Rated 1 out of 5 by from LOVE THIS! Reduced styling time by 75%! I love this product. I bought it on a whim at the airport during a trip to Europe in very muggy weather and it was a god send. I have textured, wavy (natural), below shoulder-length hair that can be frizzy and unruly. It took me a while to figure out how liberally to use this, but once I got it right (4-5 pumps on damp hair), it transformed my hair to smooth, manageable, silky, etc, etc.... can't say enough good things! I previously used Moroccan Oil and Kerastase products but found they left too much build up. Now I air dry a bit, blow out the front pieces and get out of the door with just 10 minutes on my hair styling time, compared to 30-40 minutes before.

Rated 4 out of 5 by from Smells Like Cotton Candy I love this product. I went into Kiehl's looking for a particular product but ended up leaving with this Leave-in Concentrate instead. I love using leave-in products as much as possible because I usually have my hair up during the work week. So, I figure, why not apply a product that will condition my hair while it's up? This concentrate feels silky and smells like cotton candy! My hair always feels great after application and, when I blow-dry and style my hair, it feels smooth and has a nice shine. I'd recommend giving it a try.

Rated 1 out of 5 by from very disappointed With humidity, my hair gets frizzy. When I found the Deeply Restorative Smoothing Hair Oil Concentrate several years ago, I was relieved - finally my search was over - almost regardless of the weather, my hair looked good - no frizz! This product doesn't work for me at all. Kiehls - please, bring back the Deeply Restorative Smoothing Hair Oil Concentrate.

Rated 1 out of 5 by from Very Disappointed I was so excited to try this product, but I'm sorry to say that it did not deliver. I don't know what they put in the bottle, but it has the opposite effect of what it says! My hair was more dry and frizzy after using it! I've tried it 3 or 4 times -- when my hair was wet, when it was dry, with the shampoo and conditioner in the same series, and with my regular shampoo and conditioner. It didn't work in any of these ways! I'm going to have to send it back because it really is just surprisingly bad for my hair and $25 is a lot to just throw away, The shampoo and conditioner in the same series are okay, but not great. I'd say of all the items in the series, the shampoo is best. You can tell it's moisturizing when you use it. The conditioner is just so-so in terms of delivering what it promises, and this leave-in concentrate is just crazy bad. What is in this bottle??

Rated 1 out of 5 by from Bring back Deeply Restorative Smoothing Hair Oil Concentrate PLEASE - PLEASE - PLEASE bring back the Deeply Restorative Smoothing Hair Oil Concentrate. It's the only product I've ever found that eliminated the frizz and made my hair smooth. The smoothing oil-infused leave-in only made my hair dry and frizzy.

Rated 5 out of 5 by from frigging awesome My hair is bleached and dyed, and this stuff makes it so soft and natural feeling. I saw results right away, and like someone mentioned in another review, it reduced my styling time by 75%. It smells so good, I get compliments everyday- its like a smoky musk in a tropical sunset. My only critique is the quantity you get for the price. Even though I only need to use a few drops a day, the size of the bottle kind of shocked me when I got it.

Rated 1 out of 5 by from Very disappointed I don't normally post reviews but in this instance I feel like I must. This product was the replacement for the Deeply Restorative Smoothing Hair Oil Concentrate. Many people complained that the Deeply Restorative was too greasy and a little bit went a long way. That too much was sprayed out of the bottle when used. I disagreed. Every product must be used the way it is intended and nothing will be everything to everyone. I have very thick frizzy hair and the Deeply Restorative was a godsend. I could almost use it alone as a styling product. This replacement is basically worthless. I don't know who this current incarnation of concentrate is for. Perhaps for those with very thin hair who complained before? Given how effective the previous incarnation was I am shocked by this one. It is as if I put nothing in my hair. There is a marked difference. My hair is thicker, puffier and much more unwieldy. Just in time for the humidity of NYC summer! I've had to scour the internet to find a store that has leftovers of the previous product until I can find something else. Kiehl's should have kept the previous, changed the applicator and introduced a milder alternative for others. Instead the old baby with the bathwater approach. At this price, for a tiny bottle that does nothing, I would never recommend this to anyone. It smells pretty good but that is more subjective. What matters is if a product works. This doesn't.

Rated 5 out of 5 by from BEST HAIR PRODUCT EVER!!!!! I have dry, damaged hair from hair coloring and heat styling for almost 30 years... this stuff is MAGIC and makes my hair feel brand new again, VIRGIN HAIR!!!!! SERIOUSLY!!! Yes, it is a little pricey, but a little goes a LONG WAY, you do not need to use more than a pump or 2 to get the job done. I have long hair and 2 pumps is all I need! I received samples previously and hesitated to spend the money but am so glad I finally gave in! I will never stop using this product!! PLEASE KIEHL's do not ever discontinue this!!!! Please keep this in your product line forever!!!! Thank you thank you for giving me back my "virgin hair"!!!! Did I mention, the SMELL IS AAAAAMAZING!!!!!!!!!
