Last year, I used those At-home care products to dye my hair to brown color. Moreover, even though I used the same one always it turned my hair color to red. Nevertheless, I have somehow gotten it back to how it was supposed to be. But there is still tint of red in it. Any idea how can I get it to dark ash blond? How can I get rid of slight tint of red color that is still in my brown hair color? Please only tell me about the ways that are effective and safe for my hair. I hope to hear soon from you guys out there. Thanks.
