Burgandy back to ash blonde/brown?

Don`t srip the hair; it will destroy the condition of your hair. Since you already have three inches of roots, I would recommend just putting highlights in your natural color over the current color. Don`t try dying it darker, though. Dark dyes put on light hair tend to really stick. Since the dyes were semi-permanent, the hair should gradually become less red as you wash it, especially if you use a clarifying shampoo such as Neutrogena or Bumble & Bumble. Dying alone won`t work. When you put a dye over a darker color, the hair won`t get lighter; it will only get darker. The only way to get the hair lighter is to use bleach. If you do highlighting, it isn`t as damaging because the bleach is on all the hair. So that`s what I would recommend. In the future, if you want to change your hair color, always go lighter than your natural color never darker. I learned this the hard way as well. Dark even semi-permanent colors are hard to get out of light hair. If you color your hair and it`s too light, it`s relatively simple to dye it back to brown.
