Temporary, Semi, Demi, Permanent? What's the Difference?!
I know a lot of people are confused on the subject of what is temporary? Semi-permanent? Didn't even know there was such thing as a demi-permanent? So, temporary dyes are, well, temporary. Temporary in the sense that they are one time use. Temporary dyes are anything from spray ins, such as the photo on the right, colored gels (the kind that comes out during Halloween season), and rinses. Apply the temporary coloring right over your own hair color (without bleaching or anything). When you wash your hair, the color comes out. Temporary cannot lighten your hair. Semi-permanent Semi-permanent hair dyes are most likely the vibrants. Red, blues, orange, yellow, green, purple, teal, etc. Semi-permanents do not require a developer but they do require that your hair be bleached to show up vibrant. Take a white piece of paper and get a pink crayon, the color comes out pink. Take a black piece of paper and try to color it pink, and it doesn't show up. Same concept with your hair...
