How thick should a hair bundle be?

A hair bundle should be thick enough to provide adequate coverage but not so thick that it looks unnatural or bulky. 

The thickness of a hair bundle will vary depending on the individual’s natural hair texture and density, as well as the style of the wig or extension. 

For example, a straight wig may require fewer hair bundles than a curly wig. Ultimately, it is up to the wearer to decide how many hair bundles they need to achieve their desired look.
