Growing out natural hair, half bry orange, half dirty blonde...?

The reason your hair won't hold the color is because you have bleached it so many times that it is porous. To get it to hold some color, you need to go to Sally Beauty and buy protein filler. Get demi-permanent hair color while you are there. This is the least damaging (semi-permanent does contain ammonia). Apply the protein filler and then the demipermanent color. At first it will fade, but you have enough to treat your hair several times. You will probably have to apply the protein filler repeatedly for the color to stop fading, but eventually it will.
