This is my favorite leave-in conditioning product that I have tried so far. It claims to have 25 benefits and I would believe that considering all of the great things it has done for me, and all of the benefits it offers including it's sulfate-free, paraben-free, and lightweight formula. I have used other products in the past that have claimed to reduce frizz but they never worked. I do not have frizzy hair but if its humid and I get out in the rain my hair is a mess..with this stuff my hair is so much more manageable in every different setting. This is a prestige product so that may turn some people off, but $36 at Ulta gets you a decent-sized bottle of this stuff. My first 13.5 oz bottle lasted me about 4 months? So it goes a long way. I use it every single day and it lasted that long...I am impressed. Also, Ulta will often have sales on REDKEN products where you buy two and get one free, so you can stock up on this stuff and save money. My main use for any leave-in conditioning product is the detangling factor. I like to minimize my getting-ready time as much as possible, so I like to spray a bunch of this in my hair after a shower and it makes the brush glide through my hair so easily. Also a God-send for use at the lake or beach.. so good.
