I am obsessed with Kristen Ess, and this conditioner is probably my absolute favorite product I've tried from her line. At first, I was hesitant to use it because I tend to have oily hair. However, I usually spray about 6-10 sprays into my hair when I get out of the shower, and it's never made my hair look goopie or greasy when it's dried. It smells beautiful, but it isn't a very strong scent and doesn't really stay with you all day. It also is probably the best detangler I've used! I have relatively long hair, so detangling is a must for me and I love how effective this is both immediately after I shower, and when I wake up with my hair dry and need to brush it (yes, this leaves my hair so soft and pretty even after sleeping on a wet head!). Finally, I've been using this product for about 7 months (since it first came out), and my ends have never looked better in my life! I hate getting my hair cut, and only cut it maybe 1-2 times a year, and before using this product I'd often have tons of split ends. However, it's been almost a year since I cut my hair last, and by this time it usually starts to look ratty but I barely have any split ends! I'm totally attributing this to the leave in conditioner because it's been the only product I've consistently used since my last haircut. Also, one bottle has lasted me this long, and I am always relatively generous with how much I use. I honestly don't think there is one con to this product-go out and buy it at Target! I promise you won't be disappointed.
