my hair with the BS/vinegar solution. That's the last time I ever use this shampoo!
