Make sure your screws stay where you put them
With enough product, even hair can become as hard as cement. After all, keeping things in place is exactly what it was designed to do. But what if that principle applied to other non-organic objects? Screws often come loose due to vibrations from planes passing over your house, or traffic trudging along if you live close to a busy street.
There is no need to accept having shelves and cupboards that fall over. Try covering the screws in hairspray before you push them into whatever material you are trying to fasten. Then, spray them again once they are in place. Tables, chairs, and shelves will stay secure in their position for extended periods of time.
