(HealthDayNews) -- Here's the easiest diet in the world: Scratch your head and lose 10 pounds.
You're going to lose that weight, whether you want to or not, just by shedding your dandruff, which everybody has to some degree.
Actually, the lifetime loss of that dead skin adds up to about 105 pounds for the average person, according to Jeanne K. Hanson, author of "Your Amazing Body, from Headaches to Sweaty Feet and Everything in Between."
Each square inch of the human body has 19 million skin cells, which routinely grow, die and are replaced.
The reason some people shed more dead skin cells from their scalp as dandruff is because their skin is drier. And that's because they may have too much bacteria or malfunctioning oil glands.
