Why it worked
The video likely performed well due to its aspirational "grown women hair era" theme and the visually appealing, voluminous hair. The "more layers = better hair = sexy hair" equation provides a simple, desirable benefit, and the subtle product placement via the username makes it feel less like a direct advertisement and more like a recommendation.
Summary
The video shows a woman with long, voluminous black hair, styling it and touching it. Text overlays indicate "MORE LAYERS = BETTER HAIR = SEXY HAIR" and a username "@DIVINEEXTENSIONSS".
