Just because some loudmouth Millennial rolls his eyes and dismissively says, “That’s the oldest trick in the book!” (with an implied “old man!”), doesn’t mean it’s not a good trick. I used one of the oldest tricks in my lexicon recently in class: the hair shake. This works well with people who have long hair that is looking too stiff. Have the subject/model throw their head forward and shake their hair, then quickly sit up, letting their hair fly back. Nine times out of ten it will result in their hair looking wild, free, fun, beautiful. Don’t let them touch it – it will feel strange to your model because they never comb or brush it that way, but it will look amazing.
