Is really good ! redken are the best product. i recommend this I have been battling extremely dry, brittle split-ends for as long as I can remember and this leave-in treatment is amazing. I use it at night after my shower and put a generous amount on my hair. Honestly, I use like 3-4 pumps of this stuff and just saturate my hair after I comb out the tangles. I don't use it on the roots, just from the middle down to the ends- focusing most of the product on my ends 'cause they're the driest. I absolutely LOVE this leave-in conditioner! In the morning, my hair is soft and my ends aren't dry at all. And it's not weighed down or anything either so styling is a breeze.
