Hairspray is wonderful for your hair. Not so great on the floor, sink, walls, mirror, and counter where you get ready every morning.
Unless you are diligent to go outside everytime you spray your hair, it’s a good bet hairspray overspray is landing on the nearby surfaces of your bathroom.
When allowed to build up day after day, hairspray can be tough to remove. What you need is a solvent that will melt the hairspray without harming the surfaces. Bonus points if that solvent does the job then dries quickly without leaving streaks.
