I change my shampoo about every two to three months and the original reason that I bought this product is becasue it was only three dollars. I brought it home and used it and first of all the smell was amazing, it is very tropical and makes you feel clean. I lvoe it. Second, there is lather but not too much, it doesnt make your hair feel like straw and that is always a plus for me. I have dyed my hair a lot and it is pretty damaged. This product makes my hair feel very smooth and it is very shiny. It is much easier to work with and straighten.  The smell of the shampoo lasts all day you can smell...
