Is stubble and scruff the same thing?

Stubble and scruff are often used interchangeably, but they can refer to slightly different concepts. Stubble typically describes the short, coarse facial hair that grows after shaving, usually within a day or two. Scruff, on the other hand, generally refers to a more unkempt or rugged appearance of facial hair that might be longer than stubble but still not full beard length. Both terms evoke a casual, masculine look, but the specific length and grooming can vary.
