Oh girl! Never, never dye your hair!! Red hair is beautiful! It is different. Men love it because it is so different! I have red hair, my granddaughter has strawberry blonde hair--it's just beautiful~ no beautician can buy that color in a bottle!! Learn to look at it in a whole different light. Fall in love with it because the men sure will!! Lots of girls/women would love to have that color!! Red headed people usually have freckles too-that's a dead give a way for red hair. My granddaughter loves her freckles too--I told her they were Angel Kisses! Life is all in how you look at it! I say--Cheers to the Redheads!!
Try doing a semi permanent/30 day dye. Not a permanent. That will look awful growing out if you did a permanent. I think going from bright red to black will be too much of a drastic change. Maybe use the black dye to put black highlights in your hair. I think that would look awesome. I would love to do the opposite to my dark hair but it won't work. Be careful dying your hair too much. I messed up mine doing too many crazy colors in it. Good luck!
