My hair is pretty much like a chocolate brown and I want to dye it a darker brown but not permenently. What is the best temporary dye I can use and it is ont going to damage my hair is it? I am okay if it never washes out completely because it will still be brown I guess right?

Heyy. L'oreal casting crème gloss is a good semi-perminant dye. Be careful how many times you dye it because I dyed mine a few times with sem-perminant dye thinking it would wash out eventually but it didn't. One dye over should last about 25 washes..
Goood luck =]
