John frieda sheer blonde go blonder?

I have used both of these products and john frieda made my hair go limp and lifeless it also added dull copper tones to the blonde and i had to get it re-dyed and sun-in does work but don't use a lot as mine went a coppery colour again. being honest it is better to get it professionally done as you are guaranteed good results and it won't mess up! hope i helped good luck :)
