Definition: In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: This conditioner is too heavy, and the accompanying shampoo isn't strong enough to wash it out. After two uses, my hair was stringy and oily underneath, and my scalp was itchy. On a third use, I tried just using the shampoo but couldn't get my hair clean and had to use another product to rinse out the build-up. Disappointing as the product is clean and smells lovely. I have fine hair. Perhaps this would work better on someone with a different hair type.
Output:
negative
