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.
When demand is elastic, a fall in the price of a commodity results in increase in total expenditure on it. On the other hand, when price increases, total expenditure decreases. It means, in case of highly elastic demand, price and total expenditure move in the opposite directions. Table 4.1: Highly Elastic Demand.
