Strand test Lied/Rip Off

I did a strand test on my daughters hair & it turned it a light strawberry blonde. Being no stranger to highlighting hair/coloring hair I thought with the heat from the plastic cap it may make it a bit lighter. Her hair turned blonde in front & red in the back. Not even strawberry blonde like the strand test showed. Her hair had been color treated almost a year ago to a medium brown. It tells “not recommended for color treated or gray hair” on the instructions in small print you should put this on the box not on the instructions,after the box has been opened & you can’t return it !! Loreal has this info on the BOX. Don’t bother asking me to call your lame help line. I already did & I was told to take her to a salon which is what I should have done in the first place instead of using your products. I won’t be buying from Clairol again you just lost a long time customer! I also had to tell her hair color is medium auburn,because calico wasn’t an option.
