The brand is lying about something, or at least misrepresenting it. When I read a bottle of shampoo or moisturizer or other beauty product, I always perceive a dark subtext. The words haunt me. It comes across as humorous to the reader/audience, but in fact the words really do make me a little bit queasy. Nothing is as easy or natural as consumer brands want us to think - no problem is as resolvable. Your hair will fall out, eventually. Yet we do have these brands, and we line our shelves with them. There's an inherent irony.
