Another misconception about hair bleaching is achieving that Daenerys Targaryen mane with bleach alone. That's not so, particularly for darker shades. Black hair, for example, is actually made with red and yellow pigments — so when you bleach it, these pigments will fade, leaving your hair red, orange, or yellow. To remove this brassy color, you've got to tone it with a purple shampoo and a toner.
Note that there are different toners for different shades. If you get the lightest one and use it on your orange hair, it might not work. Again, research and manage your expectations to avoid disappointments and damages.
