I sampled this a while ago in a box and have finally purchased it. I went pretty platinum blonde from my naturally dark brown hair about a little over a year ago, and combatting brassiness has been tough with my hard well water. I've mostly stuck to purple shampoos, as most purple conditioners aren't as pigmented, and the shampoos I've tried so far are too drying on my already dry processed hair. This conditioner is pigmented like a purple shampoo but is much less drying. It brightened up my blonde in one use. My dad, who took a month to notice I cut 5 inches off my hair, commented that my hair looked blonder the last I saw him. If he noticed, then this stuff definitely works. The bottle is also way bigger than I expected, and I haven't had any issues with the pump yet after several uses, so hopefully that stays in tact.
