This hairspray for frizzy hair was designed to not weigh the hair down, or cause build-up on the hair. If for some reason you do feel like you have build-up after using it, avoid using too much hairspray the next time. A good indication that you may be using too much is if your hair feels wet. If hair is feeling wet then cut back on the amount of product usage. Use a clarifying shampoo if you feel that the build-up is not easily removed with your regular shampoo.
