Brush up on hair science at this fun site sponsored by French beauty products manufacturer L'Oréal. You can find facts even your hairdresser doesn't know by combing through pages on hair growth, structure, color, and ethnic differences. For example, hair doesn't actually turn gray as we age; it loses pigment, which causes it to appear grizzled. Other pages explain what scientists can deduce by analyzing the composition of hair. (Napoleon was probably poisoned with arsenic, and Beethoven didn't die from syphilis.) The site also plucks some revealing close-ups. Victims of split ends, take heart: Even the most lustrous locks appear gnawed under the microscope.
