I love the look of black hair. My hair is dark brown now but I think deepening it to a black would be very striking. Thing is, my hair is very healthy (bc I never color it) and I would like to keep it that way. Is there something that will just wash out after a few weeks, avoiding roots? My hair grows ridiculously fast and I can't afford salon upkeep. My hair is also very long and I wouldn't want to chop it off should I wish to go back to brown. It seems like I had seen something by John Frieda a while back...though I can't remember what it's called now. I do remember that at the time I think the darkest color was what I already had. I'd appreciate any advice!
