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.

Rated 5 out of 5 by from Fabulous shampoo Made my hair bouncy and full of body. It did an excellent job of removing styling product buildup without stripping or drying my hair. Unfortunately it's quite pricey so it's not an option for regular use.

Rated 5 out of 5 by from Best Shampoo, Ever! I love this shampoo! I first had a taste of this fine shampoo when I enrolled at the Equinox gym. Just knowing I was going to be able to use as much Kiehl's products as I want made me sign up in a heartbeat! Anyway, this shampoo not only leaves your hair smelling amazing, it also leaves your hair soft and shiny. I've gone though so many shampoos (expensive & cheap) and the Amino Acid is the best. You don't need much, just a small amount and it will clean your hair. I accompany this shampoo with the Formula 133 conditioner. They're a match made in heaven.

Rated 5 out of 5 by from My favourite Kiehl's Shampoo This has been my main shampoo for over 5 years now. I will sometimes try a different shampoo because I want to mix it up scent-wise, and because I will sometimes wonder if I'm missing out on a product that will work better for my hair (mainly because as I'm getting older, my hair texture is changing a bit). I always keep coming back to this shampoo, as it gives me the best and most consistent results. First of all, I love the coconut scent. Second, this shampoo never dries out my scalp, and is not too harsh on my (getting finer) fine hair. I have hair that tends to be frizzy (it is also naturally curly-ish, but I wear it straight). This shampoo supplies a decent amount of moisture and shine without giving me an oily scalp. I have tried other volumizing shampoos (even the Ultimate Thickening and Rice & Wheat), but have not liked them more overall than this shampoo, so I'll continue to stick with it! This would also probably be a great family shampoo, as it works well for a lot of different hair types.

Rated 3 out of 5 by from Not works for me I have curve and oily hair, so I feel that this shampoo can't wash my hair throughly. My hair will turn to greasy and sometimes even feel itch. But this shampoo smells very good. It has nature ingredients which make me happy. For me, I usually using strong clean shampoo first and then use this shampoo.

Rated 5 out of 5 by from You'll love this shampoo! This shampoo smells wonderful! Like a tropical vacation! And the scent lasts all day. Both my husband and I use it regularly. It lathers well and adds a nice fullness to the hair.

Rated 3 out of 5 by from Normal shampoo didn't work for me This shampoo didn't work for me. Hence trying out the ultimate thickening shampoo now.

Rated 5 out of 5 by from Kiehl's Classic Amino acid shampoo is a good basic shampoo. It works well for my normal hair. I love it for 3 reasons: it's Kiehl's; it has a great, light coconut scent; and it gives a great lather.

Rated 5 out of 5 by from Awesome Shampoo I love the way this shampoo makes my hair feel; just wish it wasn't soooo expensive, even though it is, I will still buy it!!

Rated 4 out of 5 by from good but not perfect The product is very good and that's why I bought it. But unfortunately when I received it, it was opend and the shampoo flowed out.

Rated 5 out of 5 by from Favorite shampoo Since trying this as a sample at a hotel in Chicago I have not been able to return to mere mortal shampoos. It is more pricey than other products I've tried from other companies but it is worth the cost for the consistent clean it produces without over drying my long and often abused hair.

Rated 5 out of 5 by from Excellent I got a hair problem since 1 years ago, when I took a shower, my hair loss a lot. Some people said that if the shampoo has silicone would damage your hair. So I started to pay attention to find good and health shampoo, I like this shampoo after I use for 1 month later. My hair loss problem got solve. And after one month, I feel my hair is soft than before. I recommend to my friends. And they love it. I have to say the customer service is excellent, I ordered online, when I got it the shampoo with spills, so I sent email, the customer service return my money. That is the reason I love Kiehl's.

Rated 5 out of 5 by from Buying my second bottle - the bigger size! I bought this shampoo and the Amino Acid Conditioner on a whim. I had been using Biolage, but it makes my hair sticky after a while, so I wanted a change. WOW, am I impressed! It doesn't dry out my ends (I have waist-length, fine, thinnish hair) and it takes so little to get my hair SOoooo clean. My hair went from sticky to volume and shine in one shampooing, and I was hooked. I have been using it every day for 3 months now. I love the scent, I love that it has NO DIMETHICONE/silicon (which is terrible on my hair), and it has no color to stain my hair ( my hair is white, and I have had issues with the dyes used in other products "tinting" it.)

Rated 5 out of 5 by from Yup. It is worth its weight in gold. I am a die-hard Wen hair products fan. I wouldn't have even tried this shampoo, but I wanted to fulfill an order minimum on Kiehl's site, so I threw it in my basket. Wow, am I glad I did. This is now one product I will never stop purchasing!!! I am 33 with medium-coarse mid-back length hair and I get it colored (weaved) to give me that beachy, highlighted look every 5 or 6 weeks. This shampoo, after one single use, left my hair smooth, shiny and bright. Shockingly, after a blow dry (which took at least 5 minutes less than usual), I did not need to straighten my hair with the flat iron. Oh happy day. I am a new fan and I will keep buying. Wish it was a few bucks cheaper though...

