This is my favorite shampoo, and I have tried at least ten this past year alone. I have very fine, highlighted hair, and this shampoo, along with the Olive Oil Conditioner, have improved the condition of my hair more so than all prior products. I tried the Kiehl's Amino Acid line first, and didn't care for it, as it made my hair limp, and lifeless. This line had the opposite effect. It gives my hair plenty of moisture, while also giving it body, and shine. It's a fantastic line, and I highly recommend to those with fine, processed/dry hair.
For the first time my dry hair problem is solved with the Kiehl Olive Fruit Oil shampoo and conditioner, the satin leave in conditioner before drying and the smoothing oil! Nothing, including the expensive brands, has worked in the past. Thank you Kiehls!!
