I've been coloring myself for years and years (can't afford salon as much as I'd rather). A couple years ago I did Ion level 6 either rr or rv, can't remember at the moment with 10 developer. Then I put Special Effects reds over it. Since then I use the same permanent for the roots only, then Special Effects all over. When fresh and for about 3 weeks or so it looks like pickled beets

Now I'd like a change. I don't have the time to do the Special Effects part and I want a really intense red. I have 3 or 4 weeks of growth. I'm thinking of using L'Oreal Majirel, a level 6 red. Any advice for making this switch? Especially the roots? I wonder if I should do the Ion on the roots this weekend then the Majirel all over next weekend? I wonder if I need to strip the color first?

Having done my own hair for so long I realize all results good or bad are "on my own head" and won't blame anyone if it doesn't turn out ok.
