You probably pulled too much hair through the cap or didn't secure it tight enough to stop the dye from seeping through the holes. The hair you pull through shouldn't be thicker than a strand of spaghetti, and you should avoid getting any dye on the cap. To fix your problem, color all your hair with a semi- or demipermanent dye close to your original color; look for the words natural, ash, or neutral on the box. The color will cover the orange streaks but still leave them lighter than the rest of your hair. The result: Subtler highlights than you originally wanted—but no more tiger stripes.
