If you know the name of the shampoo check to see if it had cones. Cones will make my hair go flat and lose curl if I don't sulfate poo it out.
Now maybe that's not the case but it's better to find out than be frustrated by your hair for longer when you could just use a shampoo with no cones and then start your routine over again.
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
