Kiehl's Since 1851 Amino Acid Shampoo Refill, 33.8-oz.

My hair always feels amazing afterwards, it made my hair very healthy

The Amino Acid shampoo is a staple in my routine, I've used it consistently for about 7 years now. I have very sensitive skin and a very tender scalp and the shampoo is gentle, cleansing, and so moisturizing to my waist-length hair. The lather is so gentle and creamy that I'm able to use it daily. After using both the Amino Acid shampoo and conditioner my hair is SO soft and all my friends comment on how shiny and healthy it is. Love love love these products!

I like to use this product for guests. I like it because of the smell and look of the product.

I have been a customer for MANY years. I am faithful to your products. First, you discontinued the sunflower hair mask. Now, you have discontinued the amino acid scalp treatment!!! Why???? I’m very upset. Please respond!

I have tried many high-end shampoos, and this one truly beats them all. It’s gentle, has great lather, and cleans well. I would say my scalp is sensitive, as I’ve struggled with a bit of eczema and dandruff at times but not while using this consistently. As I’ve aged and lost significant weight, my hair has thinned and become somewhat brittle. In January I decided to come back to this shampoo and conditioner and my hair is the healthiest it has been in years - even my stylist commented on how much better my hair was since she’d last seen me. It’s soft, shiny, and my highlights have not discolored or faded in the four months since I’ve had my hair done.

Great shampoo leaves hair and scalp feeling hydrated, clean, smooth and shiny.

This shampoo meets all my needs and then some. The lather cleanses the scalp without drying. It leaves beautiful shine and silky softness to the hair. I love that it is moisturizing and allows my curls to curl without frizz.

[This review was collected as part of a promotion.] I love the light coconut scent. It lathers surprisingly well for a sulfate-free formula and leaves my scalp feeling clean without drying out my ends. The refill pouch is a nice touch too.

[This review was collected as part of a promotion.] The coconut scent is super subtle, which I love. It has a rich, creamy lather that makes my hair feel clean without stripping it. Plus, the refill pouch is a nice touch.

[This review was collected as part of a promotion.] The coconut scent is super subtle and not fake. It creates a creamy, rich lather that leaves my hair feeling clean but soft, not stripped. My scalp is way less itchy too.
