what a difference a month makes using the Neutrogena scalp serum

The video effectively uses a clear before-and-after format to visually demonstrate the product's efficacy, leveraging a common and relatable concern (hair health) to capture viewer interest.

The video shows a side-by-side comparison of the creator's hair on July 13th and August 6th, highlighting the positive difference made by using Neutrogena scalp serum. The creator is brushing her hair in both clips, demonstrating the change in hair health over a month.

Neutrogena scalp serum ACTS: it is used by the creator to improve hair health, and the video shows the results of using it. Removing it would change the video's purpose and outcome. Neutrogena is the brand name for the serum.
