Query: Sleep-Inducing at best.

This book poses somewhat of a conundrum. Is it an over-thought monologue on the author's own hair color, or an exceedingly dull scholarly treatise? The answer: it is both! It's a hodge-podge of historical references, anecdotes, and Patty Scialfa. Never delving deep enough into the history, it manages to still lay on what it does say with an all-too heavy brush, dripping with overindulgent prose.In the end, it is sound and fury signifying... the onset of sleep. If you are in need of a never-ending supply of sleep medication, save yourself some money and buy this book. If not, don't bother.
