Most Helpful Positive Review 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.
Most Helpful Critical Review 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.

I was excited to try the shampoo, but it has made my hair a weird dry texture. I have wavy hair and it feels weighed down and frizzy at the same time when I use it. I love Kiehl's, but maybe their hair items aren't for me...
It's ok 2
Heather S from Winchester, VA
Not impressed. It's not bad but it did nothing for my dry scalp or hair. Not a fan of the scent
Great shampoo 5
stepwang7 from NEW YORK , NY
I first tried this shampoo when I went to Equinox, and I was hooked. I just ordered the 1L refill because it leaves my hair feeling so refreshed, smooth, and shiny. With my hair bleached, it has been hard to repair it, but this has helped a lot.

My new go to 5
AnotherWendy from NY
I've tried a ridiculous amount of hair products trying to keep my waist length hair soft, frizz free and not dried out (or oily), while also not giving me scalp issues. This is the best shampoo and conditioner I've come across so far. I'm no longer getting sores on my scalp, my hair brushes thru easily and I'm getting compliments on how nice and healthy it looks. I purchased the big bottle and matching conditioner, and I'm about a third of the way thru so I'm confident it isn't just that different formula effect. The scent is also super light, and doesn't last so I appreciate that it isn't competing with my perfume.

Great shampoo. Smells great and easy on hair. I have been using it for 3 years and plan to continue. Biggest size is a great deal.

This shampoo continues to be my favorite shampoo of all time. My scalp feels fantastic after using it, and it doesn't strip my hair of all natural oils. Thanks Kiehl's!

Heaven in a shampoo & conditioner 5
AminoFab from Fresno
It was seriously hard to take the plunge and invest in the amino shampoo and conditioner — and I'm so glad I did! My hair has never felt this soft in many decades. Im growing my hair out and am trying to wash sparingly to keep the ends from being dried out. I'm finding that one use make extend my wash for to up to three days without getting greasy. My hair feels healthier than ever and is fully hydrated through the ends.
BROKEN LID 1
Luiscemar02 from Woodbridge, VA
I sent this shampoo as a gift to my mom and she received in a horrible box and with a broken lid, I wouldn't expect this from an expensive product like this.
A Newly Added Staple 5
Trina.S from Alabama
I used this shampoo based on the description and the brand. I was not disappointed. The shampoo cleansed my hair without stripping it of moisture. My hair was softer, moisturized, and more manageable. I have 4c natural hair so this worked perfectly. Since my first use I have less single strand knots and tangles in my hair. I will definitely be purchasing this shampoo again
