One often hears that beer, because of its particular mixture of sugars and carbohydrates, is good for one's hair. A group of dermatologists decided to examine the validity of this theory by comparing the hair of a group of people who washed their hair with beer to the hair of a group who used regular shampoo. The researchers found that, in fact, beer contains more chemicals that revitalize hair than does regular shampoo; however, there was a greater incidence of split ends and hair loss in the group that washed their hair with beer.
