I hear that hairspray is not only used for hair. Here's one way:

Hairspray can be used as a run stopper! If you get a run in your pantyhose, spray it immediately to prevent it from getting any longer.

Can you suggest any other uses?

it's works great on spiders.

mace is illegal in some states but you can use it if attacked, if your coloring your hair and get it on your clothes spray hS on it til you can wash the clothing
