Hi! I am 16 years old and I've had this thought in my head for a while that I want to dye my hair a couple of different "out there" colors. I have naturally dark brown hair with golden highlights in it. I want to add some like green, blue and purple streaks to my hair. Now, I don't want to do this all over my hair. I was just thinking of doing underneath my hair if that makes sense? I just want to do a section in the back of my hair underneath so that it is not that noticeable, but it's still there. I don't want them like highlights underneath, but dye a section of hair those actual colors. I don' t know, I was thinking about it and I would really like some advice on it before I do it. I would be getting it professionally done as well.
