Clogged Hair-Spray Pump

Cause: “A clogged nozzle typically occurs when a small amount of resin, which is what gives hair spray its stickiness and holding characteristics, dries and sticks to the exit hole in the sprayer,” says Mark Frey, a products marketing director.

Cure: Hold the nozzle under warm running water, then remove the residue with a tissue or use a toothpick to gently scrape away any debris that is lodged in the hole.

Preventive Tip: After each use, run the nozzle under warm water, then dry with a tissue. Store hair spray with the cap on in a cool, dry place. If you use hair spray only occasionally, buy small cans to avoid buildup in the nozzle over time, says package designer Kevin Marshall.
