Since my hair is black, will it be the same color as the girl on the box? or will it be much darker and unnoticeable?Revlon 10 minute hair color kit?
If your hair is jet black naturally, it is going to be near impossible to get your hair that color without coloring it too many times and making it damaged. Your best chance will be to go to a salon and have them tell you if they think it is possible, let them do the color on it and if it works....then from then on you can use a box. I would leave the first try though up to a professional.
