Inflatable pillow valve leaks?

I use inflatable pillows. After about 3 months, the valve begins to leak, and you have to keep blowing it back up. It's the usual valve, a round plastic stud goes into a short, thick tube. How can I fix it so it won't leak?

Cheap pillows made in China. Throw them away. They are not fixable.

You can help it with something thick and gooey like maybe a thin coating of Vaseline or maybe hair gel. Also, are you sure you.re not over-inflating? My experience comes from air mattresses and camping. I've learned that a highly inflated "extra firm" mattress is much more likely to deflate.

You might be able to tighten the valve. There are inexpensive tools for this.
