I just got my hair dyed.. and the lady messed it up, and won't fix it... HELP

Ok. Please explain in more detail. What happened?

I went through the same thing you did... I used PALMOLIVE LIQUID DISH SOAP as a shampoo for about a week with GARNIER FRUCTISE EXTRA MOISTURE CONDISTIONER... I would wash my hair let the SOAP sit for FIVE MINUTES then rinse... put CONDITIONER in (alot! ) and let it sit for TEN MINUTES... I would rinse it out and then put GARNIER FRUCTISE SLEEK AND SHINE HAIR SERUM in and COMB out with a FINE TOOTH COMB so it was distributed EVENLY... DO NOT BLOW DRY... do this for a WEEK and your hair will go from BLACK to LIGHT medium BROWN... fading drastically...
