gatinha321 - Hair Type: 2a I think I've gone through 3-4 bottles of BG Crystal Flash. I have brunette hair and have had no trouble using this. My highlights really stand out when I use this. This is a cream formula with pink mica flecks in it. As with any shine product, you don't want to overdo it. I just use on my ends and not my crown, or if I do, I just put what's left on my hands after runny it through my ends. There is a yummy grapefruit smell that lingers a little but I like it. It's uplifting. This was my favorite product of the Blonde Glam line. I was NOT impressed by the shampoo or conditioner at all.
