Redken Extreme Anti-Snap is a great leave in conditioner. I bought it on a whim without reading any reviews because I needed a leave-in conditioner for use after shampooing. Since I highlight and blow-dry my hair, I felt my hair needed something extra to keep it in great shape. Redken Extreme Anti-Snap comes in a pump bottle instead of a spray-on. It initially surprised me because it's fairly thick like a normal conditioner would be. I was worried that it would weight my hair down because of the thickness. Instead, I'm happy to note that there wasn't a difference in my hair volume after use. I think that since it is so thick it is meant to be used on fairly damaged, over-processed hair-if your hair is relatively healthy, it might weigh it down. My hair definitely feels and looks healthier when I use this. I notice less split-ends and less breakage. I even notice less frizz on the days I use it. I will definitely keep using it.
