Longshan spring original pulp beer manufacturer will explain to you:

There are many conditions that can affect the thickness of a bubble, including temperature (the lower the temperature, the more bubbles), lipstick (some lipsticks can make bubbles disappear quickly), and cups (if the cup is etched, the more bubbles there are). That's why some wineglasses manufacturers deliberately etch tiny etches into the bottom of the glass to create bubbles. Some beer makers have also proposed etched cups that would allow people to drink beer with a better head experience.

If you go to an Irish bar, you might find another way to keep the head of beer in the glass longer: pour it twice. Often used in Guinness sommeliers, the method is simple: pour the beer two-thirds of the way through the glass, wait a few minutes for the glass to fill up, and you'll find there are more bubbles.
