I bought a small 75ml tube online, just to be able to test this. The Kiehl's Herbal Treatment Shampoo is my HG meanwhile so I was looking forward to test other products by this brand. The conditioner has, like most products, its pros and cons. Pros: The scent is heavenly: fresh, fruity, delicious. Once applied it's supposed to soak for two to three minutes. Afterwards the hair feels incredibly soft. A feeling no other conditioner has been able to provide so far and I've tested a few really good ones. After blow-drying (cold air only) my hair is really sleek & silky. No need for mousse or some other styling product. I do apply a little bit of the conditioner as a leave-in, though. About the cons: It contains silicones, yuck. I am aware of what silicones do to hair and that most of the silky and soft feeling is probably provided by them. I used to use cone-free conditioners for years up until now so I'm torn. I love how my hair feels yet I'm unhappy with applying silicones. Dilemma, no? And another let-down: It doesn't help with frizz. Humidity is my own personal enemy and as soon as there's a little air moisture, the sleek look is gone. Bummer. So I'm taking off one lippie for the silicones, but I can live with the frizz and I love the overall feeling of my hair. I'm fairly sure I'll buy a huge bottle once I'm done with my small one.
