I am all new to this.. but I'm wondering once I use the colorzap on my black hair and get into the brassy reddish color... do I dye my hair or do I have to bleach it... im trying to get a really light brown like blondish brown.. but I'm all new to this.. help would be appreciated... thanx*
By the way.what products should I buy at sallys..

My mom went to school for cosmetology. If you want to dye dark hair blonde (even if it is a darker blonde,) you will need to bleach it to strip the color away. Especially since it seems as though you use a lot of chemicals on your hair. The last thing you want is for any 2 or 3 of the chemicals to cause a mess. Why don't you get it done professionally?
