If I bleach my already colored hair will the color go away?

Bleaching already colored hair can lighten or alter the existing color, but it may not completely remove it. The results depend on the type of dye used, the original hair color, and the bleach strength. Often, the underlying tones may become more pronounced, leading to unexpected results. It's advisable to do a strand test first to see how your hair reacts before applying bleach to the entire head.
