How do I know if I have dry hair?

how do I know if I have dry hair?  I ask this because alot of products can make your hair feel extra shiny or greasy and I want to make sure I'm using the right products, I brought shea moisture curl enhancing smoothie & a review said if your hair isn't dry it will make your hair feel greasy?
