Does loreal feria hair dye really contain metallic dyes in it? - feria hair dyes

I heard they were trying to read the ingredients on the back of the box, but you do not know what all of these ingredients have not really helped me lol ... In any case, I like the way it makes my hair feel that he did not feel after use for damage and given the color so beautiful .... In addition, dyes containing metal? if not, they are really bad for your hair?

* My mother works in a salon and this gives me a better color than I have in a room ... but I will not use it if it my hair bad ..
