Take another look at the passage:
Like amber honey, Helene's long hair dripped over her shoulders and spilled down her back. Styling products, moreover, made the tresses as sticky as pancake syrup. Catching pieces of thread, feathers, dust, and even an occasional insect that buzzed too close.
You chose the second part, Styling products, moreover, made the tresses as sticky as pancake syrup. This part has a main clause: products is the subject; made is the verb. A fragment will not have a main clause.
