quick question

  1. my hair is naturally dirty blonde. 2 days ago i dyed it light brown, but the color is basically the same, so i want to dye it even darker. what would happen if i re-dye it tonight?
  2. I've re-dyed my hair plenty of times, although it does dry it out a lot, ur hair wont fall out like some believe lol, I've done a lot of fashion shows and have had them dye my hair for a show 3 times in one day and believe me, my hair isn't any thinner lol
