Kiehl's - Amino Acid Shampoo, Cleanses & Softens Hair

This is the best shampoo I’ve ever used. It leaves my hair feeling soft and shiny after every wash! It cleans thoroughly without drying out my hair and it helps it looking healthy.

Great for curly hair, nice and subtle smell. Leaves hair clean and soft but not dry. Effect lasts. Lately I was wondering why my hair looked so unmanageable, and it turns out that's because I ran out of the product and didn't re order straight away... Re ordered now.

Best shampoo ever. Keeps my hair healthy and moisturized.

I don’t normally write a review but I must at this time! I had irritated scalp issue for a while. I’ve used so many different types of products that are no fragments in it, for sensitive skin, made of all natural, and etc. Basically throwing money to search and end my pain. Some made partial progress but it always came back. Mad mad itchiness was one major problem, red irritated scalp skin and pimples..and the other was burning sensation while drying hair. This product , gives nice coating sensation, not heavy oil residue feeling, very minimal fragrance scent but you can still notice some. I am highly satisfied and recommended if anyone suffering similar problems as I listed above ~ I used about a week so far and seeing this significant improvement already!

I am obsessed with this shampoo! My hair has never felt this soft and healthy. I’ve struggled with frizz for a while, but after just a few washes, I noticed a huge difference in the shine and texture. It lathers beautifully and feels like a luxury spa experience at home. It’s worth every penny—I've already recommended it to all my friends!

Bought I presumed, a high quality shampoo that smells wonderful and hair feels clean and soft. My only qualm is that there’s citric acid, which I’m developing a sensitivity to. Investigated citric acid and to know why.

This is my favorite shampoo. What else to say. Nice, low key smell. Effective at cleaning without leaving my hair feeling like the natural oils are being stripped out. The only con is that it is a bit pricey. But I feel I am getting the premium you pay for with this shampoo.

The best I've used, among some other similar-tier shampoos like Olaplex, Kiehl's leaves hair with a certain softness that other shampoos don't. My hair feels stronger and scalp is unirritated after months of use. Would highly recommend

Ich schwöre seit Jahren auf Kiehl's Ultimate Thickening Shampoo für mein sehr dünnes Haar; leider ist dieses anscheinend nicht mehr erhältlich, und ich hoffe nun auf das Amino Acid Shampoo als adäquaten Ersatz.

product leaked a little upon delivery but still one of the better shampoos ive used to date :)

Für meine feinen glatten Haare das beste Shampoo

Me encanta su aroma tropical a coco y al parecer es de buena calidad.

It is an expensive product , but when you see it you will realise the top quality, and you will appreciate how it changes and improve your hair.
