Rated 2 out of 5 by from Horrible Travel Packaging for a Good Shampoo This review is of the 2.5 oz size since while I enjoy this product as an every day shampoo, the travel size product fails horribly. At first I thought it may be an anomaly that my Kiehls bottles frequently leaked on domestic business travel, but after recently returning from 8 weeks of international travel which included 10 separate days of flying, I can say with certainty the travel size Kiehls bottles are no good for checked baggage airline travel. With a shower kit housing more than a dozen shampoos, face washes, creams, etc. the only bottles that leaked any during my travels were my Kiehls Creme deCorpa lotion and my Kiehls travel size shampoo. I even tried pushing air out of the bottle before the trip to give it room to expand to no avail. The only thing that prevents getting the rest of your suitcase full of lotion and shampoo is to put the Kiehls bottles in plastic baggies. While that works if the baggie is big enough and sealed, you waste the product that escapes and have to spend time cleaning out the baggie to use it for the next flight. Not sure why Kiehls products leak when other high-end brands don't. Bottom line: the shampoo is great but don't waste your money on Kiehls expensive travel sized bottle; buy a cheap travel bottle and use that instead.

Rated 5 out of 5 by from Rich lather, nicely scented The lather is great and is telling me that my hair and scalp are getting the full cleaning treatment. The scent is very pleasant without being too strong -- just enough to remind you it's there. I rotate this shampoo with others, but I would use it daily.

Rated 5 out of 5 by from Must-have Shampoo This is the perfect cleansing shampoo! I don't use it every wash, but rather every few times to clean out all the grime (products, dry shampoo, and general build up). It leaves my hair feeling baby soft and smooth. It's also been extremely safe on my colored hair. Lasts a long time as long as you don't use it every day - only thing is that when I do use it I find that I have to use more than I do with other shampoos to get a decent lather worked up.

Rated 5 out of 5 by from Best Shampoo Ever! I started using this shampoo about a year ago. I was introduced to Kiehl's products through my gym membership. At first I did not think anything of it just that it smelled great. Over time I realized that my curls stayed intact, my frizzy hair was gone and my highlighted hair was shiny. I will never go back to using any other product.

Rated 5 out of 5 by from Love It I've been using the amino acid shampoo and conditioner for almost three months and I love it. It leaves my dry hair feeling healthy and manageable. PS I'm African-American with wavy/curly relaxed hair

Rated 5 out of 5 by from All Hair Types I Have never been so pleased with a product. As you can see my title is all hair types because I have finally found something that actually does work on African American hair. I had a problem with my hair shedding not anymore, this product leaves your hair nice and soft and very manageable you WILL NOT be disappointed. From now on this will be the only shampoo I will ever use that's how satisfied I am

Rated 4 out of 5 by from Neutrally good Does anyone else remember that this shampoo used to be darker in color and it smelled sweet and faintly of soda? Gone is the color and soda scent, leaving it a little too neutral. Nothing bad to say about it but I miss the old version.

Rated 5 out of 5 by from Love this! It is winter time and anything with humidity in it is freezing in these low temps. I chose products to keep humidity in - like this shampoo. It left my hair, which was drier than normal, in perfect condition! I received the sample product and didn't need to apply olive oil conditioner, which left my hair oily. After waiting for days, and re-washing, my hair is in per condition. As if we were not in winter!!!!! This is simply amazing! My advise: try using the product alone, without conditioner. If your hair is not normal, than re-wash with a light conditioner. Thank you Kiehl's for having another wonderful product.

Rated 5 out of 5 by from Works Like a Dream I had first gotten introduced to this line from a sample from maybe four or five years ago, tried it, loved it, and promptly forgotten it. But, having moved from CA to WI my showering habits quickly needed a re-vamp. The water here is hard, and my hair tangles like crazy. I couldn't afford to use to expensive salon brands because I am in grad school so money is tight. That being said, I was going through drugstore brands like water; the 5.89 'extreme treatment' conditioners and shampoo cleansers lasted a week in my hands. So Amino Acid Shampoo comes into my life. Yes, it is a cleanser (judging by the contents and label) so it works if you live in an area with hard water and your hair just feels like gunk. Yes, I do have to wash my hair everyday, but I have oily hair, and always will. Nothing is going to change that. (I am multi-racial, with thin, very long, wavy hair, but I have A LOT OF HAIR that tangles like mad). So it cleans well in extreme hard water, leaves my hair detangled, rinses easily (a blessing for those with long hair) smells great, is a bit pricey for someone who usually buys store brands, but works just as well as the more expensive top of the line salon brands. The bottom line is, if you are looking for a shampoo that works on a) tangles b) rinses easily c) oily hair d) thick or fine hair e) hard water build-up this stuff is for you. Sidenote: Both my husband and I use it, and he doesn't find the scent to be too 'girly'. He has thick, curly hair, and a flakey scalp and finds the shampoo to work just as well for him. That being said this shampoo isn't for everyone, we all have different hair-types, but if you have similar problems, this stuff is a lifesaver, even if you have to pay a bit more.

