How to get an even hair color?

My natural hair color is dark brown. I have been buying colors like dark golden brown or medium golden brown so I could have some different highlights in my hair so it just isn't all one shade. My hair comes out ok except for the roots or sometimes...

around the crown area they are always a lighter shade. I always seem to have to buy the Clariol root touchup dark brown to get it to match or blend better with my hair. What can I do to keep this from happening? Am I just stuck with buying dark brown haircolor so I don't have this problem?

no. when you dye/ highlight your hair a LIGHTER color, the roots ALWAYS change much more quickly. you're supposed to put the dye on the length of your hair first, and for example the box said to leave the dye in for 30 minutes. well when 15 minutes have past, THEN you put the rest of the dye onto your roots, and wait the remainder of the full time. just wait half of the full estimated time the instructions suggests before you put the dye directly on the roots.

Avoide putting the dye on your roots. My hairstyling teacher always taught me that. The colour will work its way up and blend in on its own. And to avoid this problem, try and stick to one colour so you don't have different shades through your hair.
