depends on the type job!
I actully am not suposed to have "unnatural" colored hair at my job but they have not said anything but once (one of the times I did it blue) I guess they just desided to give up lol I wore alot of BRIGHT hair falls right after they told me re dye it ... they couldn't say anything since there was nothing in the dress code about wearing fake hair lol
of course the shock of it has worn off since I been there 4 years now and tend to push the dress code whenever I can ...says nothing in there about white lipstick or red eyeliner... or leather/chain jewelry and of course I dare someone to say somthing (other then the occasional associate who tells me I am going to hell )
