Apply hairspray in thin layers, mist it on by constantly moving the can as you spray.
The thing to keep in mind about any kind of hairspray (no matter how strong or weak) is that it can make the hair look stiff and shiny – like it’s been glued. So you’ll want to use it sparingly, at least where you can see it later. Apply hairspray in thin layers, mist it on by constantly moving the can as you spray.
