Causes of Hair Loss. First your doctor or dermatologist (a doctor who specializes in skin problems) will try to determine the underlying cause of your hair loss. The most common cause of hair loss is hereditary male-or female-pattern baldness. If you have a family history of baldness, you may be susceptible to this type of hair loss.
Demand Elasticity - the degree to which changes in price effect changes in demand. Demand is elastic when a small change in price effects a large change in demand. Such products, that show great variability in demand are known to have elastic demand.
Elasticity of demand = % change in quantity demanded / % change in price. It is not to be confused with the slope of the demand curve. The slope of the demand curve remains constant; however, the elasticity of the demand curve changes as you move along. The only curve that has a constant inelastic demand is a vertical demand curve. Any change in price will result in no change in quantity demanded.
