Hi
You cannot go blonde, especially if you’re a brunette or have black hair, by using a box color kit. You’ll end up with orange hair. Instead you must bleach hair first if you plan to lighten your hair more than three shades. To bleach hair, especially if you’d like to be a medium or darker blonde, you need to go through a two-step process of bleaching first and coloring afterward.

Unless you’re truly experienced with applying color to your hair, you’ll definitely want to get an assistant to help you bleach hair. It’s difficult to apply bleaching formulas especially to the areas of your hair you can’t see, like the back of your head. In truth, if you want the best results, use a professional colorist instead of doing this on your own. They bleach hair every day, and are much more experienced at the process than you. You’re likely to be more satisfied with the results than if you do it yourself. However, for the people who don’t want to spend a lot of money on hair coloring, this is the standard method to bleach hair at home.

thanks
