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 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
