Actual source of the beer head?

Bubbles of carbon dioxide floating to the top are what cause the beer head.Carbon dioxide can be produced one of two ways: naturally via brewers yeast or synthetically by dissolving it under pressure.

Nucleation

The process that creates the bubbles is known as nucleation, and it occurs during fermentation. A small defect in the glass acts as the starting point for the formation of a CO2 bubble. In fact, many beer glasses are purposefully etched, so that the dissolved CO2 has a place to gather and form larger bubbles.
