Hairspray
To dream of hairspray represents a concern with avoiding embarrassing yourself having acted or thought poorly. You may be using certain actions or habits to force yourself to stay on the straight and narrow. Habits or action you could take to make certain that you look good or make a good impression.
Negatively, using hairspray in a dream may be a sign that you are overly concerned with your looks and image. You may care too much with what others think of you. An excessive need to be perceived as perfect or of sound mind. Uncomfortably controlling yourself or holding yourself back in order to make someone like you.
