Product placement
Muze Hair (a) acts: the creator is a celebrity hairstylist who owns this brand, and the video demonstrates a custom wig cut, color, and style performed by her on a client, which is the core service/product offering of her brand. Removing the brand name would change the video from a demonstration of her professional work and brand expertise to a generic hair video. Lost Angels Agency (b) appears: a repost stamp/credit for the videography, removing it would not change the video content.
