Find a semipermanent dye to apply to the dyed part to get it closer to your color--try a drabber ashy color to take out the red. When you have enough roots try having the hairdresser add highlights to tie in the colors and keep up the drabber color. The condition of the dyed part won't be wonderful, but the damage is already done.
Concentrate on keeping the new growth healthy. Try buying shampoos and conditioners for damaged, colored hair. They do work.
And get the dyed part cut off regularly. You'll see you far you have to go and it's not so bad. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
