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.
The demand for a good is said to be elastic (or relatively elastic) when its PED is greater than one (in absolute value): that is, changes in price have a relatively large effect on the quantity of a good demanded. When the price elasticity of demand for a good is perfectly elastic (E d is â â), any increase in the price, no matter how small, will cause demand for the good to drop to zero. 2  Hence, when the price is raised, the total revenue falls to zero.
