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.
Example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Example solution: negative
Example explanation: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

Problem: I really like this shampoo! I have fine, 3A curly hair and never heat style, but I did in the past and am trying to help my hair health with products like this one. I love that the shampoo is free of harsh sulfates but lathers so nicely. It feels like a normal shampoo - very luxurious and smooth. My hair is left moisturized out of the shower and smells lovely! My boyfriend likes it too. We use it with a SheaMoisture deep conditioner after, and I always work leave-in conditioner into my hair after showering. Another comment - I love this size. It will last awhile and the pump is convenient! It takes 1-2 pumps for my medium-length hair.
Solution: positive
