* Bleached hair has no pigment: Bleaching removes all natural pigment from the hair, leaving it a blank canvas.
* Home dyes work on existing pigment: Most home dyes work by depositing color onto existing pigment. Since bleached hair has no pigment, the dye won't have anything to grab onto.
What might happen instead:
* The dye may not take at all: You could end up with a pale yellow or white, depending on the bleach level.
* The dye may take unevenly: This is especially likely if your bleach job wasn't completely even.
* The dye might turn out a different shade than expected: Even if some pigment remains, bleached hair can react differently to dyes.
What to do if you want ginger hair:
* See a professional: A stylist can assess your hair and advise on the best way to achieve your desired color. They can use professional-grade color that is specifically designed for bleached hair.
* Consider a toner: If you want a subtle ginger tint, a toner can be used on bleached hair to achieve a temporary color.
Important Note: Always follow the instructions on your dye kit carefully, and perform a strand test before applying to your whole head. This will help you understand how the dye will react to your hair and prevent any unexpected results.
