Rated 4 out of 5 by from Seems to be working I was excited to try this - my aging hair has special needs. It's hard to find a product that "tames" the wiry grays without weighing down the rest. The only real problem I have is the overly perfumed scent. I am smell sensitive so I find it extremely off-putting.

Rated 5 out of 5 by from Good for kinky hair! I just received this product not too long and I've only used it twice but it is awesome! It makes your hair super soft and if you twist your hair and untwist it after it is dry, the twist out is defined :) I wish the bottle was a little bigger because it is pretty expensive. I deep conditioned my hair with Kiehl's Magic Elixir and some organic honey, then used this after and my hair is really soft. :)

Rated 5 out of 5 by from Soft hair This product really helps with my dry hair, which I get highlighted quite frequently. I love the shampoo and conditioner from the same line too. In conjunction these products have given me the best results I have seen in years. Highly recommended!

Rated 4 out of 5 by from Pleasantly Surprised I've used it a few times now and there is a noticeable change in my hair texture. I'm bi-racial with thick, course, dry hair and this product left my hair feeling smooth and looking shiny. Water is among the first ingredient which pays off the the fact that it's super moisturizing.

Rated 5 out of 5 by from Love this I use it to get tangles out of my curly hair. Works better than anything I have ever tried!

Rated 1 out of 5 by from Didn't work for me i have thin blonde hair that tuned straw like after a highlight/toner coloring process that went bad. It has taken 7 months to finally see results of getting back my shine and natural softness so I have tried many repairing treatments for hair. In the Kiehl's line the only thing that shows results fast for severe damage is the Olive Fruit Oil Deeply Repairative Hair Pak. I have plastic caps that I put on, wrap my head in a towel to keep in heat and let it sit for about an hour before rinsing out. Wow, it is amazing. Worth every penny. I also use the Amino Acid line daily and have also liked the Olive Fruit Oil line. I do not blow dry my hair and maybe that is why it didn't do anything. But this leave in treatment for me personally was a colossal waste of money.

Rated 5 out of 5 by from Best Product This is the BEST product I have ever used yet !! I have been searching for quite sometime for a product that does this great of a job with such minimal amounts. The texture is smooth and dissipates quickly into the hair with a nice fragrance.

Rated 3 out of 5 by from Great in principle I absolutely love the way this makes my hair look and keeps it hydrated. I have wavy and very dry/brittle hair and this stuff is lovely for everyday use. However, I was quite disappointed when I looked at the ingredients - I will not continue using this product because of the dimethicone and polyquats it contains, which are harmful to the environment, and also the dimethicone is not great for hair in the long run. Wish the chemicals that Kiehls uses were better!

Rated 1 out of 5 by from Not worth it I bought this product because my hair got quite dry this winter. It is naturally wavy with a tendency to frizz, and I have it colored every month. I'm in my 60s and have used an after-shampoo over-the-counter oil with vitamin E for years that was excellent but is no longer on the market. So I found this online. $25. Not worth 25 cents. Smell is ok but does nothing for my hair. Hugely disappointed.

Rated 5 out of 5 by from Coarse, dry hair from coloring? Give this a try. Context - I color my hair and wear it fairly short. I love the way my hair looks, feels and behaves after using his product. A small amount gives very nice gloss. Leaves hair clean to the touch- I don't feel the product - just healthy, manageable hair. Been searching for a good leave-in product for some time - one requirement is that I want to use only one product. This is my keeper.

Rated 1 out of 5 by from Sad purchase. This was part of my first 3 part order from Kiehl’s. I have dry, fine, wavy, highlighted hair. What a huge disappointment. The bottle is TINY. Leave on has the texture of water. I just got my bangs trimmed and my hairdresser said my hair was MORE dry since I started using this product 01/05/19. This is a huge waste of your money!

Rated 5 out of 5 by from The best things come in small sizes I can't believe I finally found a great leave in conditioner for my hair. I have black long wavy hair and this product is just perfect! I love it!! I use it every 2 days after using Damage repairing and rehydrating shampoo and conditioner. It leaves my hair so smooth, shiny and healthy looking. Oh, and also smells delicious.

Rated 1 out of 5 by from Disappointed The fragrance is overwhelming! This product leaves my hair dry to the point of having static cling and my hair feels straw like. I used to order Kiehls products because of my sensitivity to perfumes and have been disappointed in use of strong fragrance. Now I only buy 2 products for my skin and use Aveda instead.

Rated 5 out of 5 by from Keeps hair soft; smells great This leave-in treatments is excellent for keeping hair moisturized throughout the day. It's not sticky or oily like other kinds of leave-in products. I use it in the morning before applying styling product into my hair to keep my hair soft and light. Also a bonus that this stuff smells great.

Rated 5 out of 5 by from Fabulous!! I have very fine hair and frequently heat style so it tends to be brittle. My hair also tangles very easily not much how much conditioner I use but this product works like a miracle for my tangly hair. I absolutely love it and will continue to buy. It also does not weigh down by hair at all.

Rated 2 out of 5 by from Nope Waist length, dry, curly, thick, color-treated hair. Needed at least five pumps every time, making it quite expensive. It did not work the way it was advertised as working...no re-hydration, no, repair, no noticeable affect beyond detangling.

Rated 1 out of 5 by from Left my hair sticky Tried it a few times, applied smaller quantities too, but still left my hair sticky. I’ve been using the oil and it’s been great, so I thought I’d give this one a try but was very disappointed (for the first time with Kiehls products)

Rated 5 out of 5 by from Go-to Hair Product This is one of my all-time favorite products ever. It does an excellent job of hydrating and smoothing out my hair. I gently brush it through my hair after a shower and after air drying, it leaves my hair naturally wavy and shiny.

Rated 5 out of 5 by from WONDERFUL! The best hydration and hair conditioning styling product II have ever use!!! It leaves hair moisture, healthy, and not sticky at all! I USE THIS EVERY DAY AND WILL NEVER CHANGE!
Date published: 2020-02-17
Rated 5 out of 5 by from Smells great and moisturizes hair I use one pump of this before I style my hair, and it keeps my hair nicely moisturized for the rest of the day. Smells great too. The little bottle actually goes a long way.

Rated 3 out of 5 by from Love this product Love this product I use it instead of iron my hair. I just put it threw the ends and then put it up in a bun for an hour or so let it down and I have heat less curls!
