Actors, musicians, dancers, and models use personal branding and head shots as part of their professional portfolio to showcase their look and style to potential agents, casting directors, and producers. Head shots may also be used for promotional materials, such as posters and brochures, and on social media platforms to help build a following.  Head shots may be required when applying for roles or auditions, as they provide a clear and professional representation of the person's appearance.
