Are you a natural blonde? Natural blonde hair (even if it's very light) will be much less porous than pre-lightened hair strands. For that reason, you'll want to choose very pigmented shades in mostly warm tones for best results. A lot of issues can be avoided with the right color and the right mix! For example: If you want to go dark blue and you have warm/yellow tones in your hair, you'll want to add in some darker purple to the mix to help offset a green result but ALWAYS do a strand test before coloring to ensure you'll be happy with the outcome!
