My hair at best was a darker brown, no where near black.

I have wavy/curly hair that's medium/dark brown

This turned my pale brown hair dark brown with an ugly orange/red tint because it faded IMMEDIATELY

My hair was dark brown (probably a level 4 or 5) and the red still took

My hair was bleached to a dark blonde/light brown so the color came out more magenta/maroon but in the sun it appears more red

I am going from platinum blonde to dark brown

My hard is a dark brown with reddish highlights, and I set it on my hair with a tiny bit of kerotin infused conditioner for 2 hours

Sadly didn't work much on my dark brown

Beautiful color, the hair was bleached, regular hair is dark brown

I do recommend this color if your hair is not dark brown

my hair is level 3-5 (very dark brown in varying shades) and this dye, when applied on dry hair and left on overnight, dyed the stands a very pretty deep red

My hair isn't a dark brown at all

and I got dark brown
