Dyed Hair and StreaksQ: I just dyed my hair. How long do I wait until I can add streaks to it?
A: This depends on the condition of your hair and what kind of color process you used. I generally like to wait at least a week between performing a high-lift color service and adding highlights to the hair. But this is because the high-lift color can leave the hair more porous and more susceptible to damage from further lightening.
However, if you do use a deposit-only color with no lifting action, you can usually do the lifting-action highlighting in the same day if you want. Of course, all of this assumes that your hair is in good condition to begin with and that doing the multiple services won't damage the hair too severely.
ALWAYS, perform a strand test on the hair before doing any high-lift color service or highlighting service on previously lightened hair. Not only will this allow you to learn how much time the processing will take to get the results you want, but it will allow you to avoid losing your hair to severe chemical damage.
