Hi Vanessa.
Thanks for your feedback. I'm sorry to hear that the colour is not what you expected. Unfortunately lightening dark tint colour is always a long process and usually takes a few visits to get it to where you want it. The good news is, there is always something we can do to get you closer your hair goals.
I will get Sarah to give you a call to discuss the best way to move forward with this.
Thank you again - Kevin
