This is an excellent leave-in product. The smell is nice, but most importantly, it really does leave my hair a lot less frizzy. I used it on towel dried hair out of the shower, and let my hair air dry, and it looked really good afterwards -- healthy! I can also cop to using it on a very rushed morning when I didn't have time to wash my dirty hair. A few light spritzes of this, and I didn't look quite as raggedy (I don't know if that's really one of the intended uses... but it works!). I first came to know this product because a stylist used it one time, and I'm really glad, because it's phenomenal.
