You can get it dyed and cut all the same day.
As a general standard, four to six weeks is a proper amount of time to wait before re-dying your hair. Your hair also can be damaged by dying too often. Many professionals recommend a timeframe of eight to twelve weeks, if you are constantly dying your hair.
That same day.
A couple weeks. Dying your hair darker is not nearly as big of a deal as lifting color-as with blonde dyes, etc.
at least 2 days.
well i would say about 7 months but it depends on what product you use or how bad it is
Since he was 12
At least 3 days but just to be on the safe side I would wait 6-7 days
approximately 3 days. i washed it a day after and it went all streaky and now its a disaster :S
