They have so many different selections, plus the suppliers that we buy it from don't sell it anymore. They had it on clearance and they just dont sell it. I guess people dont use it that much. The ARTEC that you are talking about is just like Biolage's stuff and Redken's that deposits color. Its not as good as actually going back to put color in your hair if you want good results or if you are gray. (gray takes longer to deposit color). You could just use shampoo meant especially for people who have color. Try using Paul Mitchell's Color Care line. I use it and I have Highlights, but I got them by using bleach which is totally different from color but can still fade and get dull. I use the shampoo and its pretty good depending on your hair type and condition. My mom is a hair color specialist and is pretty good when it comes to doing hair.
