Dyed hair dark w/ dyed blonde ends... need advice to make all one colour

[taylurx]

Hey there, I’m new to the website... I had my hair dyed like this over a year ago. I want to make my hair all one colour with box dye. (Would go professionally but obviously can’t at this time?)
My questions...
Will box dye even make it all one colour?
If not, would it be close to the same colour?

I am hoping a nice red-brown, a purple colour Or just dark brown.
Any suggestions of how others might go about this would be great.
Thank you in advance!

It's hard to know. Best thing to do will be to do a strand test, either on a hidden part of your hair (you can cut it off if you want) or with hair from your brush. Try out the dye you want to use on this hair. There's a good chance it'll be even with a red brown or purple because they're both forgiving.
