Help, please. My light ash brown (colored) hair is, when not dyed, an overall medium to light gray (not sure which, if you know what I mean. LOL).  It's EXTREMELY dry and limp.  I can pull it straight out on the sides, for fun and laughs, and it will remain there indefinitely.  I've used mostly Revlon Colorsilk in light ash brown (what my hair used to be) with minimal amount of self applied highlights on top.  I use this brand because someone told me it's very low in ammonia and not as drying.  I also use a box highlighter, also with no ammonia, and apply it after coloring.  Two things have happened over time:  The color fades quickly and it seems dryer than ever, no matter what color brand I use or whether it has ammonia, and the color looks "flat" without highlights.  What I'm wondering is if anyone can recommend a brand of light ash brown permanent color that actually helps hair, or at least lasts and gives shine. Same with a highlighter.  I have a Sally's a couple blocks away, but have never been there.  I don't have time for a salon and am going to an imporant event in one week that lasts two weeks. Thanks for hanging in there.
