Want shiny movie-star hair? Think like a Hollywood lighting director and create a light-reflecting surface-which is exactly what the outer layer of hair is when "flattened." (It's no coincidence shampoo-commercial hair is typically pin-straight.) Says Edward Tricomi of the Warren-Tricomi Salon, "Naturally, start with a shine-enhancing shampoo, but then be sure to rinse with cold water-as cold causes everything to constrict." Also, blot hair dry with a towel, as rubbing will "rough up" the strands. Natural-bristle brushes work best at distributing the scalp's oil throughout the hair. Some great luxury home remedies include sleeping on silk pillowcases and "polishing" your hair root-to-tip with a silk scarf.
