This is my first time trying Revicare products. I’ve used this purple shampoo/conditioner a couple times and it seems to be doing it’s job. I didn’t have a lot of brassiness to begin with so there wasn’t a noticeable difference. I got this more to prevent any from happening. I can say I like the shampoo and conditioner as it left my hair clean and soft. I didn’t notice anything I didn’t like about it other than it is very very lightly scented and I prefer a strong scent. So for those of you that this is an important factor, then this is the shampoo/conditioner for you. These were shipped with the bottles very tightly wrapped in a plastic so that if these got opened during shipment the leaks would be contained within – 5 stars for shipping!
