Why won't my black hair extentions dye the color that i want?

I bought my hair extentions from sallys, and i wanted to dye them to my natural hair color. There black hair extentions but my hair is black too but its blackish brownish (im asian). i dyed it twice close to my natural hair color and it didn't work. I want to dye it again but i don't know what to do with it anymore. Should i just dye my hair black?





Plus my hair extentions are dyeable.Why won't my black hair extentions dye the color that i want?
I honestly have no idea, go back to Sally's and tell them what's wrong and they'll give you you're money back or new onesWhy won't my black hair extentions dye the color that i want?
I don't know anything about extensions but... dying black a dark color is like... dying something white white.





Try getting different extensions, some lighter ones, and then dye them.
Try taking them to where you bought them and asking them about it.
