How is the best way to use CHI Silk Infusion?

I have that! I love it! And I had the same problem the bottle gave no instruction on how to use it. I've used it in my hair while it's damp because thats how i used my moroccan oil before. Then I would finish blow drying and spray my chi iron guard n once its dry then straighten/curl! I think you probably can do it when its dry.. im sure it wont make much of a difference but i prefer it damp.
