I am looking for the longest lasting dye for unbleached hair. (medium blonde hair).
I would like it to be either purple, dark green, dark blue, teal or turquoise. (basically any mermaid colours).
Please tell me what you think! Many thanks!!! π
Semi-permanent bright colors tend to not stick to unbleached/natural hair. The hair cuticle needs to be "roughed up" to get it to stick. It is likely that it will just rinse out. As far as longest lasting, Pravana Vivids are supposed to last a while I believe - but since they do, I don't want to use them. I like changing colors. I have heard that Ion has some also.
