Almost black

I have been coloring my hair for years with excellent results. I usually used a Med. Warm Brown and had beautiful reddish highlights. Last spring, my husband talked me into having highlights (blond) added. I went to my salon and had this done. She used a cap and added much more than I wanted. Everyone loved it but me. We went on vacation to another state for 3 months and I took my "formula" with me. I went to a salon for a "touch up", but came out with an all-over blonde! It was kind of brassy looking so I used an Ash Blond (don't remember what product) and it toned it down. I lived with that for another 4 months and decided I wanted to go back to my reddish brown hair. I used a light reddish blond straight from the bottle (no developer) to get color back into my hair and then I used a combination of shampoo, hair color and developer and it turned out good, but not at the level I wanted (still a little too light). That was almost 2 weeks ago and today I used a Med. Warm Brown. I made the mistake of not doing the touch-up method--I applied it to all of my hair! UGH!!! You guessed it--nice reddish brown roots but with dark (almost black) on the outer portion. Can I use Color-Fix or should I try Dawn or Tide? I have Palmolive--will that work, too? I called Revlon and they suggested Dandruff shampoo. I used it today but it doesn't look any different. HELP!!

OK--this is what I did. After staying up 'til 1AM this morning reading all the horror stories on this forum and all the helpful information I decided I would try Dawn this morning in the shower. Nothing happened. It was still awful!!! I have always been VERY particular about my hair and decided I could NOT live with the color. I went to Curves and felt like everyone was looking at my hair---which they probably were! Remember, 2 months ago I had blonde hair when I started. After I left there I went straight to Sally's and talked to a very helpful girl. She agreed that ColorFix is the best corrector. She helped me pick out a new shade to reapply. I went home and told my husband it was "hair day" and then I disappeared in the bathroom. Well, ColorFix was so easy to use and the results were tremendous!!! I applied my new color to my roots first and waited about 10 minutes and quickly distributed it through the rest of my hair. I only left it on for a minute and then rinsed and conditioned with a great conditioner the girl at Sally's recommended. I can't tell you how great my hair looks!!! I now have a light reddish-brown close to what I was aiming for and I've gotten a couple compliments on it today!! I can't thank everyone enough here and at Sally's! No more going blonde for me. It's too pale for me. I need color around my face even though they say you should go lighter as you get older. Just as long as it's NOT black!! LOL Thanks again. :)