Rated 5 out of 5 by from Smoothest, cleanest shampoo I've ever used I had been quickly disenchanted with a shampoo and conditioner I had bought at The Body Shop, and was looking for a new product. I dropped by the local Kiehl's to replenish my facial cream, and decided, I love their skin products - why not try their hair products as well? I have straight-ish, shoulder-length, non-processed Asian hair, gets a bit greasy after a couple days of washing, and this shampoo is perfect for my hair type. It lathers easily and my scalp and hair feel very clean and refreshed after shampooing. I finish it up with the Amino Acid conditioner, and afterwards I don't even need to add any more hair products - my hair feels so silky and I can actually see that it's shinier. Also it smells so good without being overwhelming or bubblegum-y. I think I will be sticking with this product for a long time.

Rated 5 out of 5 by from Love the shine I got a gift box last Christmas with small bottles of the Amino Acid Shampoo and Conditioner and loved it, but didn't think I was the type to pay so much for hair stuff. After a few months back with my regulars, I realized the price difference wasn't really that much and I really loved the effect. I made the buy a few weeks ago and am so glad I did. My hair is so shiny and I've gotten a lot of compliments the last few days. And the smell is to die for. Would absolutely recommend for anyone with thick hair. Cleanses well without drying out or being heavy. Seriously, the best shampoo I've tried.

Rated 4 out of 5 by from Great every day shampoo This is a great shampoo. I use it nearly every day in combination with the Olive Oil conditioner. I have very coarse thick hair, and this does a wonderful job at adding moisture and keeping my hair soft. The fragrance is very nice but subtle, and the texture/lather is very pleasant. As I said, I use this shampoo nearly every day and have found it very nourishing.

Rated 4 out of 5 by from Best All-Around A great shampoo for everyone in the house, including slightly damaged/highlighted locks.

Rated 5 out of 5 by from Softened my hair I just bought this shampoo and have only used it once so far. I have thick hair and other shampoos have been leaving it feeling either coarse or weighed down. I could tell even while I was lathering with it that my hair felt softer. And it still felt so soft after blow drying. I see more Kiehl's products in my future.

Rated 5 out of 5 by from Best Shampoo EVER! I love this shampoo! I've tried several high end products, since the drugstore brands dried out my ends while weighing down my oily hair. This balanced my hair/scalp and gives me shine, and volume! On the days I don't wash my hair I use dry shampoo and this shampoo really takes all the gunk and build up without stripping the hair. I'm almost done with my first bottle and will purchase the larger size
Date published: 2012-11-23
Rated 5 out of 5 by from BEST BEST SHAMPOO EVER, everyday use doesn't strip hair, gentle cleaning keeps hair soft but does a good job cleaning scalp. I have used this after bikram yoga, swimming, coloring my hair, when my hair is long, short, flat ironed or naturally wavy. I have thick coarse hair but does a good job moisturizing but not weighing down or flattening. Can't say enough. I've used so many high end shampoos but I buy this one by the barrel.

Rated 5 out of 5 by from Another great Kiehl's product My entire family uses this shampoo - we all love it. It's gentle enough for the kids, yet cleanses very well.

Rated 5 out of 5 by from Miracle Shampoo! This shampoo is killer (in a good way, of course!). I have come to rely on it more and more since I was converted to a Kiehl's addict! I love how shiny and luminous my hair looks after I use this shampoo. And don't even get me started about the scent! The scent is delicious, and the shampoo in general is very gentle, which is always a plus!

Rated 3 out of 5 by from The TRUE is.... Many people recommend Amino Acid Shampoo to me, so I bought it! First of all, I need to claim for a few points. I have fine hair. I finish the whole bottle before I give this review. What a great disappointment. I didn't see any change on my hair. It doesn't make my hair shiny. It just like a normal hair shampoo you can buy in drugstores. However, I still give this product 3 starts because many of my friends like it. They told me this shampoo help their hair grow faster. (REALLY?)

Rated 5 out of 5 by from OMgosh Such a great product. I found Kiehls products at my gym and have been addicted ever since. It's like I have a new head of hair that's not even mine...is so gorgeous. Too good to be true!

Rated 5 out of 5 by from Amino Acid Shampoo Mild enough for everyday. Leave my hair very easy to manage. I always use it with the conditioner.

Rated 5 out of 5 by from Smells fantastic and gently enough for my baby! I bought this on a whim after reading some great reviews. It is everything I wanted it to be! I have fine hair and this is very gentle (I use it on my kids and baby too), and I LOVE the smell! I know that doesn't have anything to do with performance - but it really enhances my shower experience. It's a little expensive - but not out of line considering how long it lasts me. Excellent shampoo!
