I got my hair colored at a salon and I wanted a brown but I ended up with bright blond. How long should I wait to color it again?

Depending on how much of a hurry you are to get it back to the color you wanted, the normal wait time is a month, this way you don't have to damage your hair too much. You see every time you color your hair, it gets damaged. So if you haven't colored it much, and are in a hurry, 1 or 2 weeks from when you got it done will do. It's really up to you. But I caution you, it will be more damaging if you do it sooner. And if you do it sooner than later, skip washing your hair everyday, the natural oils in your hair protect the damaged hair. Also don't use your hair dryer everyday, this is also very damaging, limit it to 3-4 days a week. Hope this helps!

You an go back to the salon you received the service at and request they use a demi permanent hair color to get the color you wanted with little to no damage . I am a stylist and I use matrix color sync and have done this many times with great results. If they refuse let me know and I'll help you get it where you want it.
