Hair Tonic: What It Is And How To Use It. Hair tonic is an âold schoolâ hair styling product. It makes the hair look glossier (though some say greasier), something which many people viewed as a sign of healthy hair. The oils in the hair tonic also help hold the hair in place, making it easier to style, much like mousse or hair spray.

By JANE E. BRODY. Published: September 13, 1988. A RECENT study suggests that minor fractures of the cartilage in the larynx, which are often undetected and usually untended, may cause permanent damage to the voice. The larynx is the voice box that houses the vocal chords. Fractures can result from a hard blow to the neck, such as might be sustained in an auto accident, a strangulation attempt or a chokehold.
