"Good quality hair mousse has nutrients that enrich the hair while lifting it. Good quality hair gel has vitamins and fatty acids that coat the hair strands."
"Nutrients that enrich"? Any wisegeek would know that anything trying to treat treat the hair outside the scalp does no such thing as nourishing or enriching hair.
Anything that you put on your hair goes on the hair. It may cause the hair to be more or less curly, or it may damage the hair, but it is not going to make the hair itself any better.
