Review title is Pretty good glaze [SEP] The first bottles I used had unpleasant odor, and the glaze was dull, but the latest bottles of glaze I recently received smell much nicer. The glaze lasts a couple of days, then I have to wash hair again, because it makes my hair look a tad oily. I still like the product. Just do not use too much at a time, and do leave on for 2-3 minutes before rinsing. I have very short hair(pixie cut), and color my hair platinum. Then I allow the color to grow out some, about a month, and it blends well with the roots of my graying brunette hair color. The glaze gives my hair a little lift, also, at least for a couple of days.
