What characteristic of a beard can be improved with the use of a steam towel?

Using a steam towel on a beard primarily improves its softness. The steam from the towel helps to hydrate the hair follicles and opens the cuticles of the beard hair, making it feel smoother and more manageable. This process can reduce frizz and enhance the overall appearance of the beard, contributing to a well-groomed look.

Regularly applying steam to a beard can also provide additional benefits such as loosening any dirt or debris, making it easier to cleanse and maintain. However, while steam can help make the beard feel softer and often look healthier, it does not change the thickness, curl pattern, or length of the beard hair. Those characteristics are primarily determined by genetics and hair care practices, rather than by the application of steam.
