1. Is it safe to dye my hair a light brown shade then the same evening highlight it blonde? Any tips?
  2. Are you doing it yourself or going to a salon? When I get mine done, at the salon they do it the same day. I don't know about doing it yourself. I would say wait a couple of days, just to be safe...:yes:
  3. First I would say what is your original color? I would also wait a day. Maybe even wash it one time? I haven't done my own hair in years so I'm sure a lot of the newer products have changed. I always like to play it safe though. Good luck, let us know how it came out.
