But first, I had to find it. I searched high and low, in every Duane Reade I passed in Manhattan, and couldn't find it. They all seemed to stock the Luminous Color Glaze Clear Shine, which does not impart any color "re-awakening" as the Luminous Color Glaze does, but I wanted the real deal. I may have gotten a bargain on my new hair color, but I was willing to spend $9.99 to keep it fresh.

Of course, I found the brunette version of Luminous Color Glaze at the CVS right around the corner from my apartment.

I've only used this once, today, and it's supposed to take three uses before a difference is apparent. You're also supposed to use it every time you wash your hair - a minimum of three times per week. (No sweat for me; while I usually try to go every other day between washes immediately following a color treatment, usually I have to shampoo daily or I just feel unclean.)
