Get 5 health regeneration from enemy damage in a row, without dying
You can certainly color your hair for 2 days in a row if you'd like. This isn't healthy but it shouldn't cause extensive damage either.
You may have some irritation if you are dying your hair two days in a row, especially if it is your first time actually dying your hair, i dye my hair often and i have never had a difficulty dying it twice in the same day, so you should be OK.
once a month
As many as you think your hair can stand, coloring your hair suck moisture from it, causing it to break, or fall out, so its really up to you the most I would go for is two, maybe three times in a day then wait about 2 weeks.
