Well I've been coloring my hair a few yrs now dark brown/black so yesterday I decided to go back to my natural which is light brown.So I bleached my hair,roots came out bright orange, while the rest of my hair lightened up just a little bit.I applied color but don't like the results it came up too red so I want to go back to brown/black.Is it o.k if I color it again or should I wait a couple of days.I thought about using a demi/semi permanent but I know that in the end would have to dye my whole hair since they wash off.Any help would be greatly appreciated

I've dyed twice in one day before, to cover a mistake.  Not sure about more, though.  If I had to guess, I would say to wait a day or two to let the scalp oils build up, at least.  And a semi would definitely be safer than a permanent.
