Step 8 - Don't boil your hair!
Have a nice and warm, NOT a hot, shower / bath on hair washing days. Hot water damages the roots (leading to more rapid hair loss) and it can strip the hair of it's natural oils, leaving it dry and brittle and send your scalp in oil-overdrive.
Apparently doing a final extra rinse with cold water will make your hair shiny - by cuticle smoothing, but this would be a (hair care) step too far for me, as I hate being cold. Maybe there are some braver people out there willing to try it for the sake of shiny hair...
