How long does does dyed black hair take to fade?

I just dyed my hair black and I really like it but I fear it could fade into a dark brown color.How long does does dyed black hair take to fade?
if your natural hair color is dark brown, then it will absolutely go back in that color over time. i cellophaned my hair with a black color(my natural color is dark brown) about 6 months ago. i dont know if cellophane and dye is the same thing tho, but my hair was jet black after the process.





but now, the blackness of my hair faded just a little bit, and you can see its real color when it touches light. but when it doesnt, it still looks black. :)How long does does dyed black hair take to fade?
like 1 week





i dyed my hair black from dark brown 2 weeks ago and i used a good dye that cost me 拢7 and my hair's going brown at the ends already





though i tihnk this is due to straightening but i don't straighten a lot really.. :/
every one is different use a shampoo and conditioner for color treated hair , that will help ALOT
