I'm not sure if you mean you got two inches cut off or that you went from BSL to 2 inches above your shoulders??
If you got a lot cut off you probably need to adjust the amount of product you're using, conditioner and styling products. It's also possible that your new growth has slightly different properties and needs different care than you're used to. Also wavy hair often needs to be a certain length to form a full 'S'. I'm just kind of throwing stuff out there.
My other thought is that maybe its due to something the salon put in your hair, a shampoo or serum with cones or a heat protectant spray? If they put anything in your hair you don't know for sure is CG its probably worth it to clarify with a cone free sulfate shampoo give it good dose of your regular conditioner and see how it reacts.
