Rated 3 out of 5 by miomite okay, but not something i would buy again
i have been using this shampoo for about two months now, but havent seen any noticable effects. the fact that it says right on the bottle that it contains LOTS of silicones is not pleasing. it cleans my hair and scalp well, but leaves my hair a bit dry and brittle, especially after a few uses.
i'll be sticking to my dry shampoo for volume, and get comfortable with my natural, less thick hair

I love this shampoo. It smells great and gives my thin, short bob excellent body. It cleans without over-drying and refreshes my scalp. I've been using it for over two years and am still happy with it. I just recently had balayage done on my virgin hair, so I bought the Amino Acid shampoo because it sounded like it would be more gentle on the color. Although I can't decide which I would take to a desert island, Ultimate Thickening will always get my endorsement.

I've been using this product for two weeks, washing my hair every other day, and I have never had my hair feel this soft after a shampoo. I can't tell too much yet if it is making my hair thicker, but this is such a great smelling shampoo that makes your hair shiny and soft afterwards. I'm sure within another week or so, I will see the effects of the thickening!
Rated 4 out of 5 by HWIrish Excellent product that performs well.
I have always had rather fine hair but this product does just what it's advertised to do. My hair is now much fuller and has more body than it ever has before. My only complaint is that I can't get a larger bottle.

Was a bit hesitant that this would have any noticeable effect, but was happily surprised. I use it daily and have received comments about my hair not looking as thin.
It works!! Great product and doesn't take much!!!

This product might fortify thinning hair, but it definately doesn't thicken it. As pleased as I am with most Kiehl's products, this is not one of them.
Rated 5 out of 5 by teafortwo Great for thin hair!
I have very fine, thin hair. On top of that, my hair fell out like crazy every time I washed it. It was like a bird's nest in my shower! Not with this shampoo though. I've been using this shampoo for about 3 months, and consistently notice that the bird's nest is reduced to only 1/4th of what used to be. The shampoo also adds texture to my hair, making it look and feel a little thicker (Just don't expect it to turn your hair into Lucy Hale's or anything. The effect is slight.). It cleans very well also. It's kind of like a clarifying shampoo, but not as harsh. I wash my hair every 3-4 days so it doesn't feel like it's drying out my hair. I'm so glad I've found this product. It saved my hair!

My hair is very thin, fine, and fragile. As a result it can look oily and "thickening" products just weight it down. This shampoo feels luxurious on, and from the first application, my hair looked noticeably healthier.
