If you go to the salon for special conditioning treatments, chances are it will include some time under the dryer. I know it's easy to do this when you're already being pampered, but this is actually a step you can take at home.
Why do it? Deep conditioners help minimize and treat styling damage by penetrating, not just coating the top layer of your hair. Although they pack stronger ingredients than regular versions (that's why we use them less frequently), heat actually helps the products work better because it opens up the hair shaft even more.

After applying deep conditioner in the shower, pile your hair on top of your head and wrap it in plastic wrap or use a thin, free hotel cap to seal in body heat. (It's more enjoyable if you put on a cozy robe and, if you're feeling extra ambitious, add a dryer-warmed towel atop your head.) Since the results improve when you also generate heat, speed up the process by blasting a hair dryer on medium over the plastic cap. Oh, and if you can handle it once back in the shower, don't forget to seal off the cuticle with a cold water rinse to leave you with shiny tresses . . .or is that just asking for too much?
