What happens when you put blonde hair dye on very dark brown hair?
It turns orange! I did it in 10th grade & my mom made me go to school like that!
What will happen when you put blonde hair dye on very dark brown hair is that your hair coloration will probably lighten up. When your hair is bleached, it creates warm, or sometimes yellow-red, undertones. Check out http://science.howstuffworks.com/innovation/everyday-innovations/hair-coloring4.htm for more information.
You always have to reverse the process.. In order to get the correct color.. So you are going to have to bleach the dark color off before you put on the blonde.. Good luck
Don't do it.in the long run it will ruin your hair.
You will get orange hair, " Latina" has the correct process.^^^
your hair? or someone else's...