Rated 5 out of 5 by from The Best! I have been using this shampoo for twelve years; before it was popular Kiehl's left out the harsh detergents in this shampoo. The smell is dreamy and it leaves your hair incredibly soft!

Rated 5 out of 5 by from No frills thrills The Amino Acid Shampoo is the best shampoo I have every used, and I've tried too many. I used a sample at a hotel in New York City, and I haven't looked back since. This shampoo has a wonderful smell, excellent texture and leaves my hair (fine, with grey coming in) with body, few tangles and no residue. My hair has body and is easy to style. This product is "no frills" because the results speak for themselves. No hype necessary. I use the conditioner, too!

Rated 5 out of 5 by from Shiny! I got a sample of this and took it on a short trip. Great smell, great effect, and - a big surprise - great shine! Works fantastic for my coloured hair, and is a great prep for a deep conditioning treatment. I am going to let go of my expensive Kerastase shampoo and try this for the next couple of months...

Rated 5 out of 5 by from Worth every penny I don't think I'll ever use another shampoo. It's not too harsh on my hair and leaves it soft and clean. Doesn't strip it like some shampoos. I also love how it smells.

Rated 5 out of 5 by from Best shampoo so far! I really love this Amino Acid shampoo. It makes my hair soft and puffy, with a very warm scent of coconut. The price is a little bit high, but I will keep with it!

Rated 5 out of 5 by from Amazing Amino Acid Shampoo We had an incredibly long, cold, wet winter in the North East. With that in mind, I decided to grow my hair out longer than my traditional normal haircut. One of the things that I noticed with growing out my hair was the tendency of the longer hair to get frizzy or tangled after I washed it (before I combed it out). A friend suggested I try the Kiehl's Amino Acid shampoo to strengthen my hair as I grew it out. I forgot about it until I was walking past the store on 14th street and thought.. WHY NOT! 1) It SMELLS GREAT! I have sinus/allergy issues, so I have to be careful with new products. The smell does not cause my sinuses to get inflamed so that was the first good thing. 2) My hair FEELS so much more nourished and healthy. I have always gotten compliments on my hair, but NOW, I can feel it. I am not sure if that makes sense, but I feel like my hair looks and feels better. 3) As I have gotten older, my hair has gotten more fine in texture. This shampoo doesn't weigh it down. It still has bounce and volume and control. The Conditioner is so good that I only have to use it once a week. This will tell you how much I believe in this product... My mom had breast cancer a few years ago and after chemo her hair didn't come back as thick and full as before. She wasn't happy with anything she tried so I sent her the Amino Acid Shampoo. She can't say that it is helped with the thickness, but she too loves how her hair feels.

Rated 5 out of 5 by from I love this Shampoo I started with the samples, and I have to say that my hair looks fabulous after washing and conditioning with this product. My hair is so bouncy, soft, and smells great. I have very long thick hair.

Rated 1 out of 5 by from Dry tangled mess I got a free sample when I was getting my Avocado Fruit conditioner. I didn't care for the smell, the lack of lather, or the way it left my hair. It looked like a tangled heap of straw and even slathering it with the conditioner, I couldn't get a wide touch comb through it. I will not be using this again.

Rated 3 out of 5 by from Makes my hair soft but greasy the next day I have thick hair and this shampoo makes my hair really soft after using it with the conditioner and it smells great. However, the next day, my hair is greasy. I typically wash my hair every other day but I can't with this shampoo/conditioner. I need to wash my hair everyday. Although it smells great and leaves my hair very soft, I wouldn't buy it again.

Rated 5 out of 5 by from My Daily Shampoo This is the shampoo I use daily. It's able to produce a generous amount of foam but still be mild enough for daily use. I love how it leaves my hair shiny and soft. I also use Amino Acid Conditioner, which is the best silicone-free conditioner I've ever tried. However, I found residue builds up after a period of using this shampoo, so I guess it might be too mild to completely clean my scalp. I'm very picky about what is used on my hair but I know it's impossible to find a shampoo that is both mild enough to be used daily and strong enough to clean my scalp completely. Now I also use some other strong cleaning shampoo once a week to get the job done. Still, I love this shampoo and how it smells so I will buy it again.

Rated 3 out of 5 by from I wanted to love this product I was so excited when this finally came in the mail (it took almost a week just to ship). I love the scent, its a light coconut like others have said. It makes my hair feel clean but without conditioner it is in knots. Granted, I do have highlighted hair. I must use a conditioner with this product.
