Hair Dye Color & Developer Question!

You don't need a 30 volume peroxide unless you are really going light that is usually used to do a 2 process color, if you had picture though I could see what you are talking about better and help more. What you really should do is find a numbered color chart on line. Hair colors are thought of in levels and if I knew what level you are and what you were going for that would really help. Also a picture would show what undertones are going on. In most cases when going lighter people want to fight briness or red tones but not in all cases. Most people do have lots of red undertones. I don't want to tell you the wrong thing though and then you may want to go darker again and end up green.
